    OPINION OF THE COURT
    __________
    MANSMANN,    Circuit Judge.
    Fifteen month old Matthew Metzgar was tragically
    asphyxiated to death on a purple half-column Playskool building
    block.    In resolving his parents' civil action against the
    manufacturer and the retailer of the toy, brought under
    Pennsylvania's negligence and strict product liability rules of
    law, the district court entered summary judgment for the
    defendants on all four counts of the complaint.
    We address the district court's application of the
    traditional risk-utility analysis which the district court
    utilized in resolving the negligence product liability cause of
    action.     We disagree with the district court on its determination
    that the statistical risk of injury from the Playskool block to
    children like Matthew is so small as to preclude a finding of
    unreasonably defective design.     We also address the district
    court's construction of the "intended user" element of the strict
    liability cause of action.     We reject the district court's
    determination that the age guideline on the product packaging
    precludes the manufacturer's liability for safety when used by
    children, like Matthew, who may be shown to be developmentally
    within the age category, although chronologically slightly
    younger.    We also reject the district court's dismissal of the
    failure to warn claims, brought both in strict liability and
    negligence.    We cannot agree that the danger of a small child
    2
    choking on the block was obvious so as to negate any duty by
    Playskool to so warn.
    I.
    On the morning of February 12, 1990, Matthew's father,
    Ronald, was babysitting Matthew and had placed Matthew, awake and
    healthy, in his playpen.   Ronald left the room for just five
    minutes and upon his return, he found Matthew lifeless.   His
    efforts to revive his son, after he called "911" and removed the
    Playskool block lodged in Matthew's throat, were to no avail.
    The block which caused Matthew's untimely death is a
    cylindrical column, 7/8" wide by 1-3/4" long, the smallest block
    among the 49 brightly colored and variously shaped wood blocks
    marketed by Playskool, Inc.0   Playskool did not place any warning
    of a choking hazard on the box containing the blocks, but clearly
    and boldly imprinted on the front, back and top of the box are
    the words, "Ages 1-1/2 - 5."   The size and shape of the block
    satisfied existing federal standards and regulations for risk
    mitigation and cautionary labeling promulgated and enforced by
    the Consumer Products Safety Commission, 
    16 C.F.R. § 1501.4
    ,
    under the Federal Hazardous Substances Act, 
    15 U.S.C. §§ 1261-77
    .
    The Playskool block also met the small toy and toy part standard
    established by the American Society for Testing Materials.
    On February 6, 1992, Mr. Metzgar and Maureen Ingram,
    Matthew's mother, filed a complaint against Playskool, Inc. and

    The blocks are manufactured and packaged for Hasbro,
    Inc. by Strauser Manufacturing, Inc. according to Hasbro
    specifications and are sold under the Playskool name.

    K-Mart Corp., the retailer, setting forth essentially four counts
    under Pennsylvania law:     negligent design, manufacture and sale
    of a toy block of a size and shape which made the block
    susceptible of being swallowed and causing a child to choke;
    strict liability under § 402A of the Restatement (Second) of
    Torts for manufacturing and selling a toy block in a defective
    condition, unreasonably dangerous to intended users, which the
    plaintiffs alleged includes a child of fifteen months; negligent
    failure to warn of the hazard to children of the toy block; and
    strict liability for failing to warn of the product hazard
    potential.    Matthew's parents alleged that the manufacturer's age
    span recommendation on the box was inadequate to warn of the
    block's inherent danger.0
    In ruling upon the defendants' motion for summary
    judgment, the district court found with regard to the plaintiffs'
    negligent design and manufacture cause of action, that although
    the danger of choking was foreseeable, "[t]he historical risk of
    choking from the Playskool blocks is so small that, even ignoring
    the issue of parental supervision, the risk from the design as a
    matter of law is not unreasonable."     District Court Opinion   of
    Sept. 9, 1993 at A. 21.     The court dismissed this cause of
    action.   Further, in light of the explicit age designation on the
    box, the district court found that Playskool did not subjectively
    intend a fifteen month old child to use this particular Playskool

    unspecified express and implied warranties was withdrawn by
    letter dated April 13, 1993.

