In a house fire you could lose all of your important documents in a matter of minutes. Fire Safes are meant to keep the inside of your safes at least below 350°. At 375° your paperwork will start to char and eventually ignite. Fire safes can be one of the trickiest safes to purchase. It is important to understand key important features of fire safes before your purchase. Each manufacture tests their safes differently. U.L. (Underwriters Laboratories) is the company that independently tests fire safes. Do not be fooled by terminology. For example, a 2 hour J.I.S. rating is not better than a 1 hour U.L. rating. They could be comparable but, a 1200° F fire for 2 ½ hours is comparable to a 1680° for 1 ½ hours. The average house fire is 1680°. If you want to be sure you’re comparing apples to apples make sure you look at U.L. rated safes. It also means the manufacturer spent extra money to prove they were U.L. certified. You can never be too careful in finding the right safe that will protect your important documents.
