#155 - Chem.info update on CO Poisoning in Colorado Mine

The Chem.info website quotes an Associated Press update on the incident involving the recent mining deaths in Colorado, USA. Two miners who died of carbon monoxide poisoning apparently entered an area of the mine where an explosive had been previously detonated, federal investigators said Monday.

Carbon monoxide (CO) is odorless, colorless, and toxic. In a mine it can come from combustion engines and explosives. It can accumulate in an area of a mine at high enough levels to cause injury and death.

Miners have air packs to supply them with oxygen during an emergency. However, it is not certain if the miners had any means of detecting elevated levels of carbon monoxide in that area of the mine.

No doubt the U.S. Mine Safety and Health Administration is continuing to investigate the unfortunate deaths.