    product.    Thus the court also dismissed the plaintiffs' defective
    design strict liability cause of action, holding that "[i]f the
    concept of intended use . . . is to retain any meaning
    whatsoever, it necessarily means that use intended from the point
    of view of the manufacturer putting a product into the
    marketplace."    District Court Opinion of Sept. 9, 1993 at A. 13
    (citing Griggs v. Bic Corp., 
    981 F.2d 1429
     (3d Cir. 1992)
    (product not defective unless it possesses a feature which
    renders it unsafe for its intended use); Brantner v. Black &
    Decker, C.A. No. 93-1J, slip op. at 7-12 (W.D. Pa. Aug. 23,
    1993)).    Further, reasoning that no warning is necessary where a
    risk of danger is obvious, the district court concluded as a
    matter of law that the likelihood of a young child choking on a
    small block is too obvious for the court to sustain the
    plaintiffs' failure to warn strict liability and negligence
    causes of action;0 (citing Mackowick v. Westinghouse Electric
    Corp.,

    , 
    596 A.2d 845

    judgment in favor of the defendants on all pending claims.

    will address each cause of action seriatim.
    II.
    We are troubled by the district court's summary
    judgment disposition of the plaintiffs' negligent design and
    strict liability design defect causes of action.   With regard to
    the negligence claim, the district court properly engaged in a
    risk-utility analysis.   Griggs, 981 F.2d at 1435-36 (negligence
    law requires balancing of risk in light of social value of
    interest at stake, and potential harm, against value of
    conflicting interest) (citing W. Page Keeton et al., Prosser and
    Keeton on Torts § 31, at 173 (5th ed. 1984); Benson v.
    Pennsylvania Cent. Transp. Co., 
    463 Pa. 37
    , 
    342 A.2d 393
    , 397
    (1975); Clewell v. Pummer, 
    384 Pa. 515
    , 
    121 A.2d 459

    (1956)); see also Kleinknecht v. Gettysburg College, 
    989 F.2d 1360
    , 1369-70 (3d Cir. 1993) (the classic risk-utility analysis
    is used to determine whether a risk is unreasonable in a
    negligence cause of action).   In performing this analysis, the
    district court relied heavily on the statistical fact that the
    general population of small children suffer a mortality rate from
    choking on small toys or toy parts of approximately only one per
    720,000 children.   We note also that according to Playskool's
    representative, Charles Fischer, over the past twenty years, the

    Playskool block in question, of which easily hundreds of
    thousands have been sold, has not generated any complaints of
    choking deaths or injuries.      A. 286; 299.   Nevertheless, the
    plaintiffs' expert, E. Patrick McGuire, reported for the record
    that in one year studied, 1988, there were eleven deaths due to
    aspiration of small toys or toy parts by children.       A. 79.   The
    record does not indicate the current infant mortality rate due to
    small toy related asphyxiation, but the plaintiffs submitted a
    CPSC estimate reported in the House Congressional Record0 that in
    each year from 1980-88, an average of 3,200 small children were
    treated in hospital emergency rooms for toy related ingestion and
    aspiration injuries.   A. 476.    The CPSC also reported that
    between 1980 and 1991, 186 children choked on small toys, toy
    parts, and other children's products.
    We share the district court's concern that without "at
    least a realistic threshold of risk," District Court Opinion of
    Sept. 9, 1993 at A. 21, n.10, courts should avoid intrusion into
    product design by too readily weighing risk-utility factors
    against the defendant, even in those cases where a grievous
    injury has been suffered.   Nonetheless, we believe that an annual
    mortality rate of eleven is a "realistic threshold of risk" in
    this case.   The fact that the Playskool purple half-column block
    has not been a contributor to the infant mortality rate until now
    may be simply happenstance from which we cannot conclude that the

