For a projectile with ejection categorized as et, which safety elements apply?

• A. He, frag, move, eject (filler), 1hrwt
• B. He, frag, move, eject (filler), c/s, emr, static, 1hrwt
• C. He, frag, move, fire, wp
• D. He, frag, move, eject (filler), c/s

Answer: (B)

When a projectile has an ejection mechanism (et), you must account for hazards from both the main explosive body and the ejection process itself, plus the environmental and handling factors that can influence safety. The safest and most complete set of safety elements includes the high-explosive hazard and the fragmentation risk, the need to control movement during handling, and specifically the hazard from the ejection of filler. It also requires safety controls or supervision (c/s), consideration of electromagnetic radiation (EMR) and the risk of static electricity, and a designated waiting time (1hrwt) to let conditions stabilize before further handling. This combination covers the primary explosive risk, the debris and secondary hazards from ejection, the electrical/static considerations that can affect sensitive components, and timing safety. Other options miss one or more of these hazards or introduce elements (like fire or WP) that aren’t inherent to ET ejection unless those materials or conditions are present.
