The Hawk's Nest Tunnel Incident
The Hawk's Nest "Incident" was not a coal mining disaster but it has been called the worst industrial disaster in the history of the United States. The incident occurred in 1930 with the drilling of the three mile hydro-electric water diversion tunnel. It was built to supply power to a Industrial complex on the nearby Kanawha River. The tunnel was dug through high grade silica rich sandstone which when drilled produced a very fine dust, that when breathed, was comparable to inhaling finely ground glass particles into the lungs.

New Coal Dust Rule: Stakeholders Meeting
As of February 1, 2016, mine operators will be required to use the Continuous Personal Dust Monitor (CPDM) to sample for respirable coal mine dust on working sections of underground coal mines and other areas approved by the District Manager.
All who sample, maintain or calibrate CPDMs must complete an MSHA Course of Instruction, pass an examination, and be certified by MSHA. For the convenience of operators and miners, MSHA is scheduling courses of instruction and certification exams at locations across the country. Each class and exam, held separately for Sampling and for Maintenance & Calibration, will last about 8 hours.

Final Rule: Occupational Exposure to Respirable Crystalline Silica
The Occupational Safety and Health Administration (OSHA) is amending its existing standards for occupational exposure to respirable crystalline silica. OSHA has determined that employees exposed to respirable crystalline silica at the previous permissible exposure limits face a significant risk of material impairment to their health.

Dust Control in Hard Rock Mines
Dust can cause health related issues whether it is a short acute related health problem or a long term systemic problem like silicosis. Prevention of dust is everyone's problem. We all breath the same air, if we don t take care of it. In other words: It can kill you. |
