What is the safety for a rifle grenade, bursting smoke, striker release?

• A. He, Frag, Move, Fire, Wp
• B. He, Frag, Move, Fire, Wp, C/S
• C. He, Frag, Move, Fire, Wp, C/S, 1Hrwt
• D. He, Frag, Move

Answer: (C)

When handling a rifle grenade that is set to burst smoke and has a striker release, you must recognize multiple simultaneous hazards. The device contains a high-explosive (HE) main fill, so there is a real detonation risk if the fuze is armed or disturbed. Detonation would also produce dangerous fragments, so a fragmentation hazard is present. The striker release means the fuze can be triggered, making the weapon an arming and active-detonation risk during handling or movement. The smoke component often involves white phosphorus or other smoke agents, which introduces incendiary and chemical hazards as well as a specific inhalation risk to anyone nearby. This creates a chemical/smoke hazard that must be accounted for. The safety assessment also includes environmental factors like a wind test to understand how the smoke plume will disperse, hence the one-hour wind test requirement. Because all these hazard types apply to this scenario, the comprehensive safety listing that includes high explosive (HE), fragmentation (Frag), movement (Move), firing (Fire), white phosphorus (Wp), chemical/smoke (C/S), and the one-hour wind-test (1Hrwt) best captures the full risk profile.
