    INDUSTRIES,
    Respondent.
    BASSETT, JPT.1 – SEFNCO Communications, Inc. appeals two citations issued by the
    Department of Labor and Industries (DLI) under the Washington Industrial Safety and Health Act
    of 19732 (WISHA) following the injury to one of its employees when he contacted an energized
    power line during the installation of a telecommunications line. The Board of Industrial Insurance
    Appeals (Board) upheld the citations, one for a violation of former WAC 296-32-220(10)(a)
    (2007), a serious violation, for allowing the injured employee to come too close to energized power
    lines, and the other for a violation of former WAC 296-32-230(4)(c) (2014), a general violation,
    for having an employee at the job site who did not have the required first aid training.

    Chapter 49.17 RCW.
    No. 55458-5-II
    SEFNCO argues that the citation for the serious violation was improper because the
    findings that the employee was a supervisor and that SEFNCO had constructive knowledge of the
    serious violation are not supported by substantial evidence. SEFNCO further argues that even if
    the constructive knowledge finding was supported by substantial evidence, SEFNCO established
    the defense of unpreventable employee misconduct under RCW 49.17.120(5)(a). SEFNCO also
    argues that the evidence was insufficient to support the citation for the general violation because
    the DLI failed to prove that the employee at issue was required to have first-aid training.
    We hold that (1) substantial evidence supports the finding that the injured employee was a
    supervisor, (2) substantial evidence supports the Board’s constructive knowledge finding, (3) the
    Board’s findings are inadequate to allow review of its conclusion that the unpreventable employee
    misconduct defense did not apply, and (4) SEFNCO’s argument that the DLI failed to prove that
    the employee who was the subject of the general violation was required to have first aid training
    under former WAC 296-32-230(4)(c) has no merit. Accordingly, we remand this matter to the
    Board to make the necessary factual determinations and to determine whether SEFNCO’s
    unpreventable employee misconduct defense applies. We otherwise affirm.
    FACTS
    I. CITATIONS AND CORRECTIVE NOTICE OF REDETERMINATION
    On July 11, 2017, Kenneth Nelson, a SEFNCO employee, was injured when he contacted
    an energized power line while working on a nearby telecommunications line. The DLI investigated
    the incident and issued four citations, two of which are relevant in this appeal.
    The first relevant citation was for a violation of former WAC 296-32-220(10)(a), a
    “[s]erious” violation, based on SEFNCO’s failure to ensure that Nelson “did not approach or take
    2
    No. 55458-5-II
    any conductive objects, to include the employee, closer to any electrically energized overhead
    lines” than allowed under Table 1 of chapter 296-32 WAC. Clerk’s Papers (CP) at 39. The second
    relevant citation was for a violation of former WAC 296-32-230(4)(c), a general violation, based
    on SEFNCO’s failure to provide first aid training to the employee who was assisting Nelson at the
    time of the incident.
    The DLI issued corrective notices of redetermination (CNRs) rejecting the assertion that
    the DLI had not established the knowledge element and SEFNCO’s unpreventable employee
    misconduct defense. SEFNCO appealed to the Board.
    II. PROPOSED DECISION AND ORDER AND BOARD’S DECISION
    Following a hearing at which evidence and testimony was taken, an industrial appeals
    judge (IAJ) issued a proposed decision and order affirming the CNRs for the violations of former
    WAC 296-32-220(10)(a) and former WAC 296-32-230(4)(c).3
    The introduction of the IAJ’s proposed decision and order stated:
    SEFNCO Communications, Inc. filed an appeal from a [CNR] that found
    two serious violations and one general violation. The first serious violation is for
    failing to ensure that an employee not come in contact with an energized power line
    and the second is for not maintaining the scene of the accident so that it could be
    adequately inspected by the [DLI]. . . . The general violation is because an
    employee did not have first aid/CPR training at the time an employee was injured.
    The employer’s defense to the first violation is that this was an unforeseen accident
    and secondarily that there was employee misconduct. The [DLI] has proven this
    violation with the employer’s constructive knowledge of the hazard and the
    misconduct defense does not apply. . . . The general violation has been adequately
    proven because Mr. James, Mr. Nelson’s co-worker on the day of accident, did not
    have the proper first aid training. The CNR is AFFIRMED AS MODIFIED.
