Quantitative Face Fit Testing

Also known as a Fit Test, Face Fit Test or Dust Mask Fit Test a Quantitative Fit Test (QNFT) measures the seal between the respirator and the wearer’s face.

There are several compliant QNFT methodologies available to the market. However, ENV elect to use a Controlled Negative Pressure (CNP) method that is administered under the guidance of International Organization for Standard (ISO) standards.

Operated by one of our Occupational Hygiene Consultants, benefits of this method include but are not limited to:

  • Ability to test several brands of masks.
  • Full face or half face testing.
  • Absence of testing chemicals.

Service Inclusions:

Following completion of booking, one of ENV Solutions suitably qualified Occupational Hygiene Consultants will administer the Face Fit Test using one of our QuantiFit2 Respirator Fit Testers.

Following completion of the Fit Test, you will receive an A4 test certificate stating any specific notes that meets relevant standards and guidelines.
