Respirator fit testing performed to determine if an employee can maintain an acceptable respiratory fit and seal. Fit testing must be done prior to use, whenever a different respirator is worn, and at least annually thereafter. Fit testing will be administered using an OSHA-accepted qualitative fit test or quantitative fit test protocol. The employee must be tested with the same make, model, style, and size of respirator that will be used.

 

iota utilise the PortaCount 8083 particle counter for quantitative fit testing. The PortaCount system can be used in conjunction with any type of respirator with a tight-fitting face piece. We hold a wide range of varying adapters to fit most manufacturers face pieces allows employees to be tested in their own respirator. 

Using a portacount computerized testing machine,this Fit Testing determines the adequacy of the face-to-face piece fit or seal of a given type, make, model, and size of a tight fitting face piece respirator by measuring the particulate contaminate concentration outside the face piece (ambient air), to the concentration inside the face piece. This quantitative measurement is called the Fit Factor and reflects seal adequacy.
