Level B PPE is defined as

Level B PPE is defined as

• A. The highest level of protection.
• B. High respiratory protection with less skin protection than Level A.
• C. Used when airborne substances are known and appropriate filters are available.
• D. Standard work uniform with minimal protection.

Answer: (B)

Level B PPE is chosen when inhalation hazards are the primary concern and you need strong respiratory protection, but you don’t require the fully encapsulated skin protection of Level A. It provides a high level of respiratory protection—typically a respirator with full-face protection or a SCBA—while the outer clothing offers splash and chemical protection, not the complete, sealed, fully encapsulated suit used in Level A. This balance allows effective protection from airborne contaminants while giving the wearer more mobility and less encumbrance than Level A. In contrast, Level A would be used when dermal exposure and skin absorption are a major risk in addition to inhalation hazards, requiring a fully encapsulating suit with a positive-pressure SCBA. Level C involves known hazards with appropriate air-purifying respirators and less skin protection, and Level D is minimal protection, like standard work clothing.
