A Health Hazard Evaluation determination was conducted by NIOSH at Bohn Aluminum and Brass Corporation, Heat Transfer Division, Danville, Illinois, during February, May, and July of 1976. An authorized employee representative requested the investigation, to determine whether any substance found in the work area has potentially toxic effects. Some of the more than 70 affected workers were alleged to have upper respiratory irritation, skin rashes, and breathing difficulties presumably due to cutting oil exposure. The operations investigated were copper fabrication (SIC- 3351), fin-press, and brazing. On the basis of environmental and medical data, observation of work practices and available literature on the toxicity of substances used in the work areas, it has been determined that exposure of brazers to cadmium (7440439) fumes are potentially toxic at concentrations measured during the survey (up to 0.366 milligrams per cubic meter). Although exposures are sporadic, the fact that cadmium accumulates in the body over the years and that the long term effects of this accumulation are not well understood make it advisable to limit exposure to cadmium as much as possible. Exposures to fumes of copper (7440508), zinc (7440666), and silver (7440224) were found to be nontoxic. It is believed that exposure to Mac Stamp 68, the tooling lubricant, will not produce any long term health effects, although vapors of this solvent may produce transient eye and respiratory irritation; however, direct contact with the solvent could dry and defat the skin. At the concentrations measured, concentration of 1,1,1- trichloroethane (71556) and of fluorides in the air were nontoxic. Recommendations are made to control or minimize existing hazards.