    3
    We note that although the parties did not present closing argument at the hearing before the IAJ,
    they did submit post-hearing briefing. In their post-hearing briefing, both parties discussed the
    reasonable diligence standard that we apply below.
    3
    No. 55458-5-II
    Id. at 48 (emphasis added).
    In the “discussion” section of the proposed decision and order, the IAJ summarized the
    testimony and discussed the issues.4 Id. (capitalization omitted). The IAJ’s summary of the
    testimony stated that on July 11, 2017, Nelson, a “splicer/aerial technician for SEFNCO,”
    sustained a burn injury after contacting a high voltage electrical wire. Id.
    Nelson testified that on the day of the accident, he was “build[ing] a new strand of cable
    and connect[ing] it to a business.” Id. When Nelson arrived at the work site, he photographed an
    area of the work zone in which he had concern about his ability to perform the job safely due to
    ground clearance issues. After sending a photograph to his supervisor Timothy Lundell and
    speaking with Lundell, Nelson proceeded with the work.
    As this work progressed, Nelson “used a lasher to put the new line of fiber optics onto the
    existing line.” Id. During this process, Nelson was in an elevated bucket truck and was working
    with a “ground hand, Nathan James.” Id. at 49. The IAJ summarized the accident as follows:
    The accident occurred when the lasher got hung up in the trees and Mr. Nelson then
    got into the bucket of the boom truck and raised it to try to maneuver the lasher.[5]
    When the cable with the lasher freed the bucket on the boom bounced, causing the
    power line to make contact with his right shoulder. Mr. Nelson fell into the bucket
    and Mr. James lowered it to the ground.
    Id. at 49.
    4
    SEFNCO does not challenge the IAJ’s summary of the testimony. In fact, SEFNCO largely relies
    on the IAJ’s summary of testimony in its opening brief. And our review of the record shows that
    the summary is accurate. Where necessary, we have included footnotes noting additional relevant
    testimony.
    5
    Nelson also testified that he “didn’t realize how far [he] had boomed up with the cable laying on
    [his] basket instead of in a rope.” CP at 266.
    4
    No. 55458-5-II
    Lundell, a construction manager on the project, testified that before the work started on
    this project, a SEFNCO engineer had reviewed the site and developed a construction plan. “This
    report could include hazards of the job.” Id.
    Lundell also “described the minimum approach distance (MAD) for working around
    electrical wires.” Id. Lundell stated that SEFNCO “[e]mployees are trained to supply sufficient
    space away from the power lines because the electricity will take the path of least resistance, which
    can be the human body.” Id. Lundell testified that Nelson was the only person to have been injured
    in this way that Lundell was aware of.
    Lundell further “described the bucket truck used by Mr. Nelson and how the bucket will
    bounce.” Id. Lundell stated that he had spoken with Nelson on the phone before Nelson started
    working and was aware of the sag in the lines. But Lundell stated that the sag in the lines that
    Nelson was concerned about was common and that he (Lundell) “did not believe that there would
    be a problem with MAD in doing this work,” even though running the new line through the trees
    in the area “could be a challenge.” Id. Lundell also testified that Nelson was “in charge on this job
    site,” but that Nelson “did not have the authority to perform tasks such as hiring or firing.” Id.
    Rod Julian, “the statewide telecom health and safety officer for the [DLI],” testified that
    following an inspection of the site after the accident, the DLI “cited SEFNCO with a serious
    violation of WAC 296-32-220(10)(a) because the employer failed to ensure that a SEFNCO
    employee not come into contact with an energized power line.” Id. at 49, 50. Julian also determined
    that there were 7200 volts in the line, which allowed him to establish the proper distances for
    MAD.
    5
    No. 55458-5-II
    Julian also testified that the DLI issued “[a] general violation of WAC 296-32-230(4)(c) .
    . . because of the lack of first aid/CPR training for Mr. James.” Id. at 50. Julian testified that he
    examined SEFNCO’s records and, although James was “slated” to have the training soon, there
    was no record of James having received first aid-CPR training by the time of the accident. Id.
