Health Hazard Evaluation Report HETA 88-348-2081, A.E. Staley ManufacturingCompany, Decatur, Illinois

摘要

In response to a request from the Allied Industrial Workers of AmericaInternational Union, an evaluation was conducted at Staley Company (SIC-2046), Decatur, Illinoois to investigate emissions from the waste water treatment facility and exposures to asbestos (1332214). The company processed 160,000 bushels/day of corn into starch and syrup products. Twenty one of 66 employees who completed a health questionnaire had experienced some symptoms due to waste treatment facility emissions. However, no detectable emissions likely to cause these symptoms were detected in the waste treatment facility. Area and personal breathing zone samples for propylene-oxide (75569) were collected in the starch processing areas and registered as much as 2400 parts per million (ppm) in a 55 minute sampling period due to a fracture in a glycerol seal on the reactor vessel. After repair of the seal, concentrations ranged from 7.4ppm down to nondetectable. Area air samples and personal breathing zone samples indicated an excessive exposure to vinyl-acetate (108054) in the starch vinyl-acetate processing building. The asbestos screening program at the site was in compliance with NIOSH and OSHA recommendations. The authors recommend improvements in employee work practices and the respiratory protection. Engineering controls are also suggested.
