A two-person investigative team from the U.S. Chemical Safety Board (CSB) will arrive today at the site of a fatal explosion at a rural Ohio oilfield, approximately 60 miles northwest of Columbus, according to a statement issued by the CSB.

The explosion, at a facility operated by Canada-based Mar Oil Company, killed two contract workers who were reportedly involved in welding near an oil storage tank, according to CSB.

'This latest tragedy comes less than two weeks after a welder was killed and others were injured by an oil tank explosion in Honolulu,” said CSB Chairman John Bresland in the same statement. “Our team will seek to determine if there are similarities between the accident in Ohio and previous cases involving welding in the vicinity of flammable storage tanks.”
