Respirator Mask Fit-Testing: N95 MASKS

The Canadian Standards Association (Z94.9.1.6) and the Ontario’s Occupational Health & Safety Act (OSHA) state that every worker using a respirator to perform their job must be fit-tested, and employers are required to protect them from potentially hazardous airborne particles including biological or chemical agents. If you’re required to wear an N95 filtering facepiece mask as part of your job, you MUST be fit-tested with the proper make, model and size provided by your employer before it’s first use.

Spartan Response provides Qualitative Respirator Fit-Testing (QLFT), an OSHA approved procedure that relies on the sensory (taste, irritation, smell) response to a particular test agent in order to detect leakage into the respirator. Spartan Response uses two different agents: Saccharin (sweet) and BitrixTM (bitter).

Our QNFT service can be performed in under 20 minutes and uses several exercises to verify the N95 mask is the correct “mask-to-face seal,” and ensures the worker understands how to properly operate their mask. The “Fit-Test Certification” wallet card confirms the worker has successfully passed the fit-testing procedures, and is safe to use their mask on the job.

N95 MASKS WE FIT-TEST: We only fit-test N95 filtering face masks approved by the National Institute for Occupational Safety and Health. (NIOSH). It is important to note that N95 masks are designed for one-time use. Only new (never worn) N95 masks will be fit-tested.

The most common types are 3M N95: 8110S, 8210, and 9210.

PURCHASING A MASK WITH YOUR FIT-TEST: Employers are responsible to provide their workers with the proper N95 respirator masks to be fit-tested. In some cases, they allow employees to purchase the mask required to perform their job for reimbursement. Spartan Response carries a limited inventory of N95 masks for purchase, however due to COVID-19, there is a shortage. If you’re looking to purchase a mask with your fit-test, you must call ahead to confirm availability.
