Products liability laws refer to the liability of anyone with a responsibility for a product from the supplier or manufacturer to the seller -- if that product causes damage due to defect. Product liability law has grown to include intangibles (gas), naturals (pets), real estate (house), and writings (navigational charts). Liability claims can be based on negligence, strict liability, or breach of warranty of fitness. The United States Department of Commerce has promulgated a Model Uniform Products Liability Act (MUPLA) for voluntary use by the states. There is no federal products liability law.
Examples of product liabilities involve defective products such as gas tanks, tire defects, air bag injuries, toxic chemicals, some environmental pollution as well as products that do not live up to their respective guarantees or warranties. A product is legally considered defective if it was made poorly or sold with flaws. A product may fulfill its purpose as expected but an injury may occur in normal use. A product may also be safe if used carefully, but it may be considered defective if the manufacturer 's information on how to use it is unclear, incomplete or incorrect. This misrepresentation concerning the product, if resulting in an injury, may entitle the plaintiff to damages.
