Ammo cans, those ubiquitous metal boxes used for storing ammunition, are often perceived as fireproof. However, the truth is more nuanced. While they offer a degree of fire resistance, they are not truly fireproof. This article will delve into the specifics of ammo can fire resistance, explore the factors affecting their performance in a fire, and offer safer alternatives for storing ammunition and valuable items.
Understanding the Materials and Construction of Ammo Cans
Most ammo cans are constructed from steel, sometimes with a powder-coated finish. Steel itself has a relatively high melting point, typically around 2,500°F (1370°C). This high melting point contributes to their resistance to lower-intensity fires. However, the type of steel, thickness of the steel, and the presence of any protective coatings significantly impact their performance in a fire. Thinner steel cans will deform and melt at much lower temperatures than thicker gauge steel.
Factors Affecting Fire Resistance:
-
Steel Gauge: Thicker steel (higher gauge number, e.g., 16-gauge) offers superior fire resistance compared to thinner steel (lower gauge number, e.g., 20-gauge). The thicker the steel, the longer it will take for the heat to penetrate and weaken the container.
-
Powder Coating: While powder coating improves the appearance and corrosion resistance of the can, it doesn't inherently enhance its fire resistance. In fact, at high temperatures, the powder coat may burn off or release harmful fumes.
-
Seal: The seal on the ammo can is crucial for maintaining its contents' integrity during a fire. A compromised seal could allow for smoke and heat damage to the contents even if the can itself remains largely intact.
How Ammo Cans Perform in a Fire
The performance of an ammo can in a fire depends largely on the intensity and duration of the fire. In a low-intensity fire with moderate temperatures, an ammo can might offer sufficient protection to prevent the contents from catching fire. However, in a high-intensity fire, the steel can become weakened, deform, or even melt, exposing the contents to the flames.
Case Study: A Controlled Burn Test
While comprehensive, publicly available data on ammo can fire performance under controlled conditions is limited, anecdotal evidence and practical experience suggest the following:
-
Low-Intensity Fire (e.g., small bonfire): The ammo can might survive with minimal damage, although some discoloration or warping could occur. The contents would likely remain relatively protected.
-
High-Intensity Fire (e.g., house fire): The can could potentially melt, warp significantly, or even rupture, leaving the contents vulnerable to the fire.
Are Ammo Cans Fireproof for Valuables?
While ammo cans provide some level of protection, they shouldn't be considered a reliable fireproof solution for storing important documents, photos, or other valuables. True fireproof safes and storage solutions are designed to withstand far higher temperatures for extended periods. These safes are built with specialized materials and fire-resistant insulation.
Alternatives for Fireproof Storage:
For crucial items requiring fire protection, consider these options:
-
Fireproof Safes: Specifically designed to withstand high temperatures for a significant duration. They are rated by fire resistance testing organizations to indicate the level of protection offered.
-
Fireproof Filing Cabinets: Similar to fireproof safes but designed for storing documents and files.
Conclusion: Ammo Cans and Fire Safety
Ammo cans offer a degree of protection against moderate heat and flames, but they are not fireproof. Their effectiveness in a fire depends on the intensity and duration of the fire and the specific construction of the can. For critical documents, valuables, and other items requiring superior fire protection, investing in a fireproof safe or similar storage solution is recommended. Always prioritize safe and responsible ammunition storage, following all relevant local laws and regulations.
