What is the safety for a projectile with HE and ET?

• A. He, Frag, Move, C/S, EMR, Static, 1hrwt
• B. He, Frag, Move
• C. He, Frag, Move, VT, EMR
• D. He, Frag, Move, Eject

Answer: (A)

When a projectile contains high explosive (HE) and an external timing device (ET), you must account for multiple hazards at once: the explosive energy and the potential for fragmentation, plus sensitivities related to the external timing system. The safety listing should reflect the explosive content (HE) and the fragmentation hazard (Frag) because either condition can create dangerous debris and a detonation risk. Movement is allowed only under controlled conditions, which is why Move appears. The ET setup brings electrical and EMI/Electromagnetic Radiation concerns and potential static sensitivity, so EMR and Static are included to warn about those risks. The 1hrwt (one-hour waiting time) indicates a necessary stabilization period before handling due to the sensitive timing device. The C/S tag shows the item’s controlled status under these circumstances. Together, this combination provides the most comprehensive and appropriate safety profile for an HE projectile with ET, covering the explosive, fragmentation, handling, electrical, and timing considerations. The other options miss one or more of these critical hazards or safeguards, making them less complete for this scenario.
