Buying Guide for Fireproof Gun Safe

Gun Safes that are made to protect your items against buglers cannot give you fire-resistant protection. Steel construction is not enough to protect against fire. It needs a special fireproof coating to help you prevent from maximum damage. For buying a product with dual protection, you need to understand what can make a safe fire resistant and what are the approved ratings for better protection.

Fire Resistant Ability

No gun safe can be fireproof, so this term is misleading for the costumers. A gun safe can be fire-resistant for a specific period of time. It should be 1 hour, at least according to U.L. fire ratings. Underwriters Laboratories (U.L.), a U.S. authority on safes for both security and fire protection.

There must be a fire seal on the door, this will not only give protection against fire, smoke, and moister, but it will also help to maintain your contents from rust and corrosion. A reliable seal will not even let the fire extinguishing spray into the safe by expanding its size and keep the contents safe.

Managing the Contents

The most significant question is what are you going to place in your safe. Most of the cases, users put their other valuables as well with their guns that can be a good idea for a budget-friendly approach as long as you don’t think about emergencies other than thieves.  Every material has its own life when it is exposed to a higher level of heat. Paper-like cash, personal data like documents, DVDs, C.D.s, or photos of your family, jewelry, etc. can be fit in with guns in the safe.

House on fire generally can have a temperature in 800 to 1200 degrees, and mostly safes are engineered to keep the inner temperature near 350 degrees, and after that paper and wood can start discoloring. The paper will autoigniting at 415 degrees. In the process of maintaining temperature, safe will create moisture that also damages most of the contents.

U.L. rated small safe for documents, and other valuables can be put inside the gun safe for greater protection against fire.

Placement of the Gun Safe

Placing a gun safe on the floor with holes can be a good idea to secure it from intruders, but for fire protection, it can be more prone to damage. You can have a wall safe to mount it on the wall as doors of the floor safes are exposed with no fire board to dissipate the heat. You can hide your safe to give it more security, but it should be easily accessed able in emergencies.

Locking Mechanism

In the fire-resistant gun safe, you can have both mechanical or electronic locks. Mechanical locks should be adequately maintained as advised by experts it should be serviced by technicians after every five years. Electronic locks can work well while managing the batteries. Some of the safes have both the options to facilitate their users to access the safe easily and manage the contents more securely.