    Julian agreed that “Nelson was not a company supervisor,” but Julian testified that Nelson
    had been in charge of James when this accident occurred. Id. at 51. Julian stated that “[h]e believed
    that Mr. Nelson was a competent worker at this site and that the employer could rely on his abilities
    and that under the company plan no work was to be performed near the power line.”6 Id.
    Rocky Wallace, SEFNCO’s safety and compliance officer, testified about SEFNCO’s
    training, disciplinary program, safety audits, and accident prevention programs. Wallace
    “reviewed the work Mr. Nelson was to perform on July 11, 2017 and, [stated that] if the trees seen
    in [the photograph Nelson had taken] were trimmed, he did not see a hazard in performing this
    work.” Id. at 51. Wallace also “identified the lasher and described how [ ]it works.” Id.
    Additionally, “Wallace agreed that Mr. Nelson was the competent person on site and responsible
    for getting the job done and directing the crew.” Id.
    Chris McBride, a lead for SEFNCO, testified that he and his crew were assigned “to secure
    the work area” after the accident. Id. McBride had worked with Nelson “on numerous occasions,”
    and was “well aware of MAD and has received training on it.” Id. McBride also reviewed Nelson’s
    photograph and stated that “he did not observe any issue with power line difficulties if the trees
    were trimmed.” Id.
    6
    Julian also acknowledged that “[a]nybody who works in a bucket knows that it bounces.” Id. at
    346.
    6
    No. 55458-5-II
    The IAJ then discussed the issues in light of this testimony:
    There is no question that Mr. Nelson sustained injuries when he came within
    the MAD while stringing a fiber optic line while he was in the elevated bucket
    attempting to extricate the lasher from the trees. The employer would like me to
    classify this situation as an unforeseeable mishap with their highly experienced
    lineman momentarily entering the MAD when the bucket unexpectedly bounced.
    The [DLI] believes that they have shown all of the elements necessary to sustain
    these alleged violations for which the employer had actual or constructive
    knowledge. Constructive knowledge comes from the view of the project prior to the
    commencement of work. Mr. Nelson took a photograph from the first pole and spoke
    with his supervisor about ground clearance, with it being known that the trees
    would have to be trimmed in order to string the new line. Mr. Nelson could have
    performed all of his necessary work outside the MAD, but with this tree situation it
    was foreseeable that the lasher could become tangled in the limbs and become
    necessary that the boom truck with its bucket be used to untangle the equipment.
    The witnesses all agree that it is known that the bucket will bounce and with the
    addition of the lasher’s weight the bucket can bounce more. This is what occurred
    to Mr. Nelson and caused the violation with electrical contact within the MAD. . . .
    The employer put forth the defense of unpreventable employee misconduct
    and noted that while Mr. Nelson was the supervisor on this job he did not have the
    power to hire and fire. They would like me to use these facts and the Board’s recent
    decision in In re Tyson Fresh Meats, [No. 17 W1079 (Bd. of Indus. Ins. Appeals
    Dec. 17, 2018)][7] to determine that the violations should be vacated. I do not find
    that the facts in the present case meet those necessary for me to accept the
    employer’s position. The supervisor’s conduct in Tyson go way beyond what was
    done by Mr. Nelson. As such, I rely more on the Board’s analysis in In re Jornada
    Roofing 1, Inc., [No. 08 W1050 (Bd. of Indus. Ins. Appeals Jan. 27, 2010)];[8] and
    In re Greater American Construction, [No. 12 W1058 (Bd. of Indus. Ins. Appeals
    Aug. 16, 2013)],[9] and believe that the supervisor’s participation in the safety
    violation weighed heavily in favor of assessing that unpreventable employee
    misconduct did not occur. A similar stance was taken by the Court of Appeals in
    Potelco, Inc. v. Department of Labor and Indus., 
    194 Wn. App. 428
    [, 
    377 P.3d 251
    ]
    (2016). I do not believe that this defense is applicable to SEFNCO in this case
    because of Mr. Nelson’s supervisory tasks and the facts presented.

