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

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

Answer: (B)

For a projectile that bursts and releases smoke, you focus on the hazards created by the bursting action and the resulting effects, then apply safety elements that directly address those hazards. The bursting can produce fragments, heat, and possibly ignition effects from the smoke charge, and there may be explosive or propellant components associated with the device. So you include high-explosive content (to account for the energetic fill that could contribute to fragmentation or secondary hazards), fragmentation (to protect against flying debris when the item bursts), and the basic precaution to move away to a safe distance. In addition, you account for fire risk from the pyrotechnic smoke charge and any warhead/propellant-related hazard (wp) that might be present. These five elements together cover the primary dangers inherent to a bursting-smoke projectile of this type.

Other listed factors like ejecting filler, certain environment-related or test-specific elements (emr, static, 1hrwt, vt) aren’t directly applicable to the standard safety considerations for this pd-category item, so they’re not included in the best answer.
