In the MOPP system, which level provides the greatest protection?

• A. MOPP Level I
• B. MOPP Level II
• C. MOPP Level III
• D. MOPP Level IV

Answer: (D)

Protection increases with each step of the MOPP sequence, and the highest level provides the most protection because you wear the complete protective ensemble, forming the strongest barrier against chemical and biological hazards. At this level you don full protective clothing, a respirator or protective mask, hood, gloves, and boots, with the suit sealed to minimize skin contact and inhalation. Moving to lower levels means fewer items are worn and gaps in coverage appear, raising the risk of exposure. The highest level does come with more heat stress and reduced mobility, but it offers the greatest overall protection.
