“Product liability is the area of law in which manufacturers, distributors, suppliers, retailers, and others who make products available to the public are held responsible for the injuries those products cause.”

A specific example is https://en.wikipedia.org/wiki/Escola_v._Coca-Cola_Bottling_C.... : somebody uses a soda bottle as intended, gets hurt, and wins a case against the manufacturer of the bottle.

If you don’t follow instructions, that still can happen, but it will be harder to argue that a problem originated with the manufacturer.
