Abstract
A Health Hazard Evaluation investigation was conducted by NIOSH on January 17-20 and May 25-26, 1977, in the Pickling and Chipping Dock of the Inland Steel Corporation, East Chicago, Indiana, a facility involved in removal of defects from steel billets and blooms before being processed in a rolling mill (SIC-3312). The survey was prompted by a request from an authorized employee representative regarding exposures of approximately 70 affected workers to crystalline silica (7631869), lead (7439921), sulfuric-acid (7664939) and contaminants released from abrasive grinding operations. Environmental sampling revealed excessive lead exposure when lead containing steel was cut with an oxyacetylene torch. The airborne concentrations of all other contaminants were not potentially toxic, a finding supported by the lack of complaints and symptoms. Review of medical questionnaires revealed previous symptomatic conditions (respiratory irritation, eye irritation, dermatitis and dental anomalies) compatible with exposure to sulfuric-acid. Recommendations are made for maintaining a safe and healthful work environment.