    block will be safe for future reasonably foreseeable users.     We
    note that although the purple half-column was in technical
    compliance with CPSC and ASTM standards, the block only minimally
    met the required standards by protruding in length slightly
    beyond the ASTM test cylinder.   The block's width, however, was
    slightly narrower than the test cylinder.   It appears that a
    slight modification to the block design could virtually eliminate
    the choking potential without detracting from the block's
    utility.   We do not believe that the evidence demonstrates,
    therefore, that the risk of a reasonably foreseeable user choking
    on the block is so relatively small -- measured against the
    block's decreased utility by modifying its present design -- as
    to permit summary judgment for the defendants on the basis of a
    risk-utility analysis.   Therefore, we will vacate the summary
    judgment order as it pertains to the claim of negligent design.0
    0
    Judge Scirica would affirm the grant of summary
    judgment to Playskool on the negligent design claim on the basis
    of the district court's risk-utility analysis, which noted that
    the purple block exceeded the CPSC minimum size for toys for
    children under three. Where there is utility to the toy's size,
    the toy is safe for children of certain ages or under
    supervision, it is accompanied by adequate warnings, and the
    statistical probability of the risk is extremely low, the risk-
    utility analysis may preclude a negligent design claim.
    Otherwise, it would appear that every marble would be subject to
    a negligent design claim. The only evidence on the risk posed by
    the block consisted of statistics on children's choking injuries
    and deaths from congressional testimony, but there was no
    evidence the choking incidents in the statistics involved objects
    of comparable size to the purple block. Indeed, Congresswoman
    Collins cited the statistics as evidence that children were
    choking on toys that were, unlike the purple block, smaller than
    the CPSC minimum. 138 Cong. Rec. H8264.
    While Judge Becker believes that Judge Scirica's
    argument has considerable force, he adheres to the opinion of the
    8
    III.
    We turn now to the district court's summary judgment
    disposition of the plaintiffs' strict liability design defect
    claim.    We quite agree with the district court's reiteration that
    "a product is not defective unless it possesses ``any feature that
    renders it unsafe for the intended use,'" and that the concept of
    intended use "``encompasses the participation of an intended
    user.'"    District Court Opinion of September 9, 1993 at A.10
    (citing Griggs v. BIC Corp., 
    981 F.2d 1429
    , 1433 (3d Cir. 1992)
    and Azzarello v. Black Bros. Co., 
    480 Pa. 547
    , 
    391 A.2d 1020
    ,
    1027 (1978)).    We are much less certain, however, that Matthew,
    at age fifteen months, was not an intended user of this
    particular product.    The eighteen month to five year
    recommendation boldly marked on the Playskool box is not, to our
    minds, an unequivocal indication that these blocks are unsuitable
    for use by a child who is just three months shy of eighteen
    months, particularly given the potential disparities among young
    children in the relation of their chronological age to their
    court because he believes that the statistical evidence
    concerning the magnitude of the risk of asphyxiation and related
    injures to children under the age of six may support a finding
    that all intended and likely users of the blocks are exposed to
    an unreasonable risk of asphyxiation. That is, to the extent
    that legally adequate warnings would leave no real market for the
    product (because, for example, the warning would have to include
    all children under the age of six and children over the age of
    six would have no real interest in the blocks), the plaintiffs
    could prevail on the negligent product design claim. Judge
    Becker notes in this regard that, were it unreasonable, given the
    nature of the particular product in light of its intended use, to
    expect an adult to engage in constant supervision of a child
    playing with it, a warning that the product should be used only
    with adult supervision would be legally inadequate.

    physical and mental "developmental age."   Moreover, the
    plaintiffs produced several experts who concluded that
    Playskool's age guideline pertained to the intended user's
    developmental stage.0
    We must emphasize that under Pennsylvania's
    interpretation of section 402A strict liability,0 an "intended
    user" of a product is not so broad a class as to encompass every
    user reasonably foreseeable to the manufacturer.    Foreseeability
    pertains to a duty analysis under negligence tort law, but
    strictly speaking does not form a part of the appropriate
    analysis under Pennsylvania strict products liability law.
    Griggs, 981 F.2d at 1435 (". . . the ``duty' analysis in strict
    liability eschews foreseeability as an element").   See also

    The plaintiffs submitted three expert reports to the

    Theodora Briggs Sweeney, A.70-73, and E. Patrick McGuire. A.77-
    81. All three experts concurred that the age guideline served
    primarily as a developmental gauge, and did not convey safety
    hazard information based solely or primarily on the child's
    chronological age.

