Before: COLE, NALBANDIAN, and READLER, Circuit Judges.
COLE, Circuit Judge. Angelo Thompson suffered severe burns due to a generator fire on
the roof of his residence. To recover damages from the incident, Thompson sued various parties,
including the generator manufacturer and seller, under a theory of products liability. The
defendants relevant on appeal, Techtronic Industries North American (“Techtronic”) and One
World Technologies, Inc. (“One World”), moved for summary judgment, disclaiming liability due
to Thompson’s alleged impairment and unforeseeable misuse. The district court granted summary
judgment on both grounds. We affirm.
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
I. BACKGROUND
A. Facts
Angelo Thompson resides in an apartment complex that often uses a generator as a source
of power when the building owner is unable to pay for electricity. This case concerns one such
generator—a Ryobi gasoline-powered generator designed by One World. Thompson’s landlord
purchased the generator for use at Thompson’s building on or about September 16, 2016, and it
was installed on the roof that same day. The power went out in Thompson’s building on September
25, 2016. Another tenant, Brook Banham, tried to restart the generator. Around 9:30 p.m.,
Banham told Thompson that he was unable to start the Ryobi generator, so Thompson went to
help.
Thompson testified that he had read the operator’s manual for a prior generator and at least
some of the Ryobi generator operator’s manual, and that he knew the risks of gasoline. Thompson
was unable to start the generator and decided to check the generator’s gas level. The generator did
not have an external gas gauge, so he removed the gas cap, tilted the generator using the upright
handle, and shined his flashlight inside. After seeing there was gas in the generator, there was an
“explosion,” and Thompson’s pant legs caught on fire—the gas “was all over [him], and [he] was
all on fire.” (Pl.’s Dep., R. 60, Ex. 2, PageID 961–62, 966–67.)
Banham and his wife came to the roof to help after hearing Thompson’s screams, where
they then saw Thompson “on the ground, kind of rolling around, trying to pat the flames on his
legs and shoes.” (Brook Banham Dep., R. 73, Ex. 4, PageID 2416.) Banham used a fire
extinguisher to put out the remaining flames. Thompson refused Banham’s offer to call an
ambulance, but Banham later drove him to the hospital.

Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
The explosion resulted in second and third degree burns to Thompson’s lower legs,
covering 18 or 19% of his body. Thompson underwent multiple skin-graft surgeries and has
ongoing physical and emotional pain and difficulties resulting from the incident. At the hospital,
tests from 1:56 a.m.—approximately four hours after the fire—revealed Thompson had a blood
alcohol concentration (“BAC”) of 0.046 and his urine drug screen was positive for cannabinoids,
cocaine metabolite, and opiates.
The defendants’ medical toxicologist expert, Dr. Kirk Charles Mills, interpreted
Thompson’s blood and urine samples from the hospital. Specifically, Dr. Mills applied a scientific
technique called “retrograde extrapolation” to estimate Thompson’s earlier BAC based on his later
BAC, factoring in the average male population’s alcohol metabolization rate. (Mills Rep., R. 60,
Ex. 7, PageID 1020–21.) He calculated that “Thompson’s extrapolated BAC at the time of the
accident was most likely between 0.086 and 0.126, with an average BAC of 0.106 at [the time of
the accident.]” Dr. Mills concluded that a BAC in his estimated range is “more than sufficient to
cause alcohol impairment” and that “more likely than not, Mr. Thompson’s alcohol impairment
was a major contributor to the accident,” which occurred as a result of Thompson “remov[ing] the
generator gas cap, tilt[ing] the generator forward, spilling gasoline on himself and the generator,
[and] causing ignition of the gasoline[.]” He stated that Thompson’s injuries from this ignition
were “entirely preventable” had he not operated the generator while under the influence of alcohol.
Dr. Mills noted that Thompson understood the operator’s manual’s warning to “not operate
generator when you are . . . under the influence of drugs, alcohol, or medication” to mean “that if
you are [sic] impaired in any way [sic] you could make a deadly mistake.”
Dr. Mills also discussed Thompson’s drug screen, which was positive for cannabinoids,
cocaine metabolite, and opiates. While Thompson did not appear to be impaired by drugs at the
-3-
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
hospital, Dr. Mills noted that the time delay between the accident and his evaluation was long
enough for him to not show signs of drug impairment even if he had consumed such substances.
