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

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

Answer: (A)

When handling a bursting smoke projectile, even though its primary effect is smoke, the device still carries hazards from a bursting charge and the materials inside. The highest-priority safety elements here come from the fact that there is a high-explosive bursting charge; that means a potential blast and fragmentation risk, so the presence of a high-explosive hazard and fragmentation hazard must be acknowledged. Because the burst can throw fragments and the smoke formulation may involve incendiary components, there is also a real fire risk and a potential white phosphorus component, which can ignite and cause severe burns. To manage these dangers, maintain distance and move away from the device area to reduce exposure to blast, fragments, and any heat or flame. Some smoke munitions use incendiary or phosphorus elements, so the WP hazard is specifically relevant. After a suspected or actual hazardous event, a waiting period is often recommended to allow residual hazards to subside before approaching or handling the item; this is the 1-hour waiting time. The option that aligns with these considerations includes high-explosive presence, fragmentation risk, movement for safety, fire risk, white phosphorus hazard, and the appropriate waiting time. Other options include hazards that don’t apply to this item—such as filler-ejection scenarios or electromagnetic/static hazards that aren’t part of this smoke projectile’s risk profile.
