In a situation where you expect to encounter airborne hazardous substances, but don't need skin protection, what level of full-body protection will you need?

Full-body protection specifically designed for situations involving airborne hazardous substances is crucial for maintaining safety in the workplace. Level B protection is appropriate in this scenario because it provides a high degree of respiratory protection while still allowing for some flexibility and comfort when full skin protection is not necessary.

Level B involves wearing respiratory protection that is of a high standard (such as a self-contained breathing apparatus) along with protective clothing. This level is used when the hazards are known, and air monitoring shows that respiratory protection is needed but skin protection may not be required.

In contrast, Level A involves a totally encapsulating suit that provides the highest level of protection against both vapors and particles, which would be excessive in this situation since skin protection is not necessary. Level C is less stringent in terms of respiratory protection and is used when contaminants are identified and the airborne concentrations are known to not exceed levels that require a higher level of protection. Selecting “No protection needed” would not address the expected presence of airborne hazardous substances and would put the individual at risk.
