    OPINION BY BOWES, J.:                                  FILED JUNE 1, 2018
    James Zimmerman appeals the order granting summary judgment in
    favor of Alexander Andrew, Inc. t/d/b/a FallTech (“FallTech”). We reverse and
    remand for further proceedings consistent with this opinion.
    In April 2008, Mr. Zimmerman went to the home of his friend, Jim
    Shanks, to cut down a dead tree at Mr. Shanks’s request.          When Mr.
    Zimmerman arrived, Mr. Shanks presented him with a FallTech safety harness
    to use during the process. Mr. Shanks had obtained the harness from a mutual
    friend who had purchased it but never used it. For ease of discussion, we
    include from the record a photograph of the harness at issue and a drawing
    from its instruction manual.
    J-S85013-17
    The harness’s packaging included an instruction paper. Mr. Zimmerman
    scanned, but did not thoroughly read, the instructions and noted that the
    harness was intended to hold more than the combined weight of his body and
    the chain saw he intended to use on the tree. There was also a warning label
    on the harness itself, which Mr. Zimmerman saw but did not read completely.
    Mr. Zimmerman, from limited personal experience using a harness in
    construction work and seeing them used on television programs featuring
    people cutting trees, thought the use of the harness was self-explanatory.
    Mr. Shanks helped Mr. Zimmerman into the harness, putting it on
    backwards such that the harness’s back D-ring was on Mr. Zimmerman’s
    chest. Mr. Zimmerman climbed the tree and strapped himself to it, using the
    D-rings on the sides of the harness to bear his weight, rather than anchoring
    himself to a point above his head from the D-ring that the instructions
    indicated was to be on his back. When the wind suddenly began blowing, Mr.
    -2-
    J-S85013-17
    Zimmerman attempted to change position and caused his full weight to be
    borne by the harness. The harness failed, and Mr. Zimmerman fell thirty-five
    feet to the ground. As a result, Mr. Zimmerman suffered a collapsed lung and
    numerous fractured bones, and ultimately required the amputation of his right
    leg below the knee.
    In March 2010, Mr. Zimmerman filed a complaint stating claims of strict
    products liability, negligence, and breach of warranty against FallTech.1
    Specifically, Mr. Zimmerman contended as follows as to strict liability:
    a)     The safety harness was sold with component parts that were
    of insufficient strength and durability;
    b)     The safety harness was designed and manufactured with
    weak and faulty component parts, making it unreasonably
    dangerous;
    c)     The safety harness was distributed and sold with inadequate
    warnings regarding the use and maintenance of it and the
    hazards associated with its proper use; and
    d)     The safety harness was not stable enough for routine and
    regular use.
    Amended Complaint, 6/4/10, at ¶ 22.              Mr. Zimmerman made similar
    allegations regarding his negligence claims, couched in terms of FallTech’s
    failure to use reasonable care. 
    Id. at ¶
    25. Finally, Mr. Zimmerman claimed
    that his injuries were caused by FallTech’s breach of the implied warranty of
    ____________________________________________
    1Mr. Zimmerman also sued electric and gas companies that he claimed should
    have maintained the tree from which he fell. Those counts were dismissed on
    preliminary objections, and Mr. Zimmerman does not challenge their dismissal
    on appeal.

    merchantability. 
    Id. at ¶
    28. FallTech, inter alia, asserted in its new matter
    the affirmative defenses of misuse of the product and comparative negligence.
    Answer and New Matter, 2/22/11, at ¶¶ 39, 46.
    Following discovery, FallTech moved for summary judgment as to all
    claims based upon the manner in which Mr. Zimmerman used the harness.
    Specifically, FallTech contended that the harness was intended for use on
    construction projects by workers trained in how to use it, and Mr.
