S. POWELL, J.
{¶ 1} Plaintiff-appellant, Lila Marcus, appeals the judgment of the Clermont County
Common Pleas Court excluding the testimony of appellant's expert witness and granting
summary judgment in favor of defendants-appellees, Rusk Heating & Cooling, Inc. and its
president, Steven J. Morrison (collectively, "Rusk"), Apollo Heating and Air Conditioning, Inc.
and Apollo Quality Heating & Cooling (collectively, "Apollo"), and Tribble Refrigeration, L.L.C.,
Tribble Refrigeration Co., and James Tribble (collectively, "Tribble").
Statement of Facts
{¶ 2} In March 2004, Rusk installed a Carrier Oil Furnace in appellant's residence
located in Milford, Clermont County, Ohio. Rusk also responded to appellant's repeated
service calls over the next few years due to malfunctioning issues with the furnace. Appellant
and Rusk continually disagreed upon the quality of Rusk's service of the furnace and,
ultimately, Rusk refunded the full contract price of the furnace to appellant. Appellant then
sought the services of Apollo and Tribble to repair the furnace.
{¶ 3} In January 2008, the furnace experienced a "puff back" where the furnace
malfunctioned or misfired, resulting in the disbursement of oily soot and vapors through the
furnace's heating ductwork and into the living area of appellant's home, leaving a grimy, oily
coating on floors, walls, furniture, and other exposed areas of the home. Also around this
time, appellant was diagnosed with a brain injury stemming from the chronic inhalation of
carbon monoxide. Due to the injuries to her health and home, appellant contracted with
1
Clark Heating and Cooling, Inc. to remove and replace the furnace.
{¶ 4} On January 15, 2010, appellant commenced this personal injury and property
1. Clark Heating and Cooling, Inc. is not a party to this appeal.
-2-
Clermont CA2012-03-026
damage action against appellees. In an amended complaint, appellant claims that Rusk
negligently installed the furnace in 2004 and that Rusk, Apollo, and Tribble (together,
"appellees") negligently serviced the furnace for the next four years. As a direct result of
these acts of negligence, appellant claims she was exposed to dangerous levels of carbon
monoxide and other toxins that resulted in serious and permanent injury to her brain.
Appellant further claims that the negligence of appellees led to the "puff back" in the furnace
which caused property damage to her home.
{¶ 5} Several motions were subsequently filed by the parties, including cross-motions
for summary judgment and motions in limine seeking to exclude the testimony of appellant's
expert witness, Michael Mariscalco, Professional Engineer (P.E.). Specifically, Rusk and
Tribble asserted that Mariscalco's opinion did not comply with Evid.R. 702 and the standard
set forth by the United States Supreme Court in Daubert v. Merrell Dow Pharmaceuticals,
Inc., 509 U.S. 579, 113 S.Ct. 2786 (1993). Rusk and Tribble also contended that, without the
testimony of Mariscalco, appellant could not demonstrate that her injuries were caused by the
furnace and, therefore, Rusk and Tribble were entitled to summary judgment. Apollo filed a
similar motion for summary judgment asserting that it was entitled to judgment as a matter of
law.
{¶ 6} A hearing was held on January 20 and 30, 2012 on several Daubert issues
including the admissibility of Mariscalco's expert report and testimony. In both his report and
testimony, Mariscalco opined that insufficient combustion air, caused by the lack of a
combustion air pipe, caused the furnace to emit toxic levels of carbon monoxide into
appellant's home in a concentration level of 5-20 parts per million ("ppm") from the time the
2
furnace was installed in 2004 until it was removed in 2008. Mariscalco explained that his
2. A combustion air pipe is a pipe through which outside air would be supplied to the furnace to facilitate
combustion of the fuel oil.
-3-
Clermont CA2012-03-026
proffered opinion was based on the theory that carbon monoxide spilled from the barometric
damper of the furnace into appellant's living space due to an inadequate source of
combustion air that created a negative pressure differential in the room where the furnace
was located.
{¶ 7} After the hearing, the trial court concluded that, although Mariscalco's proposed
testimony pertained to issues that were beyond the understanding of lay persons and that he
was suitably qualified to render the opinion, Mariscalco's analysis was not sufficiently reliable
and there was simply too great an analytical gap between Mariscalco's data and his opinion.
The trial court then excluded the testimony and reports of Mariscalco from trial and
determined that, without his expert opinion, appellant could not prove that her injuries were
caused by the emission of carbon monoxide from the furnace. Consequently, the trial court
granted summary judgment in favor of appellees.
