How is respiratory protection chosen in a workplace?

• A. Based on a hazard assessment; select respirator type and ensure fit testing and medical clearance.
• B. Based on a worker's preference alone.
• C. Only the weather conditions determine the choice.
• D. Use the most protective respirator regardless of the hazard.

Answer: (A)

Respiratory protection is chosen after a hazard assessment that identifies what contaminants may be present, their concentration, how workers could be exposed, and the tasks involved. Based on that risk, the appropriate respirator type is selected to provide adequate protection while allowing workers to perform their jobs. The process also requires fit testing for tight-fitting respirators to ensure a proper seal and medical clearance to confirm the worker can safely wear a respirator given any health considerations. Weather, personal preference, or always using the most protective option do not determine the choice; protection must align with the actual hazard and the program requirements.
