Are Ammo Cans Fireproof?

Ammunition is a fire hazard, and appropriate handling, especially around a fire, is crucial. Proper storage practices are essential to keep them away from extreme temperatures. One may be tempted to think that ammo cans are fireproof, but there are several factors to consider.

The ammo cans are one of the best options to consider at a pocket-friendly price. They are also suitable for traveling with ammo. However, they might not be suitable for extreme temperatures. Some cans are also airtight, but this quality does not render these ammo cans fireproof.

Is Live Ammunition Dangerous?

The chances are that you will not recover your ammunition in case of a fire. Your ammo cans fireproof qualities will not matter. The heat in the can will set off the ammunition since the ammunition gains heat very fast.

The bullets are heavy, but the casings will explode and damage objects nearby. The explosion can also injure any person close to the safe when the cases explode.

The powder present in the ammunition will also emit smoke and other gases that expand. The expansion is effective under low pressure. The powder attains high temperatures, which makes the fireproof cans burn from inside.

The cool air inside the cans also depletes as your ammo explodes. Hot air and smoke will also sip in the safe, making it hard for the safe to cool.

The heated gunpowder in the safe will act as a bomb and pose more danger. Therefore, a safe made of insulating material can be a good option. The safe should also allow for easy ventilation.

In case of a fire outbreak, the safety of your ammunition in the safe will depend on:
