B. Personnel &ir Monitoring for C-8
Hg McCluakv/Wft Ott
C-8 in air personnel monitoring waa last conducted in 1988 when
Polymers and Copolyniers areas were both using powdered C-8 exclusively, Liquid C-8 replaced powdered C-8 in August, 1989. Personnel monitoring was restarted in January, 1991 to compare the effecta of liquid C-8. Monitoring was completed in Polymers in April and was started in Copolymers in June.
A contract employee was hired to observe the job assignment being monitored. For Polymero, seven joba were covered, including the Warehouse 6 Materials Handler (created with use of liquid C-8) and the c-8 Recovery
job.
the AEX. ia O.S6 MPB (moles per billion). The limitation of the teat
is 0.03 MPB. Resulta are tabulated below;

NOTE: The maximum level measured was 0.215. All of the results for
the Warehouse & Materials Handler, C-8 Recovery, and Dispersion Packout
were below the 0,03 MP8 level.
The above results compare favorably to the use of powdered c-8. The job assignment with the most noticeable decrease waa the Autoclave
operator, followed by the Granular polykettle. These are the two assignments that would expect to benefit the moat from liquid C-8.

TITLE; C-8 IN AIR PERSONNEL SAMPLING FOR COPOLYMERS
ABSTRACT; PERSONNEL 8AMPLING FOR COPOLYMERS MAS COMPLETED
MAS TO EVALUATE TODAY'S USE OF LIQUID C-8 VERSUS OBSOLETE RESULTS MERE MELL BELOM THE AEL. (MCCLUSKY, OTT. BALL)
IN JULY. THE PURPOSE
POWDER C-8. ALL
DISCUSSION; LIQUID C-8 USE REPLACED POMDER C-8 IN SEPTEMBER 1989. THE PURPOSE FOR THE CHANGE MAS TO ELIMINATE EMPLOYEE EXPOSURE TO C-8 DUST IN PROCESS MAKEUP. THE COPOLYMERS BTO MAS MEASURED IN JULY TO DETERMINE THE EXTENT OF C-8 IN AIR EXPOSURE TO PERSONNEL.
SOME THIRTY-TMO SAMPLES MERE TAKEN IN FIVE FEP ASSIGNMENTS: I)POLYKETTLE, 2)EXTRUDER, 3)OVEN, 4)MET FINISHING, AND 5)PACKOUT. THE RESULTS ARE SUMMARIZED

THESE RESULTS ARE MELL BELOM THE AEL. SIXTY PERCENT OF THE RESULTS AR BELOM THE MINIMUM DETECTABLE LEVEL. THESE RESULTS ARE ALSO AN IMPROVEMENT OVER
THE LAST SAMPLIN8 CONDUCTED MITH POMDER C-8, IN 1988. THE TEFLONO POLYMERS' BTO MAS SAMPLED FOR C-8 IN AIR EXPOSURE MITH RESULTS
REPORTED IN MY IIQ 91 QUARTERLY. MILLIAM ANDERSON, MILMIN6TON S.H.E., HAS ALL
POLYMERS AND COPOLYMERS RESULTS. HE HAS RESPONSIBILITY FOR DETERMINING IF ANY ADDITIONAL SAMPLING IS REQUIRED.
