Which statement correctly describes Level B PPE?

• A. Level B PPE Is The Highest Level Of Respiratory Protection
• B. Level A PPE Provides Highest Skin, Eye, And Respiratory Protection; Used For Unknown, Highly Hazardous Aerosols
• C. Level C PPE Provides The Same Air Protection With Coveralls
• D. Level D PPE Represents No Protection

Answer: (B)

PPE levels are about balancing protection for the lungs versus protection of the skin and eyes in hazardous environments. Level B emphasizes the strongest respiratory protection available in the field, using an atmosphere-supplying respirator such as a supplied-air respirator or a powered air-purifying respirator. The tradeoff is that skin and eye protection are not as extensive as with Level A; the suit is typically not fully encapsulating and relies on splash protection rather than a complete seal.

This setup is used when the respiratory hazard is high or unknown, but there isn’t a need for the fully encapsulating, skin-protective suit that Level A provides. In contrast, Level A offers the most comprehensive protection for skin, eyes, and respiratory tract with a fully encapsulating suit and SCBA; Level C uses air-purifying protection with chemical-resistant clothing; Level D represents minimal protection.
