There are three categories of product defects: design defects, manufacturing defects, and failure to provide adequate warnings. A design defect means that the design of the product was flawed, and that flaw caused a person’s injuries. A manufacturing defects means that the product’s design was safe, but the party who built the product made a dangerous mistake that caused the product to fail when it was used correctly. Failure to warn means that the product was missing a warning label or other instructions that would have enabled consumers to use the product safely.
