Respirator Fit Testing - N95, Half-mask, Full-facepiece

COVID-19 UPDATE (August 9, 2021) Respirator Fit Testing continues to be a high-demand service. We are professional fit testers with years of experience. Available fit testing sessions are listed below. Please read through this information prior to emailing questions please.

Fit-testing for COVID-19 related respiratory hazards BEST PRACTICES should:

  • Be completed by a third party and not an employer or management which creates a conflict of interest.
  • Be with the Irritant Smoke Protocol at a minimum. The hood and sweet or bitter solution method is too subjective and depends on the wearer's taste/smell and honest response.
  • Be completed on all respiratory protection provided in the workplace (N95, Half-mask and Full Facepiece Respirators)
  • Be a NIOSH-approved respirator.

Those exposed to respiratory hazards in the workplace or worksite, and required to wear a respirator (N95, a half mask, or a full face-piece) are required to be trained on the selection, use, care and maintenance of this critical piece of personal protective equipment. As well as the training, a qualitative fit test is required to ensure the selected respirator fits the individual and provides the intended protection. Our fit testing training also meets the needs of many college students (ie: those in nursing, PSW and welding programs) whom require record of fit testing for placements.

Employers must ensure that PPE needed for the job is used by workers and maintained in good condition. The PPE must comply with applicable standards. Where required, the employer must ensure that the PPE is used, maintained and stored according to manufacturer’s instructions, applicable standards, and legislated requirements. The workers must be adequately trained on the use of the PPE.

ONTARIO COMPLIANCE ALERT: Respiratory Protection regulations as of January 1, 2020 The Ministry of Labour has finalized changes to the Occupational Health and Safety Act and it's regulations requiring more stringent guidelines on protecting workers from exposures to airborne respiratory hazards. Reviewing your respiratory protection program and fit testing schedule is recommended.


  • CSA Standard Z94.4-18 (-11, -02, -18)
  • O. Reg. 213/91, sections 21, 26 and 93 under the Occupational Health and Safety Act
  • O. Reg. 490/09 (2019) under the Occupational Health and Safety Act - Medical Surveillance for Designated Substances *New for January 2020
  • O. Reg. 449/19 Occupational Exposure Limits (OEL)
  • OHS Act and Regulations that pertain to the use of respirators, multiple sections of the green book. Anyone required to wear a respirator on the job is required to be trained in it's use and have a fit test at least every two years.


  1. Candidates must be clean shaven within 16 hours as per the CSA Standards in order to be fit-tested.
  2. Please remove facial jewelry or other items that come between the skin and respirator.
  3. Fit tests are done on an exact make(s) and model(s) of respirator(s) and not on the category of respirator as a whole. For example, 3M 8210 and not all N95's. Please note that the respirator you are fit-tested on should be in adequate supply.
  4. Candidates are required to provide their own respirator(s) to be fit-tested on or be prepared to purchase one here. If it is an N95/P95/R95 particulate respirator that you're looking to be fit-tested on, I recommend bringing at least two makes/models in case one is not a fit. If you are bringing a half-mask or full facepiece respirator, please bring the P100 filters that match (if not a 3M or Honeywell brand) and ensure it has been inspected to be clean and is in good condition. Respirators are available to be purchased from our retail space for fit testing purposes as needed.


Our Qualitative Respirator Fit Testing meets the CSA Standard Z94.4-18 on fit testing as well as on the selection, use, and care of respirators (Z94.4-02) and includes both a minimum instructional component that varies in length depending on the type of respirator. A qualitative fit test is then completed using accurate irritant smoke test methods. Finally, a short written examination reviews the content for half-mask and full-facepiece respirators (as needed).

Topics covered include the regulatory requirements and responsibilities of the wearer in the use of their PPE, the proper donning and doffing of the respirator, care and maintenance including cleaning and sanitizing, limitations of various respirators, how to complete inspections, compatibility with other PPE, completing seal/pressure checks, identification of respiratory hazards, and information on the proper selection of a filter or cartridge based on the intended use of the respirator.

At First For Safety, we use the most accurate qualitative fit testing methods available.


Qualitative respirator fit tests and training on the PPE is to be completed every 2 years as per the CSA Standards and enforced through our OH&S Act and Regulations. However, if someone changes jobs, losses or gains a significant amount of weight, had an injury to the face, has changed or been requested to change respirators, or if the hazards of the workplace have been re-assessed - a fit test is required. When in doubt, consult the respirator's user manual for the manufacturer's recommendation if under two years.
