Health Hazards Evaluation Determination Report No. HHE-77-117-444, Eaz -Lift Towing Systems, Elkhart, Indiana.
A survey team from NIOSH conducted a health hazard evaluation on September 9, 1977, at EAZ-Lift Towing Systems, Inc., Elkhart, Indiana at the request of an authorized representative of the employees. The conclusions and recommendations presented in this report are based on environmental measurements, observation of the workplace and work practices, medical questionnaires and a review of current literature. Airborne concentrations of contaminants form the welding operation, notably iron, nickel, chromium, manganese, and total particulate, were collected in the workers' breathing zone. The airborne contaminant concentrations measured were found to be within acceptable limits of exposure with the exception of two workers, who exceeded the recommended criteria for total welding particulate. Environmental and biological measurements for worker exposure to carbon monoxide were taken. All measurements for CO were within acceptable limits. Information obtained form medical questionnaires indicated that half of the workers interviewed have a cough and/or congestion which they feel may be due to their exposure to contaminants generated by the welding operation. The potential for overexposure of employees to welding contaminants exists in this welding operation Recommendations for the alleviation of this hazard are presented in this report.
