REHOBOTH, Mass. (AP) – A second electrical lineman injured after his crew’s equipment contacted live power lines Monday has died.

Walter Shaw, 44, died Tuesday afternoon at Rhode Island Hospital in Providence where he had been taken when critically injured, hospital spokeswoman Polly Stiness said Wednesday. On Monday, Joshua Ladd of Belfast died at Morton Hospital and Medical Center in Taunton.

The men were part of a crew doing maintenance work on high-tension lines on Baker Street near Hornbine Road when a crossbeam they were attempting to install accidentally contacted a 115,000-volt line, said James Christensen, director of safety for Par Electrical Contractors of Kansas City, Mo.

Four other crew members were either treated at the scene or at Charlton Memorial Hospital in Fall River.

The workers were subcontractors for Massachusetts Electric employed by Par, said Amy Atwood, a spokeswoman for National Grid, the utility’s parent company.

The accident is under investigation by local and state authorities and the federal Occupational Health and Safety Administration. Two inspectors for OHSA were at the scene on Tuesday to determine what safety rules applied to the work site and whether the workers were complying with safety regulations, said Ted Fitzgerald, a spokesman for the agency.

Area municipal electric line workers said the accident should serve as a reminder of the dangers of their jobs.

“What a lot of people don’t realize is the absolute danger of this line of work. People see a squirrel running around and birds on the lines. It all just looks so innocent,” Gary D’Ambra, the senior crew chief at the Mansfield Electric Department, told The Sun Chronicle of Attleboro.
