Mask Fit Testing

Mask Fit Testing (QUALITATIVE)

The qualitative mask fit testing method is the most widely used and popular method for respirator fit testing. A “fit test” tests the seal between the respirator’s facepiece and the clients face. …

Qualitative fit testing is a pass/fail test method. The mask fit test uses the client’s sense of taste or smell, or their reaction to an irritant in order to detect leakage into the respirator facepiece.  A respirator is a form of protective respiratory equipment designed to protect the wearer from inhaling harmful particulate matter. Common ones are dust, including airborne microorganisms, fumes, and vapors.

 

Any person who is required to wear a tight-fitting facepiece during the course of their normal day to day work duties or any person who is required to wear a tight-fitting facepiece for emergency response activities should be fit tested to ensure an effective seal.

 

Respirator mask fit testing is required in quite a few different fields of work:

  • Medical sector. If there is ever an outbreak of any sort, nurses and doctors should be able to grab a mask and go to work. They are exposed to a wide variety of viruses, sicknesses. Health science students working in a lab or with research may be exposed to disease. A proper mask can help to protect them against airborne disease.
  • Construction  – mask fit tests are required to protect employees from dirt, dust, sand, toxic chemicals etc. Employees could experience serious health issues if they are exposed to contamination and do not have a way to properly protect themselves.
  • Oil and Gas, Fire service Personnel, Lab workers – Some products can be toxic or corrosive. Air Purifying respirators do not protect staff from very toxic IDLH products (Immediately Dangerous to Life and Health) ie- H2S  or  Oxygen Deficient environments

 

 

PURPOSE OF THIS SERVICE:

  • Government required                                               CSA Standard       CSA Z94.4:                
  • Company Policy                                                           Protect the worker from inhaling toxins

CAN FIT TESTING  BE COMBINED WITH OTHER TRAINING SERVICES?

 It can be done as part of  Air Purifying Respirators  (APR)  or Respiratory Protection Equipment (RPE) courses as one component of these seminars.

 

HOW IS A QUALITATIVE FIT TEST PERFORMED?

During fit testing participants will :

  • Learn to put on a respirator and, position it on their face
  • Adjust tension and determine the acceptable fit. Wear it at least 5 minutes to assess comfort of the mask.
  • Positive and Negative seal checks are performed to check the seals of the mask to ensure a proper fit.
  • Do a series of exercises to determine if the mask is fitting comfortably

The client will be tested using one or more of four qualitative fit test methods accepted by CSA Z94.4:

  • Isoamyl acetate, which smells like bananas;
  • Saccharin, which leaves a sweet taste in your mouth;
  • Bitrex, which leaves a bitter taste in your mouth; and
  • Irritant smoke, which can cause coughing
