Fire officials said two electrical workers employed by a Billerica (MA) subcontractor were seriously injured Wednesday morning in an explosion at a construction site, according to a report in the Lowell Sun (http://bit.ly/uI27yu).
Andover Deputy Fire Chief James Dolan said firefighters received a call at 10:09 a.m. from Mayo Clinic Medical Laboratories at 169 Dascomb Road. He added that two electricians were reportedly working on a high-voltage panel at the time of the explosion.
One electrician, who suffered first- and second-degree burns to his face, was transported to an area hospital. The other, who Dolan said suffered more severe burns to his face, neck and arms, was initially transported to the same facility but wound up being driven via a life-support ambulance to Massachusetts General Hospital in Boston.
Dolan said his injuries were severe enough to warrant the use of a Med-Flight helicopter, but poor weather had grounded flights. The workers were not identified.
According to fire officials, the workers are employed by Billerica-based Interstate Electrical and were part of a crew tasked with renovating part of a building occupied by the Mayo Clinic. The electricians were reportedly prepping the building to be occupied by Belgian-based Agfa.
