A walk through survey was conducted at the Copolymer Rubber and Chemical Corporation (SIC-2822), Baton Rouge, Louisiana. The facility produces 465 million pounds of styrene butadiene rubber (SBR) and 15 million pounds of nitrile butadiene rubber (NBR) annually, requiring 120 million pounds of 1,3-butadiene (106990). Of 470 employees, 143 were directly involved in reaction, recovery, and finishing operations, and were potentially exposed to 1,3- butadiene 8 hours per day. An additional 294 employees were potentially exposed intermittently. Company monitoring data show a weighted mean of the 8 hour time weighted average exposures of 2.4 parts per million (ppm) for these job categories. Engineering controls included dual mechanical seals on newer pumps, single mechanical seals on older pumps, dual mechanical seals on reactor agitators, rail car vapor vents, and locally exhausted lab hoods. Bulk samples of SBR and NBR were 0.2 (NBR) and 0.8ppm (SBR) of 1,3- butadiene by weight. The authors conclude that the company should be included as a candidate for an indepth industrial hygiene survey to develop an extent of exposure profile for all job descriptions associated with the production and distribution of 1,3-butadiene based products. The authors recommend that the company pursue its plan for installing a closed loop sampling system throughout the facility.
