    CERTIORARI TO THE INTERMEDIATE COURT OF APPEALS
    (CAAP-11-0000775; CASE NO. AB 2009-158 (M) (7-07-10239)
    January 23, 2014
    RECKTENWALD, C.J., NAKAYAMA, ACOBA, McKENNA, AND POLLACK, JJ.
    OPINION OF THE COURT BY POLLACK, J.
    This appeal arises out of a workers’ compensation claim
    filed by Petitioner/Claimant-Appellant Lynedon Van Ness (Van
    Ness) with the Director of Labor and Industrial Relations
    (Director), in which Van Ness sought compensation for the
    aggravation of his asthma resulting from his exposure to vog at
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    work.1
    The Director denied his claim, and the Labor and
    Industrial Relations Appeals Board (LIRAB) affirmed the decision.
    Van Ness now seeks review of the January 31, 2013 Judgment of the
    Intermediate Court of Appeals (ICA), affirming the LIRAB’s
    decision.    For the reasons set forth herein, we hold that Van
    Ness is entitled to compensation pursuant to Hawai#i Revised
    Statutes (HRS) § 386-3(a), governing an injury by disease that is
    proximately caused by employment.          Accordingly, we vacate the
    ICA’s judgment and the LIRAB’s decision and remand to the
    Director for a determination of the amount of compensation to be
    awarded.
    I.   BACKGROUND
    The following facts are taken from the record and from
    Van Ness’s testimony at the LIRAB hearing.
    A.
    Van Ness was employed by the State of Hawai#i,
    Department of Education (DOE), as a technology coordinator at
    Lahainaluna High School (Lahainaluna), on the island of Maui,
    from July 2005 to November 2006.          He had a history of “mild
    1
    “Vog is a term that refers to volcanic smog. It is . . . caused
    by a combination of weather, wind conditions and volcanic activity. Vog
    becomes thicker or lighter depending upon the amount of emissions from Kilauea
    volcano [on the island of Hawai#i], the direction and amount of wind, and
    other weather conditions.” Important Information About Vog, Governor of the
    State of Hawai#i, http://governor.hawaii.gov/emergency-information/important-
    information-about-vog/ (last visited Dec. 11, 2013). See Merriam-Webster,
    http://www.merriam-webster.com/dictionary/vog (last visited Dec. 12, 2013)
    (defining “vog” as “air pollution caused by volcanic emissions”).

