Level C protection differs from Level B in what way?

• A. Vapor tight, encapsulated single piece
• B. Regular station clothes
• C. Liquid splash protection, not vapor tight
• D. Liquid splash protection, usually non-encapsulated

Answer: (C)

Level C protection is chosen when the atmosphere can be managed with an air-purifying respirator and the skin protection is focused on splash protection rather than vapor containment. The key distinction is that the clothing used at Level C is not vapor-tight, so it does not seal against vapors. Instead, respiratory protection comes from cartridges on an air-purifying respirator, and the ensemble provides splash protection for the skin. This contrasts with Level B, which involves higher respiratory protection and a splash-protective suit, but does not rely on a fully encapsulated, vapor-tight environment. So the defining difference described here is liquid splash protection that is not vapor-tight.
