What to Look for in a Fireproof Safe

Element-resistance

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 safes carry a two-hour fireproof rating. Additionally, some fireproof safes also are waterproof or have been drop-tested.

Weight

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 eight and 15 pounds.

Lock mechanism

Choose a sturdy locking mechanism for your fireproof safe to ensure that the contents stay secure. There are traditional lock and key closures, but there's a risk 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.

FAQ
  • What are fireproof safes made of?

    The most effective fire resistant safes have a double walled construction, with two sheets of steel and a layer of fire retardant materials in the middle. Fire retardant materials may include cement, gypsum, perlite, vermiculite, or diatomaceous earth, depending on the manufacturer. Cheaper fireproof safes have plastic interior walls covered with fireproof material. Well made fireproof safes also include a strong seal that swells to keep the door firmly shut to keep out flames in the event of a fire. 

  • Will paper money burn in a fireproof safe?

    If the safe doesn’t have a high enough fire safety rating, it just might. If you’re keeping cash in a safe, do yourself a favor and make sure the safe has a high fire safety rating so that you have the best chance of protecting your money (and other important paper-based items) from bursting into flames. While some people feel better having a wad of cash money stashed in a personal safe, your money is probably more protected from fire when stored in a bank or credit union.

  • Are all safes fireproof?

    No safe is entirely fireproof, but safes have varying degrees of resistance against damaging elements such as fire (and water), so be sure to read the fine print to find out just how fireproof (or waterproof) a safe is before purchasing. Individual safes may keep your valuables from burning for as little as 30 minutes or as long as two hours depending on the make and model. If you are storing irreplaceable items, documents, or paper money in your safe, do yourself a favor and invest in one with the highest fire safety rating you can afford to protect your valuables in case of a fire.
