Best Fireproof Gun Safe Review [Complete 2022 Guide]

So, you bought guns to protect your family from thieves and other bad guys that may break into your home. But the reality is, guns are expensive and need another level of security to ensure that they are protected from burglars and fire! 

Some gun safes offer good burglary ratings and ignore fire protection, leaving your valuables vulnerable from flood or fire. Since you’ve spent hard-earned money on them, why not invest in a gun safe with a high burglary rating and a high fire rating? In this post, we’ve got everything you need to know about fireproof gun safes as well as our picks of the best fireproof gun safe for your budget and lifestyle.

Why You Need to Get A Fire-Resistant Gun Safe

Not all gun safes are created equal - some safes are good for concealment or to prevent forceful entry. But, it doesn’t mean that your valuables are safe from fire. 

The ways to build a safe that protects against fire can be very different than protecting against burglary!

Fire accidents are often unexpected and can consume everything you have at home. And, there are over 1 million fires in the US every year! So before you invest in a gun safe, make sure you look for fire-resistance as a feature.

A fireproof gun safe is not only good for storing and protecting your weapons but also other valuable items like pieces of jewelry, pictures, documents, or storage devices that contain sensitive data or media. To properly protect your documents, guns, and other valuable items, a gun safe must maintain an internal temperature below 350 °F.

What You Should Know About Fire Ratings

If you’re concerned about how to protect your valuables from fire, chances are you’ve already done your research online and found many gun safes that offer fire protection. The truth is, not everything you read about fireproof gun safes is true. Some manufacturers simply claim their safes are fireproof based on unregulated fire ratings or without testing. That’s why it’s very important to consider a gun safe that has been thoroughly analyzed and tested against fire vulnerability. 

UL (Underwriters Laboratories) certifications are the most reliable when it comes to assessing fireproof gun safes. You can see some of the certifications listed below for fireproof gun safes:

  • Class 125

This class means that a safe can sustain 80% humidity and an internal temperature of 125 °F (52 °C). It is also sufficient to protect paper documents as well as floppy disks (but UL didn’t specify clearly if it can also protect DVDs, CDs, and Blu-ray disks). The safe’s door also has a water-resistant seal which expands when exposed to heat (water may seep in if not exposed to heat prior to being submerged into the water).

  • Class 150

This class allows a safe to sustain 85% humidity and 150 °F (66 °C) internal temperature, making it sufficient to protect paper articles and storage devices such as compact disks. However, not all safes with this class is waterproof (due to a gasket on its door).

  • Class 350

This class means that a safe can sustain 350 °F (177 °C) and humidity of 85%. The safe is ideal for storing important paper documents (paper’s autoignition temperature is around 450 °F  or 232 °C).

Some gun safes can simply protect your valuables from the direct flames but not from the internal heat. Extreme internal temperatures can destroy some of your temperature-sensitive possessions such as storage devices, ammunition, or documents.

Fireproof gun safes are usually more expensive than an ordinary gun safe because of the hard material it is made of. If you truly want to protect your valuables, then you have to consider how much you are willing to invest. Make sure to consider the construction quality, wall thickness, and the material it is made of so that you can get the best value of your money. Remember, a lower gauge number means a thicker steel (which is better) and a larger gauge number means a thinner steel. A high-quality gun safe must have at least 11 gauge steel in its body and should be 10 to 7 gauge steel.

What to Consider When Choosing A Gun Safe

Shopping for the best fireproof gun safe can be tricky. But if you know what features to look for, you’ll find the best match for your budget and preferences. We’ve summarized a few critical features you should look for in a fireproof gun safe:


Gun safes should not only protect your valuables from fire and other calamities but from thieves as well! Whether we like it or not, burglars will often consider a safe as a big catch because they know it contains valuables like jewelry and guns. So when they see one, they will focus all their efforts to break it open (or carry with them) to get their hands on whatever is inside. 

The most common thing that burglars do is to pry the door of the safe open. When it is protected with locking bolts and thick steel, it’s very difficult for any thieves to pry it open.  If they can tip it over and get at the back, that’s another favorite attack method, which is why it’s so important to attach it to the floor!


Are you a gun collector? Bought guns every time you see a deal online?

Do you need more space to place not just your weapons but also other valuables such as jewelry, cash, and important documents? Then it’s very important to consider the size of the gun safe.  You probably don’t want two safes later, so buy some spare capacity to account for future purchase. 

Fire Protection

The level of fire protection that a gun safe offers differs based on the amount of time and the temperature it can sustain to protect your weapons at a given fire temperature. 

Unfortunately, as we mentioned earlier, most manufacturers come up with their own testing methods and certifications.  The higher the fire protection level is, the better. A lot of high-quality fireproof gun safes can offer at least 30 minutes of protection from temperatures around 1,200 to 1,800 degrees Fahrenheit.

We’ve summarized the different levels of fire protection you can choose, depending on the class and materials.

Five Levels of Fire Protection:

Other Fireproof Gun Safe Facts

How do I set up a fireproof gun safe?

It all depends on the size and weight of the safe, and if you would want to anchor it (to protect it from thieves) or not. Some renters won’t be able anchor their safe permanently, but that drastically decreases the security of your guns.

Most smaller safes come with predrilled holes and bolts so you can attach it to the floor or a wall. Make sure to check the specs from the manufacturer as well as the manual before making a purchase.

How do I maintain a fireproof gun safe?

To ensure your valuables are safe, it’s recommended that you store your guns unloaded and store your ammo separately from your guns. It may sound inconvenient and a little counterintuitive, but practicing this will prevent the ammo and stored gun powder from igniting in case the internal temperature get very high (due to fire). 

It’s very important to clean your safe from dirt and dust. Most manufacturers say at least once a month, but you could probably get away with wiping it down a couple of times a year to make sure the door and locks continue to operate smoothly. 

Also, make sure that the screws and bolts are lubricated once a year. And finally, make sure that the interior of your safe is free from any moisture. Otherwise, your weapons may rust or corrode more easily. It’s recommended that you use a dehumidifier to maintain a good environment for all your valuables.

Will a fireproof gun safe protect my jewelry?

It depends how long the gun safe can protect your jewelry from fire. Often, valuables can be damaged due to extreme heat temperature inside the safe when exposed to fire. Make sure to choose a gun safe that can maintain a safe temperature for your jewelry for a certain amount of time when exposed to extreme temperatures.

Will a fireproof gun safe burn my guns like an oven when there is fire?

It depends on the fireproof rating of your safe. While safes cannot protect your weapons very long, many do offer protection for a certain amount of time. Some safes can protect up to 30 minutes while others can protect up to 2 hours. Make sure that you check the fireproof rating before you buy a gun safe.

Wrapping It Up

Along with protection from burglary, it’s equally important to protect your guns and other valuables from fire and water damage. Choosing the best fireproof gun safes can be overwhelming but like I’ve said, not all gun safes manufacturers are true to their promises. In this post, we’ve summarized everything you need to know about fireproof gun safes as well as our highly recommended safes.
