Abstract
In order to assess the extent of worker exposure to 1,3-butadiene (106990), an in depth industrial hygiene survey was conducted at the E.I. duPont deNemours and Company (SIC-2869) in Orange, Texas. This facility had a capacity of 490 million pounds per year of adiponitrile (ADN) by synthesis of 1,3-butadiene and hydrogen- cyanide. Workers' full shift exposures to 1,3-butadiene were below the American Conference of Governmental Industrial Hygienists threshold limit value of 10 parts per million (ppm) and the present Occupational Safety and Health Administration Permissible Exposure Limit of 1000ppm. The only exception was a shipping technician's exposure of 28.5ppm. Arithmetic and geometric mean full shift exposures across all job categories were less than 0.20ppm, except for the shipping technicians whose arithmetic and geometric mean full shift exposures were 14.6 and 4.69ppm, respectively. Under normal operating conditions, airborne concentrations in all work environments were at or below 0.60ppm. The authors recommend that consideration be given to converting to a closed loop sampling system for obtaining quality control readings from barges. A program to convert to 100 percent magnetic gauges should be undertaken to replace those slip tube gauges currently in use.
