Which scenario would trigger the use of respiratory protection?

• A. Exposures could be greater than permitted
• B. Exposures are well below limits
• C. There is no hazard
• D. For cosmetic reasons only

Answer: (A)

Respiratory protection is used when there is a potential inhalation hazard that could exceed safe limits. If exposure could be greater than permitted, a respirator helps reduce the amount of contaminant breathed in and protects health, especially when other controls can’t guarantee staying below limits. If exposures are well below limits or there is no hazard, a respirator isn’t needed. Cosmetic reasons or any non-hazard-related justification also don’t warrant respirator use.
