Exposure of Workers to Respiratory Hazards at Columbus Coal and Refuse Municipal Electric Plant.
NIOSH 1990 Nov:1098-1105
Bulk ash and dust samples from the Columbus Refuse and Coal Fired Municipal Electric Facility (SIC-4953) were examined for their content of 31 chemical elements, free silica (7631869) and cristobalite (14464461). The facility was divided into 11 major areas for this analysis. The workforce was also divided into different groups. Personal sampling data indicated that exposure patterns were not highly predictable. This was true as the majority of employees did not perform the exact same duties and were not present in the exact same location every day. The major groups, mechanical maintenance, electrical maintenance, boiler operators rovers, and steam operating engineers rovers performed duties that were different from one day to the next. Perhaps the most important factor in the exposure of personnel was the unpredictably variable nature of the refuse which makes it impossible to establish definite exposure trends. A medical screening program was described which is to eventually to establish baseline medical data on all employees followed with an annual medical examination to prospectively follow trends in the health of all employees.