{¶ 8} Appellant timely appealed, raising two assignments of error.
{¶ 9} Assignment of Error No. 1:
{¶ 10} THE TRIAL JUDGE ABUSED HIS DISCRETION AND COMMITTED AN
ERROR AT LAW BY IMPOSING AN UNPRECEDENTED STANDARD WHILE
CONCLUDING THAT THE PROPOSED TESTIMONY OF PLAINTIFF-APPELLANT'S
ENGINEERING EXPERT WAS NOT SUFFICIENTLY RELIABLE TO BE ADMISSIBLE
PURSUANT TO EVID.R. 702.
{¶ 11} In her first assignment of error, appellant challenges a number of the trial
court's reasons for excluding Mariscalco's testimony, asserting that the trial court forced an
"unachievable standard for reliability" upon appellant and Mariscalco.
{¶ 12} "A trial court's decision on whether to admit or exclude expert testimony will not
be reversed absent an abuse of discretion." Herzner v. Fischer Attached Homes, Ltd., 12th
Dist. No. CA2007-08-090, 2008-Ohio-2261, ¶ 7, citing State v. Jones, 90 Ohio St.3d 403,
-4-
Clermont CA2012-03-026
414. "An abuse of discretion connotes an arbitrary, unreasonable, or unconscionable
decision by the trial court." Id., citing Blakemore v. Blakemore, 5 Ohio St.3d 217, 219 (1983).
When applying the abuse of discretion standard, this court may not substitute its judgment
for that of the trial court. Pons v. Ohio State Med. Bd., 66 Ohio St.3d 619, 621 (1993).
{¶ 13} It is undisputed that Mariscalco's testimony related to matters beyond the
knowledge or experience of laypersons and that Mariscalco qualified as an engineering
expert. Evid.R. 702(A) and (B). Therefore, at issue is the reliability of Mariscalco's testimony
and the underlying calculations he made in support of his expert opinion. See Evid.R.
702(C).
{¶ 14} Evid.R. 702(C) provides that a witness may testify as an expert if:
The witness' testimony is based on reliable scientific, technical,
or other specialized information. To the extent that the testimony
reports the result of a procedure, test, or experiment, the
testimony is reliable only if all of the following apply:
The theory upon which the procedure, test or experiment is
based is objectively verifiable or is validly derived from widely
accepted knowledge, fact or principles;
The design of the procedure, test or experience reliably
implements the theory;
The particular procedure, test or experiment was conducted in a
way that will yield an accurate result.
{¶ 15} "In determining whether an expert's opinions are reliable under Evid.R. 702(C),
our inquiry focuses upon whether the principles and methods the expert employed to reach
his opinion are reliable, rather than whether the conclusions are correct." State Farm Fire &
Cas. Co. v. Holland, 12th Dist. No. CA2007-08-025, 2008-Ohio-4436, ¶ 21, citing Miller v.
Bike Athletic Co., 80 Ohio St.3d 607, 611, 1998-Ohio-178. The trial court, "as part of its
gatekeeping function, must assess both the relevance of the expert's testimony and the
reliability of the testimony prior to admitting such testimony into evidence." State v. Widmer,
-5-
Clermont CA2012-03-026
12th Dist. No. CA2011-03-027, 2012-Ohio-4342, ¶ 67, citing Terry v. Caputo, 115 Ohio St.3d
351, 2007-Ohio-5023, ¶ 24; Miller at 611.
{¶ 16} "In evaluating the reliability of scientific evidence, several factors are to be
considered: (1) whether the theory or technique has been tested, (2) whether it has been
subjected to peer review, (3) whether there is a known or potential rate of error, and (4)
whether the methodology has gained general acceptance." Miller at 611, citing Daubert 509
U.S. at 595.3 Moreover, a court may conclude that there is "simply too great an analytical
gap between the data and the opinion proffered." Valentine v. Conrad, 110 Ohio St.3d 42,
2006-Ohio-3561, ¶ 18.
{¶ 17} In this case, appellant sought to introduce the testimony and report of
Mariscalco to demonstrate that the furnace was the origin of the carbon monoxide which
poisoned her. At the hearing, Mariscalco provided his educational background and training,
and then explained how he reached his opinion that, due to a lack of combustion air, the
furnace emitted carbon monoxide in the concentration level of 5-20 ppm which spread into
the living space of appellant's home. Mariscalco stated that he used a formula from the
National Fire Protection Association's Standard 69 (NFPA 69) and a 1961 study performed
by the National Research Council of Canada (the Canadian Study) that was published by the
4
American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).