    persistent asthma” that he had largely controlled through
    avoidances and prescribed medications.
    In 1989, Van Ness was employed by the DOE as a school
    teacher on the island of Hawai#i.         While teaching in Kona, Van
    Ness was exposed to vog and “had difficulty breathing and
    required courses of systemic corticosteroid for rescue along with
    regular controller medication.”
    In 1991, Van Ness was transferred to a school on the
    island of O#ahu and began receiving respiratory treatment from
    James M. Sweet, M.D. (Dr. Sweet) and Russell M. Tom, M.D. (Dr.
    Tom).   “He was tested and confirmed to have allergic potentials
    to multiple inhalant allergens including dust mite and mold
    spores.”    He was placed on “a several-year course of
    desensitizing immunotherapy and had [a] favorable outcome.”
    From 1995 to 2001, Van Ness lived in Idaho, during
    which he “had few symptoms of allergic-respiratory disease.”
    Van Ness returned to O#ahu in 2001 and was employed by
    the DOE as one of two technology coordinators at Leilehua High
    School.    In October 2004, during a trip to California, Van Ness
    was hospitalized for a diaphragmatic hernia.          He also contracted
    pneumonia during his treatment.
    In July 2005, Van Ness was transferred to Lahainaluna
    to work as the technology coordinator.         Lahainaluna had
    approximately one thousand students and one hundred and fifty
    staff members.    Van Ness was the only technology coordinator at
    -3-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    the school and was responsible for maintaining and repairing the
    technical equipment for the entire school.
    Van Ness testified that Lahainaluna is located on the
    side of a mountain, at the end of Lahainaluna Road.           Lahainaluna
    Road “starts right at the ocean, goes a couple blocks, and then
    goes up the hill past the intermediate and elementary school to
    the high school.”    Lahainaluna’s campus was situated at the
    highest point that Lahainaluna Road reached on the mountain.
    Van Ness testified that due to the school’s location,
    the school buildings and classrooms are “kind of spread out and
    put up against the sides of the mountain in various locations,”
    and there are “stairs that go up the side of the hill.”            Van Ness
    estimated that between campus buildings on the lowest and highest
    point of the mountain, there was an elevation difference of a
    “couple hundred feet.”
    Van Ness testified that the staff was not provided with
    golf carts for transportation, and due to the steepness of the
    campus terrain and the lack of paved roads, it would have been
    impractical to attempt to use golf carts for transportation
    around the school.
    Van Ness’s office was located in the school library,
    which was situated at the highest point of the campus.            Van Ness
    was required to repeatedly climb up and down the school stairs
    daily in order to service the classroom computers at the lower
    parts of campus.    He explained that there were fifty to sixty
    -4-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    stairs at the base of the library, another eighty stairs to reach
    the next level of buildings, about “three or four floors” down to
    the parking lot, and then another “hike down” to the final
    section of buildings.     The stairs “wrap[ped] around trees” and
    went “up the side of the hill.”       There were also “switchbacks,
    where you go up one way and go the other direction.”
    Van Ness testified that he was forced to stop to catch
    his breath as he traveled uphill to his office from the lower
    campus.    It took “about five minutes to go down to [the]
    admin[istration] [building], [but] like 20 minutes to come back.
    It’s the elevation change in the stairs.         It takes quite a bit of
    effort.”
    Van Ness was generally present on campus for seven to
    eight hours a day.    Although his office was air conditioned, Van
    Ness estimated that he spent less than five percent of his time
    at work in his office.     When he was not in his office, Van Ness
    worked in non-air conditioned environments “all over campus,” in
    buildings with “louvered windows” and “fans . . . inside to keep
    the air circulating.”     Although many of the classrooms and
    offices were equipped with air conditioners, most of the units
    were turned off and the louver windows were left open.
    Van Ness explained that his experience working as a
    technology coordinator at Lahainaluna was different from his
    experience working in the same position at other schools because
    he was required to engage in a significant amount of physical
    -5-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    activity outside.    Additionally, Van Ness testified that the
    computers at Lahainaluna required more maintenance than computers
    at other schools because they were exposed to more dust and dirt
    as a result of the buildings being non-air conditioned and the
    windows being left open.      Van Ness frequently cleaned and
    replaced the computer filters, which were clogged with dust.
    Many computers “overheated” because of the lack of circulation
    and the accumulation of dust.       At schools on O#ahu, he focused on
    upgrading the computers to “run faster and more efficiently,”
    whereas at Lahainaluna, “it was more an issue of keeping them
    running.”
    While Van Ness worked at Lahainaluna, he lived in an
    air conditioned home in Kihei.       The air conditioner had a built-
    in filter.    In addition, Van Ness had several “Bionic Breeze”
    filter units placed around his home.        The units were high-
    efficiency particulate air (HEPA) filters, and had been
    recommended by his doctor.      Van Ness also had a HEPA filter in
    his car.
    Van Ness testified that there was a significant amount
    of vog on Maui from late October 2005 through April 2006.             On
    days when the vog was severe, he was unable to see the
    administrative building “halfway down the campus” from the
    library.    Van Ness also stated that a film of volcanic ash would
    accumulate on his car and windshield, requiring him to use the
    windshield wipers to keep the windshield clear while driving.
    -6-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Van Ness did not have any problems with volcanic ash
    inside his car or his home.      He testified that while living on
    Maui he spent little time outside, other than when he was at
    work, as he was “not much of an outdoors person” and “there
    really wasn’t much to do there.”
    Van Ness testified that in late 2005, his exposure to
    vog at work affected his respiratory condition by reducing the
    amount of air he was able to breathe.        When the vog was severe,
    he experienced “a lot of coughing, wheezing.”          He also caught a
    cold and contracted bronchitis.       Van Ness’s shortness of breath
    worsened when he walked uphill to his office from servicing the
    computers in the lower campus classrooms.         Van Ness described the
    pain from coughing as “incredibly sharp,” “like a stabbing pain.”
    Additionally, Van Ness explained that when he tried to
    move around, he would start sweating, his heart began “pounding a
    lot,” and his face “[got] all red.”        Because Van Ness had to walk
    to his office and assigned parking spot located at the top of
    Lahainaluna’s campus, “it caused a lot of . . . issues with
    strength, a lot of issues with just being able to breathe.”             He
    explained:
    [The vog] basically reduced the amount of air I was able to
    breathe. And started wheezing and coughing. Real shortness
    of breath. And obviously the more that happened, the worse
    it got, to where I basically went level to level and took
    breaks before I’d continue all the way up. It’s steep.
    There were times when I would drive. It was easier to drive
    from the library down, around the campus, up to admin, than
    to actually walk down there.
    Prior to the period of severe vog, Van Ness was able to
    control his asthma condition with a regular inhaler, which he
    -7-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    usually did not need to use.       Van Ness was prescribed enough
    medication to last thirteen months.        While living on O#ahu, Van
    Ness never exhausted the entire thirteen-month supply and only
    refilled his prescription when the inhalers expired.
    While working at Lahainaluna in late 2005, however, Van
    Ness exhausted his supply of inhalers before his prescription
    expired, and he was frequently required to refill his inhalers at
    the pharmacy.    However, his inhalers and other medication were
    not helping with his breathing.
    On December 23, 2005, which was a work holiday during
    Lahainaluna’s winter break, Van Ness traveled to O#ahu to see Dr.
    Tom, his primary care physician, about his condition.            Dr. Tom’s
    clinical notes include a reference to “vog,” although some of the
    handwriting is illegible.      Dr. Tom wrote that Van Ness was
    experiencing difficulty breathing and coughing.           Van Ness
    testified that after performing x-rays and tests, Dr. Tom
    diagnosed him with chronic bronchitis.
    Van Ness testified that following his visit with Dr.
    Tom, he was placed on “light duty” at work, which required that
    he “stay out of the vog whenever [he] could” but did not limit
    his physical activity.
    Van Ness had a follow-up visit with Dr. Tom on January
    28, 2006.    Dr. Tom’s clinical notes indicated that Van Ness’s
    symptoms of coughing, chest congestion, shortness of breath, and
    wheezing, had “never completely gone away from [the] 12/23/05
    -8-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    visit.”   Dr. Tom also made note of the possibility of “vog
    contributing” and “vog on Maui.”
    On March 4, 2006, Van Ness saw Dr. Sweet, his treating
    physician for his respiratory condition.         Van Ness was still
    experiencing shortness of breath and wheezing.          Dr. Sweet also
    noted that Van Ness had taken a trip to Pennsylvania and “[w]hile
    in Philadelphia he was on prednisone.        His wheezing and
    [shortness of breath] essentially resolved.          [Van Ness] states as
    soon as he returned to Maui he started to have wheezing and
    [shortness of breath].”
    On March 10, and 23, 2006, Dr. Tom wrote two notes,
    addressed “To Whom It May Concern,” stating that Van Ness had an
    asthma condition which was exacerbated by vog.          Dr. Tom wrote
    that Van Ness’s symptoms had worsened since moving to Maui due to
    the higher vog exposure there.       Dr. Tom recommended that Van Ness
    be transferred to O#ahu due to his condition.
    On March 23, 2006, the DOE approved Van Ness’s request
    for a “hardship transfer from Maui District to Oahu District due
    to medical reasons.”     However, Van Ness was not immediately
    transferred.
    On May 2, 2006, Van Ness was hospitalized at Queen’s
    Medical Center (QMC) on O#ahu for surgery on a hernia in his
    diaphragm.   Van Ness testified that the x-ray that Dr. Tom
    performed of Van Ness’s diaphragm in December 2005 had identified
    a “hole in the diaphragm . . . separating the abdomen from the
    lungs.”   He testified that “later it was found that because of
    -9-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    all the coughing and wheezing, . . . the tear had gotten a lot
    larger[.]”
    After surgery, Van Ness testified that he experienced
    various complications, including “post-operative pneumonia, post-
    operative multi-system organ failure, life threatening pneumonia,
    advanced respiratory distress syndrome, renal failure,
    gastrointestinal bleeding, tracheostomy and gangrene.”            The
    gangrene “led to amputation of the terminal digits of his first
    and fifth fingers on the right.”         Van Ness testified that Paul
    Morris, M.D. (Dr. Morris), Van Ness’s treating physician at QMC,
    told him that his body would not have been as physically weak
    post-operation if the DOE had transferred him to O#ahu in March
    2006 when his hardship transfer was approved by the DOE.
    Van Ness was discharged from QMC on June 9, 2006.             On
    July 25, 2006, Van Ness returned to work at Lahainaluna.
    Van Ness was transferred to O#ahu in November 2006.
    Following the transfer, he continued to have respiratory
    difficulties as his body recuperated from surgery.           On June 16,
    2007, Dr. Tom restricted Van Ness from “walking too far because
    that just kept [Van Ness] in a situation of overworking [his]
    lungs in the recovery period.”
    B.
    On September 20, 2007, Van Ness filed a workers’
    compensation claim with the Director, stating that “on or about”
    December 23, 2005, he was exposed to vog during the course of his
    employment at Lahainaluna, resulting in the “exacerbation of
    -10-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    [his] asthma, bronchitis, [and] difficulty breathing.”            He stated
    that he had given his employer notice of injury through Joanne
    Dennis, Lahainaluna’s Vice Principal.
    On October 12, 2007, the DOE filed a report denying
    liability for Van Ness’s claimed injury “pending further
    evaluation.”
    On October 19, 2007, Vice Principal Dennis wrote a
    letter confirming that prior to December 23, 2005, she had, on
    several occasions, discussed with Van Ness his difficulties with
    breathing and asthma that he experienced while working at
    Lahainaluna.    She also verified that “[w]e experienced some
    unusually severe vog-polluted days during the weeks preceding
    that winter break.”     “On some days the atmosphere was so heavy
    with vog that we could barely see Lahaina town from Lahainaluna
    High School.”    She noted that “the vog was even worse” in Kihei,
    where Van Ness lived.     Vice Principal Dennis also “experienced
    intense headaches during those ‘voggy’ days,” even though she did
    not have asthma.
    Van Ness also testified that he had discussed his
    medical condition with Vice Principal Lynn Kaholohala prior to
    December 23, 2005.
    C.
    Upon the DOE’s request, the Director issued an order on
    January 11, 2008, requiring Van Ness to submit to an Independent
    -11-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Medical Examination (IME) by Ajit S. Arora, M.D. (Dr. Arora).2
    The IME was conducted on January 25, 2008, and consisted of an
    “extended interview and examination.”3 No medical records were
    available for Dr. Arora’s review at the time.           Dr. Arora
    submitted his report on February 5, 2008.
    As an initial matter, Dr. Arora noted that “[t]he claim
    apparently is based on the assumption that since exposure to vog
    occurred also at the school, it is a work related exacerbation of
    asthma.   The legal implications of this are not clear to me
    because vog is not a factor that is associated with school
    2
    The DOE asked Dr. Arora to review Van Ness’s medical records and
    to conduct a physical examination in order to address: (1) Van Ness’s relevant
    medical history; (2) whether Van Ness suffered “an industrial injury” as a
    result of exposure to vog on December 23, 2005; (3) whether the “alleged
    condition was due in whole or in part to the nature of [Van Ness’s] employment
    with the DOE,” or some other pre-existing cause; (4) whether the alleged
    condition or injury was “temporary in nature”; (5) if the injury is not
    temporary in nature, whether Van Ness is “expected to have permanent
    impairment resulting solely from an alleged industrial injury of 12/23/05”;
    and 5) whether there are any further issues or considerations regarding the
    alleged injury.
    3
    Dr. Arora noted that Van Ness, upon advice of counsel, refused to
    submit to blood work or to testing with an electrocardiogram to assess organ
    function.
    On March 31, 2010, the DOE filed a motion for an order suspending
    Van Ness’s right to claim compensation for failure to comply with HRS § 386-
    79, based on Van Ness’s refusal to have tests done during the IME.
    Furthermore, the DOE alleged that Van Ness’s counsel “revoked medical
    authorizations” and withheld certain medical records.
    On June 23, 2010, the LIRAB denied the DOE’s requested order. In
    the DOE’s June 3, 2010 post-hearing trial memorandum filed with the LIRAB, the
    DOE continued to argue that Van Ness’s right to seek compensation should be
    suspended because of his failure to participate in tests during the IME and
    his continued withholding of medical records. The LIRAB concluded that it did
    not need to reach the DOE’s argument regarding the suspension of Van Ness’s
    rights to claim workers’ compensation benefits.
    HRS § 386-79 (1993) provides that “[a]fter an injury and during
    the period of disability, the employee, whenever ordered by the [Director],
    shall submit oneself to examination . . . by a duly qualified physician or
    surgeon designated and paid by the employer.” The statute further states that
    “[i]f an employee refuses to submit oneself to, or in any way obstructs, such
    examination the employee’s right to claim compensation for the work injury
    shall be suspended until the refusal or obstruction ceases and no compensation
    shall be payable for the period during which the refusal or obstruction
    continues.” 
    Id. -12- ***

