PETRIN To: CC: Re: From: Date: Ms. Darlene Creel Mr. Marty Morrison Petrin Corporation Sample # 13914 Daniel Cortez; Petrin Corporation 11/01/93 CORPORATION Consistent quality in Industrial Insulation for two decades. We regret that an error was made concerning the location of sample number 13914 dated 02/24/92. On this date, employee # 435-06-2532 was working in Power II not in Power I as was stated in the attached Asbestos Monitoring Data Results and Louisiana Division Industrial Hygiene Sample Record. Please note correction and file with attached erroneous documents. If you have any further questions, please contact me at ext. 6300. Thank you.

TWA LIMIT - 0.20 FIB/CC 30-MINUTE LIMIT = 1.0 FIB/CC LIMIT OF DETECTION = 7 FIB/MM2 LIMIT OF QUANTITATION = 100 FIB/MM2 DATE SAMPLE* PERSONNEL DESCRIPTION 2/24/92 13914 '435-06-2532 Insulator: Putting transtte boards on coder tower DtlBfMIN) 30 VOL(L) 72 ' The proper protective clothing was worn during the Job. North 7700 Respirator with HEPA filters were worn during the Job. ** LOD ***LOQ E1B/CC E1B/CC 0.01 <0.53 Note: The Limit of Quantitation has been defined as 100 Fibers/MM2 using the minimum fiber loading criteria specified. In the NIOSH analytical method 7400, hie stated range of the method Is 100 to 1300 Fibers/MM2 filter area. Although samples below this range can be analyzed, the method has not been validated below 100 Flbers/MM2. However, the NIOSH method 7400 also establishes the estimated Limit erf Detection as 7 Flbers/MM2 (Reference OSHA Std. 1910.1001, Appendix B). Based on this Information, we will establish 100 Flbers/MM2 filter area as our Limit of Quantitation aid 7 Fibers/MM2 filter area as our Limit of Detection (which Is more representative of the actual fibers present) for asbestos monitoring. We wll report both Unfit of Quantitation and Limit of Detection. If only Unfit of Quantitation were expressed, the minimum reportabie result would calculate to be 0.04 Fibers per cc for an 8-hr. Time weighted average sample at a flow rate of 2 liters per minute and 0.6 fibers per cc for a 30 minute time weighted average short term sample at allow rate of 2 liters per minute. ...... ^ (Ac ~T<r^+~ CO A n 4640 C-ONFTDFNTTAl --*"* t LOUISIANA DIVISION INDUSTRIAL HYGIENE SAMPLE RECORD 2W c/t**'*/ /pQU-*r -LPLANT/DEPT.
