HHE Report No. HETA-91-0142-2434, Dee Zee Manufacturing, Des Moines, Iowa.
In response to a request from employees at Dee Zee Manufacturing (SIC-3429), Des Moines, Iowa, concerning exposures to hazardous materials in and around the buffing shack area, an environmental and medical survey was conducted. The company manufactured after market truck accessories such as running boards, brush guards, and roll bars. Overexposures were found to total dust, welding fumes, aluminum (7429905), chromium (7440473), carbon-monoxide (630080), nitrogen-dioxide (10102440), and sulfur-dioxide (7446095) for buffing and welding employees. All employees were overexposed to carbon-monoxide. Buffers and welders reported similar prevalences of shortness of breath, chest tightness and wheezing, but the buffers had higher prevalences of skin rashes, nosebleeds, ear pain, eye irritation and sneezing. Foreign objects in the eyes occurred more frequently among the welders. Eight of the current employees had pulmonary function results below normal limits. All eight exhibited obstructive respiratory disease patterns. Two of the eight were buffers; six were welders. All were either former or current smokers. The authors conclude that a health hazard existed from exposure to dust, welding fume, aluminum, chromium, carbon- monoxide, nitrogen-dioxide, and sulfur-dioxide. The authors recommend that medical surveillance and exposure reduction measures be taken.
