MANCHESTER — Wind-whipped flames tore through part of a triple-decker in the West Side on Saturday night.

The two-alarm fire at 485 Dubuque St. displaced about a dozen residents, according to District Fire Chief Al Poulin.

“About 25 percent of the third floor was totally burned out,” Poulin said. The second floor sustained minor fire damage.

Poulin said first-arriving firefighters encountered heavy fire at the rear of the building, located north of Amory Street. The fire, reported at 9:20 p.m., took nearly an hour to bring under control.

Poulin said the second alarm was called because of the windy conditions and the close proximity to other buildings. The fire extended into the walls and roof, he said.

The cause remained under investigation, and no injuries were reported.

Poulin said firefighters experienced an estimated 30-second delay in responding because they received a wrong address of 48 Dubuque St.

He didn't know how many residents were home at the time of the fire, but all escaped safely.

Robert Berthiaume, who lives on nearby Amory Street, watched as firefighters tamed the flames.

“They had heavy flames coming up from the wind,” he said. “The wind kept igniting it.”

He said firefighters working in chilly conditions got a handle on the flames, then “all of a sudden the flames came up and shot up.”

Watching the firefighters, he said, “A lot of danger up there.”
