HETA Report No. TA-73-23, Cincinnati Gas and Electric, Miami Fort Station.
NIOSH 1973 Apr; :1-3
This letter advised the Cleveland Wrecking Company, Cincinnati, Ohio, that a study of asbestos (1332214) exposure has been made, at their request, at the Cincinnati Gas and Electric Miami Fort Station. Workers were in the process of removing insulation from a boiler at the time four personal breathing zone samples were taken, extending over a period of about 0.5 hours. During the removal operation, one worker continually sprayed the boiler with water, thus minimizing the amount of dust generated by the other worker who was removing the insulation. Respirators were worn by these workers. Persons were engaged in this type of activity for only 4 to 8 hours per week. At no time were workers found to be exposed to levels of asbestos fiber which exceeded the Department of Labor allowable limit of 5 fibers/cubic centimeter (f/cc). No distinction was made between fibers of asbestos and glass (14808607). The concentrations for fibers of asbestos and glass together ranged from present at the site and encourages the continued use of both respirators and the wetting process when this activity is being performed.
