We take the thickness of the steel (body and door) and calculate the total steel's BTU value (how much heat the steel can take).We take the total amount of fireboard insulation installed in the safe (ceiling, walls, doorjambs and door) and calculate the fireboard's total BTU value (how much heat those layers can take).No other safe company does what we do to protect valuables from fire. We show you the total number of layers in each safe, how thick the steel is, use only the best fire seal and install more bolts to keep the door tighter. It's unfortunate when some safe companies don't put enough fire board, or worse use spacers to make it appear better than it really is. Our engineers have fire tested more than 300 safes in the past 15 years including many of our competitor's document fire safes. Even the door bolts help by keeping the door from warping and tight against the expanded door seal. But when the temperature reaches 212 degrees the Palusol door seal expands to seven times its size and seals the door so cooler air can't escape and the heat and smoke can't come in.Īt the same time, the molecules inside the fireboard release a cooling effect to keep the temperature down. The steel body of the safe takes the initial brunt of the heat. As the fire grows the temperature will rise reaching 1200 degrees within 10 minutes. When a fire is ignited in a home the temperature is usually around 70 degrees or room temperature.

Here is how a gun fire safe works in a fire. Reliable fire protection is a great benefit when buying a Liberty Safe.
