A trash compactor fire was extinguished in a New Canaan Avenue facility on Saturday, officials said.

Firefighters responded around 4 p.m. to Broad River Homes, an assisted living facility at 108 New Canaan Ave. for a report of a fire in the trash compactor, Assistant Fire Chief Chris King said.

The fire was contained to the trash container and chute thanks to an activated sprinkler head. Fire department personnel completed putting out the flames that remained.

Many residents self-evacuated the building after the fire alarm sounded and were later taken to the second floor community room because of the cold weather.

Residents who couldn’t self-evacuate were checked on by fire personnel to ensure their safety.

Firefighters ventilated the building, and all occupants were able to return to their apartments.

The cause of the fire remains under investigation.
