NIOSH 1990 Mar:28 pages
An on site visit was made to the Monsanto Chemical Company (SIC- 2869), Alvin, Texas for the purpose of monitoring employee exposure to acrylonitrile (107131) (AN) from facility start up through 1983. AN exposures were much higher historically than they were at the present time. This particular facility began producing AN monomer in 1965. Departments where workers were felt to have a potential to exposure included AN production, distribution, laboratories, environmental control, engineering and maintenance. On a facility wide basis the OSHA standard for AN, promulgated in 1978, had the greatest single impact on reducing AN exposures. The standard resulted in better work practices, better use of personal protective equipment, and the addition of engineering controls to help reduce exposures.
