So, we are benchmarking to understand how others maintain Portacount devices and are asking if you would please answer 4-benchmark questions? BENCHMARK QUESTIONS If you use TSI Portacount devices to perform respirator fit testing; 1. How frequently do you calibrate your Portacount device? Annually Why? Vendor recommendation 2. What is your minimum overall fit factor? As required by regulations for the different types of respirators. >1000 3. Do you add margin to your minimum overall fit factor in the event that the Portacount as-found condition is outside the vendor tolerance? No If so, what is the margin? We would take the unit out of service if found outside the vendor tolerance. Our units are checked prior to use, so we would see if it is out of tolerance and place it out of service. 4. What actions do you take if your Portacount device as-found condition is outside the ±15% vendor standard tolerance? We haven't observed this. If we had this situation we would evaluate history of daily check performances and the potential impact of the difference on fit tests performed in accordance with our corrective action program. Depending on the outcome of this evaluation we would restrict individuals qualifications and conduct new fit tests as appropriate. David Perkins SR.
