Fit Test for Groups of 8 or more – 2 Hours

Under the Ontario Health & Safety Act, section 25 (1) (a) states that protective devices are provided. Section 25(1) (d) says that employers must ensure that protective devices provided are used as prescribed. Section 25(2) (a) describes the duty to provide workers with instruction to protect the safety of the worker.

What kind of fit testing do you need?

There are two acceptable methods for Respirator Fit Testing according to the CSA Z94. 4-11. Both a Qualitative and Quantitative method require a trained professional to conduct an in person assessment and training on the selection, care and use of designated respirators. All respirators that rely on a mask-to-face seal need to be checked with either a Qualitative or Quantitative method to determine whether the mask provides an acceptable fit to the wearer. This includes all types of air purifying, air-supplied, positive pressure, powered air-purifying respirators, and SCBA. In Canada, each province maintains its own Occupational Health and Safety guidelines and policies. It is suggested that Respirator Fit Testing to be conducted if any of the following conditions arise;

  • prior to initial use of a tight-fitting respirator.
  • when changes to a user’s physical condition (e.g., significant weight change or changes to facial or dental features) could affect the respirator fit
  • when there is a change in respirator (e.g., make, model, size).
  • when a respirator user experiences continued significant discomfort during use or difficulty in completing a successful user seal check.
  • when there is a change in PPE use that could affect the respirator; and
  • at least every 2 years.

Probuy Offers Qualitative Testing Only

Qualitative Testing: This method of fit testing relies on a subjective sensation (taste, irritation, smell) of the respirator wearer to a particular test agent. This type of testing is appropriate for workers that utilize disposable and air purifying respirators where there is no immediate threat to life. Along with the classroom theory-based training, this method of fit testing provides a flexible, accurate and affordable fit testing experience. Testing takes approximately 15 to 20 minutes per participant. The theory portion provides an influence on workers that emphasizes the importance of correct technique and respirator use.

Qualitative Fit Testing– the following will be discussed during the theory part of the program:

  • Types of respirators
  • Identification of Respirator Cartridges and Gas Mask Canisters
  • Supplied-Air Respirators
  • Self-Contained Breathing Apparatus (SCBA)
  • Requirements for Fit Testing and how they will be done.
  • Issuance of Respirators
  • Self-testing Procedures
  • Negative Pressure Seal Check & Positive Pressure Seal Check
  • Application and use of Respirators including Respirator selection guide.
  • During the fit testing phase, we will cover the proper donning and doffing of the respirator, performing seal checks, care, use and maintenance of the respirator.

Fit Test for Individuals – 30 Minutes

Same as the group accept you will receive the theory portion in written or video form to read or watch yourself prior to the fit test being performed.

Please read the following to ensure you can be fit tested:

Facial hair

Individuals shall present themselves for fit testing free from interference of hair where the respirator seals to the skin of the face or neck. Although the rate of hair growth varies, for many this requires being clean shaven within the previous 24 hours or preferably 12 hours to ensure that hair neither infringes on the sealing surface of the respirator nor interferes with valve or respirator function.

Personal conditions

Individuals shall present themselves for fit testing in the same personal condition they would expect to be in when using the respirator. This includes hair styles (e.g., hair buns) and wearing or not wearing dentures, eyeglasses, or contact lenses.

Personal Effects or Accessories

Individuals shall present themselves for fit testing in such a way that personal accessories such as head coverings, garments, facial jewellery, or other items shall not come between the skin and the sealing surface of the respirator.



Such accessories can impair respirator effectiveness by interfering with valve function, respirator adjustability, and proper secure positioning. Makeup, creams, or lotions can also interfere with effective respirator function.
