An industrial hygiene survey to assess personnel records and possible exposures of persons involved in the use of acrylonitrile (107131) (AN) at the Monsanto Company Fibers Division, Decatur, Alabama, is reported. The plant is involved in the manufacture of acrylic fibers, polyester staple, nylon tire yarn, nylon staple, nylon intermediate chemicals, polyester flake, polystyrene plastics, and ChemCoke (SIC-2824). The nylon intermediates manufactured are adiponitrile (111693) (ADN) and hexamethylenediamine (124094) (HMD). Personnel exposure sampling is done routinely under the direction of the plant industrial hygienist. Personnel exposure measurements taken during 1977 were below 5ppm with one exposure at 10ppm. Cases of people exposed to AN exhibiting medical symptoms have been noted by this plant. In addition, extensive medical records have been maintained on current, terminated, and retired employees. It is suggested that this plant is suitable for epidemiological studies because: 1) exposure to AN is distinct; 2) the plant has been in operation a considerable time; 3) the population is large; and 4) the record-keeping system is good.
