In order to assess worker exposure to 1,3-butadiene (106990) at a polymer production facility, an in depth industrial hygiene survey was conducted at Firestone Synthetic Rubber and Latex Company (SIC- 2822), Lake Charles, Louisiana. This facility incorporated a number of controls designed to prevent the release of chemical intermediates and products into the air. Personal protective equipment included rubber, cotton, or vinyl gloves depending on the job performed. Respirators were required for field lab samplers and maintenance personnel performing specific tasks. Half face organic vapor respirators were used. Individual short term exposures greater than 10 parts per million (ppm) were measured for a field laboratory technician and a pipefitter during the survey. High full shift exposures were measured during the survey for B-operators in the tank farm and purification unit. Current exposure control programs at the facility maintained arithmetic mean 8 hour worker exposures to less than 10ppm of 1,3-butadiene. The authors recommend that consideration be given to converting to a closed loop sampling system for obtaining quality control samples. The use of dual mechanical (tandem) seals was also recommended for pumps. Respirators with organic vapor cartridges should be used by pipefitters during maintenance activities. A program to convert from slip tube gauges to magnetic gauges should be considered for monitoring 1,3-butadiene on barges and rail tank cars.
