Which PPE ensemble provides the highest level of protection and includes a totally encapsulating suit with SCBA?

• A. Level B ensemble
• B. Level C ensemble
• C. Level A ensemble
• D. Level D ensemble

Answer: (C)

Level A provides the highest level of protection because it combines a totally encapsulating chemical protective suit with a self-contained breathing apparatus. The fully sealed suit prevents chemicals from contacting the skin, while the SCBA supplies clean air from an independent source, so breathing isn’t affected by the contaminated environment. This combination is used when hazards are unknown or highly toxic and there’s a real risk of skin contact, immersion, or inhalation. Other levels offer strong protection but not the same full encapsulation and independent air supply: Level B uses strong respiratory protection with clothing that isn’t fully encapsulating; Level C relies on air-purifying respirators with non-encapsulating clothing; Level D is basic work attire with minimal protection.
