UJI 13-1415. Duty of the supplier; warning.

The supplier must use ordinary care to warn of a risk of injury. However, there is no duty to warn of a risk unknown to the supplier, unless, by the use of ordinary care, the supplier should have known of the risk. Under plaintiff’s claim of “products liability”, a product presents an unreasonable risk of injury if put on the market without warning of a risk which could be avoided by the giving of an adequate warning. [The supplier has no duty to warn of risks which the supplier can reasonably expect to be obvious or known to foreseeable users of the product.]
