Chelsea and Federal Occupation Safety and Health Administration (OSHA) officials are investigating a morning accident that injured two construction workers at a Bellingham Square worksite last week.
Police report that two workers of Tuffs Incorporated of Medford were working below street level in an excavated worksite when their equipment came into contact with an electrical line causing an explosion.
Both workers were pulled from the site and escaped serious injury.
One of the injured, a 50- year- old Everett man was transported to Massachusetts General Hospital but luckily his injuries were not reported to be life threatening. The second injured worker a 27- year -old Everett man was treated at the scene. The accident caused the busy section of downtown to be closed until the worksite was cleared and motorists were asked to avoid the area.
The incident also affected Logan Airport. Massport officials say the electrical source for Logan feeds through Chelsea.
The power went down briefly the morning of the accident, forcing the airport’s back-up power sources to kick in.
