What are the elements of a cause of action in tort for products liability?

25 These are not the elements of a cause of action in strict products liability. Those elements are much more specific, and depend on the theory of liability being asserted. See, e.g., Fane v. Zimmer, Inc., 927 F.2d 124, 128 (2d Cir.1991) (explaining, for example, that in design defect cases the typical plaintiff must show "that (1) the product is 'defective' because it is not reasonably safe as marketed; (2) the product was used for a normal purpose; (3) the defect was a substantial factor in causing the plaintiff's injuries; (4) the plaintiff by the exercise of reasonable care would not have both discovered the defect and apprehended its danger; (5) the plaintiff would not have otherwise avoided the injury by the exercise of ordinary care") (citation and internal quotation marks omitted). Rather, these are the basic requirements for any cause of action in tort for products liability, regardless of the particular theory of recovery.
