PHILIPPI, W.Va. (AP) — Another person has been killed in an explosion at a West Virginia industrial plant where two people were killed last month, authorities said Tuesday.
Officials said the explosion Tuesday morning was at Midland Resource Recovery, a company based in Ontario, Canada, that odorizes natural gas.
In a preliminary report, the West Virginia Department of Environmental Protection said contractors at the facility outside Philippi were disassembling a 30-gallon (115-liter) tank, trying to render tanks safe from the previous explosion May 24 that killed two and injured one.
The agency says a preliminary report shows one other person was injured and an unknown quantity of Mercaptan, the chemical used to give natural gas an odor, was spilled.
A woman who answered the telephone at the company's headquarters in Ontario declined to comment.
The Occupational Safety and Health Administration has begun an investigation. OSHA spokeswoman Lenore Uddyback-Fortson said the victim was an employee of Specialized Professional Services Inc.  The company based in Washington, Pennsylvania, handles hazardous material. Calls to the company were not immediately returned Tuesday.