    Prior to Griggs, in our reported decisions we did not
    carefully distinguish the role of foreseeability in negligence
    and in strict liability, and the concept has become blurred in
    the two contexts. See Fleck v. KDI Sylvan Pools, Inc.,

    567 F.2d 1259
    , 1263 (3d Cir. 1977)
    ("``. . . whether a particular use of a product is abnormal
    depends on whether the use was reasonably foreseeable by the
    seller'") (citing Kuisis v. Baldwin-Lima-Hamilton Corp.,

    Kaczmarek v. Mesta Machine Co., 
    463 F.2d 675
     at 679 (3d Cir.
    1972)). In Griggs, in attempting to retain the important
    distinction between negligence and strict liability, we rejected
    the term "foreseeability" in the context of a strict liability
    analysis.
    We note some difference in the panel's view here: Judge
    Mansmann would emphasize Griggs' sensitivity to keeping the
    terminology of negligence and strict liability distinct, and also
    reaffirm an objective standard to determine the manufacturer's
    intent in a strict liability analysis. See also, Pacheco v. The
    Coats Co., Inc., No. 93-1791, Slip op. at 8 (3d Cir. June 6,
    1994) (acknowledging that "foreseeability" is a term of
    negligence, although an objective standard is appropriate to a
    strict liability analysis of manufacturer's intent). Judge
    Becker and Judge Scirica believe that, at least insofar as Griggs
    rejected a forseeability analysis in context of the intended use
    (as opposed to the intended user) analysis, Griggs departed from
    prior Third Circuit caselaw just cited on the role played by
    foreseeability in strict liability cases, and to that extent
    carries no precedential weight. See O. Hommel Co. v. Ferro, 659
    11
    court which decides the threshold determination of the product's
    intended use based upon the parties' averments, and as part of
    that determination, whether the injured party was an "intended
    user."   Griggs, 981 F.2d at 1432-33.   Thus, the district court
    was obliged to focus on the intent of the manufacturer of the
    Playskool blocks in determining whether Matthew was an "intended
    user" for purposes of resolving the summary judgment motion.    The
    court properly reasoned that a "foreseeable user" such as Matthew
    is not by strict definition coincident with an "intended user."
    Logic and prudence lend weight to the court's unwillingness to
    conflate the "intended user" with the "foreseeable user" in
    strict liability, especially where children are concerned,
    because so many varied and necessary products are hazards in the
    unintended but foreseeable hands of children, but cannot be
    "childproofed" without being rendered significantly less useful
    or even useless.   This is not only true of inherently dangerous
    products, but is, to some extent, true even of toy products.
    Children are inherently vulnerable and in many circumstances, the
    product design cannot replace the adult supervision of a child.
    Our concern here pertains to the fact that unlike the
    circumstances in Griggs involving the use of a BIC lighter by a
    three year old child -- clearly an unintended user -- here the
    record shows a lack of clear indication of who exactly the

