Protect your most valuable possessions from the threat of fire with a sturdy safe. Fireproof safes are built to withstand high heat and flames and can also be a deterrent to theft, with combination locks, digital keypads, or standard keys.
It's a wise idea to safely store what could easily be destroyed by the elements—such as important documents, passports, storage media, and jewelry—inside a secured fireproof box. As you browse, you should decide if you need protection from other hazards like water or dropping, what kind of lock you prefer, and how heavy you want the safe to be. Everyone has something to safeguard, so don't risk disaster by leaving your valuables unprotected.

What to Look for in a Fireproof Safe
It’s to be expected that a fireproof safe box will withstand high heat and flames, but not all safes are created equal. Some carry minimal fireproof ratings and can’t take the heat for more than 30 minutes before becoming damaged. Many models are rated for an hour of fire exposure, while the most robust safe carries a two-hour fireproof rating. Additionally, some fireproof safes also are water-tight or have been drop-tested.
Fireproof safes come in a range of different weights, which impacts how portable they are. Some larger safes can weigh 100 pounds or more, which is a great deterrent for thieves but not so great if you want to take your safe on the road. If you’re looking for a fireproof safe that's easy to take with you, you’ll likely want to pick one that weighs less. Many portable versions weigh between 8 and 15 pounds.
Choose a sturdy locking mechanism for your fireproof safe to ensure that the contents stay secure. There are traditional lock and key closures, but the risk is that you may lose the key. Other fireproof safes have a keypad that allows you to enter a passcode to unlock the safe. Finally, some safes have a combination lock that eliminates the concern of lock-picking that comes with having a keyhole.