    No. 55458-5-II
    The [DLI] believes that SEFNCO did not contest the fact that Nathan James,
    Mr. Nelson’s ground hand, did not have first aid training prior to engaging in this
    work and therefore violated [former] WAC 296-32-230(4)(c). SEFNCO indicates
    that he was scheduled to have this training and does not believe it was appropriate
    for Mr. James to have this training in order to work in the field with Mr. Nelson,
    who had the proper first-aid training. Mr. James had only worked for the employer
    for a matter of days, but this does not alleviate the need for him to be properly
    trained before going into the field to assist Mr. Nelson. He needed the first aid
    training prior to doing so in order to be trained to assist if an injury occurred,
    which happened here, to his co-worker. This violation is affirmed.
    Id. at 53-54 (emphasis added).
    In addition, the proposed decision and order included brief “findings of fact” and
    “conclusions of law” sections that stated:
    FINDINGS OF FACT
    ....
    2.     On July 11, 2017 in Fife, Washington, Kenneth Nelson, an employee of
    SEFNCO Communications, Inc. entered the [MAD] for working around
    electrical wires, a serious violation of [former] WAC 296-32-220(10)(a), and
    sustained significant burning injuries.
    3.     At the time of the July 11, 2017 accident, Mr. Nelson was the supervisor in
    charge of conducting the necessary work.
    ....
    5.     On July 11, 2017, Nathan James, an employee of SEFNCO Communications,
    Inc., was working with Kenneth Nelson and had not yet received first aid
    training in violation of [former] WAC 296-32-230(4)(c).
    ....
    CONCLUSIONS OF LAW
    ....
    2.     On July 11, 2017, SEFNCO Communications, Inc. committed a serious
    violation of [former] WAC 296-32-220(10)(a) as alleged in Item 1-1 of [CNR]
    No. 317946524. . . .
    8
    No. 55458-5-II
    3.     The violation of [former] WAC 296-32-220(10)(a) committed on July 11,
    2017 was not the result of unpreventable employee misconduct as the term is
    used in RCW 49.17.120(5).
    ....
    5.     By July 11, 2017, Nathan James had not received first aid training and
    SEFNCO Communications, Inc., committed a general violation of [former]
    WAC 296-32-230(4)(c).
    Id. at 54-55. The IAJ affirmed the serious and general violations.
    SEFNCO petitioned for review of the IAJ’s decision. The Board granted review and
    concluded that the IAJ’s proposed decision and order was “supported by the preponderance of the
    evidence and [was] correct as a matter of law.” Id. at 67. The Board adopted the IAJ’s proposed
    decision and order by reference.
    SEFNCO appealed the Board’s decision to the superior court. The superior court affirmed
    the Board’s decision. SEFNCO appeals.

    ANALYSIS
    I. SERIOUS VIOLATION: VIOLATION OF MAD
    SEFNCO first challenges the finding of a serious violation of former WAC 296-32-
    220(10)(a).10 We affirm that finding.
    A. LEGAL PRINCIPLES
    We review [the Board’s] decisions directly based on the record before the
    agency. W. Oilfields Supply v. Dep’t of Labor & Indus., 1 Wn. App. 2d 892, 900,
    
    408 P.3d 711
     (2017). We review challenged findings of fact to determine whether
    they are supported by substantial evidence and, if so, whether the findings support
    the conclusions of law. J.E. Dunn Nw., Inc. v. Dep’t of Labor & Indus., 
    139 Wn. App. 35
    , 42, 
    156 P.3d 250
     (2007). Substantial evidence is “evidence ‘in sufficient
    quantum to persuade a fair-minded person of the truth of the declared premise.’ ”
    J.E. Dunn Nw., 139 Wn. App. at 43, 
    156 P.3d 250

    90 Wn.2d 384
    , 390-91, 
    583 P.2d 621
     (1978)).
    We do not reweigh the evidence on appeal. Potelco, Inc.[,194 Wn. App. at
    434]. In determining whether substantial evidence supports [the Board’s] findings,
    we view the evidence in the light most favorable to the party that prevailed before
    the [Board]. Potelco, 194 Wn. App. at 434, 
    377 P.3d 251
    . Unchallenged findings
    of fact are verities on appeal. Mid Mountain Contractors, Inc. v. Dep’t of Labor &
    Indus., 
    136 Wn. App. 1
    , 4, 
    146 P.3d 1212
     (2006). If substantial evidence supports
    the findings of fact, we decide if those findings support the [Board’s] conclusions
    of law. Potelco, 194 Wn. App. at 434, 
    377 P.3d 251
    .

