Respirator Fit Testing

The Occupational Safety and Health Administration (OSHA) requires employees who work in a hazardous environment (environments with harmful dusts, fumes, gases, etc.) to wear respirators. These respirators protect the wearer against toxic atmospheres, allowing them to breathe with reduced exposure to respirable toxins. However for yours or your employees’ respirators to be most effective, a Respirator Fit Test is necessary to ensure proper fit and function while in use. 

A Fit Test tests the seal between the respirator’s face piece and your face. This ensures the effectiveness of the respirator. Fit testing is not only required by OSHA, but keeps your employees safe from contaminants produced in their work environment. The respirators only work if the intended protection is verified.  

OccuMed can conduct fit tests in one of two ways:

Quantitative Fit Test

Qualitative Fit Test

Using state-of-the-art machinery, PortaCount, OccuMed can perform Quantitative Fit Testing to ensure your respirator fits properly and is effective and takes only fifteen to twenty minutes to complete.

Based on the user’s sense of taste and smell, OccuMed’s Qualitative Fit Test uses a spray or smoke solution within your covering to test the effectiveness of your respirator’s seal while conducting a variety of exercises. 

No matter the type of test you choose to take, when you are scheduled for your fit test, there are some guidelines to keep in mind and some rules you or your employees will need to follow:

Medical Evaluation Questionnaire

Before the test can be conducted, a completed MEQ is required. This can be provided by an employer, or, if the individual taking the test does not have one prepared, can be provided by OccuMed


Bring the exact same make, model, style, and size of respirator you will be using on the job to your test

Clean Shaven Face

Facial hair that lies along the sealing area of a respirator, will interfere with respirators that rely on a tight face piece seal to achieve maximum protection

Individual/Small Group Testing
