Cause of arc flash and fire at power plant determined
A brief explosion created by an "arc flash" from a 600-volt electrical panel that seriously injured a Ware River Power Inc. (Massachusetts) employee was accidental, investigators from the state fire marshal's office have concluded.
Another employee suffered serious injuries, and a third worker, although hospitalized, returned to the scene the day of the April 17 electrical fire to assist investigators, a report provided by the fire marshal says.
