What single item distinguishes Level B from the lower PPE levels?

• A. Vapor-tight suit
• B. Boots
• C. Gloves
• D. SCBA

Answer: (D)

Respiratory protection with a self-contained breathing apparatus is what sets Level B apart from the lower levels. Level B provides splash protection and chemical-resistant clothing, but crucially it uses an SCBA to protect the wearer’s breathing in potentially hazardous or oxygen-deficient atmospheres. Boots and gloves are common across multiple levels, and a vapor-tight, fully encapsulating suit is associated with Level A, not Level B. So the SCBA is the defining feature that differentiates Level B from the lower PPE levels.
