General Information

Respirator Fitness Testing

Whether you use a mask for protection from Asbestos, Viruses such as Covid-19, lead, dust or any work requiring a mask or respirator, The Australian Standard AS/NZS-1715:2009 states that the proper fitting of respiratory protective equipment requires the use of a fit test to determine an adequate match between the facepiece of the RPE and face of the wearer, and recommends annual fit testing of respirators.

EnviroX Consulting provides in house or on site respirator fit testing. We use the Quantitative method using a TSI portacount respirator fit tester which eliminates the guesswork associated with qualitative fit test methods. Passing a Quantitative fit test proves that the respirator is sized correctly and the person is competent in donning the respirator.

Upon passing the fit test the wearer is issued with a fit test report and printed fit test card which states name, ID number, date of test, next test due, mask tested on and the overall fit factor. A fit factor of 100 is required for half face masks, and a fit factor of 500 is required for full face masks.

It is recommended you bring your own mask for fitting if you already use one so that we can ensure it fits you adequately. Out consultants can provide advice and aid to help your mask seal properly on your face, while measuring a live fit factor to ensure your fit test passes. EnviroX Consulting can provide various styles of mask for you to try to make sure you leave your fitting with a suitable fitting mask that achieves a suitable fit factor and will keep you safe.

We ask that any facial hair is shaved prior to your mask fit test, as facial hair can inhibit the seal on the mask, interfering with the fit factor. The attendee must not eat, smoke, drink coffee or chew gum for at least 1 hour prior to the fit test to prevent interference with test measurements.


Quantitative fit test (OSHA)

A quantitative fit test can be use to test any tight-fitting respirator including disposable, half face or full face masks to ensure a proper seal that protects the wearer. This type of fit test is more accurate than a qualitative fit test , known as the gold standard for respirators involved in hazardous work; and uses a Portacount to measure leakage around the face seal by comparing particulates inside the mask compares to outside the mask, resulting in a number called the “fit factor”.

This test involves the user performing four short exercises while wearing the respirator as the readings are taken, breathing as normal:

  • Bending down and back up
  • Running on the spot (reading poem)
  • Turning the head side to side
  • Tilting the head up and down

This ensures readings are taken in a variety of situations that may affect the seal of an inadequately fitting mask to give an accurate fit factor of the mask during real use, ensuring the effectiveness of a mask that meets the required fit factor for its type.

Prior to any renovation or demolition for a building built prior to 2003 an asbestos inspection/asbestos material survey / hazardous material survey should/must be conducted
