Two firefighters sustained minor injuries battling an apartment fire Tuesday that damaged a building at the Vista Ridge apartments in Farmingville, fire officials said.

Four apartments were condemned and 11 people were displaced due to smoke and fire damage, Brookhaven Town chief fire marshal Chris Mehrman said.

Mehrman said the fire, which started in a vacant apartment, was caused by a maintenance worker using a plumber's torch. He said the fire was caused by accident and no charges will be filed.

Three families were displaced by the fire, and the Red Cross on Long Island was assisting them in finding shelter, fire officials said.

About 75 firefighters from the Selden, Coram, Farmingville, Terryville, Centereach and Setauket fire departments battled the blaze, which began in a first-floor unit but quickly spread to the second floor, a Selden Fire Department spokesman said. Additionally, Ronkonkoma, Medford and Gordon Heights provided mutual aid.

The fire was reported just before 3 p.m.

It took about an hour for volunteers to bring the fire under control, using "multiple hose lines" and aerial devices.

Both of the injured firefighters were treated and released from Stony Brook University Hospital, the Selden fire department spokesman said. A Selden firefighter was treated for exertion and smoke-related injury; a Centereach firefighter was treated for a hand injury, the spokesman said. Mehrman said 13 residents of four neighboring apartments returned to their homes. Repairs to damaged apartments were underway, and "people will probably be back in their apartments in a couple of weeks," he said.