    uniquely.”
    The majority of Dr. Arora’s report reiterated Van
    Ness’s medical history and exposure to vog at Lahainaluna,
    consistent with Van Ness’s testimony at the LIRAB hearing.             Dr.
    Arora stated that “the issues are quite complex.”           Because Dr.
    Arora did not have access to Van Ness’s medical records, he
    concluded that “it [would] be unwise to address the [DOE’s]
    referral questions” until he had access to the relevant records.
    On February 14, 2008, Van Ness was seen by David A. Mathison,
    M.D. (Dr. Mathison), for a consultation regarding “asthma,
    allergies, [and] vog effect on lungs.”         Dr. Mathison prepared a
    consultation report based on his interview with Van Ness and his
    wife, a physical examination of Van Ness, and Van Ness’s medical
    records provided by Dr. Sweet dating back to 1991, which included
    a summary of Van Ness’s hospitalization at QMC in May 2006.
    Dr. Mathison first discussed Van Ness’s aggravated
    asthma and noted that after several months on Maui “during a 40-
    day spell of rainy weather with vog (moisture, pollutants
    including volcanic smoke/ash) exposure from about November 2005
    and continuing into the spring of 2006, [Van Ness] had serious
    flare of asthmatic symptoms with harsh paroxysms of cough, chest
    tightness, shortness of breath, and wheeziness[.]”           At that time
    Van Ness’s symptoms were “only partially controlled with
    medications for asthma/bronchitis including Advair, Singulair,
    and albuterol.”
    -13-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Dr. Mathison wrote that Van Ness’s symptoms were
    complicated by “hernia of the right diaphragm, and urgent surgery
    was performed at the Queens Medical Center on May 2, 2006.”             Dr.
    Mathison also noted the various post-surgery complications Van
    Ness experienced.    He wrote that after being discharged from the
    hospital, Van Ness had “improved respiratory symptoms, he was
    able to return to Maui and work there through the remainder of
    2006.”
    Dr. Mathison noted that since moving back to O#ahu, Van
    Ness “has been relatively free of respiratory symptoms.            He . . .
    rarely has had need for albuterol and has not regularly taken the
    Advair.”
    Dr. Mathison noted that throughout the years, Van
    Ness’s “allergic diathesis has largely been controlled with
    avoidances and the several-year course of immunotherapy during
    the early 90s.    However, he has had significant asthma
    exacerbations with exposures to volcanic smoke (high in sulfur
    dioxide) and ash including that carried by meteorologic[al]
    conditions holding the pollutant[] in moist air over Maui.”             Dr.
    Mathison also found that at the time of the consultation, Van
    Ness’s condition had “improved coincident to his residence in
    Oahu, though he continues to . . . recover[] from complications
    of respiratory disease-surgery from near 2 years ago.”
    In conclusion, Dr. Mathison diagnosed Van Ness with
    “[m]ild persistent asthma with history of exacerbations with
    exposures to volcanic smoke-ash-pollution.”
    -14-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Dr. Mathison recommended that Van Ness “continue the
    regimen of avoidances and medications as prescribed by Dr. Sweet
    in an attempt to optimally control the allergic-asthmatic
    disorders.”    Dr. Mathison wrote, “Of particular concern is the
    risk for serious and potentially fatal asthma exacerbation with
    exposure to volcanic products, a well-recognized risk factor for
    asthmatic patients.”      (Emphasis added).      He concluded that Van
    Ness “can be considered to be disabled by virtue of his asthmatic
    tendency and susceptibility to the volcanic pollutant effects
    and, in accordance with the American Disabilities Act, it
    behooves his employer not to place him at risk of asthmatic
    exacerbations by assignments to areas likely to have volcanic
    exposure-pollution.”      (Emphasis added).
    D.
    The Director’s hearing on Van Ness’s claim was held on
    March 13, 2008.4 On April 21, 2008, the Director issued a
    decision denying Van Ness’s workers’ compensation claim.             The
    Director stated that “[a]fter a review of the evidence presented
    at the hearing, the Director is not convinced that claimant’s
    injury arose out of and in the course of employment.”             The
    Director found that “[Van Ness’s] exposure to vog aggravated his
    long standing asthma condition.”          However, “[t]he vog was present
    on the entire island of Maui and not only at claimant’s place of
    employment.”    The Director found that “it was claimant’s exposure

    The transcript for the March 13, 2008 hearing was not made part of
    the record on appeal.
    -15-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    to vog on the island of Maui that aggravated his asthma
    condition,” and there was “insufficient evidence” to support Van
    Ness’s “claim that his exposure to vog at only Lahainaluna School
    was so overwhelming that [Van Ness’s] exposure to vog occurred at
    this place of employment only[.]”          The Director therefore did not
    “find a nexus between the claimant’s employment and his injury of
    12/23/2005.”
    The Director concluded: “[T]he claimant’s respiratory
    problem and aggravation of his asthma condition was not work
    related.     The Director credits the report of Dr. Arora and the
    employer’s position.”
    II.   APPEAL TO LIRAB
    On May 2, 2008, Van Ness timely filed an appeal from
    the Director’s Decision with LIRAB, pursuant to HRS § 386-87.5
    A.
    On April 10, 2009, Dr. Arora issued a supplemental
    report as a follow-up to his initial evaluation of February 5,
    2008.     The report reviewed records from Dr. Tom from 1994 through
    2007, diagnostic reports from the same time period, records from
    the California hospital where Van Ness was admitted in 2004, and
    hospital records from January 2005 through October 2006.
    Dr. Arora wrote that Dr. Tom’s records from Van Ness’s December
    23, 2005 visit noted that Van Ness had experienced a cough for
    5
    HRS § 386-87(a) (1993) provides in relevant part: “A decision of
    the director shall be final and conclusive between the parties, . . . unless
    within twenty days after a copy has been sent to each party, either party
    appeals therefrom to the appellate board by filing a written notice of appeal
    with the appellate board or the department.”
    -16-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    only five days, had difficulty breathing, and requested a refill
    of his albuterol inhaler.      According to Dr. Arora, Dr. Tom did
    not make any note of the vog as a contributory factor.
    Additionally, Dr. Arora found that Van Ness had seen
    Dr. Tom on December 2, 2005 for a regular checkup and laboratory
    work-up, and did not report any problem with breathing at that
    time.
    In Dr. Arora’s opinion, it was “impossible to
    determine” if the reported worsening of Van Ness’s asthma
    symptoms in March 2006 was caused by the vog or by the
    diaphragmatic hernia that worsened around the same time.
    Dr. Arora stated that he had “not had the opportunity to review
    the records from Dr. Sweet to determine if objectively there was
    any change in [Van Ness’s] pulmonary status between December 2005
    and March 2006 compared to his previous baseline.”           Nevertheless,
    Dr. Arora indicated, “I doubt that to be the case.”           He
    explained, “Asthma exacerbation can occur in association with
    irritant exposure.    However, it is a temporary worsening of the
    symptoms with recovery to baseline.        It does not constitute
    aggravation of the condition.”
    Dr. Arora concluded that Van Ness’s “history is
    compatible with mild exacerbation of his asthma while in Maui
    because of vog conditions.”      Dr. Arora also concluded that the
    exacerbation of asthma “has no relationship to his employment
    with the department of education,” and “[s]uch exacerbation was
    temporary and reversible and did not cause any permanent
    -17-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    aggravation of his condition.”        Dr. Arora’s opinion was that
    “there was no occupational injury that occurred in [Van Ness] as
    a result of employment with [the DOE].”
    B.
    On July 1, 2009, the LIRAB issued a Pretrial Order,
    providing that “[t]he sole issue to be determined is whether
    Claimant sustained a personal injury to his respiratory system,
    on December 23, 2005, arising out of and in the course of
    employment.”6
    The LIRAB hearing on the case was held on April 6,
    2010.    Van Ness was the only testifying witness at the hearing,
    and testified as to his asthmatic condition and his experience
    working at Lahainaluna, as summarized above.
    An air quality advisory that was posted on the State of
    Hawai#i government’s website on July 29, 2008 was stipulated into
    evidence.    The advisory stated that the State Department of
    Health and Hawai#i County Civil Defense had reported “that recent
    activity at the Kilauea volcano has resulted in some temporary
    increased levels” of sulfur dioxide and particulates.             The
    advisory provided that the Department of Health “advises that
    exposure to such elevated levels of sulfur dioxide can pose an
    immediate health threat to people who have asthma and other
    respiratory conditions.”       (Emphasis added).      The advisory further
    stated that people in “sensitive groups such as those with asthma
    . . . can be particularly vulnerable” and that “people reacting
    6
    The Director’s case file was made a part of the LIRAB’s record.
    -18-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    to volcanic emissions” should “take protective measures such as
    staying indoors with the windows closed or relocating to a safe
    area.”   The advisory cautioned that people should “avoid physical
    activity (especially outdoors) such as brisk walking or
    exercise.”
    In addition, an undated document entitled “Health
    Effects,” prepared by the Office of the Governor, was also
    entered into evidence.     The document explained that sulfur
    dioxide is an “irritant gas” that is “a major component of vog.”
    Sulfur dioxide “is usually removed by the nasal passages,” and
    “[m]oderate activity levels that trigger mouth breathing (such as
    a brisk walk) are needed for [sulfur dioxide] to cause health
    problems.”
    The document further stated that “[p]eople with pre-
    existing respiratory conditions are more prone to adverse effects
    of vog which may include: headaches, breathing difficulties,
    increased susceptibility to respiratory ailments, watery eyes,
    and sore throat.”    Additionally, “[p]eople with asthma who are
    physically active outdoors are most likely to experience the
    health effects of [sulfur dioxide].        The main effect, even with a
    short exposure, is a narrowing of the airways (called
    bronchoconstriction).     This may cause wheezing, chest tightness,
    and shortness of breath.”      (Emphasis added).
    Both the air quality advisory and the “Health Effects”
    notice provided that “[t]he long-term health effects of vog are
    unknown.”
    -19-

