Explosives storage

Tread has been building ATF-approved explosives storage magazines for the last 50 years with safety and reliability always being at the forefront of our manufacturing process. When your operation requires the storage of explosive materials, the Tread series of magazines are industry-recognized and respected for their design features, quality construction, and structural integrity.

We offer type II, III, and IV magazines of multiple shapes and sizes.

Each Magazine is individually manufactured to meet or exceed the rigid government specifications established by the Bureau of Alcohol, Tobacco and Firearms, MSHA, and IME regulations and/or guidelines.

Types and Requirements

High explosives, upon initiation, function by detonation, a rapid decomposition (explosion) of the material caused by a shock wave moving through the product at a rate faster than the speed of sound. High explosives, such as blasting caps, detonating cord, dynamite, shaped charges, boosters, etc., must be stored in:

Type-I permanent magazines;

Type-II mobile and portable indoor/outdoor magazines; or

Type-III magazines for attended storage.

Low explosives deflagrate producing a large volume of heated gas. Low explosives, such as black powder, most display fireworks, safety fuse, igniters, igniter cord, fuse lighters, etc., must be stored in:

Type-I, -II, or -IV permanent, portable or mobile indoor/outdoor magazines.

Blasting agents are a material or mixture consisting of fuel and oxidizer that is intended for blasting and that cannot be detonated by a No. 8 test blasting cap when unconfined. Blasting agents may be stored in:

Type-V permanent, portable, or mobile outdoor/indoor magazines (minimum requirement).

Blasting Agents stored with high explosives must be stored in a Type I or IV magazine.
