Which MOPP level provides the greatest level of protection?

• A. MOPP Level 4
• B. MOPP Level 1
• C. MOPP Level 2
• D. MOPP Level 3

Answer: (A)

Protection increases with the amount of protective gear you wear against chemical or biological hazards. The highest protection comes from wearing the full protective ensemble, which includes the outer protective suit, a sealing mask, gloves, boots, and the hood. With all these components in place, the barrier between you and the hazard is maximized, reducing skin exposure, eye exposure, and inhalation risk. This level is used in heavily contaminated environments, though it also limits movement and worsens heat stress, so it’s applied when the threat is significant.