    Zimmerman’s use of it in a tree without training was misuse, not an intended
    use, and further was not foreseeable.        Motion for Summary Judgment,
    1/19/17, at 3-5. Mr. Zimmerman responded with the expert report of James
    L. Glancey, Ph.D., P.E., who opined that Mr. Zimmerman used the harness for
    a foreseeable application, and that the proximate cause of his injuries was
    “the obvious design, manufacturing and warnings defects present in the
    subject harness[.]”   Brief in Opposition to Motion for Summary Judgment,
    2/15/17, at page 5 of Exhibit F.
    The trial court entertained oral argument on the motion, at the
    conclusion of which it granted summary judgment to FallTech. Order, 4/5/17.
    The trial court opined that “[t]here is absolutely nothing that would make a
    manufacturer think that” someone would use the product as Mr. Zimmerman
    did, and “it would be a waste of time to take this to a jury” because the jury
    would have to find in favor of FallTech if they followed the court’s instructions
    as to the law. N.T., 4/5/17, at 34-35.
    -4-
    J-S85013-17
    Mr. Zimmerman filed a timely notice of appeal, and both he and the trial
    court complied with Pa.R.A.P. 1925. Mr. Zimmerman presents the following
    questions for our consideration.
    1.    Did the trial court err in finding that [Mr. Zimmerman’s] use
    of the at[-]issue harness was unforeseeable misuse?
    2.    Did the trial court err in finding that [Mr. Zimmerman]
    should have been able to discern from the incomplete user
    instructions that he was not using the at[-]issue harness
    properly?
    3.    Did the trial court err in finding as a matter of law that no
    juror could find that [Mr. Zimmerman] acted as a reasonable
    and prudent person under the circumstances?
    4.    Did the trial court err in finding that a jury could not find in
    favor of [Mr. Zimmerman] based on the evidence of record?
    Appellant’s brief at 5.
    We begin our review with the applicable legal principles.
    [S]ummary judgment is appropriate only in those cases where the
    record clearly demonstrates that there is no genuine issue of
    material fact and that the moving party is entitled to judgment as
    a matter of law. When considering a motion for summary
    judgment, the trial court must take all facts of record and
    reasonable inferences therefrom in a light most favorable to the
    non-moving party. In so doing, the trial court must resolve all
    doubts as to the existence of a genuine issue of material fact
    against the moving party, and, thus, may only grant summary
    judgment where the right to such judgment is clear and free from
    all doubt.
    An order granting summary judgment will be reversed if the trial
    court committed an error of law or abused its discretion. The
    decision relating to whether there are no genuine issues as to any
    material fact presents a question of law, and therefore, on that
    question our standard of review is de novo. This means we need
    not defer to the determinations made by the lower tribunals. It is
    settled that, [i]f there is evidence that would allow a fact-finder to
    -5-
    J-S85013-17
    render a verdict in favor of the non-moving party, then summary
    judgment should be denied.
    Malanchuk v. Sivchuk, 
    148 A.3d 860
    , 865-66 (Pa.Super. 2016) (en banc)
    (internal citations and quotation marks omitted).
    Mr. Zimmerman’s primary cause of action is a claim of strict products
    liability under § 402A of the Restatement (Second) of Torts. “To prevail in an
    action under § 402A, the plaintiff must prove that the product was defective,
    the defect existed when it left the defendant’s hands, and the defect caused
    the harm.”    Barton v. Lowe’s Home Centers, Inc., 
    124 A.3d 349
    , 354
    (Pa.Super. 2015).
    The plaintiff may prove defective condition by showing either that
    (1) the danger is unknowable and unacceptable to the average or
    ordinary consumer, or that (2) a reasonable person would
    conclude that the probability and seriousness of harm caused by
    the product outweigh the burden or costs of taking precautions.
    The burden of production and persuasion is by a preponderance
    of the evidence.
    . . . Whether a product is in a defective condition is a
    question of fact ordinarily submitted for determination to the
    finder of fact; the question is removed from the jury’s
    consideration only where it is clear that reasonable minds could
    not differ on the issue.
    Tincher v. Omega Flex, Inc., 
    104 A.3d 328
    , 335 (Pa. 2014).