    C.
    The LIRAB ordered that the parties submit post-trial
    memoranda in lieu of closing arguments.
    1.
    In his Post Hearing Memorandum, Van Ness argued that he
    “suffered an aggravation of his asthmatic condition due to having
    to do strenuous work and breathe outdoor air during a period of
    high vog concentrations.”      He contended that the DOE failed to
    provide substantial evidence to overcome the presumption of
    compensability for his workers’ compensation claim.           Van Ness
    argued that the aggravation of his asthma met the test for
    compensability under Flor v. Holguin, 94 Hawai#i 70, 81, 
    9 P.3d 382
    , 393 (2000), which held that an injury by disease is
    compensable if the disease (1) is caused by conditions that are
    characteristic of or peculiar to the particular trade,
    occupation, or employment, (2) results from the employee’s actual
    exposure to such working conditions, and (3) is due to causes in
    excess of the ordinary hazards of employment in general.
    The DOE countered that Van Ness failed to establish a
    nexus between his employment and the alleged injury of vog-
    related asthma.    The DOE argued that there was no causal
    connection between Van Ness’s employment and his injury because
    Van Ness was not required to be at work on the alleged date of
    injury and his medical records indicated that his respiratory
    problems were related to his preexisting health condition.
    -20-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Additionally, the DOE argued that there was no evidence
    that the vog conditions experienced by Van Ness at work were
    greater than that experienced by the general population.            The DOE
    also contended that any aggravation of Van Ness’s asthmatic
    condition was temporary in nature as demonstrated by his improved
    health when he was transferred to O#ahu.
    2.
    On September 20, 2011, the LIRAB issued its Decision
    and Order, which included its Findings of Fact (FOF) and
    Conclusions of Law (COL).
    With respect to Van Ness’s medical records, the LIRAB
    found that: 1) on March 23, 2007, Dr. Tom “concluded that [Van
    Ness] suffered from asthma exacerbated by vog while he was on
    Maui” and recommended that Van Ness move to O#ahu; 2) on February
    14, 2008, Dr. Mathison diagnosed Van Ness with “mild persistent
    asthma with history of exacerbations with exposures to volcanic
    smoke-ash-pollution”; and 3) Dr. Arora’s opinion in his
    supplemental report was that “Claimant’s history was compatible
    with mild exacerbation of his asthma because of vog conditions.”
    The LIRAB entered findings reiterating Van Ness’s
    testimony about Lahainaluna’s campus, the vog at work, and his
    pre-existing asthma condition.       However, the LIRAB found that Van
    Ness faced the same “hazard from vog exposure” at work as the
    general public, and the DOE had presented substantial evidence to
    overcome the presumption of compensability:
    9. The Board finds that Claimant’s work or work environment
    posed no greater vog exposure than that posed to the general
    -21-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    public. The hazard from vog exposure Claimant faced while
    on the campus of Lahainaluna School was no greater hazard or
    risk than that faced by others off of the campus of
    Lahainaluna School.
    10. The Board has applied the presumption of compensability
    and finds that Employer has presented substantial evidence
    to overcome said presumption.
    (Emphases added).
    The LIRAB thus concluded that Van Ness “did not sustain
    a personal injury to his respiratory system, on December 23,
    2005, arising out of and in the course of employment.”            The LIRAB
    explained that Van Ness “was not at work or even on Maui on
    December 23, 2005.”
    “However, inasmuch as Claimant identified his date of
    injury as ‘on or about’ December 23, 2005,” the LIRAB also
    concluded that it was “not persuaded by” Van Ness’s argument that
    “his asthma was a compensable disease caused by conditions
    peculiar to his particular employment.”         In this regard, the
    LIRAB concluded that “exposure to vog was not accentuated or made
    worse by the nature and conditions of Claimant’s employment,”
    based on the following reasoning:
    Claimant was a technology coordinator. His risk of exposure
    to vog was walking outdoors and being in some buildings that
    were not air-conditioned. These exposures are no greater
    than that of the general public. The nature and conditions
    of his employment did not accentuate the exposure. Rather,
    the vog was in the air, and the general public breathed the
    same air.
    (Emphasis added).
    The LIRAB also rejected Van Ness’s claim that, “but for
    work, he would otherwise have been in a filtered environment at
    his home.”   The LIRAB reasoned that “the relevant comparison is
    -22-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    made to the general public’s exposure, not Claimant’s alleged
    comparatively hermetic and sterile home environment.”
    Based on the foregoing, the LIRAB concluded that it was
    unnecessary to address the DOE’s argument that Van Ness’s “right
    to claim workers’ compensation benefits be suspended because of
    his refusal to cooperate by undergoing the tests requested by Dr.
    Arora.”7
    Therefore, the LIRAB affirmed the Director’s decision
    to deny compensation.
    III.   APPEAL TO ICA
    On October 20, 2011, Van Ness timely filed a Notice of
    Appeal to the ICA.8
    A.
    Van Ness raised three points of error on appeal to the
    ICA, alleging that the LIRAB erred 1) in entering FOF 9 that his
    vog exposure at work posed no greater vog exposure or greater
    hazard or risk than that faced by the general public; 2) by
    concluding that he did not sustain a personal injury to his
    respiratory system on December 23, 2005, arising out of and in
    the course of employment; and 3) by concluding that his exposure
    to vog was not made worse by the nature and conditions of his
    employment because the general public breathed the same air.
    7
    See supra note 3.
    8
    HRS § 386-88 (Supp. 2011) provides in relevant part: “The decision
    or order of the appellate board shall be final and conclusive, . . . unless
    within thirty days after mailing of a certified copy of the decision or order,
    the director or any other party appeals to the intermediate appellate court, .
    . . by filing a written notice of appeal with the appellate board.”
    -23-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Van Ness reiterated that the aggravation of his asthma
    condition was compensable as an injury by disease under the Flor
    test.   With respect to the first Flor factor, he argued that his
    preexisting asthma condition should be considered along with the
    unique nature of his work at Lahainaluna, as compared with the
    same position at other schools.       Second, Van Ness argued that his
    work required actual exposure to vog, as was found by the LIRAB
    in FOF 9, and the evidence demonstrated that exposure to vog
    adversely affected him and exacerbated his asthma.           Third, Van
    Ness contended that the LIRAB erred in comparing his vog exposure
    to that of the general public, as the general public was not
    exposed to the vog conditions while being “required to do
    strenuous work outdoors.”      The real issue was that “Claimant’s
    job conditions exposed him to a positional or actual risk which
    resulted in his injury.”      In this case, the LIRAB’s own findings
    demonstrated that his asthma was exacerbated by vog.
    In response, the DOE maintained that Van Ness’s claim
    was non-compensable based on the evidence that Van Ness was
    exposed to the same air and vog at work as all other persons on
    Maui.   Additionally, the DOE argued that “[a]lthough the medical
    experts opined that vog exacerbated Claimant’s asthma, none of
    them opined that Claimant’s asthma was exacerbated by his
    employment.”
    The DOE further contended that while it was unclear
    whether Van Ness was pursuing his claim as an injury by accident
    or injury by disease, the LIRAB accurately concluded that Van
    -24-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Ness’s injury was not compensable under either alternative.              With
    respect to an injury by accident, the DOE argued that the LIRAB
    correctly found that there was no nexus between the alleged
    injury and Van Ness’s employment, as Van Ness was not physically
    present at work or on Maui on the alleged date of injury.              In
    regard to an injury by disease claim under Flor, the DOE
    maintained that there was “no evidence that [Van Ness’s] asthma
    is characteristic of his occupation as a technology coordinator.”
    The DOE acknowledged that Van Ness “may meet” the second Flor
    requirement, as there was evidence that “Claimant’s presence at
    Lahainaluna School, just as his presence anywhere on the island
    of Maui, exacerbated his asthma due to the presence of vog.”                 As
    to the third Flor condition, the DOE maintained that there was
    “no evidence that the aggravation of Claimant’s asthma is due to
    causes in excess of the ordinary hazards or employment in
    general,” as the vog affected the entire island. Therefore, the
    LIRAB’s FOF 9 and FOF 10 were correct.9
    Van Ness responded that his claim was based on an
    injury by disease under the Flor test.          He also argued that the
    DOE misconstrued Flor as requiring “all technology coordinators .
    9
    Relatedly, the DOE argued that Van Ness failed to challenge FOF 10
    as a point of error and that any arguments regarding FOF 10 should therefore
    be disregarded.
    Van Ness responded that his argument should not be disregarded, as
    FOF 10 was thoroughly discussed as a point of error in the body of his Opening
    Brief. [RB at 8] Van Ness argued that FOF 10 was clearly erroneous because
    the DOE did not adduce substantial evidence to overcome the presumption of
    compensability.
    The ICA found that although Van Ness had not raised FOF 10 as a
    point of error, he had challenged FOF 10 in the argument section of his
    Opening Brief and provided the necessary information to assist the ICA in
    identifying his argument. Van Ness v. State, No. CAAP-11-0000775, 
    2012 WL 6115601
    , at *2 (Haw. App. Dec. 10, 2012) (mem.).
    -25-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    . . to have something in their work that causes asthma.”            Rather,
    the correct analysis was to determine whether a condition,
    characteristic to Van Ness’s particular job as a technology
    coordinator at Lahainaluna, caused the exacerbation of his
    asthma.
    B.
    The ICA applied the Flor test for providing coverage
    for injuries caused by an “occupational disease.”           Van Ness v.
    State, No. CAAP-11-0000775, 
    2012 WL 6115601
    , at *4 (Haw. App.
    Dec. 10, 2012) (mem.).     Characterizing Van Ness’s claim as a
    claim that the exacerbation of his asthma resulted from work-
    related vog exposure, the ICA found that the second condition of
    the Flor test was met because it was “undisputed that Van Ness
    faced actual exposure to vog in his employment[.]”           
    Id. However, the
    ICA concluded that Van Ness’s claim did not constitute a
    “compensable occupational disease because the DOE produced
    substantial evidence” that the first (disease caused by
    conditions characteristic of employment) and third (disease due
    to causes in excess of ordinary hazards of employment) conditions
    of Flor were not met.     
    Id. Citing Flor,
    the ICA applied the following standard for
    compensable occupational diseases:
    [A]n occupational disease requires “a recognizable link
    between the disease and some distinctive feature of the
    claimant’s job, common to all jobs of that sort.” An
    occupational disease cannot be “an ordinary disease of life
    to which general public was equally exposed outside of that
    employment,” and the disease must “have incidence
    substantially higher in that occupation than in usual
    occupations or, in case of ordinary disease of life, in
    general population.” In other words, the Flor test requires
    -26-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    that “the employer’s working conditions produced the ailment
    as a natural incident of the employee’s occupation in such a
    manner as to attach a hazard distinct from and greater than
    the hazard attending employment in general.”
    
