Seabrook Station recently sent a Portacount respirator fit test device to the vendor for calibration and it was found to be out of the vendor's standard tolerance of ±15%. 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? Why? 2. What is your minimum overall fit factor? 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? If so, what is the margin? 4. What actions do you take if your Portacount device as-found condition is outside the ±15% vendor standard tolerance? David Perkins SR. RP Analyst NextEra Energy -Seabrook Station Ph:603-773-7079
