Are Gun Safes Fireproof?

Not only gun safes but a lot of general safes are also advertised to be fireproof. Customers thereby always rely on this feature to find their most trustworthy safe to keep precious stuff. Despite being stated as fireproof products, are gun safes fireproof? Let’s find out in this article!

Are Gun Safes Fireproof?

Briefly, a fireproof gun safe CAN protect your stuff from fire. Still, the feature “fireproof” in safe production is not 100% efficient, and the matter is more complicated than it may seem. Why?

There are many gun safes manufacturers on the market, leading to a massive number of gun safes sizes and styles. However, some of them are nothing more than a gun cabinet. These safes don’t offer protection against fire or burglary. When you first find a gun safe for your place, you should consider its metal thickness and locking mechanism as the most noteworthy features.

A gun cabinet is normally constructed from metal, which relatively resembles the 16 to 18 gauge steel. On the other hand, the gun safe’s body consists of around 10 to 12 gauge steel.

Different components serve different purposes to make a complete safe. Among them, the safe door is the most crucial part. When picking a gun safe, you should start with a gun safe having more than ¼’’ solid plate steel door.

If budget is not your concern, then choose the products having at least ½’’ steel door. What’s more, you also have to take the Underwriter Laboratory certificates into consideration, like the Tool Resistant UL.TL-15, or the Residential Security Container RSC.

These qualifications above are for the gun safe’s competence to deal with the relative threats. The effects from these threats on gun safe remain the same in almost every condition. Yet, it is a different story when a fire happens.

In the case of a home fire that results in the collapse of walls, there is a very rare chance that the things you keep in a fireproof gun safe can survive after this accident.

However, this is not the consequence of every fire. Some medium-quality fireproof gun safes still manage to protect their contents in small fires. Sometimes, thick steel non-fireproof gun safes can defeat the damage from fires. It’s all about the seriousness of the fire that matters.

We need to have an honest look that gun owners seem to overstress the fireproof feature to avoid fire from ruining their guns and ammo. Since there haven’t been any more promising fireproof products than a fireproof gun safe, they are still the most optimal choices for us.

Among the fireproof gun safes, we suggest you spend money on the ones which are rated with U.L (Underwriter Laboratories). Those who pass the 1-hour to 90-minute fire test can be adequate to preserve your guns, ammo, or precious stuff through almost all fire cases.

To improve the safety of your properties against fire, you can contain your stuff in a fireproof lockbox. Then, put the box in the safe. Now, you have a double fireproof gun safe.

What Are Must-Have Qualities Of A Fireproof Gun Safe

Why do we suggest you find the U.L-rated gun safes? Due to the various fire types, no one can find out which safe is suitable to handle fire in separate situations.

A group of specialists carries out thorough fire tests to examine a gun safe’s fireproof features in every possible fire situation. The one that still remains intact in as many fire tests as possible will be awarded the certificates.

After numerous tests, the fireproof gun safes that can endure at least one hour of being burned are the ones that are qualified to contain guns, ammo, and valuable things. Fireproof gun safes get destroyed after a less than 60-min fire can also withstand fire, but only the business or home fire.

Will your firearms be secure in a fire-rated safe?

Let me begin by providing some background information. Underwriters Laboratories (U.L.) is a non-profit organization in the United States that certifies safes for both security and fire protection. I discuss how the gun safe industry transformed in the 1980s in my post on safe security. They abandoned traditional safe designs in favor of the new U.L. classification.

U.L. has a wide range of fireproof ratings for safes, similar to security ratings. These ratings indicate how long a safe will remain below a specified temperature for a particular period of time. Security and fire ratings are not the same things. Both of these ratings would be found in a secure fireproof safe.

Class 350 fire ratings are commonly utilized in the realm of gun safes. In the event of a fire, the internal temperature will not exceed 350 degrees for a specific period of time, according to the Class 350 classification. Above 350 degrees, wood and paper begin to decay and burn, thus class 350-1 is 1 hour, class 350-2 is 2 hours, and so on.

