DRACUT — Dozens of firefighters battled a large fire at a Dracut home in heat and humidity Thursday morning.

A blaze broke out at 62 Methuen Road shortly after 9 a.m. Thursday morning, according to Dracut Deputy Fire Chief Rich Patterson.

None of the home’s occupants were injured, while one firefighter suffered a minor muscular injury, although Patterson said the conditions were difficult as outdoor temperatures creeped into the high 80s.

Occupants called 911 when they noticed smoke. Patterson said the fire came from an electrical panel, although authorities are still investigating the full cause.

The fire had spread into the attic, causing flames to reach up through the top of the building. A large hole in the roof was visible once the blaze was under control, while debris appeared to fill the building’s garage.

Paul Borriello, who owns the home, said his wife was in the building when the fire started but escaped safely. He rushed home to see “smoke out of every window” and “flames out of the roof.”

Borriello had lived in the house for four decades.

“I’m glad no one got hurt, but it’s hard when you build a house brand-new 40 years ago and watch it burn,” he said.
