What is the safety for a projectile, HE with MT?

• A. He, Frag, Move, C/S
• B. He, Frag, Move, VT
• C. He, Frag, Move
• D. He, Frag, Move, Eject

Answer: (A)

Understanding the safety for a projectile with a high-explosive payload and a mechanical time fuze (MT) hinges on matching the hazards and the fuze type to the correct safety indicators. You always have the explosive hazard (HE) and the fragmentation hazard (Frag) to acknowledge. Move is included because you should put distance between people and the munition to reduce exposure during handling or transport. The MT designation brings in a specific safety requirement that relates to the mechanical timer fuze’s state or arming condition; that requirement is captured by the C/S designation.

A safety list that substitutes VT (variable time) or adds Eject isn’t appropriate for an MT fuze—the fuze type drives those different safety tags. Likewise, leaving out the MT-specific safety designation (C/S) would omit a necessary condition for MT-type devices. Therefore, the complete and correct safety set for a projectile with HE and MT is: HE, Frag, Move, and C/S.
