Before using a respirator, several key requirements must be met:
- Medical Clearance: The user must be medically cleared by a physician or licensed healthcare professional to ensure they are physically fit to wear a respirator. This involves completing a confidential medical questionnaire related to health history and the task requiring respirator use.
- Respiratory Protection Program: Employers must have a written respiratory protection program in place that includes respirator selection, medical evaluations, fit testing, proper usage procedures, care, and training.
- Fit Testing: The respirator user must undergo an initial fit test, and then annual fit testing, to ensure the respirator fits properly and forms a tight seal on the face. This test uses the exact respirator model and size used in the job.
- Training: Users need training on why they must use the respirator, its capabilities and limitations, how to inspect and wear it properly, emergency use, maintenance, and how to recognize medical signs that might limit respirator use.
These steps are essential to ensure respirators provide the necessary protection safely and effectively in hazardous environments.