    Former WAC 296-32-220 provided, in part:
    (10) Power exposures.
    (a) The employer shall ensure that no employee approaches or takes any
    conductive object closer to any electrically energized overhead power lines and
    parts than prescribed in Table 1 unless:
    (i) The employee is insulated or guarded from the energized parts
    (insulating gloves rated for the voltage involved shall be considered adequate
    insulation), or
    (ii) The energized parts are insulated or guarded from the employee and any
    other conductive object at a different potential, or
    (iii) The power conductors and equipment are deenergized and grounded.
    10
    No. 55458-5-II
    B. SUPERVISOR FINDING
    The Board found that Nelson was a supervisor. SEFNCO argues that the evidence did not
    support this finding because Nelson did not have the authority to hire or fire workers, set wages,
    or approve vacation. We disagree.
    An employee does not have to hold the official title of foreman or supervisor to be
    considered a supervisor for the purposes of imputing knowledge onto the employer. See Mountain
    States Contractors, LLC v. Perez, 
    825 F.3d 274
    , 284-85 (6th Cir. 2016).11 It is sufficient that the
    employee had significant control over the actual work in practice and the ability to stop work when
    faced with clear safety hazards. See 
    id.
    Here, it was undisputed that Nelson was in charge of the work being done and that he had
    the ability to stop this work if the team encountered any safety hazards. Lundell, Julian, Wallace,
    and McBride testified that Nelson was in charge on the job site, that it was his job to direct the
    crew doing the work, that he was responsible for identifying hazards, and that he could terminate
    the work if he discovered any hazards. This testimony is substantial evidence that Nelson was
    acting as a supervisor and supports the Board’s finding. Accordingly, this argument fails.

    C. CONSTRUCTIVE KNOWLEDGE
    To establish a prima facie case of a serious WISHA safety violation, the DLI is required
    to prove that
    (1) the cited standard applies, (2) the requirements of the standard were not met, (3)
    employees were exposed to[,] or had access to[,] the violative condition, (4) the
    employer knew or through the exercise of reasonable diligence could have known
    of the violative condition, and (5) there is a substantial probability that death or
    serious physical harm could result from the violative condition.
    Ostrom Mushroom Farm Co. v. Dep’t of Labor & Indus., 13 Wn. App. 2d 262, 272, 
    463 P.3d 149
    (2020); see also RCW 49.17.180(7).12
    SEFNCO argues that the Board’s finding that SEFNCO had constructive knowledge of the
    violative condition was not supported by substantial evidence. We disagree.13
    Again, to establish a prima facie case of a serious WISHA safety violation, the DLI is
    required to prove, in part, that “the employer knew or through the exercise of reasonable diligence
    could have known of the violative condition.” Ostrom Mushroom Farm, 13 Wn. App. 2d at 272.
    “ ‘Reasonable diligence’ includes the obligation of an employer to inspect the work site, anticipate
    12
    RCW 49.17.180(7) provides:
    For the purposes of this section, a serious violation shall be deemed to exist in a
    workplace if there is a substantial probability that death or serious physical harm
    could result from a condition which exists, or from one or more practices, means,
    methods, operations, or processes which have been adopted or are in use in such
    workplace, unless the employer did not, and could not with the exercise of
    reasonable diligence, know of the presence of the violation.
    At the time of the incident, this subsection was numbered as subsection (6). See former RCW
    49.17.180(6) (2010). Because the content of the subsection has not changed, we cite to the current
    version of the statute.
    13
    SEFNCO also argues that the DLI failed to establish that SEFNCO had actual knowledge of the
    violative condition. But as SEFNCO acknowledges, the Board did not find that the DLI had
    established actual knowledge of the violative condition.

    Constructive knowledge may be proved through evidence that a violation was in
    plain view. Such knowledge is established where the violation was ‘readily
    observable or in a conspicuous location in the area of the employer’s crews.’
    Moreover, when a supervisor has actual or constructive knowledge of a safety
    violation, such knowledge can be imputed to the employer.

