Fire Chief Terry Bell said the fire, reported at about noon, was likely caused by a malfunctioning ceiling fan in one of the living center’s bathrooms.
Bell said more than 40 people were evacuated from the building at 228 Fairbanks Road. They were taken to Mt. Blue High School, also in Farmington.
The Franklin County Regional Communications Center posted on its Facebook page that staff from Edgewood, Northstar Ambulance, Regional School Unit 9 and several fire departments had set up at Mt. Blue High School to provide care for the Edgewood residents.
The fire was knocked down at about 1 p.m., according to Bell.
“The sprinkler system did its job and put most of the fire out,” he said. “Unfortunately, there was a good amount of damage to the building, from the fire and the water used to put it out.”
