TAMARACK SAFETY uses the PortaCount which works by measuring the concentration of microscopic dust particles in the ambient air and then measuring the concentration of those dust particles that leak into the respirator. The ratio of these two concentrations is called the fit factor. The filters stop essentially all the particles so anything that gets into the mask must have come through the face seal. A quantitative fit test is not affected by the person's sense of smell, taste or sensitivity to irritant chemicals. We keep in stock all types of masks including but not limited to:
The individual is provided with a Fit Test card stating the make, model and size of mask (s) as well as the expiry date.
Testing is available at your site or ours, give us a call for a quote!
