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

• A. He, Frag, Move, 1hrwt
• B. He, Frag, Move
• C. He, Frag, Move, 1hrwt
• D. He, Frag, Move, C/S

Answer: (C)

Handling a projectile that is high-explosive and has a time-delay fuse requires recognizing both the explosive/fragility hazards and the specific handling step that the fuse demands. The projectile presents both an HE charge and fragmentation risk, so any movement or disturbance can cause a dangerous release of energy and flying fragments. Because the fuse is time-delayed (PTTF), there is a potential for initiation if the munition is handled too soon or improperly. To reduce that risk, the standard safety action is to allow a defined waiting period and then relocate the item only after that period has elapsed, rather than handling it immediately in place. This is why the safe status includes HE, Frag, Move, and a one-hour waiting time. The waiting period (1hrwt) ensures the fuse remains inert or stabilizes and reduces the chance of an unexpected detonation during subsequent handling. The other options omit the required waiting time or add designators that aren’t part of the standard safety sequence for this item, making them less appropriate.
