Quantitative Fit Test (QNFT)

In order for a respirator to provide the intended protection, it must seal tightly to the wearer’s face. AS/NZS1715:2009 states that fit testing is required before a user wears a respirator on the job. Fit tests should be performed annually thereafter.

Booking a quantitative fit test should be part of the scheduled routine when any tight-fitting respirator is being worn. Conducting a facial fit test should be part of the best practice process when:

  • Issuing a new respirator
  • The respirator has been in service for a period of 12 months
  • The wearer has experienced excessive weight gain or loss
  • The wearer has undergone major dental work.

Once the quantitative fit test is completed, the wearer is issued with a pass certificate report. The report of a successful pass will be emailed to both the mask wearer and the wearer’s company.

Jaybro can provide either in-house or on-site respirator fit testing in Sydney. Book an appointment above or call 0436 634 205 for more information.

What will happen on the day?
Prior to the test commencing, you will receive an overview of what is involved in the test & what the test is for, then select the respirator to be tested. You will be shown how to don the mask correctly, then asked to don the mask.

The test, which consists of the following exercises will then begin;

  • Normal Breathing
  • Deep Breathing
  • Head Side to Side
  • Head Up & Down
  • Talking
  • Grimace
  • Bending Over
  • Normal Breathing

Each of these exercises lasts for 60 seconds except for the Grimace which lasts for 15 seconds. The Grimace is only there to break the seal of the mask, and the participant needs to re-adjust the mask to fit properly again.

What is a Fit Test?
Respirators are used to protect the user from inhaling hazardous materials, including vapours, particles and fumes.

The respirator can only perform this function effectively when the seal against the wearer’s face is tight and provides a protective barrier.

A respirator should be fit tested when first issued, and at least once a year thereafter (excluding other factors that could require a mask to be re-tested earlier).

Quantitative Fit Testing (QNTF)
A quantitative test relies on a Portacount machine that is attached to the respirator via a tube to complete the testing.

The quantitative test will not only detect the existence of leakage, but also measures the amount of leakage that is occurring.

Quantitative fit testing is normally the preferred option for full-face respirators and half-mask models, however, any mask can be tested this way.
