A Health Hazard Evaluation investigation was conducted by NIOSH on May 1, 1975 at the Transportation Products Division, National Steel Corporation, Portage, Indiana, a facility engaged in the production of nailable steel floorings (SIC-3316) for railroad cars. The survey was prompted by a request from an authorized representative of the 21 affected employees regarding lack of ventilation in the production welding area which allegedly causes high exposure to welding fumes in employees working in adjacent areas. It was determined that production welders were exposed to iron-oxide (1317619) fumes in excess of the Threshold Limit Value established for this effluent. This conclusion is based on breathing zone measurements and medical questionnaires completed for affected employees which provided evidence for the development of acute respiratory and eye irritation over the work shift. Recommendations for improved environmental control measures and work practices are outlined.
