PPE Level B ensemble is used when the type and atmospheric concentration require high respiratory protection but skin protection is less critical.

• A. Level A ensemble
• B. Level B ensemble
• C. Level C ensemble
• D. Level D ensemble

Answer: (B)

PPE selection hinges on whether the hazard is mainly in the air or mainly on the skin. When you’re dealing with a hazardous airborne contaminant and you need the strongest breathing protection, but the skin exposure isn’t as critical, a Level B ensemble is used. It provides the highest level of respiratory protection through a self-contained breathing apparatus, while offering splash and chemical protection with a non-encapsulating, chemical-resistant suit and gloves. The skin protection isn’t as demanding as it would be with a fully encapsulating suit, which is why Level A isn’t chosen here. Level A would be reserved for scenarios with severe dermal as well as inhalation hazards, requiring a fully encapsulated suit. Level C uses a less protective respirator (not SCBA) with splash protection for situations where the airborne hazard is present but not as extreme, and Level D is basic work attire with minimal protection when no hazardous materials are present.