    App. at 207); see also Bayley Constr., 10 Wn. App. 2d at 783. Notably, “the applicable standard
    here is whether [the employer] knew or [c]ould have known of the violative condition—not
    whether the behavior that led to the violation was foreseeable.” Potelco, 194 Wn. App. at 440
    (emphasis altered).
    Although not expressly designated as a finding of fact or conclusion of law, the discussion
    section of the Board’s decision contains a constructive knowledge finding:
    Constructive knowledge comes from the view of the project prior to the
    commencement of work. Mr. Nelson took a photograph from the first pole and
    spoke with his supervisor about ground clearance, with it being known that the trees
    would have to be trimmed in order to string the new line. Mr. Nelson could have
    performed all of his necessary work outside the MAD, but with this tree situation
    it was foreseeable that the lasher could become tangled in the limbs and become
    necessary that the boom truck with its bucket be used to untangle the equipment.
    The witnesses all agree that it is known that the bucket will bounce and with the
    addition of the lasher’s weight the bucket can bounce more. This is what occurred
    to Mr. Nelson and caused the violation with electrical contact within the MAD.
    CP at 52 (emphasis added).
    The Board’s application of foreseeability standard when determining whether SEFNCO
    had constructive knowledge of the violative condition was error. To establish constructive
    13
    No. 55458-5-II
    knowledge, the DLI was not required to prove that the behavior that caused the violation was
    foreseeable. Potelco, 194 Wn. App. at 440. Rather, it was required to show that SEFNCO, with
    the exercise of reasonable diligence, knew or could have known of the violative condition, here
    that Nelson was conducting his work in a way that risked violating the MAD and coming too close
    to the energized line. Id. But we can still affirm the Board if substantial evidence supports the
    constructive knowledge finding under the proper standard. Erection Co., 160 Wn. App. at 205.
    The employer has constructive knowledge if, had it exercised reasonable diligence, it could
    have known of the violative condition. Id. “ ‘Reasonable diligence’ includes the obligation of an
    employer to . . . anticipate hazards that employees may be exposed to, and take measures to prevent
    the occurrence of a violative condition.” Bayley Const., 10 Wn. App. 2d at 783. And, as previously
    noted, “when a supervisor has actual or constructive knowledge of a safety violation, such
    knowledge can be imputed to the employer.” Potelco, 194 Wn. App. at 440. Nelson was a
    supervisor. His constructive knowledge of a violative condition could be imputed to SEFNCO.
    Nelson’s proximity to the energized line combined with the bucket’s bouncing created the
    violative condition; with the exercise of reasonable diligence, he should have anticipated this
    hazard and taken measures to prevent the occurrence of this condition. The testimony established
    that “[a]nybody who works in a bucket knows that it bounces.” CP at 346. A reasonable person
    would know that if the weight of the lasher and cable was suddenly removed from the bucket, the
    bucket would bounce. Further, Nelson testified that he “didn’t realize how far [he] had boomed
    up,” and was therefore unaware of how close to the charged lines he was, while trying to extricate
    the lasher. Id. at 266.
    14
    No. 55458-5-II
    Taking this evidence in the light most favorable to the DLI, Nelson, with the exercise of
    reasonable diligence, could have known how close to the energized lines he was, could have
    anticipated that the bucket would bounce into the MAD once the lasher was released, and thus
    could have anticipated the existence of a violative condition and should have taken measures to
    prevent the violative condition. Thus, the Board’s constructive knowledge element is supported by
    substantial evidence.
    D. UNPREVENTABLE EMPLOYEE MISCONDUCT DEFENSE
    SEFNCO argues that the evidence did not support the Board’s conclusion that SEFNCO
    failed to establish its unpreventable employee misconduct defense. The Board’s findings are
    insufficient to allow for our review of this issue.
    RCW 49.17.120(5)(a) provides,
    No citation may be issued under this section if there is unpreventable employee
    misconduct that led to the violation, but the employer must show the existence of:
    (i) A thorough safety program, including work rules, training, and
    equipment designed to prevent the violation;
    (ii) Adequate communication of these rules to employees;
    (iii) Steps to discover and correct violations of its safety rules; and
    (iv) Effective enforcement of its safety program as written in practice and
    not just in theory.
