Are All Gun Safes Fireproof? Fire Ratings Explained

An In-Depth Look at ETL Fire Ratings

Time to read: 5 minutes

In the realm of firearm safety, one topic that often emerges is the fire resistance of gun safes. “Are gun safes fireproof?” is a question that reverberates in the minds of many gun owners. This is not surprising, considering the paramount importance of safeguarding our firearms not only from unauthorized access but also from unexpected threats such as fire.

However, the answer to this question is multifaceted. Not all gun safes are fireproof. The degree of fire resistance offered by a gun safe depends largely on its design, the materials used in its construction, and notably, its fire rating. While some gun safes can withstand high temperatures for extended periods, others may offer minimal fire protection.

This article delves deep into the concept of fire ratings, with a special focus on ETL fire ratings, which are a recognized standard in the industry. By understanding these ratings, you can make an informed choice when buying a gun safe, ensuring the best protection possible for your valuable firearms.

What Makes Gun Safes Fireproof?

To address this query straight off the bat – not all gun safes are fireproof. However, many high-quality gun safes on the market offer a significant degree of fire resistance. The level of fire protection depends on the safe’s design, materials, and most importantly, its fire rating.

Understanding ETL Fire Ratings

When discussing fireproof gun safes, it’s crucial to understand ETL fire ratings. ETL Intertek, an independent testing and certification organization, provides these ratings. They offer a reliable measure of a gun safe’s fireproof capabilities.

ETL fire ratings for gun safes are categorized based on the time a safe can withstand a specified temperature while keeping the internal temperature below a certain threshold (usually 350°F), thus protecting the safe’s contents. Here are the common ETL fire ratings:

ETL Verified Fire Endurance (30 minutes at 1200°F)

Safes with this rating can withstand a fire of 1200 degrees farenheight for 30 minutes.

ETL Verified Fire Endurance (90 minutes at 1200°F)

Safes with this rating can endure a fire of 1200 degrees farenheight for 90 minutes.

ETL Verified Fire Endurance (60 minutes at 1200°F)

Safes with this rating can endure a fire of 1200 degrees farenheight for 60 minutes.

ETL Verified Fire Endurance (120 minutes at 1200°F)

Safes with this rating offer the highest level of protection, withstanding a fire of 1200 degrees farenheight for 120 minutes.

Materials that Make a Gun Safe Fireproof

When it comes to the fire resistance of a gun safe, the materials used in its construction play a pivotal role. A combination of several materials working together contributes to the fireproof capabilities of a safe. Here are some key elements:

  1. Steel
    The outer shell of most high-quality safes is made of steel due to its strength and durability. However, contrary to popular belief, steel itself is not fireproof. In fact, at high temperatures, steel can warp and lose its structural integrity. Nonetheless, it serves as a robust protective barrier against external threats and forms the basis upon which additional fire-resistant layers are added.
  2. Fireboard
    Fireboard is a type of drywall specially designed to resist fire. It is made from non-flammable materials and typically contains a layer of gypsum, a naturally occurring mineral known for its excellent fire-resistant properties. Fireboard is often used in multiple layers within the walls, door, and ceiling of the safe to increase fire resistance. The number of layers of fireboard can significantly impact the fire rating of a safe.
  3. Composite Material
    Some manufacturers use a composite material, a mix of several fire-resistant substances, as an added layer of protection. This material is often sandwiched between the steel layers and acts as an effective insulator against heat.
  4. Door Seals
    Fireproof safes are also equipped with expandable door seals. These seals remain dormant under normal conditions but expand significantly in the presence of heat, sealing the door’s gap to prevent hot smoke or fire from entering the safe.

It’s important to note that while these materials can make a safe fire-resistant, no safe is entirely fireproof. The term ‘fireproof’ is more accurately understood as fire-resistant since these materials slow the penetration of heat into the safe, buying precious time to safeguard the contents in the event of a fire.