From the NFPA 69, which governs the use and control of flammable and combustible gasses
to prevent explosive atmospheres, Mariscalco took the formula in order to determine the
carbon monoxide concentration that would have filtered through appellant's
3. Appellant's argument that Ohio has not adopted the principles of Daubert is without merit. See Miller, 80 Ohio
St.3d at 611; Terry v. Caputo, 115 Ohio St.3d 351, 2007-Ohio-5023, ¶ 24; Widmer, 2012-Ohio-4342 at ¶ 67.
4. The parties' expert witnesses agreed that the NFPA and ASHRAE are generally accepted authorities in the
field of heating, refrigerating, and air conditioning.

Clermont CA2012-03-026
home while the furnace was running.5
{¶ 18} Mariscalco then explained that, in determining the value of "G," the flue gas
leakage rate (of gas leaking from the furnace), Mariscalco performed no testing,
experimentation, or measurements on the furnace or appellant's home. Rather, Mariscalco
based the value of "G" on the 1961 Canadian Study, stating that the home in the Canadian
Study and appellant's home were similar in size. A copy of the NFPA 69 and the Canadian
Study were not admitted into evidence during the hearing.
{¶ 19} Mariscalco also testified that, instead of performing or relying upon a tracer gas
study to determine the value of "Q," the estimated outside infiltration rate into appellant's
house, Mariscalco simply used a "wide range" of infiltration rates to determine his
calculations. Mariscalco admitted that the generally accepted authorities in the field heating,
refrigerating, and air conditioning state that the only way to properly determine the air
infiltration rate into a home is to perform a tracer gas study, but Mariscalco stated that this
was unnecessary because, by using a wide range of air infiltration rates for "Q," he was "able
to cover all the bases predictably anyway." (Emphasis added.)
{¶ 20} Furthermore, Mariscalco testified that he believed the carbon monoxide was
specifically leaking from the barometric damper of the furnace and into appellant's home.
However, after the furnace was removed from appellant's home, but before Mariscalco—or
any other expert—was able to view the barometric damper, the damper disappeared.
Mariscalco testified that he was only able to view the damper through photographs but that
(k*G*V)t
5. The formula Mariscalco used was: CO(t)=(G/(Q))*(1-c )*1,000,000*Cfg
where: CO(t) = carbon monoxide concentration
G = Flue gas leakage into space, CFM (cubic feet per minute)
Q = Estimated outside infiltration rate into house, CFM (cubic feet per minute)
k = Mixing coefficient
V = Volume of residence, cubic feet
t = Time in minutes
Cfg = Concentration of carbon monoxide in flue gas
Neither the record nor the briefs explain the meaning of the variable "c" as it is used in the equation.
-7-
Clermont CA2012-03-026
he did not believe an examination of the actual damper would change his opinion because
his calculation of the carbon monoxide concentration leaking from the furnace was based
upon his knowledge of systems and "what would be typically considered for leakage types of
areas." (Emphasis added.)
{¶ 21} Mariscalco also admitted at the hearing that he had performed no tests on the
furnace and only one test on appellant's home. Mariscalco measured the volume of
appellant's home in order to determine "V" in his formula. Otherwise, Mariscalco did not
perform, and was unaware of any other person performing, a test on the furnace to
determine if it did, in fact, emit carbon monoxide while in operation. Mariscalco conceded
that, although the furnace was not in working order at the time he examined the furnace, it
could have been put into working order except for the missing barometric damper.
{¶ 22} Appellant takes issue with the following four findings made by the trial court: (1)
the Canadian Study was scientifically unreliable, as a copy of the Study was not provided to
the trial court, (2) Mariscalco performed only one test on appellant's home and no tests on
the actual furnace in order to ensure the reliability of his calculations, (3) Mariscalco's final
report stated that his opinion was formed using "conservative assumptions of furnace
leakage and accumulation" rather than actual testing, and (4) there was no evidence that
Mariscalco's methodology of using a series of mathematical calculations including
6
"conservative assumptions" satisfied any of the factors outlined in Daubert.
