Which of the following best defines a Non-Persistent Agent in chemical agent terms?

• A. A chemical agent that dissipates and/or loses its ability to cause casualties after 10-15 minutes.
• B. A chemical agent that remains in the environment for days and can cause long-term casualties.
• C. A chemical agent that cannot be detected by any sensor.
• D. A chemical agent that only damages equipment, not personnel.

Answer: (A)

Non-persistent agents are chemicals that do not linger in the environment; they dissipate quickly and lose their ability to cause casualties within a short period. The statement that they dissipate and lose potency after about 10–15 minutes captures this quick, temporary duration, which is the hallmark distinguishing them from persistent agents that remain in the environment for days. The other ideas don’t fit this concept: lingering in the environment for days describes persistent agents, not non-persistent ones; detection capability is about how the agent is sensed rather than how long it lasts; and affecting equipment rather than people misses the fundamental purpose of chemical agents and isn’t related to persistence.
