The 3M Qualitative Fit Test Apparatus offers a simple way to meet the Occupational Safety and Health Administration’s (OSHA) qualitative fit testing requirements. It can be used to assess the face-to-respirator seal of any particulate respirator or gas/vapor respirator with a particulate prefilter.
Fit testing must be performed before a respirator is first issued to a healthcare worker and is required annually thereafter. (Note: a separate user seal check must be performed each time the respirator is worn.)
Fit testing is accomplished by spraying a test agent into the hood environment with the respirator in place. If the wearer does not detect the taste of the test agent, an acceptable fit has been demonstrated.