    Mr. Zimmerman also claimed that FallTech was negligent. “Negligence
    is the absence of ordinary care that a reasonably prudent person would
    exercise in the same or similar circumstances.” Schemberg v. Smicherko,
    
    85 A.3d 1071
    , 1075 (Pa.Super. 2014).       To prove a negligence claim, “the
    plaintiff must prove the following four elements: (1) a legally recognized duty
    -6-
    J-S85013-17
    that the defendant conform to a standard of care; (2) the defendant breached
    that duty; (3) causation between the conduct and the resulting injury; and
    (4) actual damage to the plaintiff.”   Reason v. Kathryn’s Korner Thrift
    Shop, 
    169 A.3d 96
    , 101 (Pa.Super. 2017) (citation omitted).
    Under Pennsylvania law, Mr. Zimmerman’s use of the harness in an
    unforeseeable or highly-reckless manner could serve to defeat his § 402A
    claim. Our Supreme Court has recognized that product misuse and highly-
    reckless conduct are affirmative defenses to a strict liability claim. Reott v.
    Asia Trend, Inc., 
    55 A.3d 1088
    , 1097 (Pa. 2012). The differences between
    them are as follows.
    To establish misuse of the product, the defendant must show that
    the use was “unforeseeable or outrageous.” Highly reckless
    conduct is akin to evidence of misuse and requires the defendant
    to prove that [the plaintiff would have been injured despite the
    curing of the alleged product defect, or that] the use was so
    extraordinary and unforeseeable as to constitute a superseding
    cause.
    Id.at 1096 (citation omitted).
    Similarly, Mr. Zimmerman cannot recover on his negligence claim under
    the comparative negligence statute if his fault in causing his injuries was
    greater than that of FallTech.   See Rekun v. Pelaez, 
    976 A.2d 578
    , 581
    (Pa.Super. 2009); 42 Pa.C.S. § 7102(a).
    As noted above, FallTech contended that it was entitled to judgment as
    a matter of law because Mr. Zimmerman misused the harness. Specifically,
    FallTech argued that Mr. Zimmerman’s misuse was so reckless that it defeated
    -7-
    J-S85013-17
    the causation elements of his claims. See Appellee’s brief at 29-30. The trial
    court agreed with FallTech, concluding that the questions could “be resolved
    simply by common sense without regard to case law or statute.” Trial Court
    Opinion, 8/15/17, at unnumbered 1.      The trial court held as a matter of law
    that it was impossible for FallTech to have anticipated that Mr. Zimmerman
    would have failed to use the product in full compliance with its instructions
    and warnings, reasoning as follows.
    The instruction sheet provided all the information needed in the
    use of the harness. [Mr. Zimmerman] ignored its instructions (in
    words and diagrams): to attach the harness to a secure anchor
    point above him, “directly above the user”; to attach the harness
    to a D-ring on the back of the harness (“back-up fall arrest”); to
    ensure that the anchor point be capable of supporting a load of
    5,000 pounds; to be aware that a properly selected anchorage
    point was “critical to the success of a personal fall arrest system”;
    to limit free fall to nine and a half feet; to “not work above the
    anchorage point”; to use “Side D-Rings (if present) for work
    positioning only, and not be used for fall arrest”; and that
    “instructions, labels and warnings supplied with this full body
    harness . . . must be read and followed before using” and that
    “failure to do so could result in serious injury or death.”
    [FallTech] could not have foreseen that [Mr. Zimmerman]
    would act totally contrary to all the above instructions. Nor could
    [FallTech] have imagined that [Mr. Zimmerman] would use the
    harness in cutting limbs from a tree; swing the harness support
    strap over the stump of a cut-off limb 35 feet above the ground
    and make himself the anchor; wear the harness backwards,
    placing the back D-Ring on his chest rather than his back; step off
    the branch that was supporting his weight and swing around the
    cut-off branch with only feet against the tree as support in
    imitation of woodsmen he had watched on a television reality
    show (that had warned untrained persons not to attempt to
    duplicate their actions), all the above while acting in defiance of
    warnings on printed and sewn-in instructions for use and without
    any training or assistance from anyone who was experienced in
    using the harness.

