ANDERSON, JR. \^YY-\ C-8 WORKPLACE EXPOSURE EVALUATION I have analyzed the air monitoring data, supplied by Hike HcCtusky for ten Job assignments at Washington Works, using LOGAH where appropriate. None of the 82 personal samples taken were above the 0.59 moles/billion expo sure limit* (0.01 lag/or}. Three of the ten assignments require at least one more sample to assure that we are meeting our corporate objective of a maximum risk of expo sure above the Exposure Limit [f^L) of 5%. These are: FEP Polykettle Operator (PER5 1BPA) "Teflon" Po1ykett1e Operator (PER5 08PF) Polydispersion Operator (PER5 08PH) The other seven assignments meet this criteria. They are listed below with recommended resampling schedule to assure continued compliance. ASSIGNMENT CODE SAMPLE FREQUENCY 1) Copolymer Pack-Out 2) Warehouse & Materials Handler 3) "Teflon" Autoclave Operator 4) Copolymer Extrusion Operator 5) FEP Wet Finishing Operator 6) Environmental Control Operator 7) C-8 Drier Recovery Operator PERS 18PD PERS 08PD PERS 08PE PERS 18PB PERS 18PC PERS 08PI PERS 08PM One control/year Ho further sampling required One control/year No further sampling required Ho further sampling required One control/year Ho further sampling required The test data are attached. *The p1ant.,is apparently operating with a limit of 0.56 ppb versus the AEL of 0.01 mg/m . According to my calculation using 414 as the molecular weight for C-8, the limit should be 0.59. Tony PJaytis by copy of this letter should check to confirm. ^npoffi ^SSaEssBsaafei'A-- EID078445
