3M Respirator Fit Testing

Fit testing is required in the US by the Occupational Safety and Health Administration (OSHA) before a user wears a mandatory respirator on the job, and must be assessed at least annually. In addition, fit tests should be performed:
 

• Whenever a different size, style, model or make of respirator is used.
• When any facial changes occur that could affect fit, such as significant weight fluctuation or dental work.

OSHA doesn’t require fit test administrators to be certified, just to know how to conduct a test, recognize invalid tests, and properly clean and maintain equipment.
