Which description matches Level A protective suits?

Which description matches Level A protective suits?

• A. Vapor tight, encapsulated single piece. SCBA or SAR
• B. Liquid splash protection, usually non-encapsulated, single or two piece. SCBA or SAR
• C. Liquid splash protection, not vapor tight, APR, PAPR or Particulates mask
• D. Regular station clothes, no breathing protection

Answer: (A)

Level A PPE provides the highest level of protection in hazardous atmospheres. It uses a fully encapsulated, vapor-tight suit that covers the entire body, preventing vapors, gases, and liquids from contacting skin or entering the suit. Because the atmosphere may contain toxic vapors, breathing air must come from a life-support system rather than a filter—hence the requirement for a self-contained breathing apparatus or a supplied-air respirator. The other descriptions describe systems that are not vapor-tight or not fully encapsulated, or just regular clothing with no breathing protection, which would not protect against vapor hazards. This combination—vapor-tight, encapsulated suit with SCBA or SAR—best matches Level A.
