What is an impact rating on a fireproof cabinet and do you need it?

The UL impact test simulates what happens when a cabinet falls from an upper floor during a building collapse in a fire: the cabinet is heated to fire temperature, dropped 30 feet onto rubble, then reheated for an additional hour. A cabinet with an impact rating (e.g., UL Class 350-1 Hour with Impact) has passed that test and maintained its interior protection. Not all fire-rated cabinets carry this designation — for multi-story buildings, it's an important additional layer of protection worth specifying.