    Id. (citations omitted)
    (emphasis added).
    The ICA found that Van Ness did not meet this test,
    emphasizing the requirement that the feature causing the disease
    be “common to all jobs of that sort.”        
    Id. The ICA
    reasoned that
    “Van Ness’s occupation was as a technology coordinator, and his
    primary duties were maintaining and repairing technology
    equipment.”    
    Id. at *5.
       “This work, in and of itself, could not
    have exacerbated his asthma and Van Ness does not contend that it
    does.”   
    Id. Thus, the
    ICA concluded, “his disease was produced
    not by ‘natural incident’ or ‘distinctive feature of the
    claimant’s job, common to all jobs of that sort,’ but rather by
    his exposure to vog.”     
    Id. (citation omitted)
    (emphasis added).
    The ICA continued, “Vog exposure itself cannot be considered a
    condition characteristic of or peculiar to Van Ness’s employment,
    however, because it is undisputed that vog affected the entire
    island of Maui at the time.”        
    Id. The ICA
    held that the LIRAB’s FOF 9, finding that Van
    Ness’s work or work environment posed no greater vog exposure
    than that posed to the general public, was supported by
    substantial evidence rebutting the presumption that Van Ness’s
    injury was work-related.      
    Id. In this
    regard, the ICA cited the
    medical reports, finding that the “reports all concluded the Maui
    vog exacerbated Van Ness’s asthma, but nothing in those reports
    noted any relationship between the exacerbation and Van Ness’s
    -27-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    employment.”   
    Id. (emphases added).
          Dr. Tom’s recommendation
    that Van Ness transfer to O#ahu rather than to another position
    on Maui demonstrated that Van Ness’s “condition was not peculiar
    to his employment at Lahainaluna.”        
    Id. Additionally, the
    ICA
    noted the vice principal’s statement that she also experienced
    adverse effects of vog and that the vog was heavier in other
    parts of Maui.     
    Id. Thus, the
    ICA concluded that Van Ness “faced
    a risk no different and no greater than that faced by any member
    of the general public or in another field of work who spent time
    outdoors.”   
    Id. The ICA
    further emphasized Dr. Arora’s conclusion in
    his supplemental report that Van Ness’s exacerbated asthma had
    “no relationship to his employment with the DOE.”           
    Id. (brackets and
    quotation marks omitted).       The ICA noted that Dr. Arora
    reviewed “extensive medical records,” which “indicate Van Ness
    had a complex medical history and numerous health issues,” and
    Dr. Arora “identified a diaphragmatic hernia as a possible cause
    or contributing factor of Van Ness’s exacerbated asthma.”             
    Id. According to
    the ICA, “Dr. Arora’s reports were sufficiently
    specific and credible to constitute substantial evidence, and
    given the complexity of Van Ness’s medical history, it was
    reasonable for the LIRAB to conclude Van Ness’s condition was
    unrelated to his work.”     
    Id. at *6.
    In addition, the ICA found that “[o]ther than Van
    Ness’s own testimony about his work environment and his duties,
    there is no other evidence in the record suggesting that vog
    -28-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    exposure was a hazard peculiar to his employment or in excess of
    the hazards of employment in general.”         
    Id. The ICA
    therefore concluded that the LIRAB’s decision
    was not clearly erroneous and affirmed the decision.            
    Id. IV. APPLICATION
    A.
    On April 1, 2013, Van Ness timely filed the Application
    and presented the following questions for review:
    A. Is the contraction of a disease compensable under HRS §
    386-3 although there is no historical association of that
    disease with that particular line of work?
    B. Are “ordinary diseases of life” compensable under HRS §
    386-3?
    C. Should a test similar to the “unitary test” of Royal
    State National Insurance Company v. Labor & Industrial
    Relations Appeal Board, 
    53 Haw. 32
    , 
    487 P.2d 278
    (1971),
    be applied to “diseases” under HRS § 386-3?
    In his Application, Van Ness argued that Flor did not
    limit compensable diseases to those associated with particular
    trades.   Rather, under Flor, “causation could be . . . peculiar
    to the particular ‘occupation, or employment’.”           Thus, the ICA
    erred in holding that his “claim failed because all technology
    coordinator positions do not face asthma exacerbation.”
    Van Ness proposed that “[a] test similar to the unitary test of
    compensability for injury by ‘accidents’ should also apply to
    injury by ‘disease,’ that is, the requirement of HRS § 386-3 is
    simply that the disease be proximately caused by or result from
    the nature of employment.”        At oral argument, counsel for Van
    Ness maintained that the Flor test was met, but also extended
    -29-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    this argument by asking the court to reexamine or overrule the

    determine the compensability of injuries by disease under HRS §
    386-3(a).    MP3: Oral Argument, Hawai#i Supreme Court, at 0:03:00,

    In response, the DOE maintained that Van Ness, “at
    most, met one of the three criteria established by Flor” but that
    Flor “requires that all three criteria must exist for an
    occupational disease claim to be compensable.”
    Alternatively, the DOE argued that the ICA’s ruling
    should be upheld even if it misapplied the Flor test because Van
    Ness’s injury also did not meet the requirements for
    compensability of an injury by accident.         The DOE contended that
    although “both the Board and ICA decided the case based on the
    merits of an occupational disease claim, both should have decided
    the claim as an injury by accident claim.”         The DOE emphasized
    that the LIRAB’s pretrial order identifies the issue as whether
    Van Ness “sustained a personal injury to his respiratory system .
    . . arising out of and in the course of employment,” which
    “connotes an injury by accident claim.”         However, at oral
    argument, counsel for the DOE stated that although the LIRAB
    framed the issue as an injury by accident, it was not necessarily
    the DOE’s position that the LIRAB should have decided Van Ness’s
    -30-

    claim as an injury by accident rather than an injury by disease.

    V.   STANDARDS OF REVIEW
    A. Board decisions
    Appellate review of the LIRAB's decision is governed by
    HRS § 91–14(g) (1993), which provides that:
    Upon review of the record the court may affirm the decision
    of the agency or remand the case with instructions for
    further proceedings; or it may reverse or modify the
    decision and order if the substantial rights of the
    petitioners may have been prejudiced because the
    administrative findings, conclusions, decisions, or orders
    are:
    (1) In violation of constitutional or statutory provisions;
    or(2) In excess of the statutory authority or jurisdiction
    of the agency; or
    (3) Made upon unlawful procedure; or
    (4) Affected by other error of law; or
    (5) Clearly erroneous in view of the reliable, probative,
    and substantial evidence on the whole record; or
    (6) Arbitrary, or capricious, or characterized by abuse of
    discretion or clearly unwarranted exercise of discretion.

    The LIRAB’s conclusions of law are reviewed de novo,
    under the right/wrong standard.       
    Id. Its findings
    of fact “are
    reviewable under the clearly erroneous standard to determine if
    the agency decision was clearly erroneous in view of reliable,
    probative, and substantial evidence on the whole record.”

    B.   Statutory interpretation
    “The interpretation of a statute is a question of law
    which this court reviews de novo.          When construing a statute, our
    foremost obligation is to ascertain and give effect to the
    intention of the legislature, which is to be obtained primarily
    from the language contained in the statute itself.”           Tauese, 113
    Hawai#i at 
    26, 147 P.3d at 810

    VI.   DISCUSSION
    HRS § 386-3(a) (Supp. 2005) provides, “If an employee
    suffers personal injury either by accident arising out of and in
    the course of the employment or by disease proximately caused by
    or resulting from the nature of the employment, the employee’s
    employer or the special compensation fund shall pay compensation
    to the employee or the employee’s dependents[.]”
    Pursuant to HRS § 386-85 (1993), for any workers’
    compensation claim, “it shall be presumed, in the absence of
    substantial evidence to the contrary . . . [t]hat the claim is
    for a covered work injury.”      “In workmen’s compensation cases,
    the employer carries a heavy burden.”         Lawhead v. United Air
    Lines, 
    59 Haw. 551
    , 559, 
    584 P.2d 119
    , 124 (1978).           The
    presumption imposed by HRS § 386-85 “is not a mere procedural
    device that disappears upon the introduction of contrary
    evidence.”   Akamine v. Hawaiian Packing & Crating Co., 
    53 Haw. 406
    , 408, 
    495 P.2d 1164
    , 1166 (1972).         Rather, “it imposes upon
    the employer the burden of going forward with the evidence and
    -32-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    the burden of persuasion.”      
    Id. The presumption
    is rebutted
    “only by substantial evidence that [the injury] is unrelated to
    the employment.”    
    Id. “The term
    ‘substantial evidence’ signifies a high
    quantum of evidence which, at the minimum, must be ‘relevant and
    credible evidence of a quality and quantity sufficient to justify
    a conclusion by a reasonable [person] that an injury or death is
    not work-connected.’”     Flor, 94 Hawai#i at 
    79, 9 P.3d at 391
    (quoting 
    Akamine, 53 Haw. at 408
    , 495 P.2d at 1166) (emphasis
    added).   “If the employer fails to adduce substantial evidence to
    the contrary, the presumption mandates that the claimant must
    prevail.”   
    Akamine, 53 Haw. at 409
    , 495 P.2d at 1166.
    The high burden placed on the employer is attributed to
    the purpose of the workers’ compensation law.          “[T]he legislature
    has decided that work injuries are among the costs of production
    which industry is required to bear[.]”         
    Id. “Workmen’s compensation
    laws were enacted as a humanitarian measure, to
    create legal liability without relation to fault.           They represent
    a socially enforced bargain: the employee giving up his right to
    recover common law damages from the employer in exchange for the
    certainty of a statutory award for all work-connected injuries.”
    Evanson v. Univ. of Haw., 
    52 Haw. 595
    , 598, 
    483 P.2d 187
    , 190
    (1971).
    Accordingly, “[t]his court has consistently construed §
    386-85 liberally in accordance with the humanitarian purposes of
    workmen’s compensation.”      
    Lawhead, 59 Haw. at 559
    , 584 P.2d at
    -33-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    124.   Thus, “[i]n addition to the presumption of compensability,
    the broad humanitarian purpose of the workers’ compensation
    statute read as a whole requires that all reasonable doubts be
    resolved in favor of the claimant[.]”         
    Id. at 560,
    584 P.2d at
    125 (quotation marks and citations omitted) (emphasis added).
    See 
    Akamine, 53 Haw. at 409
    , 495 P.2d at 1166 (“if there is
    reasonable doubt as to whether an injury is work-connected, the
    humanitarian nature of the statute demands that doubt be resolved
    in favor of the claimant”).
    A.
    In this case, Van Ness alleged that the aggravation of
    his asthma resulting from his exposure to vog at Lahainaluna was
    a compensable injury by disease.          This court has interpreted HRS
    § 386-3 broadly to “reflect[] the policy of the Workmen’s
    Compensation Law that an employee should be indemnified for all
    infirmities resulting from his employment.”           Royal State Nat’l
    Ins. Co. v. Labor & Indus. Relations Appeal Bd., 
    53 Haw. 32
    , 37,
    