    Id. at unnumbered
    2.
    We first consider the propriety of the trial court’s analysis as to Mr.
    Zimmerman’s § 402A claim. “It is well-settled that a plaintiff’s misuse of a
    product cannot be grounds for granting summary judgment in favor of the
    manufacturer under a design defect theory unless it is established that the
    misuse solely caused the accident while the design defect did not contribute
    to it.” Smith v. Yamaha Motor Corp., 
    5 A.3d 314
    , 321 (Pa.Super. 2010)
    (emphasis added).
    Mr. Zimmerman contends that the evidence before the trial court was
    sufficient to survive summary judgment, pointing to this Court’s decision in
    Smith v. Yamaha Motor 
    Corp., supra
    . In that case, the plaintiff was injured
    when his leg became stuck in the wheel well of his ATV after the fender
    collapsed, causing the vehicle to roll on top of him. He sued Yamaha, asserting
    claims of strict product liability and negligence. Yamaha moved for summary
    judgment, arguing that Smith misused the ATV by ignoring an instruction
    booklet that “warned that operators should not use drugs or alcohol or allow
    the vehicle to roll backwards on a hill.” 
    Id. at 317.
    The trial court granted
    the motion, concluding that Smith did not use the ATV as intended.
    We reversed, distinguishing cases such as Pennsylvania Dep't of Gen.
    Servs. v. U.S. Mineral Prod. Co., 
    898 A.2d 590
    (Pa. 2006) (holding
    manufacturer of building products could not be strictly liable for PCB
    contamination that followed a fire in the building because the incineration of
    -9-
    J-S85013-17
    the products was not an intended use), and Phillips v. Cricket Lighters, 
    841 A.2d 1000
    (Pa. 2003) (ruling trial court properly entered summary judgment
    in favor of manufacturer of cigarette lighter in strict liability claim for a fire
    started by a toddler who took a lighter from his mother’s purse, as the product
    was intended for use only by adults), by explaining as follows.
    In the present case, the trial court erred in concluding that
    Mr. Smith was not using the ATV as intended. An ATV is an off-
    road vehicle and its intended utilization is to be driven in an off-
    road setting. The ATV at issue herein clearly was being used for
    that purpose at the time of this accident. Mr. Smith was operating
    the ATV on a trail in a wooded area when the accident occurred.
    This case bears no resemblance to either Pennsylvania
    Department of General Services or Phillips.                  Building
    materials are intended to be installed in structures and not to be
    incinerated. Similarly, lighters are manufactured so that adults
    may ignite cigarettes, candles or fires; they are not designed to
    be utilized by children as a toy or plaything. However, ATVs are
    designed to be driven in an off-road setting, and Mr. Smith was
    utilizing the ATV in that capacity when the accident occurred. . . .
    In the present case, the trial court conflated the doctrine of
    unintended use with the concept of misuse. Yamaha’s defense
    was that Mr. Smith was not using the ATV in accordance with the
    instructions that he received with that vehicle. Those instructions
    provided that the ATV should not be used under the influence of
    drugs or alcohol and that the ATV should not be backed down a
    hill. Mr. Smith had taken OxyContin for pain associated with a
    pre-existing back injury in accordance with his prescription for
    that drug. In addition, he had imbibed a small amount of beer.
    Finally, he was backing his ATV down a hill in first gear in order to
    avoid striking other ATV users who were over the hill and out of
    his sightline. These actions relate to the defense of misuse of the
    product in that the ATV was not being used in accordance with the
    manufacturer’s instructions. It is well-settled that a plaintiff’s
    misuse of a product cannot be grounds for granting summary
    judgment in favor of the manufacturer under a design defect
    theory unless it is established that the misuse solely caused the
    accident while the design defect did not contribute to it.
