In an effort to evaluate worker exposure to 1,3-butadiene (106990) at a monomer production facility and to determine the status and nature of existing engineering controls and industrial hygiene programs, an in depth survey was conducted at Texaco Chemical Company's (SIC-2869) location in Port Neches, Texas. In March of 1980 the facility began recovering 1,3-butadiene from crude ethylene unit byproduct feedstreams purchased from outside producers. Employee 8 hour time weighted average exposures varied greatly across different job categories. Laboratory technicians performing sample cylinder cleaning had the highest mean exposure, 125 parts per million (ppm) of any job category. Process technicians in the loading area had the second highest mean exposure at 64ppm. Mean area concentrations in those work environments measured during normal operating conditions were found to be below 2ppm, with the exception of the laboratory area used to conduct dry analyses which had a mean concentration of 5.1ppm. Recommendations are made to lower the exposure levels at this facility.
