Practice question

In what situation would a Level B protective suit be appropriate?

  1. When only air-purifying respirators are needed
  2. When skin protection is needed but not full respiratory protection
  3. When there is a low risk of contamination
  4. When working with gas under pressure

Answer: B — When skin protection is needed but not full respiratory protection

Level B protection is chosen when you need to guard the skin against chemical splashes or contact, while still using a respirator for inhalation hazards but without the fully vapor-tight, encapsulated suit of Level A. In this situation, skin protection is essential, but full respiratory protection from a completely sealed suit isn’t required, so a splash-protective clothing plus a high-level respirator provides the right balance. The other scenarios describe conditions where either respiratory protection alone would be enough, the risk is very low, or the hazard is severe enough to demand a more protective, vapor-tight suit.
