Which item is required for Level C protection?

• A. Escape mask
• B. Full-face air-purifying respirators
• C. Positive pressure SCBA
• D. Disposable outer boots

Answer: (B)

Level C protection centers on having a respirator that filters the air and protects the eyes, because the hazard is airborne and the concentration is known or controlled. A full-face air-purifying respirator delivers both respiratory protection and eye protection with a proper seal, using cartridges chosen for the specific contaminant. This matches Level C needs, where you rely on an air-purifying respirator rather than a fresh air supply.

An escape mask is intended for short, rapid egress and often does not provide the necessary seal or cartridge protection for ongoing work in a hazardous environment. A positive-pressure SCBA provides its own breathing air from a cylinder and is used for higher protection levels (Level A or B), not Level C. Disposable outer boots address foot protection but do not address respiratory or eye protection.

So, the item that fits Level C protection best is the full-face air-purifying respirator.