    Proof of this defense is “more rigorous” and more difficult when a supervisor is involved
    in the violation because a supervisor’s involvement in the violation “raises an inference of lax
    enforcement and/or communication of the employer’s safety policy.” Potelco, 194 Wn. App. at
    437. But a supervisor‘s participation in or failure to enforce a safety rule does not preclude the
    defense of unpreventable employee misconduct, it merely “weighs against it.” Id.
    “[F]indings must be made on all material issues in order to inform the appellate court as
    to ‘what questions were decided by the trial court, and the manner in which they were decided’ ”

    91 Wn.2d 704
    , 707, 
    592 P.2d 631
     (1979)). In the absence of findings on all material issues, the remedy is not for us make our
    own findings, but, rather, to remand the matter to the Board to make the necessary factual
    determinations and to determine whether SEFNCO’s unpreventable employee misconduct
    defense applies. See id. at 444-45.
    The Board’s decision states that the Board did “not believe that this defense is applicable
    to SEFNCO in this case because of Mr. Nelson’s supervisory tasks and the facts presented.” CP at
    52. But the only finding of fact relevant to this defense was the finding that Nelson was a supervisor
    at the time of the incident. Although the Board’s references to Joranda Roofing 1 and Greater
    American Construction suggest that the Board understood that Nelson’s supervisory status did not
    alone preclude this defense, nothing in the Board’s decision addressed any of the statutory
    elements of the defense. Because Nelson’s supervisory status is not dispositive, the statutory
    elements are clearly material to whether the defense applies. Without additional findings related
    to the elements of the defense, we cannot determine whether the Board’s conclusion that the
    defense did not apply was supported by the evidence. Accordingly, we remand this matter back to
    the Board to make the necessary factual determinations and to determine whether SEFNCO’s
    unpreventable employee misconduct defense applies. See Federal Signal, 
    125 Wn.2d at 423

    II. GENERAL VIOLATION: FIRST AID TRAINING
    SEFNCO argues that the DLI failed to establish the general violation. SEFNCO contends
    that the DLI failed to prove that James was required to have first aid training under former WAC
    296-32-230(4)(c). We disagree.
    The resolution of this issue requires us to interpret former WAC 296-32-230. We review
    WAC regulations de novo with the goal of determining and giving effect to the intent of the
    regulation. Erection Co., 160 Wn. App. at 201; Dep’t of Ecology v. Campbell & Gwinn, LLC, 
    146 Wn.2d 1
    , 9, 
    43 P.3d 4
     (2002).
    “If an administrative rule or regulation is clear on its face, its meaning is to be derived
    from the plain language of the provision alone.” Dep’t of Licensing v. Cannon, 
    147 Wn.2d 41
    , 55,
    
    50 P.3d 627
     (2002). We “will neither read matters into a [regulation] that are not there nor modify
    a [regulation] by construction.” Rushing v. ALCOA, Inc., 
    125 Wn. App. 837
    , 840, 
    105 P.3d 996
    (2005).
    Former WAC 296-32-230, provided in part,
    Training. (1) Employers shall provide training in the various precautions and safe
    practices described in this section and shall insure that employees do not engage in
    the activities to which this chapter applies until such employees have received
    proper training in the various precautions and safe practices required by this
    section. . . .
    (2) Where training is required, it shall consist of on-the-job training or
    classroom-type training or a combination of both.
    ....
    (4) Such training shall, where appropriate, include the following subjects:
    (a) Recognition and avoidance of dangers relating to encounters with
    harmful· substances, and animal, insect, or plant life.
    (b) Procedures to be followed in emergency situations, and
    (c) First-aid training, including instruction in artificial respiration.
    (Emphasis added).
    17
    No. 55458-5-II
    SEFNCO contends that former WAC 296-32-230(4)(c) required first aid training only
    “where appropriate” and that first aid training was not “appropriate” here because there was no
    evidence that James was required at the job site and, therefore, “there could be no reliance on his
    first-aid skills in the event of an accident.” Br. of Appellant at 36. But the plain language of the
    rule states that employees engaging in activities covered by this chapter must have the required
    training, and we will not read an additional requirement into the rule that is not there. Former WAC
    296-32-230(1); Rushing, 125 Wn. App. at 840. Regardless of whether James was required at this
    job site, there is no dispute that he was there, that he was engaging in work covered by these rules,
    and that he had not yet received his first aid training. Accordingly, this argument fails.
