As part of a larger study to determine the hazards of occupational exposure to acrylonitrile (107131) (AN) site visits were conducted at the Monsanto Chemical Company (SIC-2869) located in Addyston, Ohio. AN monomer was used at this site in the manufacture of polymers and had been so used since 1959. A walk through survey was taken of areas associated with potential exposure and interviews with 67 employees and management personnel were conducted. AN exposures appeared to have been higher in the past than they were at the present at these locations. Chemical engineering improvements had been made in the polymer production process between 1959 and 1978 with a concomitant reduction in accidental releases, and a subsequent reduction in worker exposure. A more substantial decrease was noted in employee exposure from promulgation of the AN standard in 1978 by OSHA. Once this standard was passed, the installation of additional engineering and air pollution controls was accomplished and an increased awareness was noted among employees of the health hazard of AN exposure. This resulted in an increased diligence on the part of the workers in safely performing their tasks.