    - 10 -
    J-S85013-17
    
    Id. at 321
    (citation omitted). We went on to consider the record in the light
    most favorable to Smith, noting that he testified that his use of the vehicle
    was not affected by his drug and alcohol use, and his expert opined that Smith
    was not negligent; rather, a design defect in the ATV’s fender was the cause
    of Smith’s injuries. 
    Id. at 321
    -22. Upon this, we concluded that the entry of
    summary judgment on Smith’s strict liability claim was erroneous. We also
    held that the trial court erred in deciding the negligence claim as a matter of
    law, because Smith’s expert sufficiently identified safer alternate designs for
    the fender that would have prevented the accident. 
    Id. at 323.
    Mr. Zimmerman likens the instant case to Smith, in that he was using
    the harness in a foreseeable application consistent with its intended use (to
    stop someone working above ground from falling), and that FallTech failed to
    establish that any misuse of the harness by Mr. Zimmerman was the one and
    only cause of the accident. Appellant’s brief at 17-19.
    Mr. Zimmerman also highlights the following facts of record not
    accounted for by the trial court. The instructions supplied with the harness
    Mr. Zimmerman used were not specific to that model number, but instead
    applied to several different harness models. The diagrams in the instruction
    manual provided with the harness used by Mr. Zimmerman do not depict the
    side D-rings that were on the harness in question. Those side D-rings are
    identical in material and appearance to the back D-ring to which the harness
    is designed to be attached. There were warnings sewn into the material where
    - 11 -
    J-S85013-17
    the side rings were attached to the harness indicating that the side D-rings
    were not to be used for “fall arrest,” but it did not explain that term or specify
    that the load carrying capabilities of the side D-rings were different than the
    identical-looking back ring. Appellant’s brief at 15-24.
    Mr. Zimmerman further points to the report of his engineering expert,
    Dr. Glancey, who observed that the instruction manual “provides no
    instruction or guidance for the use of the subject harness. Specifically, the
    manual fails to instruct a user regarding the purpose of the side D[-]rings or
    the proper use of the side D[-]rings.”        Brief in Opposition to Motion for
    Summary Judgment, 2/15/17, at page 4 of Exhibit F.             Dr. Glancey also
    addressed FallTech’s “assertion that the subject harness was never intended
    to be used by an arborist or in the tree industry,” by observing that “the
    subject instruction manual never articulates the intended uses or, by contrast,
    explains the applications not appropriate for this design.” 
    Id. This failure
    to
    explain the appropriate use, or identify inappropriate uses, “constitutes a
    significant warnings defect” in Dr. Glancey’s opinion.     
    Id. Based upon
    his
    review of the discovery materials, his examination of the harness itself and
    the instructions FallTech identified as accompanying that harness model, as
    well as his inspection of the site and chainsaw Mr. Zimmerman was using when
    he fell, Dr. Glancey offered the following opinions within a reasonable degree
    of engineering certainty:
    - 12 -
    J-S85013-17
    1.    Mr. Zimmerman was using the subject harness for a
    foreseeable application based on the instructions provided
    in the manual for this harness.
    2.    The size and weight rating of the subject harness indicate
    that it was compatible with the weight of Mr. Zimmerman
    and the tools he was using at the time of the incident.
    ....
    6.    The use of the identical steel D-ring for both the dorsal ring
    and the side rings suggests that these components perform
    similar functions and possess the same load carrying
    capabilities. This constitutes a design defect.
    7.    FallTech failed to design the subject harness in a manner to
    resist foreseeable loads exerted on the harness and harness
    subsystems.
    8.    FallTech failed to design their products to insure proper
    attachment of various FallTech systems. Specifically, color
    coding of D-rings and snaphooks to indicate to a user the
    correct assembly of harnesses and lanyards.
    9.    FallTech failed to design their products to insure proper
    connect of D-rings and snaphooks so that only compatible
    components were connected by a user. Specifically, the
    mechanical attributes and features of the D-rings and
    snaphooks were lacking in order to prevent unintended
    connection of these components, namely lanyards to side
    D-rings.
