Firefighters battled a blaze at the Sasco Creek Village trailer park on the Post Road East on Wednesday night that left two people homeless.

Firefighters were initially slowed in battling the blaze because fireworks were exploding inside one of the trailers, according to fire officials. Several propane cylinders in proximity to the fire also had to be moved away from the fire.

Assistant Fire Chief Larry Conklin said that a 911 call about 10 a.m. Wednesday alerted authorities to the blaze at the trailer park at 1655 Post Road East, the site of about 60 mobile home units.

Conklin said that the blaze erupted on one side of double-wide Unit 86, which soon spread to the attic of Unit 88. An elderly woman lived on one side and a man lived on the other side, and both had to find other housing, Conklin said.

Firefighters with Truck 1 escorted the occupant of Unit 88 out of her dwelling, while the resident of Unit 86 got out on his own.

The fire also melted the siding on another mobile home, Unit 14.

Conklin said that two firefighters were treated for minor injuries at Norwalk Hospital. The cause of the fire remains under investigation.
