What does MOPP level 4 consist of?

• A. JSLIST, boots, mask, and gloves worn
• B. JSLIST worn; boots, mask, gloves not worn
• C. JSLIST and boots worn; mask and gloves available
• D. JSLIST, boots worn; mask worn; gloves available

Answer: (A)

MOPP level 4 means you wear the full protective ensemble for chemical threats: the JSLIST suit, boots, the protective mask, and protective gloves all worn. This is the highest level of protection, designed for the most dangerous contamination conditions, even though it also increases heat and bulk. The other options describe not wearing one or more pieces or merely having them available, which isn’t consistent with level 4.
