Occupational Exposure of Workers to 1,3-Butadiene at Monomer Production Plants.
Fajen-JM; Ungers-LJ; Roberts-D
The results of studies of occupational exposure to 1,3-butadiene (106990) (butadiene) at butadiene monomer production factories (SIC- 2869) were presented. Personal and area air samples were collected in seven work areas and for eight job titles during NIOSH in depth surveys at four butadiene monomer production facilities and analyzed for butadiene. Arithmetic mean butadiene exposures according to job title were: rail car process technician 14.64 parts per million (ppm), tank truck process technician 2.65ppm, tank farm process technician 0.44ppm, pump alley technician 2.23ppm, control room technician 0.45ppm, maintenance worker 0.21ppm, laboratory analysis technician 1.06ppm, and laboratory cylinder voiding technician 125.32ppm. Arithmetic mean exposures by work area were: rail tank terminal 11.03ppm, tank car terminal 0.57ppm, tank farm 7.80ppm, pump alley 0.50ppm, control room 2.13ppm, laboratory 1.14ppm, and ambient air 0.08ppm. The authors conclude that 95 percent of these workers have full shift butadiene exposures of less than 5ppm, well below the OSHA permissible exposure limit of 1000ppm. Among butadiene monomer workers, those required to handle or transport containers are at greatest risk. Relatively low exposures to butadiene exist in the butadiene monomer production industry.
