Face Fit Testing

K2A is an independent Fit 2 Fit accredited company specialising in face fit testing helping companies comply with the requirements of legislation and industry regulations. Face fit testing is a method for checking that a tight fitting face piece matches the person’s facial features and seals adequately to the wearer’s face. If masks are worn in the workplace then you will be required to provide evidence of a fit test for each mask worn. Face fit testing is required under the COSHH, CLAW and CAW Regulations for all tight-fitting face-pieces.

Quantitative Face Fit Testing

Quantitative testing determines that a tight fitting face piece; provides an adequate seal to the wearer’s face by measuring microscopic particles that exist in ambient air, it measures the particles outside the face piece and then measures the concentration of those particles that leak into the respirator whilst the wearer carries out a number of specific exercises. For this test we use the TSI Portacount Plus Respirator Fit Tester which is a particle counting device.

The types of RPE that can be fit tested with this method include:

  • P1, P2 and P3 disposable masks
  • Full face mask respirators
  • Power assisted respirators
  • Half mask respirators
  • Breathing Apparatus, full and half masks

Power assisted respirator or breathing apparatus face pieces are fitted with an adapter to allow them to be converted and tested as a negative pressure respirator for test purposes.

The benefits of this test type are that all types of RPE can be tested with this method, the machine counts the particles and calculate a fit factor and the tester does not have to rely on the person’s word that the mask fits properly. After the completed test the machine produces a pass/fail computer generated report.

Qualitative Face Fit Testing

Qualitative Fit Testing is a pass/fail test that is dependent on a subjective response from the respirator wearer.

The person is fit tested while wearing a respirator inside a hood, a sweet or bitter spray is sprayed inside the hood whilst the person carries out some exercises, if the wearer detects the smell of the spray during the test than the fit test is deemed as unsatisfactory. Types of qualitative fit testing agents are saccharin, bitrex, isoamyl acetate (banana oil).

Qualitative fit testing is only for disposable masks and half mask respirators.
