Yun tung chow tried to unclog a floor drain in the kitchen of the restaurant where he worked. he used a drain cleaner called lewis red devil lye that contained crystalline sodium hydroxide. the product label said to wear eye protection, to put one tablespoon of lye directly into the drain, and to keep one’s face away from the drain, because there could be dangerous backsplash. without eye protection, chow mixed three tablespoons of lye in a can, and poured that mixture down the drain while bending over it. liquid splashed back into his face, causing injury. he brought a product liability suit based on inadequate warnings and design defect. the trial court granted summary judgment to the manufacturer, and chow appealed. an expert for chow stated that the product was defective, because it had a tendency to splash. is that a convincing argument? why or why not?