    rather than the broader category of children who are
    developmentally 1-1/2 to 5 years old, we decline to accept the
    district court's interpretation of the age guideline indicated on
    the box as a strict chronological age category of intended users,
    which would exclude Matthew.    It is possible that the indications
    on the package refer more broadly to the physical and mental
    aptitude of small children and do not contain any strict
    chronological age implication.   A developmental age category
    might be shown to include Matthew.
    We believe that the "intended user" must be determined
    in the context of the knowledge and assumptions of the ordinary
    consumer in the relevant community, at least, as here, in the
    absence of explicit warnings.    Thus, although foreseeability is
    not a term that should be associated with strict liability, the
    concept, to the extent it implies an objective test, is not
    entirely foreign to a strict liability analysis, although it is
    applied in a more narrow sense than in negligence law.   The
    court's inquiry into the intent of the manufacturer asks what the
    consumer could reasonably have understood the manufacturer's
    intent to be.   Unless the use giving rise to a strict liability
    cause of action is a reasonably obvious misuse, or the user a
    reasonably obvious unintended user, as was the case in Griggs, or
    unless the particular use or user is clearly warned against, the
    13
    manufacturer is not obviously exonerated.   We do not believe that
    here Matthew's parents were clearly alerted to the fact that the
    product presented a special danger to Matthew; nor do we believe
    that it was objectively unreasonable for them to have assumed
    that Matthew was an intended user.   The plaintiffs' experts
    testified that the ordinary consumer in the present case would
    interpret the age guideline to be a developmental age
    recommendation.   Moreover, Charles Fischer, the defendants'
    witness, testified that the "Ages 1-1/2 - 5" guideline
    represented the stage in which "the child has the coordination
    and will derive play value from [the blocks] . . . ," suggesting
    that those years were chosen for their correspondence to a
    child's physical and mental developmental age.   A. 301.
    Furthermore, the evidence of record does not establish that the
    blocks posed a substantially greater risk of choking a fifteen
    month old than an eighteen month old; thus it may be that, even
    assuming that Matthew was an unintended user from the subjective
    perspective of the manufacturer, because it was not shown that
    the block posed a substantially greater risk to the unintended
    user, the manufacturer's subjective intent would not in justice
    be dispositive.
    Because we are not convinced that there was sufficient
    indication to a reasonable consumer that Matthew was not an
    intended user, we will vacate and remand the summary judgment
    order as it pertains to the claim of defective design.
    IV.
    14
    We turn finally to the remaining claims brought in both
    strict liability and negligence on the theory that the defendants
    failed to warn of the hazard potential of their product.     The
    district court reasoned that the risk of a small child choking on
    an object such as one of Playskool's smaller blocks is so
    objectively obvious as to preclude the requirement for a
    cautionary warning as a constituent of the product design, or the
    creation of a duty to provide an express warning of that fact.
    See Dauphin, 
    408 Pa. Super. 256
    , 
    596 A.2d 845
    , 850 (1991)
    (Pennsylvania law imposes no duty to warn of obvious risks);
    Mucowski v. Clark, 
    404 Pa. Super. 197
    , 
    590 A.2d 348
     (1991)
    (standard of obviousness of danger for claim in strict liability
    is virtually identical for purposes of claim in negligence under
    Pennsylvania's application of Restatement (Second) Torts § 388).
    We will vacate the district court's ruling and remand on the
    ground that the question of obviousness in this case was not a
    proper subject of summary judgment.
    We note that although the standard of obviousness is
    the same in strict liability and in negligence, the role of the
    court differs according to the legal theory governing the cause
    of action.    In strict liability, an inadequate warning is a
    species of product defect, and hence is properly decided
    initially by the court as a matter of law.     Mackowick, 
    525 Pa. 52
    , 
    575 A.2d 100
    , 102 (1990) ("The determinations of whether a
    warning is adequate and whether a product is 'defective' due to
    inadequate warnings are questions of law to be answered by the
    trial judge.")    For a risk to be deemed obvious for purposes of a
    15
    failure to warn claim, however, there must be general consensus
    within the relevant community.    We cannot see how the purple
    Playskool block can be deemed as a matter of law an obvious
    safety hazard in the eyes of the relevant community, when
    Playskool itself believed the block was safe for its intended
    use.   Furthermore, Matthew's parents and his aunt, who purchased
    the Playskool blocks for Matthew, testified that they did not
    believe that the product posed an obvious threat of asphyxiation
    to Matthew.   A. 200-01, 376, 442.    Moreover, the defendant did
    not proffer any evidence tending to show that the danger of
    asphyxiation was obvious.
    Under a negligence theory, although a failure to warn
    claim may be defeated if the risk was obvious or known, the
    question of obviousness is more properly submitted to a jury than
    disposed on motion for summary judgment.    See Laaperi v. Sears,
    Roebuck & Co., 
    787 F.2d 726
    , 731 (1st Cir. 1986) (whether danger
    of smoke detector's malfunction was obvious is question for
    jury); Mucowski v. Clark, 
    590 A.2d 348
    , 351 (Pa. Super. 1991)
    (whether absence of warning is legal cause of injury is usually
    matter for trier of fact; but court may decide where only
    reasonable conclusion is that plaintiff's foolhardiness, not lack
    of warning, legally caused injury).    The court's role in deciding
    a motion for summary judgment is merely to decide whether there
    is a genuine issue of material fact for trial.    The district
    court's dismissal of Metzgar's negligent claim on the basis of
    its determination that the danger to Matthew was obvious was
    16
    tantamount to holding that no reasonable jury could conclude
    otherwise.    Based on the evidence of record, we cannot agree.
    V.
    We will vacate and remand that portion of the district
    court's summary judgment order of September 9, 1993 which
    disposes of the plaintiffs' failure to warn claims brought in
    negligence and strict liability.       We will also vacate that
    portion of the district court's summary judgment order of
    September 9, 1993 which disposes of the plaintiffs' defective
    design claims brought in negligence and strict liability, and
    remand for trial on the merits of the complaint.