    487 P.2d 278
    , 281 (1971) (emphasis added) (holding that “psychic
    injuries arising out of the employment relationship” are
    compensable under the statute).        The parties have not contested
    that the aggravation of Van Ness’s asthma would constitute a
    compensable injury if it was sufficiently connected to his
    employment.10
    10
    In the context of workers’ compensation, “[t]he term ‘disease’
    [has been] construed in its broadest dictionary meaning of any ‘serious
    derangement of health’ or ‘disordered state of an organism or organ.’” A.
    Larson, Workers’ Compensation Law § 52.04[2] (2012) [hereinafter Larson’s].
    See Black’s Law Dictionary 535 (9th ed. 2009) (defining “disease” as a
    “deviation from the healthy and normal functioning of the body,” “[a]ny
    -34-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    The parties dispute whether the aggravation of Van
    Ness’s asthma was “proximately caused by or resulting from the
    nature of the employment.”       In this regard, the parties have
    focused on the applicability of the three-part test for
    occupational diseases established in Flor v. Holguin, 94 Hawai#i
    70, 
    9 P.3d 382
    (2000), recon. granted in part, 94 Hawai#i 92, 
    9 P.3d 404
    (2000).
    In Flor, the court held that “an employee’s injury
    caused by a disease is compensable as an ‘injury by disease,’
    pursuant to HRS § 386-3, when the disease (1) is caused by
    conditions that are characteristic of or peculiar to the
    particular trade, occupation, or employment, (2) results from the
    employee’s actual exposure to such working conditions, and (3) is
    due to causes in excess of the ordinary hazards of employment in
    general.”    94 Hawai#i at 
    81, 9 P.3d at 393
    (citations omitted).
    Applying this test, the ICA in this case found that although it
    was “undisputed that Van Ness faced actual exposure to vog in his
    employment, satisfying the second condition,” “Van Ness’s
    condition does not fall within the definition of a compensable
    occupational disease because the DOE produced substantial
    evidence that the first and third conditions of Flor were not
    met.”   
    2012 WL 6115601
    , at *4.        Similarly, the LIRAB rejected Van
    Ness’s argument that his asthma was a compensable disease,
    concluding that “[t]he nature and conditions of his employment
    disorder; any depraved condition”).
    -35-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    did not accentuate the exposure” to vog because “the vog was in
    the air, and the general public breathed the same air.”
    Inasmuch as the ICA and LIRAB considered whether vog
    exposure was a natural incident of Van Ness’s occupation as a
    technological coordinator, the analyses reflect a conflation of
    the injury by disease prong of HRS § 386-3(a).           The plain
    language of HRS § 386-3(a) provides for two distinct ways in
    which an “injury by disease” may be compensable under the
    statute: “If an employee suffers personal injury . . . by disease
    proximately caused by or resulting from the nature of the
    employment, the employee’s employer . . . shall pay compensation
    to the employee . . . .”       (Emphasis added).
    Revised Laws of Hawai#i (RLH) § 97-3 (1955), the
    counterpart to HRS § 386-3, provided that “[i]f a workman
    receives personal injury . . . by disease proximately caused by
    the employment, or resulting from the nature of the employment,
    his employer . . . shall pay compensation[.]”           The history of the
    statute thus demonstrates that disease proximately caused by
    employment and disease resulting from the nature of employment
    were intended to be distinct, although related, concepts.
    A close reading of Flor indicates that the three-part
    test articulated in that case is not applicable to situations in
    which the disease is alleged to be “proximately caused by”11 the
    11
    See Black’s Law Dictionary 250 (9th ed. 2009) (defining “proximate
    cause” as “[a] cause that is legally sufficient to result in liability”);
    Montalvo v. Lapez, 77 Hawai#i 282, 287 n.5, 
    884 P.2d 345
    , 350 n.5 (1994) (“For
    our purposes, the terms ‘legal cause’ and ‘proximate cause’ are
    synonymous[.]”).

    employment, rather than alleged to “result[] from the nature of
    the employment.”
    In Flor, the claimant filed a workers’ compensation
    claim upon being diagnosed with the hepatitis C virus after
    decades of working as a dental hygienist for numerous dentists
    and periodontists.    
    Id. at 74,
    9 P.3d at 386.        There was
    significant evidence demonstrating that the claimant “probably
    had acquired hepatitis C through work exposure to contaminated
    blood.”   
    Id. However, the
    re was “no test or procedure that could
    reliably isolate either the time of first infection with
    hepatitis C or the source of the infection,” and the claimant was
    “unable to recall, identify, or otherwise determine the date on
    which she contracted hepatitis C.”        
    Id. Given the
    multiple
    employers and lengthy time period involved, and the inability to
    isolate the event precipitating the disease, the court stated
    that it would analyze the claim as an “injury by disease,” 
    id. at 83-85,
    9 P.3d at 395-97, and defined an “injury by disease” as an
    injury that “generally developed gradually over a long period of
    time” as opposed to “result[ing] from a discrete event.”            
    Id. at 78,
    9 P.3d at 390.
    Although the court then characterized the issue before
    it as “constru[ing] the causation requirements applicable to the
    ‘injury-by-disease’ prong of HRS § 386-3,” 
    id. at 80,
    9 P.3d at
    392, the court was clearly focused on the “resulting from the
    nature of the employment” prong of injuries by disease.            Thus,
    the court defined an “occupational disease” as a disease
    -37-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    “resulting from the nature of the employment.”           Id. at 
    80, 9 P.3d at 392
    (citing Komatsu v. Bd. of Trustees, Employees’ Ret. Sys.,
    
    5 Haw. App. 279
    , 284, 
    687 P.2d 1340
    , 1344 (1984)) (emphasis
    added).   The court further developed the definition of an
    “occupational disease,” explaining that “‘an ailment does not
    become an occupational disease simply because it is contracted on
    the employer’s premises.’”       
    Id. (quoting Anderson
    v. General
    Motors Corp., 
    442 A.2d 1359
    , 1360 (Del. 1982)) (brackets
    omitted).    Rather,
    [t]here must be a recognizable link between the disease and
    some distinctive feature of the claimant’s job, common to
    all jobs of that sort. In other words, an ailment or
    disease is a compensable occupational disease if the
    employer’s working conditions produced the ailment as a
    natural incident of the employee’s occupation in such a
    manner as to attach a hazard distinct from and greater than
    the hazard attending employment in general.
    94 Hawai#i at 
    80, 9 P.3d at 392
    (emphases added) (citations and
    quotation marks omitted).       The Flor court then announced its
    three-part test for compensating an employee’s injury caused by
    disease under HRS § 386-3(a).        
    Id. Based on
    the facts of that
    case, the court determined that the claimant’s “disability,
    caused by hepatitis C,” was compensable “inasmuch as the
    Employers failed to demonstrate by substantial evidence that
    Flor’s disease (1) was not caused by conditions that were
    characteristic of or peculiar to her employment as a dental
    hygienist, (2) did not result from her actual exposure to such
    conditions, and (3) was not due to causes in excess of the
    ordinary hazards of employment in general.”           
    Id. at 84-85,
    9 P.3d
    at 396-97.
    -38-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    The Flor court distinguished its three-part test from
    the “unitary” or “nexus” test used for determining the
    compensability of injuries “by accident.”          Id. at 
    80, 9 P.3d at 392
    .        The unitary test “considers whether there is a sufficient
    work connection to bring the accident within the scope of the
    statute,” and “requires the finding of a causal connection
    between the injury and any incidents or conditions of
    employment.”        Tate v. GTE Hawaiian Tel. Co., 77 Hawai#i 100, 103,
    
    881 P.2d 1246
    , 1249 (1994).
    The Flor court did not examine whether the claimant’s
    injury by disease was compensable under the proximate cause
    analysis due to the factual nature of the case.            However, the
    court did not preclude circumstances in which an injury by
    disease claim would be compensable under a proximate cause
    analysis.        On the contrary, the Flor court expressly stated that
    “[w]hen a disease causing injury results from an identifiable
    accident,” or from a “discrete event—the time and place of which
    can be fixed,” “rather than from a peculiar risk of the
    employment, it should be compensated as an accidental injury.”
    
