What is the UL Classification for First Alert Fire Safes?

The UL Classification on our fire safes is Classification 350 which means that during testing the interior of the safe will maintain a temperature of 350 degrees Fahrenheit or less. At this temperature the interior of the safe is cool enough so that paper does not char or burn. The 1-Hour Fire Safes will maintain this temperature in a fire with heat up to 1700°F for one hour, whereas the 2-Hour Fire Safes will maintain that temperature for 2 hours.
