HHE determination report no. HHE-76-106-384, Ajax Magnethermic Corporation, Warren, Ohio.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 76-106-384, 1977 Apr; :1-10
A Health Hazard Evaluation investigation was conducted by NIOSH at the Ajax Magnethermic Corporation, a manufacturer of induction heating and melting systems (SIC-3567) such as for use in foundries, in Warren, Ohio, on December 6-7, 1976. An authorized employee representative requested the survey because the workers were complaining of headaches in certain areas of the facility. Environmental air sampling, confidential interview of seven of the 50 affected employees, evaluation of work procedures, and available toxicity information revealed that employee exposures at the burning table in the weld shop to total dust, iron-oxide (1317619), and manganese (7439965) did not constitute a health hazard, although during certain particular operations adequate ventilation should be provided. Employee exposure to total dust and n-butyl-glycidyl- ether (2426086) from an epoxy resin in the Bluecoat Spray Booth did not constitute a health hazard during the survey, although the workes should wear hand protective equipment to guard against dermatitis. In the Scotchcast Room of the Coil Department, ventilation was sufficient and employees wore skin protection, to the effect that a health hazard is not judged to exist there. For safety reasons, recommendations are made to modify the spray painting process.