    Id. at 78,
    9 P.3d at 390 (emphasis added).          Thus, the purpose of
    the Flor test was to expand coverage under HRS § 386-3 in a case
    where the claimant would not have been able to show proximate
    cause under the unitary test; the purpose was not to supplant the
    proximate cause analysis.12
    12
    This is consistent with the purpose of occupational disease
    legislation generally. The distinction between injuries by accident and by
    disease originally developed because occupational diseases were excluded from
    -39-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Accordingly, the Flor test for compensability is
    limited to determining the compensability of injuries by disease
    “resulting from the nature of the employment.”           For injuries by
    disease “proximately caused by” the employment, we continue to
    apply the unitary test.13
    B.
    The relevant issue under the unitary or “work-
    connection approach” is simply whether there is a causal
    connection between the injury and any incidents or conditions of
    employment:
    The work-connection approach rejects the necessity of
    establishing temporal, spatial, and circumstantial proximity
    coverage under early workers’ compensation laws. See Larson’s § 52.02.
    Workers’ compensation statutes “were designed to substitute no-
    fault coverage for common law fault remedies,” which provided coverage for
    “accidental” injuries. 2 Employment Law § 7.24 Occupational disease (4th
    ed.). “Because occupational diseases were not conditions subject to tort
    liability, state legislatures did not address those particular problems,” and
    most early court decisions did not allow coverage for non-accidental
    illnesses. 
    Id. “[T]he earliest
    kind of occupational disease coverage in the
    United States,” beginning in the early 20th century, “took the form of general
    inclusion within the term ‘injury’ or within the term ‘disease’.” Larson’s §
    52.02.
    However, “[w]ith the expansion of occupational disease
    legislation, [the] contrast between accidental and occupational disease is
    gradually losing its importance, and awards are frequently made without
    specifying which category the injury falls in.” 
    Id. at §
    52.03[1].
    “Jurisdictions having general coverage of occupational disease now usually
    define the term to include any disease arising out of exposure to harmful
    conditions of the employment, when those conditions are present in a peculiar
    or increased degree by comparison with employment generally.” 
    Id. at §
    52-1.
    13
    This court has previously applied the unitary test in cases
    involving the compensability of an injury resulting from a disease or the
    aggravation of a pre-existing disease, without explicitly identifying whether
    it considered the injury to be an injury by accident or by disease under the
    statute. See Akamine, 
    53 Haw. 406
    , 
    495 P.2d 1164
    (awarding compensation for
    aggravation of heart condition resulting in death); Lawhead, 
    59 Haw. 551
    , 
    584 P.2d 119
    (holding that “a disease or illness such as influenza is an injury
    within the meaning of § 386-3” and awarding compensation because employee
    “contracted influenza as a result of her employment”). See also Chung, 
    63 Haw. 642
    , 
    636 P.2d 721
    (applying work-connection test to determine that
    claimant’s heart attack arose out of and in the course of employment based on
    evidence that claimant’s employment activities engaged claimant for long hours
    and “generated a substantial amount of mental and emotional stress which is
    strongly linked to the production of heart disease”).

    between the injury and employment. Instead, focusing on the
    injury’s origin rather than the time and place of its
    manifestation, the work-connection approach simply requires
    the finding of a causal connection between the injury and
    any incidents or conditions of employment.

    In 
    Akamine, 53 Haw. at 407-08
    , 495 P.2d at 1165-66, the
    court held that the employer and insurance carrier failed to
    overcome the presumption of compensability, where an employee
    died of a heart attack at work while he unloaded, stacked and
    handtrucked cargo.    The LIRAB had denied the workers’
    compensation claim filed by the employee’s dependents, reasoning
    that the employee’s death “was due to his cardiovascular disease
    of long standing and that it was not attributable to his
    employment[.]”    
    Id. at 407,
    495 P.2d at 1165.
    In reviewing this decision, the court noted that
    “[b]ecause of the relatively higher degree of uncertainty
    surrounding causation of heart diseases, the strength of the
    presumption is especially formidable” in “cardiac cases.”             
    Id. at 409,
    495 P.2d at 1167.     The court explained that the presumption
    “signals and reflects a strong legislative policy favoring awards
    in arguable cases.”

    495 P.2d at 1167.          One
    -41-

    expert testified that there was no connection between the
    employee’s death and his employment, based “on his belief that
    heart diseases originate relatively early in one’s life and [the
    employee’s] pre-existing pathological condition was the sole
    cause of death.”    
    Id. at 410-11,
    495 P.2d at 1167 (footnote
    omitted).    The expert further testified that the employee’s job
    was not “extremely exertional” and would not have precipitated a
    heart attack.    
    Id. at 411,
    495 P.2d at 1168.
    The court determined that it would give “little
    probative weight” to such testimony.        
    Id. at 410-11,
    495 P.2d at
    1167-68.    The court reasoned that “while it may be sound
    medically to say that the work did not ‘cause’ the attack, it may
    be bad law, because, [i]n general, existing law treats the
    slightest factor of aggravation as an adequate ‘cause’.”            
    Id. at 410,
    495 P.2d at 1167 (emphasis added).         Thus, it was “legally
    irrelevant” whether the employee’s heart attack “might have
    occurred at home, on the street or elsewhere while tending to his
    private affairs.    The only consideration should have been whether
    the attack in fact was aggravated or accelerated by his work
    activity.”    
    Id. at 413,
    495 P.2d at 1169 (emphasis added).
    Based on this standard, the court found that a doctor’s
    testimony that he was unable to render an opinion as to whether
    the heart attack was related to the employee’s work activity
    “represents a salient index of the absence of substantial
    evidence to the contrary.”      
    Id. at 414,
    495 P.2d at 1169
    (emphasis added).    The court found that the employee’s claim was
    -42-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    compensable, and reversed and remanded for a determination of the
    amount of the award.     
    Id. at 414,
    495 P.2d at 1170.
    Following Akamine, this court has continued to hold
    that “the slightest aggravation or acceleration of an injury by
    the employment activity mandates compensation.”           DeFries v. Ass’n
    of Owners, 999 Wilder, 
    57 Haw. 296
    , 309, 
    555 P.2d 855
    , 862 (1976)
    (holding that claimant was entitled to recover for injuries
    resulting from stumble that aggravated or accelerated the
    arthritic condition of his knee).         See 
    Chung, 63 Haw. at 651-52
    ,
    636 P.2d at 727-28 (claimant’s heart attack was aggravated or
    accelerated by work activity); Flor, 94 Hawai#i at 
    85, 9 P.3d at 397
    (applying principle that primary focus of medical testimony
    is “whether employment situation in any way contributed to the
    employee’s injury”); Korsak v. Haw. Permanente Med. Group, Inc.,
    94 Hawai#i 257, 260, 
    12 P.3d 357
    , 360 (App. 1999) (applying
    slightest aggravation test and comparing facts to Akamine, which
    held that “[t]he primary focus of the medical testimony should
    have been a discussion on whether the employment effort, whether
    great or little, in any way aggravated [the] heart condition
    which resulted in his death”) (quotation marks and citation
    omitted).
    In 
    Lawhead, 59 Haw. at 558
    , 584 P.2d at 124, the court
    held that “[i]n view of the broad scope of [HRS § 386-3], . . . a
    disease or illness such as influenza is an injury within the
    meaning of § 386-3.”     In that case, the claimant was a flight
    attendant.    
    Id. at 553,
    584 P.2d at 121.       On a certain flight,

    she “worked in the galley section of the aircraft where the
    temperature was extremely low.”          
    Id. During a
    stopover, she
    stayed in accommodations arranged by her employer, where the air
    was very dry due to a “defective heating and air-conditioning
    system.”     
    Id. She woke
    up the next day with a “dry and sore
    throat” and upon returning home she was diagnosed with influenza.
    
