Workers suing companies over CT plant blast

Attorneys for nine people injured or killed in a Connecticut power plant explosion say they're suing companies involved in building and overseeing the facility, The Associated Press reports.

The lawsuits allege plant owner Kleen Energy Systems and some contractors failed to take precautions to prevent the February blast. Six workers died and 50 were injured.

The lawsuits are being filed Thursday in Middletown Superior Court.

The under-construction plant in Middletown exploded when something ignited natural gas and air that had accumulated while high-pressure gas was forced through pipes to clean them.

The U.S. Occupational Safety and Health Administration imposed $16.6 million in fines against companies involved in the blast, though the largest companies say they're appealing.