But positive urine tests for such substances may indicate use prior to the day of the incident, and
the positive opioids result could have been from an IV at the hospital. So, Dr. Mills ultimately
based his conclusion on Thompson’s impairment due to alcohol, not drugs.
As to the generator itself, the defendants submitted an evaluation by a mechanical engineer
and certified fire and explosion investigator, Dennis Scardino. Scardino concluded that Thompson
introduced the ignition source, that Thompson’s conduct caused the gas spill and the fire, and that,
ultimately, the generator’s design “was not defective and was not a cause of this fire.” (Scardino
Rep., R. 60, Ex. 9, PageID 1076.) As to his conclusion about the generator not being defective,
Scardino reported that the “fuel [level indicator] cap feature is not necessary for the safe operation
of a generator” and that “deliberate removal of the generator’s fuel fill cap with the subsequent
deliberate movement (e.g., tilting . . . ) of the generator would not be a reasonable action[.]”
Scardino also noted Thompson’s knowledge of the hazards of gasoline and his review of the
generator’s operator’s manual and the “on-product decals and instructions” prior to the incident,
which Scardino said were “adequate and sufficient for the safe operation of the generator.”
In addition, the defendants submitted an affidavit from David Anderson, a product safety
engineer at Techtronic who is familiar with or has personal knowledge of the design, use,
operation, and associated standards of the generator at issue. (Anderson Aff., R. 60, Ex. 4, PageID
972.) Anderson testified that Thompson’s conduct constituted a misuse of the generator, and that
such misuse is unforeseeable. As to the tipping, Thompson alleged the generator was defective by
having an upright “hand truck” style handle and by not having an external gas gauge or forward
stabilizing legs. (Compl., R. 1, PageID 22–25.) Anderson claimed the manufacturer has “no
-4-
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
record of any claim or suit of injury that the Ryobi generator . . . was somehow defective” in the
ways Thompson alleged. He further stated that operating the generator the way Thompson did—
knowing the hazards of gasoline, as described in the generator’s manual—is “inconsistent with
actions of a reasonably prudent consumer.” As to intoxication, he pointed to the manual’s “explicit
warning . . . about not attempting to operate the generator when under the influence of alcohol” as
evidence that doing so, especially knowing the risks, would be an unforeseeable misuse.
B. Procedural History
Thompson filed a product liability suit alleging (1) negligent design and (2) breach of
implied warranties of fitness for a particular purpose and merchantability. The suit was originally
filed in state court against Ryobi Limited, Ryobi Tools, Techtronic, One World, and Home Depot.
Some of the original defendants removed the lawsuit to federal court based on diversity
jurisdiction. Ryobi Limited, Ryobi Tools, and Home Depot were dismissed at various points
during the litigation, so the relevant defendants here are Techtronic and One World
(“defendants”)—Techtronic only as the parent company of One World, who designed the
generator at issue.
Discovery commenced, and the defendants sought to preclude Thompson from calling four
proposed experts as witnesses, as well as from calling any treating physician for their testimony.
A magistrate judge granted the motion to exclude as to two experts and denied as to two experts,
and limited what Thompson’s treating physicians could testify about. The defendants timely
objected. The defendants simultaneously sought summary judgment on five grounds, including
two relevant on appeal: impairment and unforeseeable misuse.
The district court granted summary judgment on both grounds, finding that Thompson
failed to present arguments or evidence sufficient to create a genuine issue of material fact. district
-5-
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
court also denied the defendants’ motion to strike Thompson’s multiple briefs in response to the
defendants’ motion for summary judgment—two of which were untimely—and denied the
defendants’ objections to the magistrate judge’s order as moot.
On appeal, Thompson challenges both grounds of the district court’s grant of summary
judgment in favor of the defendants.
II. ANALYSIS
A. Legal Standard
We review the district court’s grant of summary judgment de novo, viewing all the
evidence and inferences in the light most favorable to the nonmoving party. Campbell v. Grand
Trunk W. R.R. Co., 238 F.3d 772, 775 (6th Cir. 2001).
Rule 56 requires summary judgment against a party who fails to establish the existence of
an element essential to their case on which they would bear the burden of proof at trial. Celotex
Corp. v. Catrett, 477 U.S. 317, 322–23 (1986). Summary judgment employs a burden shifting
framework: if the moving party meets their burden of “demonstrating the absence of a genuine
issue of material fact,” “the nonmoving party must come forward with ‘specific facts showing that
there is a genuine issue for trial.’” Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S.
