Abstract
Nickel processing operations at three facilities were surveyed for potential worker exposures to nickel (7440020) and crystalline silica (14808607). The facilities monitored included a nickel smelter (SIC-3339) which pyrometallurgically converted a nickel- oxide ore to a 60 to 60 percent ferro-nickel alloy; a nickel refinery treating imported sulfide ores with acid to produce pure nickel and cobalt as briquettes or powder; and an inorganic chemical facility manufacturing nickel salts and solutions from nickel metal or nickel-oxide. While most of the facilities were continuously below the OSHA standard for nickel of 1mg/m3, none of the samples taken were within the NIOSH recommended limit of 0.015mg/m3. Minor occurrences of excessive silica exposure were noted in the ferro- silicon and ore handling areas with the average concentration being second and third facilities, worker exposure exceeded the American Conference of Governmental Industrial Hygienists threshold limit value for nickel of 0.1mg/m3. With minor renovations these facilities could be brought within this limit. However, major changes would be needed to comply with the NIOSH limit of
