Are all FireKing files are impact tested?
To be truly fireproof a file must be impact resistant. During a fire floors collapse and ceilings fall. If a fireproof file is not rated for impact it will fail in this situation. All FireKing files carry Underwriters’ Laboratories 1-hour fire and impact rating. To earn the the UL Impact rating a fully loaded file cabinet is heated to 1550 degrees Fahrenheit for one-half hour and then dropped 30 feet onto a bed of rubble. It is then placed back in the oven at 1550 degrees for another 30 minutes. The contents must survive this test to earn the rating.
