The 7 Best Fireproof Safes
Updated by · How we research
Fire ratings decide this one: seven home safes and chests compared by rated hours, flood seal, lock and room inside. The SentrySafe SFW123DSB is our top pick. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.
No home safe is truly fireproof. A UL fire rating promises only that the inside stays below the point where paper chars, about 350 degrees, for a set time, usually half an hour or one hour. That buys time for firefighters. These picks are for anyone keeping deeds, passports, cash or backup drives at home, and theft is a separate rating.
Editor's Notes
November 1, 2026, by Ezvid Wiki Editors:
The SentrySafe SFW123DSB moves to the top. It pairs a one-hour UL fire rating with a short flood rating and a dial that never needs batteries, and it sells for far less than the big cabinet safes this page used to favor. It was already here, and so was the Phoenix Datacare, now sold as the Phoenix Datacare 2002. It stays because drives and tapes need a cooler inside than paper does.
Seven of the ten old picks are out. The Jolitac Biometric Cabinet, the Honeywell 2118 Dual Lock, the Steelwater Heavy Duty and the Honeywell Safe 1104 Box Chest have disappeared. The SentrySafe EF4738E is really a gun safe with a half-hour rating, and we couldn't confirm the fire rating of the Mesa Safe All Steel with its maker. The First Alert 2030F is down to its last unit. We also dropped the Aitere Document Bag, because fire bags quote huge temperatures without naming any test.
The ranking leans on the UL and Intertek fire and water classifications each maker publishes, the UL 72 classes for paper versus media, and Bob Vila's burn trials of several of these safes. We also checked every brand against federal recall records and found none. We screened a crowd of unbranded safes with oddly styled titles and 35-minute claims, but none named a lab, so none made the cut.
Earlier notes
February 24, 2021, by Will Rhoda:
We removed the Stack-On Personal, Protex Electronic and Docu Ninja Bag due to availability issues, although we were quick to replace the latter option with a similar alternative: the Aitere Document Bag — which can withstand temperatures of 2,500 Fahreneheit and comes with a complimentary, fireproof wallet. Just note that, while this offering can offer an extra layer of fire protection to your valuables, it’s no substitute for some of the heavy duty options in this category.
We also added the SentrySafe EF4738E to our list — a solid option from a well-renowned company that offers more than 4.7 cubic feet of storage space, and comes with attachment hardware so you can bolt it down straight away. It employs five live-locking bolts and four deadbolts to ensure that it’s all but impossible to get its door open without an invitation.
And our last new inclusion this time around was the Jolitac Biometric Cabinet, which became the first biometric safe on this list. It can memorize up to 32 fingerprints, so you can feel free to program in a couple of your own – one on each hand for convenience, plus as a backup in case you happen to wind up with some sort of a cut or blemish on your primary finger – or have it learn your trusted employees’ prints, so you’re not always the one stuck doing the bank deposit.
If you don’t see an option you like here, I’d urge you to keep looking through a few more of our lists. We maintain rankings for many niche safe categories – including drawer safes, wall safes and gun safes – so there’s a good chance that one will include something that speaks to you. Just be careful reading the fine print, if fire-proofing is a priority for you, as many of our picks elsewhere are likely not fire retardant.

When it comes to fireproof safes, it remains hard to beat the top names, including Honeywell, First Alert, and Mesa. We'd like to note that we have not penalized any of these models for needing to be aired out; this is standard with fireproof/waterproof safes because of their construction. But we did decide to remove the Paragon 7800 because of problems with its keypad, which can lead to aggravation in the long run. And we kept the Protex Electronic, even though it's not a self-install option for many. In fact, the company recommends that you have a professional complete the job.
Finally, we added one soft-sided model, the Docu Ninja Bag. It's more portable than many, so if you worry about having to grab your documents and leave quickly, it's a good choice. It would also pair nicely with a run of the mill home safe. But it doesn't offer any real protection against theft, so you shouldn't count on it to stop even casual thieves.
Special Honors
Hollon Oyster Series Hollon's Oyster Series aims at both risks at once: the maker says it passed a two-hour factory fire test at 1850 degrees outside while keeping the inside under 350, survived a 30-foot drop, and uses UL-listed locks. It is a heavy, installed safe for buyers who want burglary resistance as well as fire protection. hollonsafe.com
FireKing File Cabinets For an office or a home with drawers full of records, FireKing makes fire-rated file cabinets that look like ordinary ones. Its Turtle Contour vertical files carry a one-hour UL Class 350 rating in two- and four-drawer, letter and legal sizes. fireking.com
What A Fire Rating Actually Promises
Small chests usually hold for 30 minutes at about 1550 degrees; larger safes are rated for one hour at 1700 degrees.
