How do Level B and Level C PPE differ?

How do Level B and Level C PPE differ?

• A. Level B provides higher respiratory protection with SCBA and splash-protective clothing but not full encapsulation; Level C uses a PAPR or elastomeric respirator with protective clothing.
• B. Level B uses PAPR; Level C uses SCBA.
• C. Level B and Level C are identical.
• D. Level B is fully encapsulated; Level C is not.

Answer: (A)

In this topic, the key distinction is how the respiratory protection and skin protection are combined at each level. Level B uses a self-contained breathing apparatus, which provides the highest level of respiratory protection because the air supply is independent of the surrounding environment. The splash-protective clothing worn with Level B shields the skin from splashes, but the suit isn’t fully encapsulating the wearer. Level C, on the other hand, relies on air-purifying respirators such as a PAPR or elastomeric respirator, with chemical-resistant clothing that is not sealed around the body. This means respiratory protection is lower than with an SCBA and depends on the surrounding air having enough oxygen and the contaminants being filterable. So Level B offers maximal respiratory protection with SCBA plus splash protection, while Level C uses AP respirators with protective clothing, but without full encapsulation.
