What does the M9 detector indicate?

What does the M9 detector indicate?

• A. Identifies the specific agent
• B. Indicates there is an agent present
• C. Measures the concentration
• D. Determines the agent's lethal dose

Answer: (B)

The M9 detector’s job is to show whether a chemical agent is present. It’s a quick, qualitative screening tool that changes color when it comes into contact with chemical agents, signaling that decontamination and further checks are needed. It does not tell you which agent is present, nor does it measure how much agent is there, and it cannot indicate lethal dose. So the best description is that it indicates there is an agent present.
