Which option correctly describes Level C protection?

• A. Full or half-mask APR and Hooded chemical resistive clothing
• B. Hooded chemical resistive clothing with no respirator
• C. Fully encapsulated suit with SCBA
• D. Standard work clothing

Answer: (A)

Level C protection uses an air-purifying respirator combined with hooded chemical-resistant clothing. This setup provides skin and eye protection with a respirator that filters the air the wearer breathes, appropriate when the atmosphere has enough oxygen and the contaminants are known and can be filtered, not requiring a fully encapsulated suit or an open-circuit SCBA.

So the option describing a full- or half-face respirator (air-purifying respirator) with hooded chemical-resistant clothing matches Level C. The other scenarios either lack respiratory protection, require a fully encapsulated suit with SCBA, or use standard work clothing, which are not Level C.