Absence of the Canadian Study
{¶ 23} Appellant first argues that the trial court erred in finding that, because it was
6. Appellant contends that the trial court erred in relying on Mariscalco's report filed October 30, 2010 (labeled
as "Final Report") instead of Mariscalco's later report filed December 2, 2011 (labeled as "Supplemental
Report"). However, the record clearly shows that the December 2, 2011 report was simply a supplementary
report to a test performed by another expert witness. In fact, Mariscalco points out in the "Supplementary
Report" that his previous conclusions and opinions contained in his October 30, 2010 Final Report are not altered
by the supplement. Thus, the trial court did not err in relying on Mariscalco's October 30, 2010 Final Report.
-8-
Clermont CA2012-03-026
unable to review it, the Canadian Study was scientifically unreliable.7 Appellant also argues
that she was unaware that the Canadian Study was not before the trial court or that the trial
court wished to "scrutinize" the Study.
{¶ 24} "Experts often base their opinions on data and research from within their field of
study." Valentine, 2006-Ohio-3561 at ¶ 18. Yet, "Evid.R. 702(C) requires not only that those
underlying resources are scientifically valid, but also that they support the opinion." Id."Although scientists certainly may draw inferences from a body of work, trial courts must
ensure that any such extrapolation accords with scientific principles and methods." Id. To
the extent that doing so is necessary to avoid making an unreasonable, arbitrary, or
unconscionable decision, a trial court is obliged to apprise itself of the details of resources
relied upon by the experts. See id. at ¶ 20.
{¶ 25} In this case, the trial court was prevented from apprising itself of the details of
the Canadian Study because the document was not provided to the trial court. Thus, the trial
court was unable to determine whether the methodology behind the Canadian Study had
been generally accepted by the scientific community and whether it was a reliable approach
in determining the emission and flow of carbon monoxide in a home. See generally, Finley v.
First Realty Property Mgt. Ltd., 185 Ohio App.3d 386, 2009-Ohio-6797, ¶ 19 (9th Dist.).
Furthermore, without being able to evaluate the Canadian Study, the trial court was unable to
determine whether the house subject to the Study was substantially similar to appellant's
home. Without this determination, the trial court could not say that the mathematical figure
taken from the Canadian Study and used by Mariscalco to determine "G," the flue gas
leakage rate, was a reasonable and scientifically reliable use of the Canadian Study.
7. The Canadian Study was a study of draft conditions caused in the wintertime by the operation of a fuel oil
furnace. Mariscalco sought to use the Study to prove that the emission of carbon monoxide from the furnace
and into the living space of appellant's home would be in the concentration range of 5-20 ppm.
-9-
Clermont CA2012-03-026
{¶ 26} Furthermore, Evid.R. 703 provides that the "facts or data in the particular case
upon which an expert bases an opinion or inference may be those perceived by the expert or
admitted into evidence at the hearing." In this case, the data relied upon by Mariscalco from
the Canadian Study to determine "G" was not something that Mariscalco "perceived" from his
own testing, observations, or experimentation but, instead, something that should have been
admitted into evidence at the hearing.
{¶ 27} Appellant contends that she had no duty to supply the trial court with a copy of
the Canadian Study, had no reason to believe that the trial court desired to "scrutinize" the
study, and believed that Rusk had attached a copy of the study to Mariscalco's deposition
transcript when it was submitted to the trial court. However, the party offering the expert
opinion and testimony bears the burden of proof in establishing its admissibility. Daubert at
592 fn. 10; Knotts v. Black and Decker, 204 F.Supp.2d 1029, 1038 (N.D.Ohio 2002); Mohney
v. U.S. Hockey, Inc., 300 F.Supp.2d 556, 564 (N.D.Ohio 2004). Though appellant asserts
that appellees should not benefit from their failure to provide Mariscalco's deposition with
attached exhibits, appellant provides no reason why she could not and did not submit a copy
of the Canadian Study to the trial court during the hearing, during the discovery phase of the
case, or as an attachment to a motion in this case. The fact that appellees may have erred in
not submitting the exhibits with the deposition does not relieve appellant of her burden to
supply evidence to the court to establish the reliability and admissibility of expert testimony.
{¶ 28} Therefore, as the Canadian Study was not provided to the trial court for
examination, there was no evidence that the mathematical figures Mariscalco garnered from
the Study had any reasonable, analytical relationship to the emission of carbon monoxide
from the furnace in appellant's home. Furthermore, although the Canadian Study was
published by ASHRAE, an authority in the field of heating, refrigerating, and air conditioning,
there was no evidence that the Canadian Study, itself, had been tested, peer reviewed, or
- 10 -
Clermont CA2012-03-026
had a known or potential rate of error. Simply put, there was no foundation for the scientific
reliability of the Canadian Study and why the mathematical figures relied upon in that study
involving that house could reasonably be applied to appellant's home and Mariscalco's
calculation.
