The owner of a Massachusetts power plant where an explosion killed three workers has been cited for federal safety violations.

The Occupational Safety and Health Administration on Wednesday cited Dominion Energy New England. The agency says it failed to take effective steps to protect employees against burn hazards and other injuries.

The company has been issued 10 serious citations that carry a proposed fine of more than $46,000.

Dominion spokesman Jim Norvelle says the company will fight the citations.

A boiler tube ruptured at the Salem Harbor Power Station in November and blasted three workers with steam.

Regulators say the affected area had not been entered in more than nine years.
