Find a suitable place

Having fireproof gun safe is not the only solution. Most important part of fireproofing a gun safe is to find a suitable place. Try to put your gun safe in basement on concrete floor or slab so that fire could not catch from the bottom. Keep the other items away from gun safe for extra security.

However, if you haven’t got basement then keep it in a place that is secured and isolated. Don’t put your safe on wooded floor or weaker floor that is easily vulnerable. If your gun safe is heavy don’t put it on upper floor as it can be fallen through the floor during extreme level for fire.

Put a soft rubber mat or carpet under the gun safe

Bottom of the safe is susceptible to moisture especially when it gets touched with hard materials like concrete, wood and slab. To get rid of moisture and rust at the bottom of the safe, you should use soft rubber mat and carpet underneath the gun safe.

Keep flammable materials away from gun safe

Keep flammable materials and wooden items away from your gun safe. Gasoline, hand sanitizer, turpentine, paint thinner, aerosol can, non dairy creamer, linseed oil, rubbing alcohol, nail polish, nail polish remover and gun cleaning copper solvent all are flammable. So, don’t keep these flammable items near to your gun safe even if it’s fireproof.

Keep bullets outside the guns

You might be thinking about having bullets inside the gun cannot be a reason for fire as long as you pull the trigger. Unfortunately, pulling a trigger might not be required if changes in air pressure, especially when atmosphere is so warm, causes a bullets to be released.

During the time of fire if surrounding of the gun safe gets very warm there is a high possibility of releasing bullets accidentally. Another reason is your gun’s safety. Keeping bullets outside the guns help ensure safety of your firearms.

Use flame retardant insulation

Insulator has the power to keep the temperature normal especially when you use it inside the gun safe. Use as much insulation as possible inside the gun safe so that temperature during the time of fire remains under control. Make sure your insulation fits perfectly inside the safe. You can cut insulation with hacksaw and glued against the wall of the gun safe.  

However, the most important thing is that insulation must be flame retardant otherwise all of your effort turns out to be failed. You can use 5/8 inches drywall, gypsum board, at the exterior part of the gun safe.

Gypsum board is considered to be one of the best flame retardant insulators. Thick drywall will not protect fire for long time. You can purchase drywall from any hardware shop near to you.

Prevents moisture and rust

Excessive moistures help produce rust and mold within the gun and gun safe. Rust and mold in the long run damage and weaken the gun as well as gun safes. Therefore, if there is a fire incident, it could easily attract the weaker point of the guns. This eventually reduces the effectiveness of fire protection.

So, we would like to recommend you to use a moisture absorber for gun safes to keep the moisture out of the safe and increase the effectiveness of the fire protection.
