From: [email protected] [mailto:[email protected]] On Behalf Of Nadeau, Marc Sent: Thursday, January 29, 2015 11:27 AM To: '[email protected]' Cc: Perkins, David Subject: Powernet: TSI Portacount 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? Yearly. Why? Because? We've always done it that way? (I "think" that TSI recommends annual calibration. In any event our program procedure specifies annual calibration. THAT requirement was put into the procedure a long long time ago, in a galaxy far far away............ probably "because we calibrate everything else annually"......?) 2. What is your minimum overall fit factor? 1000 for Full face, 100 for half face. 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? Not applicable. 4. What actions do you take if your Portacount device as-found condition is outside the ±15% vendor standard tolerance? We have never seen this. It would be a Case by Case Basis evaluation of the facts. Would write a Corrective Action Document. If the deviation is conservative there would be no further action. For Non Conservative results, we would evaluate the fit testing history to look for trends and determine if retesting would be required. Action taken or not taken would be listed in the Corrective Action Document response (and of course appropriate technical justification for the decision made would need to be included. For example, if a person was recently fit tested, and had a similar fit factor to his or her previous personal history, no action might be justified.) David Perkins SR.
