In Level B, Type 2 configurations, which statement represents a limitation?

• A. SCBA is worn inside a fully encapsulating suit
• B. SCBA is exposed to the atmosphere without protection
• C. Belts and harnesses are always chemically compatible
• D. Facepiece compatibility always equals suit compatibility

Answer: (B)

In Level B, Type 2 configurations the focus is on skin splash protection while the suit does not fully encapsulate the wearer. The main limitation here is that the SCBA is exposed to the surrounding atmosphere without the encapsulating barrier that would shield it from potential contaminants. If vapors, liquids, or other hazards contact the SCBA or its connections, the respiratory protection can be compromised, which is a real weakness of this setup. The other statements describe configurations or assumptions that don’t capture this key limitation. Wearing the SCBA inside a fully encapsulating suit would be characteristic of a higher level of protection, not a Level B Type 2 setup. Belts and harnesses being assumed to be always chemically compatible is an overreach because compatibility isn’t guaranteed and must be verified. Likewise, assuming that facepiece compatibility always matches suit compatibility ignores interface realities where the two don’t line up perfectly.
