AR226-2004 W* *1 * February 8, 1988 /ZJ fO! ALL TEFLON* PERSONNEL FROM! BILL OTT/JIM POST C-8 IN AIR MONITORING This letter is to communicate to all TEFLON* employees that a change in our C-8 monitoring program vill occur in 1988. Personal and area sampling for C-8 has continued at very high levels since our program began in 1980. The results of these samples indicate that the sample schedule could be reduced and still adequately monitor employee exposure to C-8. In order to accurately define which jobs require continued sampling and which jobs do not, we will begin a characterization of all PERS job classifications which have C-8 exposure. Characterization means that each FERS job to be studied will undergo 6-10 carefully Careful monitoring is where one person wears a personal sample monitor and a second person carefully notes where the sampled person ^ sampled. In this way, we can document with high accuracy the process exposure that the sampled person received. Examination of these results will permit us to establish the new sample schedule. During the characterization process, no other routine C-8 in air monitoring samples will be taken. The production areas will continue to use area samples to monitor equipment for process leaks. * Du Pont's registered trademark for its fluorocarbon resins 007710 . AJP002311 EID079681
