Respirator Medical Clearance vs Fit Test


MEDICAL CLEARANCE
A medical clearance confirms that you are medically able to safely wear a respirator. The Occupational Safety and Health Administration (OSHA) requires this approval before you may use a respirator at work (29 CFR 1910.134).
HOW IT WORKS
You will complete an online medical questionnaire about your health.
-
A doctor or licensed healthcare provider will review the questionnaire.
-
The reviewing provider may require you to undergo a medical examination.
-
If approved, you will receive a written clearance from HealthForce.
FUTURE REQUIREMENTS
You need a new medical clearance if:
-
your health changes, or
-
according to the practicing licensed healthcare provider.

FIT TEST
A fit test makes sure your respirator forms a tight seal on your face. The Occupational Safety and Health Administration (OSHA) requires this (29 CFR 1910.134(f)). A poor fit can let in harmful air.
TWO TYPES OF FIT TESTS
Qualitative – Uses a strong smell, taste, or irritation to check for leaks.
Quantitative – Uses a machine to measure how well the respirator seals.
HOW IT WORKS
-
You put on the respirator.
-
You perform movements (like turning your head or talking).
-
The test checks if air leaks in.
FUTURE REQUIREMENTS
-
Fit tests must be performed once a year or if you change masks or face shape (like weight loss or surgery).
REGULATORY COMPLIANCE
Both the medical clearance and fit test are required by Occupational Safety and Health Administration (OSHA) to keep workers safe. Need more information? Learn about OSHA respirator standards on their website.