Every fire safe here is a steel box lined with insulation, and the rating says how long that insulation holds the inside below a set temperature. The UL 72 standard sorts safes into classes by what they protect: Class 350 keeps the inside under 350 degrees Fahrenheit for paper, Class 150 for film and Class 125 for magnetic media such as hard drives (Wikipedia: Safe). SentrySafe states the same 350-degree line for its UL-rated safes (SentrySafe).
The time and outside temperature come next. Small chests usually hold for 30 minutes at about 1550 degrees; larger safes are rated for one hour at 1700 degrees. Bob Vila advises buying a safe that is UL listed or classified, not one merely "tested to UL standards," and notes that Intertek's ETL mark is the usual check for water claims (Bob Vila).
Words like "fireproof" or a quoted 5200 degrees on a document bag mean little without a named lab and a time. Treat such bags as a grab-and-go sleeve inside a real safe, not as protection on their own.
Paper, Cash Or Drives: Match The Safe To What's Inside
Paper money, passports, deeds and photos all sit fine in a Class 350 safe. Plastic and electronics are pickier. Hard drives, backup tapes and older flash media can fail well below 350 degrees, which is why media safes are built to the stricter Class 125 rating (Wikipedia: Safe). SentrySafe says its fire safes are also ETL verified to protect digital media such as USB sticks and discs for the rated time (SentrySafe), but a true Class 125 safe like the Phoenix Datacare 2002 gives far more margin. For most homes, a cheaper answer for data is a backup copy kept somewhere else.
Cash brings up a different risk. A fire rating says nothing about theft, and a small chest can be carried off in seconds. Safes that pair a fire rating with a burglary rating are a separate, heavier class; Hollon, for one, sells a line built for both (Hollon).
For stacks of paperwork, size the box to the folders. Hanging-file chests take letter-size folders upright, and a fire-rated file cabinet suits an office with drawers full of records (FireKing).
Where To Put It And How To Keep It Working
Put the safe where fire and water hit last. Bob Vila suggests a ground floor and bolting the safe down, and warns that a fire rating is not a flood rating (Bob Vila). Most flood ratings are modest: SentrySafe's one-hour models are verified for a day in about 8 inches of water, enough for a burst pipe or hose spray, not a flooded basement. Honeywell claims a deeper seal on its chests, so look there if water is the main threat.
Keypad safes run on batteries; change them on a schedule rather than waiting for the warning. Keep the backup key and a note of the code somewhere other than the safe itself. A dial lock skips batteries altogether.
Fire insulation holds some moisture, so a small desiccant pack inside helps keep papers from going limp. Put irreplaceable photos and papers in sleeves or zip bags. Many safes sold as floor safes simply stand on the floor; a true in-floor safe is set into concrete and is a job for a locksmith.
How we researched this
We compared 23 fire-resistant safes, chests and document bags, read the published fire and water ratings for the 7 picks, compared them against the UL 72 classes, used Bob Vila's burn trials as an outside check where they covered our picks, and checked every brand against U.S. Consumer Product Safety Commission recall records.

Frequently asked questions
Do fireproof safes really work?
Yes, for the time and heat they're rated for. A UL Class 350 safe rated for one hour keeps the inside under 350 degrees for an hour in a standard furnace test, which covers most house fires. They are fire resistant, not fireproof: a long, hot fire can still beat one.
What are fireproof safes made of?
A steel shell with a layer of fire-resistant insulation between the outer and inner walls. The insulation slows heat getting in, and some of it holds moisture, which is why the inside of a fire safe can feel damp.
What is the best fireproof safe for documents and cash?
For most homes, a one-hour UL-rated safe like the SentrySafe SFW123DSB. It holds letter-size papers and cash, and its flood rating covers a burst pipe. For cash, also think about theft: bolt the safe down, because a fire rating is not a burglary rating.
Are fireproof safes waterproof?
Some are, within limits. SentrySafe's one-hour safes are verified for 24 hours in 8 inches of water. Honeywell claims its chests stay dry fully submerged. Many cheap chests, like the SentrySafe 1160, have no water seal at all.
Can I keep hard drives and USB sticks in a fire safe?
Hard drives and tapes need a Class 125 safe, which keeps the inside under 125 degrees. A standard Class 350 safe is built for paper. SentrySafe says its safes are verified for digital media like USB sticks, but a backup kept off-site is the safest plan for data.
Where is the best place to put a fireproof safe?
On the ground floor, bolted down, away from the garage. Keep the backup key and code somewhere else, so you can still open it if you lose one.
