In response to a request from the International Brotherhood of Firemen and Oilers Union, an evaluation was made of possible health hazards at the Carbon/Graphite Group (SIC-2819), Louisville, Kentucky. The request indicated that 30 to 40 workers were possibly exposed to carbon-monoxide (630080) in areas of the facility where calcium-carbide was manufactured and handled. Results of personal exposure monitoring indicated carbon-monoxide levels of 9 to 82 parts per million (ppm) as full shift, time weighted averages. Several peaks above 200ppm were noted; acetylene interference was a factor in the high readings in some areas. Complaints from individual workers did not reveal any symptomatology which would be compatible with carbon-monoxide exposure. The author concludes that a health hazard was not found at the time of the evaluation, but there was a potential hazard for carbon-monoxide exposure during equipment failures or entry into confined spaces. The author provides recommendations concerning carbon-monoxide monitoring in the scrubber area, the crusher area, and the furnace area; engineering controls for dust, personal protective equipment and other inhalation hazards; and confined space entry.
