Respirator Fit Testing

Environmental Health & Safety offers fit testing for any individual affiliated with the George Washington University (students, faculty, staff, etc.) whose role requires them to wear a NIOSH-approved respirator or facepiece.  


To ensure any individual required to wear a respirator (such as an N95 mask) is wearing it appropriately, securely, and safely.  This includes affirming a proper seal between the respirator's facepiece and the wearer's face so as to prevent contaminated air or hazardous substances from penetrating the respirator and being inhaled.


1.0 hours for every 10 participants.


To register for fit testing, please fill out our Respirator Fit Testing Web Form.

Frequently Asked Questions

Yes.  Any department mandatingthat students, faculty, staff, etc. must provide those individuals with the appropriate respirator, per OSHA regulations.  Reach out to your lab manager, instructor, Principal Investigator, or Chemical Hygiene Officer (CHO) for assistance.

Your mask must be a NIOSH (National Institute for Occupational Safety & Health) approved respirator.  The N95 nomenclature (a popular respirator distributed among GW labs) indicates the respirator filters at least 95% of airborn particles.

Check to see if your mask:

  1. Displays "NIOSH" or the NIOSH logo.  


If you still have questions as to your mask's legitimacy, reach out to your Chemical Hygiene Officer (CHO) or email our Environmental Health & Safety team at: [email protected]

No.  Fit testing is a qualitative and quantitative process involving multiple test methods.  As such, the scheduled time frame is necessary to complete everything required to ensure the respirator fits appropriately, securely, and safely.  

Facial hair worn below the chin can creat an improper seal.  An improper seal allows for potentially contaminated air or hazardous substances to penetrate the mask and be inhaled.

Individuals requesting an exemption to the clean-shaven guidelines must submit a waiver and complete additional training in a Powered Air Purifying Respirator (PAPR).  Please reach out to your lab manager, instructor, Principal Investigator, or Chemical Hygiene Officer (CHO) for additional information.