Fire-resistant gun safes are made to keep your firearms safe from the heat and flames of a fire. Fire-resistant safes are often manufactured with thicker steel and have a better level of fire protection. It’s crucial to remember, however, that no safe is completely fireproof. While a fire-rated safe will offer more protection than a non-fire-rated safe, it cannot ensure that your guns will remain safe in the case of a fire.

The good news is that your gun safe is safe

Don’t give up on your dreams just yet! A “certification” may not be trustworthy, but you can rely on the numbers. To ensure that your belongings are adequately protected in the event of a fire, make sure that your gun safe has many layers of fire-board, as well as a thicker steel gauge.

Your Safes Fire Testing Is Important.

Additionally, when studying fire-resistant safes, look into the testing methods used by the manufacturer. Companies that take fire testing seriously will put each of their safe models through a series of tests in a furnace to ensure that they provide the protection they promise.

It is recommended that a safe be preheated to 1200 degrees Fahrenheit (the average temperature of a home fire) in 10 minutes, and then maintained at that temperature for the duration of the fire test. When a safe is tested at 1200 degrees Fahrenheit for 30 or 40 minutes, some businesses label the test a success. That’s cheating, according to us. At Liberty Safe, our furnace temperatures are promptly raised and maintained at that level. if we guarantee a 60-minute fire rating, we mean 60 minutes at 1200 degrees.

In The Case Of A Gun Safe, You Get What You Pay For.

The price of your safe will go up if you upgrade your fire protection. It means additional fire-board, thicker steel, and a better seal around the door for improved smoke and fire prevention. It’s worth spending a little more for fire protection, though. Assuming the terrible happens, you won’t regret paying for the additional protection.

What makes gun safes fireproof?

#1 Insulation

Insulation is an indispensable element of any safe. Still, in a fireproof gun safe, gypsum is the insulation you need. The more layers of gypsum in your gun safe, the more proficient its protective feature becomes.

#2 Rigidity And Thickness

Metal is rigid, but being exposed to extreme heat for about an hour is a severe risk for every metal. A residential fire can generate more than 1000 degrees Fahrenheit. At this point, sleek steel will deform in minutes. For this reason, the steel’s rigidity and thickness are the top-notch concern for gun safe buyers.

How Long Will A Safe Last In A Fire

#3 Seals

Although gun safes often have their seals to prevent thefts and burglary, the ordinary seals can be defeated easily towards the fire. To cope with this problem, gun safe manufacturers come up with the intumescent seal.

This is a seal type that can expand its own size along with the rising temperature. Thanks to this special feature, the intumescent seal can save up an enormous amount of time for you to put down the fire and keep the inside stuff intact.

Will a gun survive a house fire?

Safes are designed to resist heat and smoke (and some also guard against water) for a predetermined time. A safe rated for at least one hour of fire protection is what we suggest you buy. For a normal residential fire, safes with a one-hour rating or less will not be sufficient.

How long is a gun safe fireproof?

As mentioned above, a gun safe which is referred to as fireproof should be able to resist fire in at least 1-hour. In contrast, the one that supplies less than 1-hour of fire resistance can’t protect your guns and ammo during a fire.

Are any safes completely fireproof?

No. Nothing is 100% fireproof.

Fireproof products can somehow slow down the damage of a fire case but not totally eliminate the fire’s destruction. When rising to a specific temperature, fire can ruin almost every material.

Bottom Lines

If you are a gun collector, having a gun safe is a must-do work to maintain the optimal condition of your guns and ammo and prevent them from being damaged by a fire case. So, are gun safes fireproof? Yes, but it’s not 100% effective.

As we mentioned above, it mostly depends on the types of gun safe materials and the length of the fire as well. Hopefully, our answers and other detailed information have satisfied you now.
