How could a manufacturer or distributor open themselves to liability if their product causes losses or damages to a person or their property?

There are three categories of product defects which may open a manufacturer or distributor to liability: design defects (problems introduced before a product is manufactured), manufacturing defects (errors or impurities introduced when the product is built or produced), or marketing defects (a failure to properly label a product, warn users of dangers, or provide instruction for safe use). Products may also become defective after manufacturing and distribution if they are damaged through improper storage or poorly maintained. In these cases a manufacturer or distributor may share in liability with another negligent person if they could have reasonably prevented this damage through proper warnings.
