I must dissent. I cannot conclude, as a matter of law, that defendants had no duty to warn, or that *960defendants’ negligence was not a proximate cause of plaintiffs serious injuries. At the outset it is important to recall that "[t]he failure to warn is essentially a case of negligence and the drastic remedy of summary judgment is rarely granted since the very question of whether a defendant’s conduct amounts to negligence is inherently a question for the trier of fact in all but the most egregious instances (see, Ugarriza v Schmieder, 46 NY2d 471; McFadden v Haritatos, 86 AD2d 761, 762-763)” (Cooley v Carter-Wallace, Inc., 102 AD2d 642, 648).
Defendants maintain that they had no duty to warn plaintiff of the dangers in diving off a deck or ladder into the pool because the dangers are obvious. The obviousness of a danger or the discoverability of it upon inspection, however, does not militate against a duty to warn, but rather is one of many factors for the jury to take into account in assessing comparative fault (see, Micallef v Miehle Co., 39 NY2d 376, 387; PJI 2:135; see also, Schumacher v Richards Shear Co., 59 NY2d 239, 249; cf. Campo v Scofield, 301 NY 468). "[T]he imposition of the duty to give a warning of some kind involves a balancing test which weighs the seriousness of potential harm to the consumer against the costs to the manufacturer. Since the cost of providing warnings is often minimal, the balance usually weighs in favor of an obligation to warn” (Cooley v Carter-Wallace, Inc., supra, p 644).
This record reveals that defendants knew, or should have known, that similar dives into similar pools had resulted in over 100 quadriplegic injuries per year during the past 10 years. Plaintiffs claim is that had defendants adequately warned him of this danger, he would not have taken the dive into the pool. Plaintiff established that it was foreseeable to defendants that people will dive from decks and ladders into the pool. Indeed, the owner’s manual, under the heading "Safety Hints for Pool Owners”, cautions that the pool "contains large quantities of water, however, and is deep enough to present inherent dangers to life and health unless the following safety rules are strictly observed.” One such rule is "Do not dive or permit diving or jumping into the pool from the deck or pool rail. Serious injuries can be caused by failure to strictly follow this rule.” Moreover, plaintiff established that the defendant manufacturer provided small warning decals to the pool owner to be attached in an "appropriate place.” There is then a question of fact precluding summary judgment whether the warnings given were adequate, giving due consideration to the fact that plaintiff was a nonowner of the pool who could not be expected to read the owner’s *961manual before using the pool (Cooley v Carter-Wallace, Inc., 102 AD2d 642, supra; see also, Cover v Cohen, 61 NY2d 261, 275-277; McLaughlin v Mine Safety Appliances Co., 11 NY2d 62, 69; Lancaster Silo & Block Co. v Northern Propane Gas Co., 75 AD2d 55, 64-65).
Assuming defendants breached their duty to warn, there also is an issue of fact whether defendants’ negligence was the proximate cause of plaintiffs injuries. As the Court of Appeals stated in Derdiarian v Felix Contr. Corp. (51 NY2d 308, 315): "[bjecause questions concerning what is foreseeable and what is normal may be the subject of varying inferences, as is the question of negligence itself, these issues generally are for the fact finder to resolve” (see also, Arbegast v Board of Educ., 65 NY2d 161, 171). In opposition to the motion for summary judgment, plaintiff produced extensive evidence bearing on defendants’ knowledge of the dangers in diving into shallow pools. Since varying inferences may be drawn from this evidence, questions of defendants’ knowledge and foreseeability are issues of fact for the jury to resolve (see, Derdiarian v Felix Contr. Corp., supra; Havas v Victory Paper Stock Co., 49 NY2d 381, 388; Palsgraf v Long Is. R. R. Co., 248 NY 339; see also, Prosser and Keeton, Torts § 43, at 297-300; § 45, at 319-321 [5th ed]).
Two recent cases upon which defendants rely heavily (Boltax v Joy Camp, 67 NY2d 617; Smith v Stark, 67 NY2d 693), do not compel a contrary result. Boltax clearly is inapposite since the action was not against a manufacturer and the issue of inadequate warnings was not presented. Both cases involved a perpendicular dive into the shallow end of an in-ground pool following horseplay in which the injured plaintiff took an active part. In the instant case, plaintiff attempted a shallow dive into an above-ground pool with a uniform depth of water. Although swimmers may be aware of the general dangers of diving perpendicular into shallow water, they may also reasonably determine that a flat, shallow dive into four feet of water is not inherently dangerous or unsafe (see, Corbin v Coleco Indus., 748 F2d 411, 417). Thus, plaintiffs dive in the instant case did not, as a matter of law, constitute such an unforeseeable superceding event as to absolve the defendants from all liability (see, Searles v Town of Horicon, 116 AD2d 93).
Accordingly, I would affirm Special Term’s denial of defendants’ motion for summary judgment and allow plaintiff his day in court. (Appeal from order of Supreme Court, Niagara *962County, Cook, J.—summary judgment.) Present—Doerr, J. P., Boomer, Green, Pine and Balio, JJ. »
