This safe has been tested by the Underwriters Laboratory. The unit is heated for one-half hour to reach an exterior temperature of 1550 degrees. Because paper will begin to char at approximately 400 degrees, the unit being tested must maintain an interior temperature of less than 350 degrees during heat-up and cool-down testing in order to earn it's rating. At U.L. after the safe has hit the test time the safe is removed from the oven and hoisted 30 feet (equal to 3 flights of a building) and dropped on to concrete rubble, it is allowed to cool and then picked up and placed back into a 2000 degree preheated oven (this is called the explosive test). It is done to see if the door will blow off, then it remains in the oven and the contents of the safe must come out unharmed.