    10.   Had the subject harness and lanyard incorporated color
    coding on the connecting components in order to insure
    proper connect these systems, the serious risk to Mr.
    Zimmerman would have been significantly reduced.
    11.   Had the subject harness and lanyard incorporated
    “mechanical compatibility” into the connecting components
    in order to insure proper connect these systems, the serious
    risk to Mr. Zimmerman would have been significantly
    reduced.
    - 13 -
    J-S85013-17
    12.   The unusual orientation of the laminated straps as well as
    the stitches used to form the side D-ring stitched eyes in the
    subject harness may reflect a manufacturing defect that can
    be confirmed once the engineering design drawings,
    specification, and manufacturing records are produced by
    FallTech for the . . . subject harness.
    13.   The instructions designed and published by FallTech for the
    subject harness failed to warn a user that the harness
    design was not intended for use in the arborist industry.
    This constitutes a warnings defect.
    14.   The instructions design and published by FallTech for the
    subject harness failed to explain in any way the intended
    uses of the side D-rings incorporated into the subject
    harness design. This constitutes a warnings defect.
    ....
    16.   Taking all of the above in to consideration, the obvious
    design, manufacturing and warnings defects present in the
    subject harness that was worn by Mr. Zimmerman were the
    proximate cause of his severe and substantial injuries.
    
    Id. at 4-5.
    Thus, Dr. Glancey identified several design and warnings defects
    in light of safer alternative designs available to FallTech.
    Upon review of the record and application of the legal principles
    discussed above, we conclude that Mr. Zimmerman tendered sufficient
    evidence that, if accepted by the fact finder, would establish that the harness
    was defective, that FallTech was negligent in the product’s design and
    instructions, and that these deficiencies were a proximate cause of Mr.
    Zimmerman’s injuries. Therefore, it was error for the trial court to rule, on
    the record before it, that Mr. Zimmerman’s misuse of the harness “solely
    - 14 -
    J-S85013-17
    caused the accident while the design defect did not contribute to it.” 2 Smith,
    supra at 321.
    We next consider the trial court’s determination that Mr. Zimmerman’s
    negligence claim fails because his misuse of the product was unforeseeable.
    We first note that “the concept of foreseeability means the likelihood of the
    occurrence of a general type of risk rather than the likelihood of the
    occurrence of the precise chain of events leading to the injury.” Charlie v.
    Erie Ins. Exch., 
    100 A.3d 244
    , 256 (Pa.Super. 2014) (quoting Huddleston
    v. Infertility Ctr. of Am., Inc., 
    700 A.2d 453
    , 460 (Pa.Super. 1997))
    (emphasis in original).
    If the actor’s conduct has created or increased the risk that a
    particular harm to the plaintiff will occur, and has been a
    substantial factor in causing that harm, it is immaterial to the
    actor’s liability that the harm is brought about in a manner which
    no one in his position could possibly have been expected to
    foresee or anticipate.
    Ford v. Jeffries, 
    379 A.2d 111
    , 115 (Pa. 1977) (quoting Restatement
    (Second) of Torts § 442B cmt. b).              Thus, in examining the impact that
    foreseeability has on the causation components of Mr. Zimmerman’s
    negligence claim, the question before us is not whether a user would have

    2Indeed, despite seeking judgment as a matter of law based upon causation,
    FallTech did not produce an expert to opine that Mr. Zimmerman’s conduct
    was the sole or primary cause of his injuries.
    - 15 -

    done precisely what Mr. Zimmerman did, but whether FallTech’s conduct
    caused or increased the risk of Mr. Zimmerman’s injuries.
