For a rocket with ejection and vt, which item is listed as a safety?

• A. vt
• B. jet
• C. fire
• D. pe

Answer: (A)

In this context, safety designators point to the condition or feature that keeps the system in a safe state during handling. For a rocket with an ejection system, the term that denotes a safe condition is the one used as the safety designation. That term is vt, so it represents the safe state or mechanism that prevents unintended activation. The other terms describe actions or hazards—jet implies a propulsion/egress action, fire is an ignition hazard, and pe indicates another energetic hazard. None of those describe a safety condition, so they’re not the safety designation. Therefore, vt is the appropriate safety item.
