Which MOPP level corresponds to a “suspected threat”?

Which MOPP level corresponds to a “suspected threat”?

• A. MOPP-0
• B. MOPP-1
• C. MOPP-2
• D. MOPP-3

Answer: (B)

The concept here is how protective postures scale with threat level. When there is a suspected CBRN threat, you don’t stay in normal conditions—you start protective actions at the first stepped-up posture. This level is chosen because it provides baseline protection while you assess the situation, reducing exposure without jumping immediately to full protection. You then escalate to higher levels (up to full protection) if the threat becomes more certain or imminent. In short, suspected threat → begin at the first protective posture, then increase as needed.
