Abstract
An in-depth survey was made of a 1,3-butadiene (106990) monomer producing plant, Shell Oil Company's (SIC-2869) Deer Park Manufacturing Complex, Deer Park, Texas because recent toxicological studies have indicated 1,3-butadiene as an animal and potential human carcinogen. Workers performing maintenance on process equipment had the highest potential mean exposure, 14.46 parts per million (ppm), although this represents a short-term exposure. However, due to the required wearing of respirators, the actual exposure was less. The highest mean area concentration for a specific work environment was 15.78ppm and was found in the loading area during a 2.5 hour loading operation of rail cars. The highest individual area airborne concentration was 64.29ppm, detected near a rail car during a loading operation. All exposures to 1,3-butadiene were well below the OSHA Permissible Exposure Limit of 1000ppm. The authors conclude that the current exposure control programs serve to maintain most 8 hour exposures to less than 10ppm of 1,3-butadiene. Shell is encouraged to continue the program of converting to a closed loop sampling system. Employees doing maintenance activities should continue to use respirators with organic vapor cartridges. Presently both slip tube and magnetic gauges are used during the loading of railcars with 1,3-butadiene. A program to convert to 100% magnetic gauges is being considered.
