Which description correctly outlines PPE Level A through Level D and their typical field uses in disaster response?

• A. Level A is splash protection with SCBA.
• B. Level B: air-purifying respirators with protective clothing.
• C. Level C: basic work attire.
• D. Level A: fully encapsulated suit with SCBA; Level B: splash protection with SCBA; Level C: air-purifying respirators with protective clothing; Level D: basic work attire; selection based on hazard assessment.

Answer: (D)

PPE levels are arranged to match the level of hazard discovered in the field, with the choice guided by a hazard assessment. The description that matches this framework states that Level A is a fully encapsulated suit with SCBA, Level B provides splash protection with SCBA, Level C uses air-purifying respirators with protective clothing, and Level D is basic work attire, with the level selected based on the hazard. This reflects the standard progression: maximum protection when vapors or unknown hazards are present (fully encapsulated suit plus SCBA); still high respiratory protection but with splash protection for skin when the hazard is less about skin absorption or the suit need not be fully encapsulated; air-purifying respirators with protective clothing for known or lower-risk airborne contaminants; and minimal protection for tasks with no chemical hazard. The emphasis on hazard-based selection is central to using PPE effectively—protecting responders while maintaining mobility and situational awareness.
