Gun safes do not offer enough protection against fire. You can fireproof the interior of a gun safe as well as adding additional fireproof protection for the gun inside. You will need some hardware and gun shop supplies. You will also need a few items from a pharmacy that can be purchased over the counter. Your fireproofed gun safe will help to protect your gun from a house fire until the fire department shows up.
Open the gun safe. Remove the gun from inside of the gun safe. Place a trigger guard on the gun. Put the gun away in a safe and hidden location.

Apply bonding glue liberally to the top, bottom and sides inside of the gun safe.
Push the fireproof gypsum tiles against the bonding glue. Let the bonding glue set for 24 hours.
