coal dust exposure

The impacts of coal dust on miners' health: A review

Coal mining and processing involve multiple dust generation processes including coal cutting, transport, crushing and milling etc. Coal dust is one of the main sources of health hazard for the coal workers. Exposure of coal dusts can be prevented through administrative controls and engineering controls. Ineffective control of coal dust exposure ...

Coal Mining Safety and Health

The stakes are so high because exposure to coal dust and silica dust is a matter of life or death. Coal mine workers pneumoconiosis, along with other diseases in the coal mine dust lung diseases group, are progressive diseases. They can take over 10 years of prolonged dust exposure to develop even longer to produce symptoms.

The workplace exposure standard (WES) for respirable coal dust has been reduced from 3 mg/m 3 to 1.5 mg/m 3.. Under the model work health and safety (WHS) laws, PCBUs must eliminate or minimise the risks so far as is reasonably practicable, including those associated with chemical exposure.A PCBU must also ensure that workers are not exposed …

NIOSH (Ex. 8-47, Table N2; Tr. p. 3-86) believes that the limit for quartz-bearing coal dust should be reduced to 0.05 mg/m 3 as an 8-hour TWA on the basis of the potential carcinogenicity of respirable crystalline silica. OSHA is aware of some recent studies (NIOSH 1986b; Hurley and Maclaren 1987; IARC 1987) on the health effects of exposure ...

The United States National Institute for Occupational Safety and Health conducted a long-term study of inhalation exposure to coal dust and/or diesel. In rats, exposure to coal dust (2 mg/m 3 for 7 h/day, 5 days/week, over 2 years) resulted in a chronic elevation of alveolar macrophages (Castranova et al., 1985).
