In early April 2010, an explosion in a mine in Montreal, West Virginia killed over 90% of the workers that day and only 2 survived making it the most fatal explosion incident since 1970. The source of the ignition is still unknown but the high flammable methane levels were likely to have been a major contributor to the disaster. Initially, 25 out of the 29 men that were killed were discovered immediately and their deaths were attributed to the explosion or inhalation of toxic gases that resulted. Four more individuals, who were presumed missing, were later identified in the blast debris. The underlying problems with occupational health and safety protocols and processes and the response of the mine management company led to heavy criticism by the families of the deceased and public officials.