    SEFNCO further argues that the DLI did not prove that all workers at a site, especially
    trainees, must be trained. The plain language of the rule states that it applies to employees engaging
    in the type of work in which James was engaging. The rule does not say that only some of the
    employees at the site must be trained; nor does it differentiate between trainees, probationary
    employees, or permanent employees. Again, we will not read language into a rule that is not there.
    Rushing, 125 Wn. App. at 840. Accordingly, this argument fails.
    Finally, SEFNCO argues that the DLI failed to prove that first aid training was
    “appropriate” because there was no proof that the job site was far from medical care. Br. of
    Appellant at 36. The rule does not state that first aid training is required only when the employees
    are working far from medical care, and we will not read such a requirement into the rule. Rushing,
    125 Wn. App. at 840. The need for emergency care could be instantaneous, so it is irrelevant how
    far away medical assistance is located. Again, this argument fails. SEFNCO does not show that
    18
    No. 55458-5-II
    the Board erred when it concluded that SEFNCO had violated former WAC 296-32-230(4)(c).
    Accordingly, we affirm the citation for this violation.
    CONCLUSION
    We hold that (1) substantial evidence supports the finding that Nelson was a supervisor,
    (2) substantial evidence supports the Board’s constructive knowledge finding, (3) the Board’s
    findings are inadequate to allow review of its conclusion that the unpreventable employee
    misconduct defense did not apply, and (4) SEFNCO’s argument that the DLI failed to prove that
    James was required to have first aid training under former WAC 296-32-230(4)(c) has no merit.
    Accordingly, we remand this matter to the Board to make the necessary factual determinations and
    to determine whether SEFNCO’s unpreventable employee misconduct defense applies. We
    otherwise affirm.
    A majority of the panel having determined that this opinion will not be printed in the
    Washington Appellate Reports, but will be filed for public record in accordance with RCW
    2.06.040, it is so ordered.
    BASSETT, J.P.T.
    I concur:
    PRICE, J.
    19
    No. 55458-5-II
    MAXA, J. (dissenting in part) – To establish a serious violation of the Washington
    Industrial Safety and Health Act of 1973 (WISHA), chapter 49.17 RCW, the Department of
    Labor and Industries (DLI) must prove that “the employer knew or through the exercise of
    reasonable diligence could have known of the violative condition.” Ostrom Mushroom Farm
    Co. v. Dep’t of Labor & Indus., 13 Wn. App. 2d 262, 272, 
    463 P.3d 149
     (2020). This
    requirement necessarily means that the violative condition must exist before an accident occurs.
    An employer cannot have actual or constructive knowledge of a violative condition that does not
    yet exist.
    Here, the only violative condition occurred at the instant that Kenneth Nelson was
    injured. DLI has not alleged or proved that any safety violations existed until the bucket jumped
    and Nelson hit the energized power line. Therefore, SEFNCO (through its supervisor Nelson)
    did not know and could not have known of the violative condition before Nelson was injured.
    This means that DLI cannot satisfy the knowledge requirement.
    The purpose of WISHA is to “assure, insofar as may reasonably be possible, safe and
    healthful working conditions for every [person] working in the state of Washington.” RCW
    49.17.010. Here, SEFNCO provided a safe workplace. Nelson’s injury did not occur because
    SEFNCO knew or should have known of an existing violative condition and failed to correct that
    condition. A violative condition did not cause the accident. Instead, the accident caused the
    violative condition. The injury occurred because Nelson made a mistake that caused a violation
    of a safety regulation. SEFNCO could not have been aware of the violation until after it had
    occurred.
    20
    No. 55458-5-II
    I would hold that DLI did not prove that SEFNCO had constructive knowledge of a
    violative condition before Nelson was injured. Therefore, I dissent regarding violation of former
    WAC 296-32-220(10)(a) (2007). I agree that DLI has shown a violation of the first aid training
    requirement, former WAC 296-32-230(4)(c) (2014).
