Primer-Fuze Magazine must restrict storage to which classes?

• A. 1.3 only
• B. 1.2.2, 1.3 (except rockets and rocket motors), and 1.4 A&E
• C. 1.2.2 only
• D. 1.1, 1.2, 1.3

Answer: (B)

Primer-Fuze Magazine storage is designed to limit explosive risk to manageable levels by allowing only items that do not present a mass-explosion hazard. The best choice includes classes 1.2.2, 1.3 (excluding rockets and rocket motors), and 1.4 A&E because these categories represent limited or non-mass-explosion hazards that can be safely grouped in a controlled magazine.

Class 1.2.2 covers items that may have projection or fragmentation hazards but do not cause a large, widespread blast. This keeps the potential energy release contained. Class 1.3 includes fire-related hazards that could lead to a smaller or less severe explosion, still within a controlled setting, but rockets and rocket motors are left out due to their different and typically higher hazard profile. Class 1.4 A&E encompasses minor explosion hazards associated with ammunition and explosives in a way that is compatible with the limited-risk environment of a primer-fuze magazine.

Choosing these classes, rather than including higher-hazard categories, minimizes the consequences of a mishap while still accommodating the types of items stored in primers, fuzes, and related components.
