How Does Underwriter's Laboratories (UL) Test 350 degrees F Two-Hour Fire Label Safes? The UL Class 350 degree F two-hour safe will maintain an interior temperature less than 350 degree F when exposed to fire for a period of two hours at 1850 degrees F. To earn this stringent UL rating, the safe must successfully pass all requirements for the Fire Endurance Test, Explosion Hazard Test and the Fire/Impact Test listed below. FIRE ENDURANCE TEST First, heat sensors and paper are placed inside the safe. Then the safe is locked and surrounded on all sides by fire in a carefully calibrated testing furnace. The furnace is regulated to reach a temperature of 1850 degrees F for two full hours. Then the safe is allowed to cool without opening the furnace. The interior temperature within the safe is continuously recorded throughout the test and during the cooling period until a definite drop is shown. To pass the UL fire endurance test, the safe's internal temperature must never exceed 350 degrees F. Once cooled, the unit is opened and examined for usability. The unit's locking mechanisms and parts fastenings are examined for security and the interior examined for visible evidence of undue heat transmission. EXPLOSION HAZARD TEST The safe is locked and placed into a testing furnace preheated to 2000 degrees F. This temperature is maintained for 45 minutes. If no explosion results, the unit is allowed to cool without opening the furnace doors. Once cooled, the safe is opened and examined for usability. The safe's locking m