    Id. Based on
    these facts, the court held that the claimant
    was entitled to compensation.          
    Id. at 560,
    584 P.2d at 125-26.
    The court rejected the employer’s contention that the claim
    should be denied because the claimant “failed to show that she
    was exposed to an increased risk attributable to work.”               
    Id. at 560,
    584 P.2d at 125.        The court noted that a nearly identical
    argument was rejected as legally irrelevant in Akamine, and
    explained, “The relevant point is not whether a claimant would
    more likely have suffered an injury at work than elsewhere but
    whether her injury occurring in the course of employment was work
    related.”      
    Id. In announcing
    its holding, the court referenced
    the statutory language for injuries by disease: “[T]here was
    evidence that she suffered from an illness proximately caused by
    or resulting from the nature of her employment.              Since United
    failed to present substantial evidence to rebut the presumption
    that her claim was for a covered work injury, appellee must
    prevail.”      
    Id. at 560,

    In this case, the DOE failed to present substantial
    evidence to overcome the statutory presumption of compensability.
    As stated, “[t]he statue nowhere requires . . . some preliminary
    showing . . . before the presumption will be triggered.            Rather,
    HRS § 386-85 clearly dictates that coverage will be presumed at
    the outset, subject to being rebutted by substantial evidence to
    the contrary.”    
    Chung, 63 Haw. at 650-51
    , 636 P.2d at 727.
    Here, the evidence was undisputed that Van Ness had a
    pre-existing asthma condition.       It was also undisputed that
    exposure to vog aggravated Van Ness’s condition.           Dr. Mathison
    diagnosed Van Ness with “[m]ild persistent asthma with history of
    exacerbations with exposures to volcanic smoke-ash-pollution,”
    and Dr. Tom recommended that Van Ness be transferred out of Maui
    because of his “asthma condition, which is exacerbated by vog.”
    Dr. Arora’s supplemental report concluded that Van Ness’s medical
    history is “compatible with mild exacerbation of his asthma while
    in Maui because of vog conditions.”
    The State’s 2008 advisory further recognized that
    elevated levels of sulfur dioxide as a result of volcanic
    emissions “pose an immediate health threat to people who have
    asthma and other respiratory conditions.”         The State’s “Health
    Effects” notice confirmed that “[p]eople with asthma who are
    physically active outdoors are most likely to experience the
    health effects of [sulfur dioxide],” which may include “wheezing,
    chest tightness, and shortness of breath.”         Van Ness testified to
    -45-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    experiencing such health effects when exposed to vog at work.
    Thus, his asthma condition was clearly exacerbated and aggravated
    by exposure to vog.
    It was further undisputed that Van Ness faced actual
    exposure to vog while employed at Lahainaluna.          This was
    recognized by both the LIRAB and the ICA.         The LIRAB found that
    Van Ness’s “work or work environment posed no greater vog
    exposure than that posed to the general public,” (emphasis
    added), implicitly finding that Van Ness was exposed to vog at
    work, while the ICA expressly stated that it was “undisputed that
    Van Ness faced actual exposure to vog in his employment.”             
    2012 WL 6115601
    , at *4.    Additionally, there was evidence that the vog
    on Maui was particularly severe around December 2005.            Vice
    Principal Dennis, who did not have a pre-existing asthma
    condition, confirmed that she “experienced intense headaches”
    during that time because of the vog.
    Finally, Van Ness testified that his exposure to vog at
    Lahainaluna, coupled with the requirements of his employment, the
    layout of the campus, and the severity of the vog in late 2005,
    caused his condition to worsen.       Van Ness’s employment as a
    technology coordinator at Lahainaluna was affected by the campus’
    location and layout.     Lahainaluna’s campus is situated on a
    mountain side, with stairs providing most of the access to the
    school buildings.    Van Ness’s office was located at the highest
    elevation point of the campus.       During the seven to eight hours a
    day that he was generally present on campus, Van Ness estimated
    -46-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    that he spent less than five percent of his time in his office.
    In order to service the computers at the lower parts of the
    campus, Van Ness was required to repeatedly climb up and down the
    school stairs daily.     He estimated that there were 140 stairs or
    about “three or four floors” down to the parking lot, and then
    another “hike down” to the final section of buildings.            The
    stairs went “up the side of the hill” and there were also
    “switchbacks.”    Van Ness explained that it took “quite a bit of
    effort” and about twenty minutes for him to get back to his
    office from the administration building.
    Van Ness testified that the exposure to vog caused many
    issues with “strength” and his ability to breathe.           He testified
    that when the vog was severe, he experienced coughing and
    wheezing, as well as a “sharp” “stabbing pain” from coughing.
    This made it very difficult for him to move around the
    Lahainaluna campus.     His coughing worsened when he walked uphill
    and climbed stairs back to his office from the lower campus, and
    he would have to take breaks between stair levels because of the
    coughing and wheezing that the vog caused.
    Accordingly, it is clear that the “effort or strain”
    Van Ness experienced with his respiratory condition as a result
    of vog exposure “occur[ed] during the course of the employment
    and as an ordinary or usual incident of the work,” given that his
    employment required strenuous activity and the strenuous activity
    caused the exacerbation of his asthma.         Akamine, 53 Haw. at 
    413, 495 P.2d at 1169
    .     The LIRAB’s finding that Van Ness’s “work
    -47-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    environment posed no greater vog exposure than that posed to the
    general public” is inapposite, inasmuch as the “relevant point is
    not whether [Van Ness] would more likely have suffered an injury
    at work than elsewhere[,] but whether [his] injury occurring in
    the course of employment was work related.”          Lawhead, 59 Haw. at
    
    560, 584 P.2d at 125
    -26.
    The evidence offered by the DOE to rebut the statutory
    presumption was Dr. Arora’s opinion in his supplemental report
    that the exacerbation of Van Ness’s asthma was “temporary and
    reversible.”   However, as the court held in Akamine, “existing
    law treats the slightest factor of aggravation as an adequate
    ‘cause’” of injury.     53 Haw. at 
    410, 495 P.2d at 1167
    (emphasis
    added).
    Dr. Arora also concluded that it was “impossible to
    determine” if the exacerbation of Van Ness’s asthma was caused by
    the vog or by the diaphragmatic hernia that developed around the
    same time.   While the ICA relied on this opinion to conclude that
    Dr. Arora’s reports constituted substantial evidence for the
    LIRAB to conclude that Van Ness’s condition was unrelated to
    work, 
    2012 WL 6115601
    , at *6, the LIRAB did not rely on Dr.
    Arora’s opinion in this regard.       Furthermore, Dr. Arora’s opinion
    that it was impossible to determine the cause of the aggravation
    does not constitute substantial evidence rebutting the
    presumption.   On the contrary, pursuant to Akamine, doubt as to
    the cause of the injury “represents a salient index of the
    absence of substantial evidence” required to overcome the
    -48-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    presumption that the claim is compensable.         53 Haw. at 
    414, 495 P.2d at 1169
    (emphasis added).       In any event, the presumption of
    compensability and “the broad humanitarian purpose of the
    workers’ compensation statute . . . requires that all reasonable
    doubts be resolved in favor of the claimant.”          Lawhead, 59 Haw.
    at 
    560, 584 P.2d at 125
    (quotation marks and citations omitted)
    (emphasis added).
    The LIRAB, however, found that the “hazard from vog
    exposure [Van Ness] faced while on the campus of Lahainaluna
    School was no greater hazard or risk than that faced by others
    off of the campus,” and concluded that “[t]he nature and
    conditions of [Van Ness’s] employment did not accentuate the
    exposure.   Rather, the vog was in the air, and the general public
    breathed the same air.”
    As discussed, the evidence overwhelmingly demonstrated
    that Van Ness’s exposure to vog at work, combined with the
    surrounding circumstances of his employment and his pre-existing
    condition, resulted in the exacerbation of his asthma.            Thus, the
    aggravation of Van Ness’s asthma was causally connected to the
    “incidents or conditions” of his employment.          See 
    Chung, 63 Haw. at 648
    , 636 P.2d at 725 (“the work-connection approach simply
    requires the finding of a causal connection between the injury
    and any incidents or conditions of employment”).           The LIRAB’s
    finding and conclusion failed to properly consider Van Ness’s
    pre-existing condition and the fact that the general public was
    not exposed to the vog in the same manner as Van Ness.            Therefore
    -49-
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    the LIRAB’s finding is clearly erroneous and the conclusion of
    law is wrong.14
    The DOE failed to present substantial evidence to
    overcome the presumption that the aggravation of Van Ness’s
    asthma was an injury “by disease proximately caused by” his
    employment.    See Miyamoto v. Wahiawa General Hosp., 101 Hawai#i
    293, 310-11, 
    67 P.3d 792
    , 809-10 (App. 2003) (holding that LIRAB
    misapplied statutory presumption that claimant’s injuries were
    work-related, reversing LIRAB’s judgment and remanding for a
    determination of the amount of compensation to be awarded);
    Korsak v. Haw. Permanente Med. Group, Inc., 94 Hawai#i 257, 261-
    62, 
    12 P.3d 357
    , 361-62 (App. 1999) (reversing LIRAB’s decision
    denying benefits and remanding for determination of compensation
    and apportionment, given that undisputed facts were not
    sufficient “to constitute substantial evidence to rebut the
    presumption” of compensability), affirmed by 94 Hawai#i 297, 309,
    
    12 P.3d 1238
    , 1250 (2000) (affirming ICA’s reversal of LIRAB
    decision and ICA’s remand to the LIRAB for determination of

    It is somewhat unclear what standard the LIRAB applied in denying
    Van Ness’s claim, as the LIRAB referenced language consistent with Flor as
    well as language referring to the statutory standard for accidental injuries.
    As stated, the LIRAB erred in applying the Flor test. The LIRAB also erred in
    the way it applied the unitary work-connection test.
    The LIRAB’s pretrial order characterized the claim as an injury by
    accident, and the LIRAB’s decision concluded that Van Ness “did not sustain a
    personal injury to his respiratory system, on December 23, 2005, arising out
    of and in the course of employment.” The LIRAB’s basis for its conclusion was
    simply that Van Ness “was not at work or even on Maui on December 23, 2005.”
    However, as stated, the work-connection approach “rejects the necFessity of
    establishing temporal, spatial, and circumstantial proximity between the
    injury and employment.” 
    Chung, 63 Haw. at 648
    , 636 P.2d at 725. The focus is
    on the “injury’s origin rather than the time and place of its manifestation.”
    
    Id. Accordingly, the
    LIRAB clearly erred in its application of the unitary
    test.

    Akamine, 53 Haw. at 415

    Accordingly, Van Ness’s claim is for a covered work
    injury under HRS § 386-3.
    VII.
    Based on the foregoing, we vacate the ICA’s judgment
    and the LIRAB’s decision and order.          The case is remanded to the
    LIRAB for a determination of the amount of compensation to be
    awarded.15
