Which MOPP level is associated with an “imminent threat”?

• A. MOPP-0
• B. MOPP-1
• C. MOPP-2
• D. MOPP-4

Answer: (D)

When a chemical or biological threat is imminent, you must have the highest level of protection. That is MOPP-4, which means donning the full protective ensemble—coat and trousers, hood, gloves, boot covers, and the gas mask. This level is used when the threat is about to impact personnel or is detected, so you need complete protection to operate safely in a contaminated environment. The lower levels provide progressively less protection and are used when the threat is less imminent, so they don’t fit the scenario described.