{¶ 29} Based upon the foregoing, we cannot find that the trial court abused its
discretion in determining that, without being able to review the Canadian Study, the Study, as
used by Mariscalco as an underlying source for his opinion, was scientifically unreliable.
Mariscalco's Lack of Testing and Reliance on Assumptions
{¶ 30} Appellant next takes issue with the trial court's finding that Mariscalco failed to
perform significant testing on appellant's home and furnace while making assumptions
regarding the air infiltration rate ("Q") and the flue leakage rate ("G").
{¶ 31} "Expert testimony may not be based on mere speculation." Rose v. Truck
Centers, Inc., 611 F.Supp.2d 745, 750 (N.D.Ohio 2009), citing Daubert, 509 U.S. at 590.
Although an expert is not required to perform independent tests or experiments in forming his
opinion, the absence of such scientific tests or experiments may demonstrate an absence of
a reliable methodology. See Evid.R. 702; Botnick v. Zimmer, Inc., 484 F.Supp.2d 715, 720
(N.D.Ohio 2007) (absence of studies, tests, or experiments performed by expert to validate
expert's opinion fails to satisfy the reliability standard outlined in Daubert).
{¶ 32} Here, Mariscalco openly stated at the hearing and during his deposition that,
beyond his test to determine the volume of appellant's home, he performed no tests on the
furnace or appellant's residence. Further, Mariscalco admitted that the generally accepted
way of determining the air infiltration rate ("Q") into a home is to perform a tracer gas study.
Yet, Mariscalco chose not to perform such a study. Instead, Mariscalco used a range of
infiltration rates to "predict" the amount of carbon monoxide emitted from the furnace and
entering appellant's living space while the furnace was running. Furthermore, as was
- 11 -
Clermont CA2012-03-026
discussed above, Mariscalco relied upon what the trial court could only conclude was an
unreliable study in order to determine "G." Thus, based upon our review of the record, the
trial court did not err in finding that Mariscalco failed to perform any significant tests on the
furnace and that his opinion and calculations were based upon assumptions.
Application of Daubert
{¶ 33} Appellant contends that the trial court erred in holding that there was no
evidence that Mariscalco's methodology of using a series of mathematical calculations
including "conservative assumptions" had ever been tested by any other qualified expert, had
been subject to peer review, contained a known or potential rate of error, or gained general
acceptance in the professional, scientific, technical, or engineering communities. In making
this argument, appellant also asserts that the trial court has created a new standard by
requiring that an expert satisfy all of the Daubert factors before being permitted to testify.
{¶ 34} However, in reviewing the trial court's decision, we cannot find support for this
argument. The trial court simply stated that:
[appellant] has not established that Mariscalco's methodology of
using just a series of mathematical calculations using
'conservative assumptions of furnace leakage and accumulation,'
and undisclosed 'background data,' has:
(1) been tested by any other qualified expert;
(2) been subject to peer review;
(3) a known or potential rate of error;
(4) gained general acceptance in the professional, scientific,
technical or engineering communities.
The trial court's failure to place an "and" or "or" before the third and fourth factors of Daubert
does not lead to the conclusion that the trial court was outlining a new and stricter standard.
{¶ 35} Appellant goes on to argue that the trial court erred in finding that Mariscalco's
expert opinion failed to meet any of the Daubert factors. As noted above, to determine the
- 12 -
Clermont CA2012-03-026
reliability of testimony, the trial court may consider one or more of the factors outlined in
Daubert: (1) whether the theory or scientific technique has been tested, (2) whether the
theory or technique has been subject to peer review or publication, (3) whether the method
has a known or potential rate of error, and (4) whether the theory has gained general
acceptance in the scientific community. Daubert 509 U.S. at 593-594. "The focus is not on
the substance of the expert's conclusions, but on how the expert arrived at his conclusions."
Herzner at ¶ 9, citing Valentine, 2006-Ohio-3561, at ¶ 16.
