For a projectile with bursting smoke categorized as vt, which safety elements apply?

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

Answer: (B)

Understanding safety elements for a VT-coded bursting smoke projectile means recognizing all hazards that come with a time-delayed explosive payload plus smoke generation. This type of munition has high explosive filler and can cause fragmentation, so both the HE and frag hazards must be addressed. Movement is required to establish a safe standoff and ensure the item is handled away from personnel, and there is a potential fire risk from the smoke formulation, which may involve pyrotechnic materials such as white phosphorus. The VT classification signals a timed initiation, so the timing aspect must be treated as a controlled hazard. Electromagnetic effects and static discharge can influence initiators and sensitivity, so EMR and static safety considerations apply. The standard 1-hour water/watch time is a precaution used in handling procedures to verify stability under environmental conditions. The combination of HE, frag, move, fire, WP, VT, EMR, static, and 1hrwt reflects the most complete and appropriate set of safety elements for this item, whereas the other options omit one or more applicable hazards.
