How many MOPP levels exist and what do they signify?

• A. Levels 0 through 4 define escalating PPE and decon procedures.
• B. Levels 1 through 3 with no 0.
• C. A single level.
• D. Levels 0 through 4 with no change in PPE.

Answer: (A)

Five levels exist, numbered 0 through 4. They represent escalating protection and decontamination requirements in response to chemical, biological, radiological, and nuclear threats. Level 0 means normal operations with no special protective gear. As the threat increases, you move up the ladder, adding progressively more protective equipment and preparing for the appropriate decontamination procedures at that level, up to Level 4, which uses full protective gear and full decon readiness for the most hazardous conditions. The other options don’t fit because they either omit Level 0, propose only a subset of levels, claim there’s a single level, or say PPE doesn’t change across levels.