{¶ 36} In this case, all parties agree that the NFPA and ASHRAE are the authoritative
organizations and manuals in the requisite field. Moreover, it does not appear that the trial
court took issue with Mariscalco's reliance upon the formula published in the NFPA 69 or
ASHRAE. The trial court did, however, take issue with Mariscalco's use of the Canadian
Study to calculate the flue leakage rate of appellant's home without any evidence that the
Canadian Study was a scientifically reliable method of testing the emission of carbon
monoxide from a furnace or that the house referenced in the Canadian Study was
substantially similar to appellant's home in size, composition, and construction.8
{¶ 37} In Herzner v. Fisher, 2008-Ohio-2261 at ¶ 11, this court addressed the
admissibility of an expert's opinion that a plaintiff suffered illness due to her exposure to toxic
mold in her condominium unit. The expert relied upon tests conducted on the condominium
three months after the plaintiff had vacated the unit. Although the test showed that mold
spores were present in the unit, there was no evidence that the mold spores detected were
present while the plaintiff was living in the unit or caused the sort of illness from which the
plaintiff suffered. Id. Based upon this evidence, the trial court concluded that "there was too
great a gap between the data and [the expert's] opinion[.]" Id. In reviewing the trial court's
8. The Canadian Study was conducted in 1961 while appellant's home was not even built until 1965.
- 13 -
Clermont CA2012-03-026
ruling, this court concluded that the trial court thoroughly "exposed numerous faults in the
principles and methods utilized by [the expert] to draw his conclusions" and, therefore, did
not abuse its discretion in excluding the expert's testimony. Id. at ¶ 15.
{¶ 38} Just as in Herzner, Mariscalco's opinion cannot be relied upon to show that
carbon monoxide was present in appellant's home during the time the furnace was in
operation from 2004 to 2008. In Herzner, there was a lack of evidence that toxins were
actually present in the condominium while the plaintiff was in residence. Similarly, in this
case, there is a lack of evidence and testing on the part of Mariscalco to demonstrate that
carbon monoxide was (1) ever actually emitted from the furnace in the concentration level of
5-20 ppm, and (2) that any carbon monoxide emitted from the furnace entered the living
space of appellant's home.
{¶ 39} Due to Mariscalco's reliance on the Canadian Study, lack of testing, and
reliance upon assumptions regarding the air infiltration rate and the way air and carbon
monoxide would "typically" or "predictably" flow through appellant's home, the trial court
determined that there was simply too great a gap between the data used by Mariscalco and
his expert opinion to satisfy the strictures of Evid.R. 702(C). Based upon our review of the
record, we find that the trial court did not abuse its discretion in making such a determination.
{¶ 40} Accordingly, appellant's first assignment of error is overruled.
{¶ 41} Assignment of Error No. 2:
{¶ 42} THE TRIAL JUDGE ERRED, AS A MATTER OF LAW, BY GRANTING
SUMMARY JUDGMENT IN FAVOR OF DEFENDANT-APPELLEES [SIC].
{¶ 43} In her second assignment of error, appellant contends the trial court erred in
granting summary judgment in favor of appellees. Specifically, appellant argues that, even
without the testimony of Mariscalco, sufficient evidence exists as to create a genuine issue of
material fact that appellant suffered permanent brain damage due to the negligence of
- 14 -
Clermont CA2012-03-026
appellees and that appellant's property was damaged due to the "puff back" which occurred
in the furnace, also caused by appellees' negligence.
{¶ 44} This court reviews a trial court’s decision on summary judgment under a de
novo standard of review. Harold v. Nationwide Mut. Ins. Co., 12th Dist. No. CA2007-01-013,
2008-Ohio-347, ¶ 11. Summary judgment is proper when: (1) there is no genuine issue of
material fact, (2) the moving party is entitled to judgment as a matter of law, and (3)
reasonable minds can only come to a conclusion adverse to the party against whom the
motion is made, construing the evidence most strongly in that party's favor. Civ.R. 56(C).
The party requesting summary judgment bears the initial burden of informing the court of the
basis for the motion and identifying those portions of the record that demonstrate the
absence of a genuine issue of material fact as to the essential elements of the nonmoving
party's claims. Dresher v. Burt, 75 Ohio St.3d 280, 293 (1996). Once a party moving for
summary judgment has satisfied its initial burden, the nonmoving party has the reciprocal
burden to set forth specific facts showing that genuine issues remain. Id.; Civ.R. 56(E).
