Grizzly Mining Company Grizzly Mine Carbon Monoxide Poisoning
September 6, 1879
No. Killed - 6
Six men were asphyxiated in the Grizzly mine from carbon monoxide. Three of them were killed in an effort to rescue
others. The cause of the accident is ascribed to smoke from the engine furnace on the tunnel level,
the exit of which had become choked, and thereby smoke was driven back through the mine.
