Which level of PPE uses a full or half-mask APR and hooded chemical resistive clothing?

• A. Level C protection
• B. Level A protection
• C. Level B protection
• D. Level D protection

Answer: (A)

Level C protection is defined by using an air-purifying respirator, which can be a full-face or half-face mask, along with hooded chemical-resistant clothing. The respirator filters contaminants from the air, while the hooded suit protects the skin and head from splashes and contact with chemicals. This combination is chosen when the atmosphere isn’t immediately dangerous to life or health and can be adequately protected by filtration rather than by an air-supply or fully encapsulating suit. The other levels require different configurations: Level A uses a fully encapsulating suit with a self-contained breathing apparatus, Level B uses splash protection with a SCBA or other SCBA-equivalent respiratory protection, and Level D is basic work attire with minimal protection. So the described gear matches Level C.
