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

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

Answer: (D)

The key idea is that a rifle grenade with burning smoke and a striker release carries multiple hazards at once, so the safety annotation must reflect all of them. High explosive content (He) means there’s a real detonation risk and potential for dangerous fragmentation (Frag) if the device ruptures. The burning smoke introduces a fire hazard (Fire) and a chemical/smoke hazard (C/S) to anyone nearby. The striker release adds the possibility that heat or the burning process could trigger an unintended ignition, so you must account for that risk as well. Because of the striker mechanism, a waiting period is typically specified to let the burning process stabilize and minimize the chance of a delayed ignition or sudden ignition if disturbed. That waiting time is represented as 1Hrwt (one hour wait time). So the best safety profile is the one that includes He, Frag, Move, Fire, C/S, and 1Hrwt, covering the explosive and fragmentation hazards, the fire and smoke/chemical hazards, the need to relocate away from the device, and the required wait time before approaching or handling. Other options omit one or more of these critical hazards or include hazards not applicable to this device, making them less accurate.
