For a rocket with bursting smoke and VT, which item is listed as a safety?

• A. jet
• B. chem
• C. vt
• D. pe

Answer: (C)

Focus on how safety labeling works for pyrotechnic rockets. In a rocket that uses bursting smoke, the safety listing identifies the timing or arming feature that governs when the burst will occur. VT stands for Variable Time, a timed fuse that provides a controlled delay between arming and bursting. This delay is the safety aspect because it ensures the device doesn’t explode immediately and can be handled and deployed with a predictable, set timing. The other terms describe effects or hazards (a jet effect, chemical hazard, or percussion element) rather than a timing safety mechanism, so they aren’t the safety item in this context.
