How to Build a Fireproof Gun Safe

Not the master bedroom

The location you’re putting the gun safe matters the most when making an existing gun safe fireproof. Usually, people like to keep the safe with precious items inside their bedroom, which can also be the worst decision. When a house gets on fire, the master bedroom is typically the hottest portion of the house because of the furniture and clothes.

Decide the location for the gun safe

If you want your gun safe to be the least exposed to the hottest area of the fire, don’t place it in your bedroom. The best place to set it up is the farthest corner of the house, closest to the walls where it’s away from burning items. Furthermore, it also helps your gun safe profoundly stay out of the fire from two sides. Apart from placing it in the corner of the house, consider placing it on the ground floor if you have a multi-story building.

Give it a concrete barrier

Getting your gun safe, a cement and concrete barrier can help it stay out of the fire as well. When you’re placing it on the farthest corner of the house, it already has two sides safe from the direct contact to the fire. The next thing you do is, take a measurement of the safe area and build a concrete wall with 3 to 5 cement layers. It will keep the fire directly touching the gun safe and melt or hit the exterior or interior of the safe.

Make a fire insolation

When the gun safe is safe from the fire from the outside, it’s time to pay attention to the interior. You should get a fire-resistant gun safe door if you’re up to a DIY build. The door is the most vulnerable place for the fire to get its way into the safe. You must keep the fire, heat, and smoke out of the safe and dissipate the heat to the ground and keep it from reaching the inside. Gypsum insulation insert can be a good way to dissipate the heat and keep it away from the internal of the safe.

Tips for Choosing a Good Quality Fireproof Gun Safe

The gun safe must be fireproof so that the paper documents, money in it stay safe if your house catches on fire. Here are the things you must consider when you’re shopping for a gun safe:

Tips for Choosing a Good Quality Fireproof Gun Safe

Know the threat

The first thing to consider is knowing why you’re getting the gun safe in the first place. If it’s only for keeping the gun, cash, and other precious items away from burglary, go for a thicker metal frame rather than a fireproof rating. A good fireproof gun safe doesn’t indicate its anti-burglary capability.

Fire rating

Fire rating for the gun safe can be the most important criterion to consider when choosing a gun safe. A house usually burns at 1200° F, where the paper starts burning at around 424° F and polymer guns at 480°. Be sure to check if the gun safe is capable of keeping the interior cooler than for at least 1-2 hours. If the safe has gypsum insulation inside, it’s a good sign of being good at fireproofing.

Does it do both?

If you have to keep the safe away from the thieves alongside a fireproof rating, that can be a big thing to ask for. A fireproof safe usually comes with a metal outer shell as thin as 16 to 18 gauge, which is too thin for the burglars. If you have to get both simultaneously, get heavier steel with a better lock mechanism with a fireproof rating.

Floor attachment

Would a safe be good enough if the burglars can pick it up and take the whole safe away? No! Ensure the safe has a strong base with floor attachment with which you can engrave it or some attachment. Be creative about it because the burglars also know how to pick it up despite the locks or attachments.

Lock mechanism

While selecting a fireproof gun safe, getting the right lock mechanism is more important than the regular times. Combination locks are great because of low maintenance and don’t require batteries, but they are slow at operation. Biometric locks can be good if you have multiple users and need tech in it; but, they need batteries. Electronic locks are great if you have a smart home solution; it will keep you updated if your safe is getting breached.

Frequently Asked Questions

Here are the most frequently asked questions about fireproofing a gun safe that you might find interesting for your project:

Where do you store fireproof safe?

If you have multiple stories in the building, it’s best to put the safe on the ground floor. For the best safety, please place it in the corner of the room where the outside walls will be closest to the safe.

Will paper money burn in a fireproof safe?
