Respirator fit testing is important to make sure your mask can protect you by measuring a proper fit.
Wearers cannot be protected if there are gaps, so it is necessary to test the fit before entering into contaminated air. Multiple forms of the test exist.
A correct fit is achieved by tightly pressing the mask flush against the face (without gaps) to ensure an efficient seal on the mask perimeter.
When should I conduct a fit test?
Fit testing is required by Australian New Zealand Standard AS/NZS1715 before a user wears a respirator on the job. The respirator should be assessed at least annually.
Fit tests should be performed whenever a different size, style, model or make of respirator is used. Facial changes that could affect fit, such as significant weight fluctuation also require updated fit testing.
Qualitative or Quantitative fit test?
Equipment can determine the concentrations of a control substance inside and outside the mask or to determine the flow rate of air flowing under the mask. Quantitative methods are more accurate and reliable than qualitative methods.
OCTIEF offer quantitative fit testing from our Laboratory offices, or if required we can come to you onsite. Call 1800 628 433 for a booking
