Legendre- Ponca City August 1982 September 10, 1982 ALL SAMPLE RESULTS: Chemical VCM Lead Antimony Total Particulates PEL No. % 82 86,3 4 80 0 3 100 > PEL 0VEREXP0SURES No. % 13 13.7 1 20 0 00 OVEREXPOSURES: Job Class Color Weigh Compounder General Mechanic Exposure 340* Micrograms 1ea d/M^ 1.6 ppm, VCM General Mechanic Electrician 9.9* ppm, VCM r 77.6 ppm, VCM Source Employee helped clean out the compound vacuum system hopper. Employee dick-ileak repairs during a VCM leak survey conducted by Process Engineering. He also helped change out the 745 VCM charge valve. Employee helped open the north VCM receiver in the old vinyl unit in preparation for main tenance. Employee exposed while doing greasing work near the knockout tanks on the 2nd floor of the new unit recovery building. VCM was being evolved from the sewer at that point. The source of the VCM has not yet been de termined. VAB.0001073513 Overexposures (Continued) Job Class Maintenance Helper Exposure 11.0 ppm, VCM Chief Operator Chief Operator 3.9* ppm, VCM 1.1 ppm, VCM Chief Operator 2.5 ppm, VCM Reactor Operator Reactor Operator Reactor Operator Reactor Operator Reactor Operator 1.3 ppm, VCM 19.7* ppm, VCM 1.9 ppm, VCM 3.5* ppm, VCM 5.7* ppm, VCM Source Employee headed up the north recovery condenser in the old unit and changed a safety disc on 903 compressor (new vinyl unit). Employee changed VCM filter pack filters. Employee worked near VCM leaks occurring in several lines, flanges, etc. during the start up of the old vinyl unit on 8/10/82. Employee worked in new vinyl unit the bulk of his shift. The cause of his exposure is not certain. He assisted in manually operating the new unit inlet valve to the re covery compressors and also worked near the dump system during a long dump from 743 ("chunk" lodged in manifold, requiring j'lush out). Same as Chief Operator having 2.5 ppm, VCM, except this employee also took slurry samples at the Sweco. Employee changed VCM filter pack filters. Same as Chief Operator having 1.1 ppm, VCM Employee drained a knockout tank in the new unit. Employee changed out seal water filters in the old unit.

A Source Same as Chief Operator having 2.5 ppm, VCM, except he did not assist in the manual operation of the inlet valve to the recovery compressors. He also switched lines at the resin silos.