574, 585 n.10, 587 (1986) (quoting Fed. R. Civ. P. 56(e) (amended 2010)). To satisfy this burden,
the nonmoving party must present a sufficient amount of evidence such that a reasonable juror
could find for them, Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 252 (1986), and must direct
the court to specific facts in the materials in the record to support their argument, Fed. R. Civ. P.
56(c)(1); Celotex, 477 U.S. at 324.

Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
B. Analysis
1. Misuse
“A manufacturer or seller is not liable in a product liability action for harm caused by
misuse of a product unless the misuse was reasonably foreseeable.” Mich. Comp. Laws
§ 600.2947(2) (emphasis added). So, to avoid liability on misuse grounds, we must resolve two
legal questions in favor of the defendants: (1) that there was a misuse of the product, and (2) that
such use was not reasonably foreseeable. See id.
“Misuse” has been statutorily defined by the Michigan legislature as “use of a product in a
materially different manner than the product's intended use,” including “uses contrary to a warning
or instruction . . . and uses other than those for which the product would be considered suitable by
a reasonably prudent person in the same or similar circumstances.” Mich. Comp. Laws
§ 600.2945(e). Though “reasonably foreseeable” has not been as clearly defined, according to the
Michigan Supreme Court, “the crucial inquiry is whether, at the time the product was
manufactured, the manufacturer was aware, or should have been aware, of that misuse,” which
includes “whether that misuse was a common practice, or if foreseeability was inherent in the
product.” Iliades v. Dieffenbacher N. Am. Inc., 915 N.W.2d 338, 344 (Mich. 2018).
As a threshold matter, we define the “misuse” at issue. The district court agreed with the
defendants that Thompson misused the generator by tipping the generator while the cap was off
and by operating it while impaired. On appeal, Thompson “does not challenge a finding of
‘misuse’ under [the statute’s] broad definition,” (Appellant Br. 18 n.6), so we accept the district
court’s characterization and proceed assuming Thompson misused the generator in both of these
ways.
-7-
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
Regardless of whether the defendants assert unforeseeable misuse as a statutory defense or
whether Thompson must prove his misuse was reasonable as part of his prima facie case, the
impact is the same: the underlying product liability action can only move forward to the extent
that the defendants can be held liable, which turns here on whether Thompson unforeseeably
misused the generator.
Thompson is correct that “if ‘misuse’ is ‘foreseeable’ the case may move forward.”
(Appellant Br. 18 n.6.) But at the summary judgment stage, if the moving party presents evidence
in their favor—here, that the misuses were unforeseeable—the nonmoving party must then present
evidence to rebut the moving party’s assertions—here, that the misuses were foreseeable. As
discussed above, the defendants submitted a report from a fire and explosion investigator and an
affidavit from a Techtronic product safety engineer. Both the report and affidavit support a finding
that Thompson’s misuses of the generator were not reasonably foreseeable. Both Scardino and
Anderson concluded that Thompson misused the generator and discussed Thompson’s knowledge
of the relevant safety guidelines, such as the hazards of gasoline and warnings not to operate the
generator under the influence. Scardino focused on the safety of the generator as designed, and
opined that the misuse by tilting was not “inherent” in the product because it was “not . . . a
reasonable action as it would be expected to result in gasoline spillage[.]” Anderson attested that
Thompson’s tilting and use of the generator while under the influence are unintended uses, and
that the defendants were unaware of any uses of the generator in this way. In their motion for
summary judgment, the defendants engaged with the report and affidavit, and directed the court to
this evidence in the record to support that both misuses were unforeseeable.
In response below, Thompson put forth no argument to counter the defendants’ arguments
that neither misuse is foreseeable. Thompson’s response focused only on establishing the elements
-8-
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
of his underlying products liability claim for negligent design, and specifically on proving an
alternative design. But as discussed, in order to succeed on his products liability claim, Thompson
must be able to hold the defendants liable. Even if Thompson properly alleged the other elements
of his products liability claim, if the defendants can prove they are not liable due to Thompson’s
actions, the case does not move forward. At the summary judgment stage, Thompson must proffer
enough evidence that a jury could reasonably find that either misuse was foreseeable. Thompson
failed to do so in his response, and we limit our review to that document on appeal. See Rutland
v. R & R Trailers Inc., No. 21-1181, 2021 WL 4847704, at *2 (6th Cir. 2021) (addressing a
forfeited misuse argument).
