Respirator Medical Evaluation Toolbox Talk

Wearing a respirator places additional demands on the heart and lungs. For some workers, these demands may increase the risk of medical complications during work. A medical evaluation helps determine whether a worker is medically able to wear the required respirator safely before participating in activities that require respiratory protection.

This toolbox talk reviews the purpose of respirator medical evaluations, worker responsibilities, and the importance of reporting any changes in health that could affect respirator use.

Why This Matters

• Medical evaluations help ensure workers can safely wear required respirators.
• Some medical conditions may affect a worker's ability to use respiratory protection safely.
• Medical clearance is an important part of an effective respiratory protection program.
• Early identification of medical concerns helps prevent emergencies during work.
• Workers should report changes in their health that may affect respirator use.

Common Hazards

• Using a respirator without the required medical evaluation.
• Breathing difficulty while wearing a respirator.
• Medical conditions affecting the ability to safely wear respiratory protection.
• Ignoring symptoms such as dizziness, chest pain, or shortness of breath.
• Changes in health that have not been reported or evaluated.
• Heat stress increasing the physical demands of respirator use.
• Using the wrong type of respirator for the task.
• Failing to follow the company's respiratory protection program.
