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 choking on the block was obvious so as to negate any duty by Playskool to so warn.

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.1 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. Sec. 1501.4, under the Federal Hazardous Substances Act, 15 U.S.C. Secs. 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 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 Sec. 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.2

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 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, 831 F. Supp. 454, 457-59 (W.D.Pa.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;3 (citing Mackowick v. Westinghouse Electric Corp., 525 Pa. 52, 575 A.2d 100, 102 (1990); Dauphin Deposit Bank and Trust Co. v. Toyota Motor Corp., 408 Pa.Super. 256, 596 A.2d 845, 849 (1991)). Thus the district court granted summary judgment in favor of the defendants on all pending claims.

Our review of the district court's summary judgment order is plenary, and we will utilize the same tests and standards which the district court was constrained to apply.4 We will address each cause of action seriatim.

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 Sec. 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, 462 (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 Record5 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.6III.

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 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.7

We must emphasize that under Pennsylvania's interpretation of section 402A strict liability,8 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 Azzarello, 391 A.2d at 1025; Berkebile v. Brantly Helicopter Corp., 462 Pa. 83, 337 A.2d 893, 900 (1975) (plurality opinion) ("Foreseeability is not a test of proximate cause [under strict liability]; it is a test of negligence."); Lewis v. Coffing Hoist Div., Duff-Norton Co., 515 Pa. 334, 528 A.2d 590, 593 (1987) ("... negligence concepts [such as foreseeability] have no place in a case based on strict liability").9 Furthermore, it is the 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 manufacturer intended to use the Playskool building blocks. Without sufficient evidence demonstrating that Playskool intended that the "Ages 1- 1/2--5" user recommendation on the box only pertains to children who are chronologically 1- 1/2 to 5 years old 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 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.

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 Sec. 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 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, 404 Pa.Super. 197, 590 A.2d 348, 351 (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 tantamount to holding that no reasonable jury could conclude otherwise. Based on the evidence of record, we cannot agree.

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.