Ultimately, because Thompson, as the nonmoving party, did not “come forward with some
probative evidence” that his misuse was foreseeable such that it would be “necessary to resolve
the differences at trial,” summary judgment is appropriate. Boyd v. Ford Motor Co., 948 F.2d 283,
285 (6th Cir. 1991).
2. Impairment
To win on Michigan’s impairment affirmative defense at the summary judgment stage, the
defendants must show that Thompson was “impaired,” as defined in the statute, and that because
of this impairment, Thompson was 50% or more the cause of the accident or event that resulted in
his injury. Mich. Comp. Laws § 600.2955a(1); Harbour v. Corr. Med. Servs., Inc., 702 N.W.2d
671, 674 (Mich. Ct. App. 2005). If an individual is considered “impaired” as it relates to vehicle
operation, that individual is presumed to be “impaired” in the personal injury context. Mich.
Comp. Laws § 600.2955a(2)(b). Per Michigan law, an individual is too impaired to operate a
-9-
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
vehicle if their blood alcohol concentration (BAC) is 0.08 or above.1 Mich. Comp. Laws
§ 257.625(1)(b). So, an individual with a BAC of 0.08 or above is presumed to be impaired in the
personal injury context. If the defendant demonstrates that such a presumption applies, and that
the individual’s impairment was 50% or more the cause of the accident, the burden then shifts to
the plaintiff to prove a genuine dispute of fact on either element. See Campbell, 238 F.3d at 775.
As to impairment, the defendants proffered its expert toxicologist’s opinion that, based on
Thompson’s hospital toxicology records approximately four hours after the incident, Thompson’s
BAC would have been between 0.086 and 0.126, with an average of 0.106, at the time of the
incident. Mills’ report puts Thompson’s BAC over the legal driving limit, which entitles the
defendants to a presumption that Thompson was impaired at the time of the incident. See Mich.
Comp. Laws § 600.2955a(2)(b). In response, Thompson asserted that his decisions to roll himself
or jump to the ground from the roof and call out for help upon landing were conscious, life-saving
choices. This “alertness and presence of mind,” he claimed, “exemplifies contrary indications that
any consumption of alcohol adversely affected [his] alertness and analytical ability[.]” (Pl.’s Resp.
to Defs.’ Mot. Summ. J., R. 72, PageID 2317.) But he does not present any evidence—only
argument—that this was his state of mind at the time of the incident. See Duha v. Agrium, Inc.,
448 F.3d 867, 879 (6th Cir. 2006) (“Arguments in parties’ briefs are not evidence.”). So, the
defendants carried their burden on the first prong of the impairment defense.
As to causation, finding that this BAC is “more than sufficient to cause alcohol
impairment,” Mills opined that such impairment was “more likely than not . . . a major contributor
to the accident” when considering Thompson’s knowledge of both the risk of operating the
1
Michigan increased the impairment presumption BAC to 0.10 in 2021 but, as the conduct occurred in 2016, we agree
with the district court that the 0.08 BAC level should control. See Op. and Order, R. 87, PageID 3032 n.4 (interpreting
Mich. Comp. Laws § 257.625(1)(b)).
- 10 -
Case No. 22-1228, Thompson v. Ryobi Ltd., et al.
generator while impaired and the flammable nature of the gas. Mills concluded the injury was
“entirely preventable” had Thompson not used the generator while impaired, and that doing so is
“consistent with risk-taking behavior due to poor judgment caused by alcohol impairment.” On
this evidence alone, the district court determined there was no dispute of fact on causation—a
conclusion required to grant summary judgment on this ground.
While we agree with the district court that Thompson ultimately failed to present evidence
to rebut the presumption that he was impaired, we withhold judgment on the second element of
the impairment defense. As we grant summary judgment to the defendants regardless, we need
not definitively determine whether the defendants’ evidence constitutes unrebutted evidence that,
because of his impairment, Thompson was 50% or more the cause of the accident.
III. CONCLUSION
For the foregoing reasons, we affirm the district court’s opinion and order.
