Use caution when opening attachments, clicking links or responding to requests for information. 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? Annually Why? Vendor recommendation 2. What is your minimum overall fit factor? As required by regulations for the different types of respirators. 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? N/A 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 either do nothing, or conduct new fit tests as appropriate. David Perkins SR. RP Analyst NextEra Energy -Seabrook Station Ph:603-773-7079