Summary judgment is proper if the party opposing the motion fails to set forth such facts. Id.Personal Injury
{¶ 45} Appellant first contends that, even without the testimony of Mariscalco, genuine
issues of material fact exist as to whether appellant suffered permanent brain damage due to
the negligent conduct of appellees. Specifically, appellant points to the opinions of her
remaining expert witnesses: Robert Thomson, a professional engineer, Dr. Dennis
Helffenstein, a clinical psychologist and rehabilitation counselor, and Dr. S. Gregory Hipskind,
a neurologist.9 Appellees, on the other hand, contend that the opinions of appellant's experts
fail to provide sufficient opinions as to specific causation.
9. Neither Rusk, Apollo, nor Tribble sought to exclude the expert testimony of these individuals.

{¶ 46} "To withstand summary judgment in a negligence action, a plaintiff must
present evidence that the defendant owed the plaintiff a duty, that the duty was breached,
and that the breach was the proximate cause of the plaintiff's damages." Kerns v. Hobart
Brothers Co., 2nd Dist. No. 2007CA32, 2008-Ohio-2242, ¶ 124; Roberts v. RMB Ents., Inc,
197 Ohio App.3d 435, 2011-Ohio-6223, ¶ 31 (12th Dist.). To prove that a toxic substance,
such as carbon monoxide, caused the plaintiff's medical condition, the plaintiff must establish
"(1) that the toxin is capable of causing the medical condition and ailment (general
causation), and (2) that the toxic substance in fact caused the claimant's medical condition
(specific causation)." Terry v. Caputo, 115 Ohio St.3d 351, 2007-Ohio-5023, paragraph one
of the syllabus. Specifically, the plaintiff must show that she was exposed to a toxic
substance and that the level of exposure was sufficient to induce the complained-of medical
condition, commonly known as "dose-response relationship." Valentine v. PPG Industries,
Inc., 158 Ohio App.3d 615, 2004-Ohio-4521, ¶ 17, fn. 1 (4th Dist.), affirmed by Valentine v.
Conrad, 110 Ohio St.3d 42, 2006-Ohio-3561. See also Wiley, Expert Witness Update: New
Developments in Personal Injury Litigation, Section 1.04, at 18-19, and Section 1.05[C], at 28
("the dose makes the poison") (2000). "The mere coincidence of exposure and the
appearance of a disease is never sufficient to prove causation in an individual instance." Id.
at ¶ 47, citing Susan R. Poulter, Science and Toxic Torts: Is There a Rational Solution to the
Problem of Causation?, 7 High Tech.L.J. 189 at 216 (1992); Kerns at ¶ 96.
{¶ 47} "Establishing general causation and specific causation in cases involving
exposure to mold or other toxic substances involves a scientific inquiry, and thus causation
must be established by testimony of a medical expert." Terry, 2007-Ohio-5023 at paragraph
two of the syllabus. Without this expert testimony to establish both general and specific
causation, "a claimant cannot establish a prima facie case of exposure to mold or other toxic
- 16 -
Clermont CA2012-03-026
substances." Id. at paragraph three of the syllabus.
{¶ 48} The parties do not dispute that the inhalation of carbon monoxide is capable of
causing brain damage. Thus, the issue of general causation is established and the
remaining issue is whether specific causation can be demonstrated by appellant. According
to appellees, there is a lack of evidence establishing that appellant's brain damage was
caused by exposure to carbon monoxide which was caused by the furnace as opposed to
other possible causes including a blocked chimney. This court shall begin by reviewing the
reports and assessments of appellant's remaining experts.
{¶ 49} On May 17, 2010, Thomson gave his report regarding the furnace and
appellant's home. In formulating his opinion, Thomson stated that he visited and inspected
the furnace after it had been removed from appellant's home, that he visited and inspected
appellant's home, that he took photographs of the home and furnace, and that he interviewed
appellant. Thomson concluded that, as the furnace lacked a proper amount of combustion
air, the fuel inside the furnace did not burn adequately and the unburned fuel caused carbon
monoxide to exhaust from the furnace. This carbon monoxide was "most likely" drawn into
the distribution system of the house and entered the living space of the home, which could
10
have resulted in carbon monoxide poisoning to residents of the home. Thomson concluded
that the distribution of carbon monoxide into the living space of a residence could result in
"poisoning for the occupants." Yet, Thomson never opined as to the amount of carbon
monoxide that could, or did, enter the living space of appellant's home or how often the
distribution of carbon monoxide occurred.11
10. Although not raised by the parties, this court questions whether Thomson's opinion is competently
expressed in terms of probability or reasonable scientific certainty and not a lesser degree of certainty. See
Schneble v. Stark, 12th Dist. Nos. CA2011-06-063, CA2011-06-064, 2012-Ohio-3031, ¶ 39.