    FallTech contends that Mr. Zimmerman cannot prevail on his negligence
    claim because “reasonable minds cannot differ in coming to the conclusion
    that Mr. Zimmerman did not act as a reasonably prudent person” in, inter
    alia,3    not reading completely the label sewn onto the harness, wearing it
    backwards, and using it as he had seen harnesses used by woodsmen
    ____________________________________________
    3 FallTech contends that one of the ways Mr. Zimmerman misused the harness
    was by using it thirty-five feet above ground, and thus “exceeding the
    maximum free-fall allowed by 25 feet.” Appellee’s brief at 49. The argument
    that the harness was not intended to be used by people who are more than
    ten feet above ground is nonsense. The instruction manual indicates that the
    harness must be anchored such that the user’s weight is not borne by the
    harness after a free-fall of more than six feet. See Motion for Summary
    Judgment, 1/19/17, at Exhibit D, § 5. In other words, the user is not supposed
    to work above the anchor point such that he falls a distance greater than the
    length of the line connecting the harness to the anchor before the fall is
    arrested. 
    Id. The illustration
    provided is as follows.
    
    Id. Mr. Zimmerman
    described attaching one end of the line to one D-ring of
    the harness, wrapping it around the tree, and attaching the other end to
    another D-ring. As such, Mr. Zimmerman intended zero feet of free fall. The
    only reason there was any free fall at all is because the side D-ring ripped
    away from the harness, causing Mr. Zimmerman to fall to the ground.

    although “he was wearing a harness not intended to be used for climbing
    trees.” Appellee’s brief at 48-49.
    The law is clear that “[t]he issue of contributory negligence may be
    removed from the jury where the evidence is so clear and palpable that there
    is no room for fair and reasonable persons to differ in their conclusions . . . .”
    McDole v. Bell Tel. Co. of Pennsylvania, 
    656 A.2d 933
    , 936 (Pa.Super.
    1995). “[W]here there is any evidence which alone could justify an inference
    of a disputed fact [regarding a plaintiff’s negligence], such dispute must go to
    the jury, no matter how strong or persuasive may be the countervailing proof.”
    McCullough v. Monroeville Home Ass'n, Post 820, Inc., 
    411 A.2d 794
    ,
    795–96 (Pa.Super. 1979). “[T]he burden to establish the plaintiff’s conduct
    as a contributing factor in his injury rests with the defendant, who must show
    both the negligence of the conduct alleged and the causal relationship of that
    conduct to the injuries for which damages are sought.”                Angelo v.
    Diamontoni, 
    871 A.2d 1276
    , 1280 (Pa.Super. 2005).
    There is no question that Mr. Zimmerman did not completely read and
    follow the instructions provided by FallTech.       However, Mr. Zimmerman
    produced evidence to suggest FallTech’s negligence was a proximate cause of
    his injuries.   Specifically, as detailed above, Dr. Glancey opined that Mr.
    Zimmerman used the harness for a foreseeable application, that its design
    was defective, and that its warnings were inadequate. Therefore, the record
    shows a material issue of fact as to the relative negligence of Mr. Zimmerman
    - 17 -
    J-S85013-17
    and FallTech.   The question of FallTech’s role in causing Mr. Zimmerman’s
    injuries “must go to the jury, no matter how strong or persuasive may be the
    countervailing proof.” McCullough, supra at 795–96. Therefore, we hold
    that the trial court erred in granting judgment in favor of FallTech on Mr.
    Zimmerman’s negligence claim.
    The trial court did not address Mr. Zimmerman’s breach of warranty
    claim specifically in explaining its ruling. We presume that its decision to grant
    judgment in favor of FallTech on that claim was also based on its finding that
    Mr. Zimmerman unforeseeably misused the harness, as abnormal use of a
    product also may be a defense in a breach of warranty action. Speyer, Inc.
    v. Goodyear Tire & Rubber Co., 
    295 A.2d 143
    , 145 (Pa.Super. 1972).
    Based on our conclusion that there is an issue of fact for the jury to determine
    as to product misuse, we also reverse the trial court’s dismissal of the
    warranty claim.
    For the above reasons, the trial court erred in resolving the question of
    causation at summary judgment.        Therefore, the trial court order granting
    FallTech’s motion for summary judgment is reversed.
    Order reversed. Case remanded for further proceedings consistent with
    this opinion. Jurisdiction relinquished.
