Abstract
In response to an employee request, an investigation was made of possible exposures to chemicals and metal powders at the Wheel Trueing Tool Company (SIC-353x) in Columbia, South Carolina. Exposures occurred during the manufacturing of diamond studded and diamond impregnated cutting tools. Employees registered complaints of gastrointestinal, neurological, cardiovascular, and respiratory problems along with skin rashes and a metallic taste in their mouths. Four of the 37 air samples collected showed cobalt (7440484) levels exceeding the 0.1mg/m3 limit established by OSHA. Most of the handling of loose cobalt containing powders occurred in the production areas. Six samples revealed the presence of nickel (7440020), three of which exceeded the 0.015mg/m3 NIOSH recommended limit. Excessive graphite (7782425) levels were detected in the carbon room with two of three personal exposure samples registering above 10mg/m3. A questionnaire, preshift and postshift pulmonary function tests, and chest x-rays were administered to workers. No evidence of hard metal disease or mixed dust pneumoconiosis was found. The authors conclude that there is a hazard from exposure to cobalt, nickel, and graphite dust. The authors recommend measures to reduce and monitor worker exposures to cobalt and to establish a medical monitoring program for all cobalt exposed workers.
