In what situation is a level B HazMat suit typically used?

A level B HazMat suit is specifically designed for situations where a high level of respiratory protection is necessary due to the presence of hazardous materials, while simultaneously addressing a lower but still significant risk of chemical exposure to the skin. This type of suit typically consists of a chemical-resistant outer layer and provides the wearer with an SCBA (Self-Contained Breathing Apparatus) for adequate respiratory protection.

In scenarios where there are known airborne contaminants that require breathing protection, but the risk of skin exposure to hazardous substances is lower, a level B suit would be appropriate. This allows responders to safely engage with the materials while minimizing health risks associated with inhalation.

In contrast, the other choices do not accurately represent the situational requirements for using a level B suit. For example, a situation with high chemical exposure risk would necessitate a different level of suit, and the use of no protective gear would clearly not align with safety protocols in HazMat operations.
