Which safeties apply to a hand grenade with burning smoke and pull friction?

• A. HE, Frag, Move, 1hrwt, Fire
• B. HE, Frag, Move
• C. None
• D. HE, Frag, Move, Eject

Answer: (A)

When a hand grenade shows burning smoke and a pull-friction mechanism, there is a real risk that the device is armed and could detonate, or at least shed fragments and cause a fire. That means several hazards must be acknowledged at once: high explosive potential, fragmentation risk, the need to move away to a safe distance, and consideration of time and fire safety. The correct safety set reflects all of those concerns. High explosive and fragmentation are about what could happen if the device detonates or fails catastrophically, so both must be accounted for. Moving away reduces exposure to a possible blast or flying fragments. The 1hrwt element represents a time-based precaution related to the device’s arming or delay characteristics, ensuring you do not approach or manipulate it too soon. Fire safety is important because burning smoke and the fuse can ignite flammable material in the area, presenting another danger even if a full detonation does not occur. Other options omit one or more of these critical hazards—for example, neglecting fire risk, or the time/delay consideration, or the need to retreat to safety—so they don’t provide the comprehensive precaution needed for a potentially armed, burning device.
