Canton firm faces fine in fatal explosion

Federal regulators have fined a Canton electrical subcontractor $4,900 for an underground explosion that killed a worker in Waterbury, Conn., earlier this year.

The Occupational Safety and Health Administration cited American Electrical Testing Co. for ‘‘serious’’ safety violations that caused the underground explosion, which killed one of its electricians.

American Electrical was hired by Connecticut Light & Power for maintenance work on its underground system in downtown Waterbury.

David Squires, assistant area director for OSHA, said today that American Electrical has until about Sept. 10 to contest the decision.
