HARTFORD, Conn. (WTNH) — Firefighters in Hartford battled a damaging apartment fire at 280 Collins Street early Sunday morning.

Officials said the initial call came in at 3:53 a.m. Fire crews battled the blaze for nearly an hour and a half.

12 fire companies responded to the fire which started on a 4th floor unit.

Firefighters said they performed two searches for residents and were able to evacuate roughly 100 residents. 47 of the 54 apartments were occupied.

Two or three civilians were transported to a local hospital for shortness of breath and one firefighter was transported for minor injuries.

Firefighters contained the fire to the apartment of origin.

Fire Chief Reginald Freeman told News 8 the building suffered “water damage, dry wall damage and electrical system issues due to the copious amounts of water that flowed through the building.”

It is still unknown when residents will be able to return to their apartments permanently.
