Abstract
Environmental and personal air samples were analyzed for the presence of hazardous concentrations of coal and silica (7631869) dusts at the coal fired power facility of the Crisp County Power Commission (SIC-4911) in Cordele, Georgia, on July 12, 1978. The evaluation was requested by the management on behalf of an unspecified number of workers. Noise measurements also were taken. Airborne dust concentrations ranged from nondetectable to 0.15 milligrams per cubic meter (mg/CuM), well below the OSHA standards of 2.4mg/CuM for coal dust and 10mg/CuM for respirable dust containing quartz. Exposures to free crystalline silica were below the detectable limits of the sampling and analytical method. Noise readings ranged from 67 to 116 decibels (dB) at different locations. The OSHA standard for noise exposure is 90dB for an 8 hour daily exposure. The investigators concluded that coal and silica dust concentrations were not hazardous to workers at the time of the investigation, but that some workers were exposed to excessive noise. Recommendations were to wet the coal before it is loaded or moved, and to develop and enforce a hearing conservation program. Procedures for work in confined spaces also are recommended.
