Which protective level corresponds to Level B Type 1?

• A. Level A
• B. Level C
• C. Level D
• D. Level B Type 1

Answer: (D)

The main idea is that PPE levels A through D describe the overall protection strategy, and Level B has its own subtypes that specify exact ensembles. Level B is used when the atmosphere requires respiratory protection and skin protection from hazardous materials, but does not require a fully encapsulated vapor-tight suit. Level B Type 1 is itself a Level B configuration, so the protective level that corresponds to Level B Type 1 is Level B Type 1 itself. This is distinct from Level A (fully encapsulated vapor-tight suit with SCBA), Level C (air-purifying respirator with splash protection), or Level D (work clothing).
