Respirator Medical Evaluation

What is a Respirator Medical Evaluation?

A worker must be medically cleared by a Physician or Other Licensed Health Care Professional (PLHCP) before being fit to wear a respirator. Medical clearance plays a critical role in the process as respirators can make breathing difficult. OSHA has designed a medical questionnaire to assist PLHCPs in determining who is medically cleared to wear a respirator and work safely. 

The respiratory protection standard requires an initial medical evaluation to determine the employee’s ability to use a respirator before an employee is fitted or required to use the respirator in the workplace. 

Frequently Asked Questions

It is recommended that a worker have a medical evaluation before fit testing, especially if this is the first time being evaluated in the clinic and there are no previous records. This evaluation includes testing of the baseline pulmonary function (PFT).  The questionnaire qualifies as a type of evaluation; however, sometimes further evaluation is required before medical clearance for respirator fit testing.  

Not necessarily. Physician or Other Licensed Health Care Professional (PLHCP) would recommend accommodations for the employee to safely perform the job function; however, it is up to the employer to determine whether they can accommodate the recommendations.
