Which statement best describes when a respirator must be used?

• A. Only air monitoring determines wearer
• B. When you require the use of a respirator for any reason, for any duration
• C. Only during emergencies
• D. Never

Answer: (B)

The main idea is that respiratory protection is required whenever the hazardous exposure has been identified as needing protection through the program’s hazard assessment. When the program determines that a respirator is needed, it must be worn for the entire time the hazard is present or during the portion of the task that creates exposure. Air monitoring provides data about exposure levels, but it doesn’t by itself mandate respirator use; the decision comes from the hazard assessment and the Respiratory Protection Program. Respirators aren’t limited to emergencies—they’re required whenever the hazard assessment calls for them, even for non-emergency tasks. This ensures protection for the full duration of exposure until controls reduce or eliminate the risk.
