When is medical clearance required for respirator use?

• A. Only for full-face respirators
• B. It is required when respirator use could affect health or as dictated by the program
• C. Never required
• D. Only for half-face respirators

Answer: (B)

Medical clearance is required when wearing a respirator could affect health or as dictated by the program. Wearing a respirator adds breathing resistance, heat, and communication challenges, and for some workers these demands may pose health risks. A medical evaluation by a licensed healthcare professional looks at the worker’s health history, current conditions, and physical tolerance to determine if it is safe to use a respirator for the expected tasks and duration. The respiratory protection program may require clearance for all users or only in certain situations or with certain respirators, so the requirement is driven by health risk and program policy, not by a specific respirator type alone. The goal is to identify any restrictions or accommodations before fit testing and actual use.