11. Again, appellant takes issue with the trial court's reliance on this May 17, 2010 report, stating that the trial
court "fixated" upon this initial report while "ignoring" Thomson's December 7, 2011 supplemental report.
However, as indicated in Thomson's supplemental report, his initial opinion from the May 17, 2010 report
- 17 -
Clermont CA2012-03-026
{¶ 50} In his neuropsychological evaluation, Dr. Helffenstein bases his opinion, at least
in part, on the May 17, 2010 Engineering Report of Thompson for the conclusion that,
because the furnace in appellant's home had an insufficient source of combustion air, the
furnace emitted carbon monoxide into appellant's home while it was in operation. Thus, Dr.
Helffenstein worked under the assumption that appellant was exposed to carbon monoxide
from 2004 until 2008. Dr. Helffenstein concluded, after performing tests on appellant and
reviewing her medical files, that appellant "experienced a chronic exposure to carbon
monoxide between March 2004 and January 18, 2008." Dr. Helffenstein further found that
appellant "was essentially exposed to carbon monoxide during the time that she was in her
home and the furnace was in operation."
{¶ 51} In his report, Dr. Hipskind states, in the section titled "Patient's
History/Indication for Brain SPECT Evaluation," that appellant was evaluated for carbon
monoxide poisoning "that was caused by an improperly installed furnace in her home." Dr.
Hipskind further states, without providing the basis for these conclusions, that the exposure
occurred "from 2004 to 2008 because a combustion pipe was never installed[,] thus the
furnace released carbon monoxide into [appellant's] house." Dr. Hipskind indicates that,
according to OSHA, "levels of 9 parts per million or above [of carbon monoxide] may be
associated with health risks." He then opined that the exposure level to appellant would have
been at least been between 6-9 ppm based upon "the current science." Dr. Hipskind
concluded that, based upon current understanding of exposure levels to carbon monoxide,
as well as appellant's high-definition brain SPECT imaging, appellant's condition is consistent
with a chronic low grade exposure to carbon monoxide.
{¶ 52} The reports and affidavits of Drs. Helffstein and Hipskind are premised upon
remained "unchanged" by the supplemental report. Thus, the trial court was not wrong in reviewing and
discussing Thomson's May 17, 2010 report.

Clermont CA2012-03-026
Thomson's assumption that, due to a lack of combustion air, carbon monoxide was "most
likely" distributed into the living space of appellant's home and that this distribution could
result in "poisoning" to appellant. However, the fact that carbon monoxide was produced by
the furnace and "most likely" entered appellant's living space does not warrant the conclusion
that appellant inhaled said carbon monoxide at toxic levels, thereby causing her permanent
brain damage. Furthermore, although Dr. Hipskind states that "levels of 9 parts per million or
above [of carbon monoxide] may be associated with health risks," there is no indication in the
record—beyond Mariscalco's now excluded testimony—that the level of carbon monoxide in
appellant's living space reached 9 ppm. Simply because appellant suffers from the effects of
carbon monoxide poisoning does not necessarily equate to a finding that carbon monoxide,
at a toxic level, was emitted from the furnace or was distributed through her home. As stated
above, there was no testing performed in the home which showed any level of carbon
monoxide existing in the living space of appellant's home between 2004 and 2008.
{¶ 53} Therefore, based upon our review of the record in this case, we find that
appellant has failed to establish that genuine issues of material fact remain as to the element
of specific causation. Consequently, the trial court did not err in granting summary judgment
to appellees on appellant's personal injury claims, as appellees are entitled to judgment as a
matter of law.
Property Damage
{¶ 54} Appellees also moved for, and were granted, summary judgment as to
appellant's property damage claims. However, although generally stating that the trial court
erred in granting summary judgment, appellant fails to address in her brief the grant of
summary judgment with respect to the property damage claims. Therefore, we need not
review this aspect of the trial court's decision. Appellant's failure to raise an argument in her
brief constitutes a waiver of the argument on appeal. Radvansky v. City of Olmsted Falls,
- 19 -
Clermont CA2012-03-026
395 F.3d 291, 310 (6th Cir.2005).
{¶ 55} For the reasons set forth above, appellant's second assignment of error is
overruled.
