Documents in a fireproof safe box

The 8 Best Fireproof Safes

Chances are you have valuables in your home that would be difficult or impossible to replace—things like jewelry, passports and financial documents. What are the chances of any of them surviving a fire though? If you’re not keeping them in a fireproof safe of fireproof box, the chances probably aren’t nearly as good as they could be.

When it comes to securing your home, fires are a significant threat. According to a recent report by the National Fire Protection Association, U.S. fire departments respond to an average of 354,400 home fires per year. In addition to the tragic deaths and injuries they cause, home fires are also responsible for $6.9 billion in property damage. While quality smoke detectors and fire alarms can help, fireproof safes and fireproof boxes offer an extra layer of protection for your most important valuables.

So, how do you pick the right fireproof safe? First, it’s important to note that while safes may be labeled fireproof, essentially anything (including all safes) will burn if subjected to high enough temperatures for a long enough period of time. To determine how protective a safe is, you want to look specifically at a safe’s fire resistance rating, which tells you how long it can withstand a fire up to a certain temperature. Beyond that, you’ll want to consider the size of a safe—both its interior and exterior dimensions—as well as other special features it may offer.

To help you narrow things down, SecurityNerd took a closer look at some of the most popular fireproof safes on the market. Here are our eight of our favorites.

1. MSafe PF 32 Fire Safe

You may recognize MSAFE from our top picks for the best home safes. The size on the PF 32 is great – not massive, but at 13-3/8″ wide by 11-5/8″ deep inside it fits documents comfortably. The pull out drawer at the top is also ideal for passports as well. I likely wouldn’t go larger than this in an apartment, but given the space I don’t know that most folks would ever need to.

    • Fire Protection: 1 Hour Fire Protection
    • Exterior Dimensions: 12-3/8″ H x 17-1/2″ W x 16-3/4″ D (+1 inch for the handle and hinges)
    • Interior Dimensions: 8-1/8″ H x 13-3/8″ W x 11-5/8″ D
    • Interior Cubic Inches: 1,270 Cu. In.
    • Interior Cubic Feet: 0.573 Cu. Ft
    • Weight: 84 lbs.

Nerd Pros

  • 1 Hour of Fire Resistance: All the safes in the PF line are tested under the EN 15659 standards.
  • Upgraded Lock: Just like the PSB line, the ring pull handle and electronic keypad are easy to use and feel very high quality.
  • Water Resistant: While not waterproof (since waterproof would mean the entire safe can be submerged, which would rule out the option of bolting down the safe) the PF line is water resistant.

Nerd Cons

  • Burglary rating: The PF line is not a burglary safe, for reference none of the fire safes we have reviewed are.

2. SentrySafe SFW205GQC

SentrySafe is a leader in the home safe industry, and this model gets good marks all around. It provides 2.05 cubic feet of storage inside, so it’s made to hold a significant amount of your valuables, but it also comes in a variety of other sizes to fit various spaces and in models with either a dial combination lock or a digital keypad. A secondary lock requires a key for extra security. It’s certified to keep your valuables safe for up to 1 hour at temperatures reaching 1700 degrees, and an interior light is a nice extra touch to help you see the safe’s contents when it’s opened.

Beyond protection from fires, this safe can withstand a fall of 15 feet in case you need to toss it from a window, and it’s waterproof. Note, however, that if you choose to bolt the safe to the floor, it’s no longer waterproof, as you have to drill holes in it for the bolts.

7 things to consider when choosing a fireproof safe or fireproof box


When evaluating safes, pay attention to both the exterior and interior dimensions. The exterior dimensions will let you know how much space it will take up in a room, while the interior dimensions provide insight into much a safe will hold.


If you plan to move your safe frequently, you want to pay attention to its weight. Some are quite heavy and meant to stay in place, while others are lighter and lend themselves to greater portability.

Fire Rating

The fire rating, typically issued by Underwriters Laboratories (UL) or ETL Testing  Laboratories note how long a safe provides protection from fire and for how long.

Storage Capacity

Beyond the interior dimensions, you can also look at a safe’s storage capacity, which is typically measured in cubic feet.

Locking Mechanism

Safes come with a variety of different locking mechanisms, including traditional dial and key locks to electronic keypads.

Ease of Use

Look at how easy a safe is both to set up and to use. Some are quite heavy, so having them delivered and set up in your home may take extra planning.

Special Features

Some fireproof safes are not only fire-resistant, but they’re also water-resistant (great for protecting valuable from the flood that comes from the fire hoses). Others may feature anti-theft features too such as combination locks and alarms.

What is a UL rating?

While there are various types of ratings when it comes to a safe’s ability to withstand fire, UL ratings are the most common. Issued by Underwriters Laboratories, they certify how long a product can withstand fire within a particular fireproof safe or fireproof box. For example, a UL Class 350-degree 1- hour certification means the interior of the safe won’t climb above 350 degrees (paper burns at 400 degrees)  in a fire that burns for one hour at 1,700 degrees, while a UL Class 125-degree 1-hour certification means the interior won’t reach above 125 degrees (recommended for media such as DVDs and CDs). Most manufacturers simply state the maximum length of time and heat their products are certified to withstand. UL also offers ratings for water resistance and impact resistance.

The bottom line on fireproof safes

While a fireproof safe can’t protect your entire home, it can help protect some of your most important possessions should disaster strike. Consider how many valuables you want to protect, the size of the space you have to house a safe and your own personal circumstances to select the best one for you.
