Respiratory Fit Testing
To ensure your protection, a respirator must fit properly and form a good seal on your face when in use. Fit testing ensures the safety of a worker required to use a tight fitting facepiece to do their job.

  • Qualitative and quantitative fit tests for respiratory protection are available at our location or at your job site
  • For optimal protection, a respirator must fit properly; this is verified through a proper fit test
  • Upon successful test completion, fit test record cards are provided listing respirator model and worker identification
  • All testing is done in compliance with CAN/CSA-Z94.4-18

Fit Testing FAQs

When is a respirator fit test needed?

A Fit Test is required before a worker / employee undertakes a tasks that requires the use of a tight-fitting respirator, a tight-fitting respirator can be any of the following

  • disposable P2/N95
  • half-face reusable
  • full-face reusable
  • tight-fitting Powered Air Purifying Respirators (PAPR).

Every piece of Respiratory Protective Equipment (RPE) must be appropriately fitted and sized for the individual wearer. When control of exposure to occupational hazards requires the us of respiratory protection, managements needs to ensure a RPP is implemented as part of a risk control strategy. This includes conducting fit testing for staff who are required to use RPE

Why is fit testing required ?

Conducting a fit test is crucial for several reasons:

Ensure Proper Fit: Every face is unique, and respirators are not one-size-fits-all. A fit test helps ensure that the respirator fits securely on the wearer’s face, reducing the risk of harmful exposure.

Protection Against Respiratory Hazards: A proper fit ensures that the respirator provides the desired protection against airborne particles and hazardous materials in the work environment.

Compliance with Regulations: Many health and safety regulators, like WorkSafe Victoria, require fit testing to be part of a Respiratory Protection Program (RPP). Failure to conduct fit tests can result in fines and penalties.

Employee Comfort and Confidence: A properly fitting respirator is more comfortable for the wearer. It also boosts employee confidence in their safety equipment, leading to increased usage and compliance.

Risk Control Strategy: Fit testing is an essential part of any risk control strategy, ensuring that workers are properly protected when exposure to respiratory hazards can’t be entirely eliminated.

In essence, fit testing is a critical step in ensuring worker safety, regulatory compliance, and effective risk management in environments with respiratory hazard.

Is respirator fit testing required ?

In short yes, if staff are required to wear a โ€œtight fitting respiratorโ€ then fit testing of that respirator is required and is a critical part of occupational safety. Regulatory bodies such as WorkSafe Victoria mandate that before an employee first uses a tight-fitting respirator, they must undergo a fit test. This test is essential to verify the effective seal between the respirator and the wearer’s face, ensuring optimal protection against airborne contaminants in the work environment

What is Fit Testing ?

Respirator fit testing, often referred to as facial or mask fit testing, is a procedure conducted to confirm whether an effective seal is formed on the wearer by their selected Respiratory Protective Device (RPD).

The essence of a secure seal on tight-fitting respirators cannot be overstated. Without it, the wearer remains vulnerable to their surrounding environment, potentially leading to harmful health implications in certain situations.

How Is a Respirator Fit Test Conducted?

Two primary methods are employed for respirator fit testing: the Qualitative Fit Test (QLFT) and the Quantitative Fit Test (QNFT).

The QLFT involves using a challenge agent within a controlled hood. The wearer’s ability to taste or smell the test agent is assessed, determining whether an effective seal is formed on disposable and half-face reusable respirators. This method offers a pass/fail result based on the wearer’s sensory response.

On the other hand, the QNFT employs a machine for conducting the fit test. This machine can either be a Controlled Negative Pressure (CNP) machine, which uses air pressure to ascertain if a proper seal is achieved on half-face and full-face reusable respirators, or a Condensation Nuclei Counter (CNC), which compares particle counts inside and outside the mask to verify the seal on all P1, P2 disposable, half face, and full-face respirators.

At N95 Fit Test, our preferred method is the QNFT, utilising the state-of-the-art model 8048 Portacount (CNC) Machine we are able to fit test all tight fighting respiratory protection devices
