What is an impact rating on a fireproof cabinet?

The UL impact test simulates the fall of a fireproof cabinet from an upper floor during a building collapse in a fire. A cabinet with an impact rating (UL Class 350-1 Hour with Impact) has been tested by being heated to fire temperature, then dropped 30 feet onto rubble, then reheated for an additional hour — simulating a floor collapse scenario. Not all fire-rated cabinets carry an impact rating. For multi-story buildings, the impact rating provides critical additional protection.
