A sufficient product warning is one that is clear, conspicuous, and understandable to an average user, alerting them to the potential risks and necessary precautions for safe usage. The manufacturer must provide warnings for known dangers or those that should be known through testing and research. However, they are not required to warn against obvious dangers or misuse of the product.
For example: A power tool manufacturer includes a warning label highlighting the risk of serious injury if safety gear isn’t worn. This alerts users to wear protective equipment, thus meeting the legal obligation for adequate warning.
