Prior to using a respirator, what must the employer provide the handler with?

• A. Medical evaluation
• B. Annual fit testing
• C. Annual respirator training
• D. All of the above

Answer: (A)

Before a handler uses a respirator, the employer must first obtain medical clearance through a medical evaluation. This evaluation checks whether wearing a respirator is safe for the individual, considering any health conditions that could be affected by respirator use and the physical demands of the job. Without this medical clearance, the worker should not wear a respirator, even though fit testing and training are also required in a complete respirator program. Fit testing ensures the respirator seals properly, and training covers proper use and maintenance, but these steps rely on the worker having medical clearance first.
