Frequently Asked Questions

• Verification of Training:  After the individual has received respirator training, a fit test checks that the person has learned how to properly don and wear a respirator without assistance.  
• Sizing: It is important to make sure that the individual is issued a properly sized respirator that is capable of providing protection when worn properly.  

All tight-fitting respirators require a seal in order to work. If an employer requires a worker to wear the following types of respirators, a fit test is needed:

• Filtering facepieces such as N95 or KN95 masks
• Half-face respirators
• Self-Contained Breathing Apparatus (SCBA’s)

• We currently fit test the following respirators:
• MSA G1
• 3M Scott
• Draeger P & RA Models
• Half Face Respirator
• N95

• Avoid eating, drinking, or smoking for at least 45 minutes before the test, as this can affect the results. 
• Make sure your face is clean-shaven, as facial hair can interfere with the mask's seal. 
• Bringing the respirator you plan to use at work is also necessary.

• A qualitative fit test relies on your senses to determine if there is a gap in the seal of your respirator. 
• A quantitative fit test uses an instrument to numerically measure the effectiveness of your respirator.
• Newfoundland Face Fit use the most current TSI Portacount  quantitative equipment.
