Abstract
A walkthrough industrial hygiene survey of the Philtex facility of Phillips Chemical Company (SIC-2869), Borger, Texas, was performed to determine its suitability for inclusion in a 1,3-butadiene (106990) exposure survey. Of 212 employees, 33 were potentially exposed to 1,3-butadiene. Facility history, manufacturing process, quality control, past exposures, and engineering controls were examined. Medical, safety and industrial hygiene programs were studied. Bulk polymer samples were analyzed for free monomer emanation at ambient, highest polymer process, and highest estimated end use temperatures. Industrial hygiene monitoring results showed the mean time weighted average (TWA) 1,3-butadiene exposure was 1.7 parts per million (ppm); 75 percent of TWA exposures were less than single mechanical seals although reactor agitators had dual mechanical seals. 1,3-Butadiene exposures occurred primarily during maintenance and quality control sampling. Materials produced from 1,3-butadiene were tested to determine the levels of the compound released. At 30 degrees-C, trace amounts of 1,3-butadiene were detected in a sample of Butarez and 140 nanograms per milligram was found in Sulfolene, but no 1,3-butadiene was detected in Sulfolane or R-11 at any analytical temperature. The authors conclude that this facility is a candidate for an indepth industrial hygiene survey. Installation of a closed loop quality control sample collection system and installation of double mechanical seals are recommended.
