TEMPLE – A 24-year-old man was listed in good condition Tuesday at a Massachusetts hospital after he was burned while trying to put a fire out in an upstairs room of a house at 747 Intervale Road house.

James Harris attempted to put the fire out with a fire extinguisher and in the process suffered second- and third-degree burns on his body, including his arms and hands, fire Chief George Blodgett said.

Harris was taken by ambulance to Franklin Memorial Hospital in Farmington and then flown by medical helicopter to Massachusetts General Hospital in Boston, Blodgett said.

Harris’ girlfriend, Lisa Jacques, 39, was also burned in the fire, Harris’ half-brother, Cecil Harris said.

Jacques burned her hand and was taken to FMH by Farmington Fire Rescue Department Chaplain Stan Wheeler, who stayed with her and then brought her home, Blodgett said.

“She was quite impressed with that,” Blodgett said.

The fire started as a chimney fire, he said, but spread into the wall. A blocked outlet for a wood-burning stove got too hot and ignited flammable materials that were against the wall.

It caught the whole room on fire, he said.

The blaze was reported at 12:06 a.m.

The house is owned by Harris’ mother, Rhonda Harris of Chesterville, who has insurance on the house, Blodgett said.

Harris’ condition was listed as good at the Boston hospital, a spokeswoman there said Tuesday. Cecil Harris said that his brother was doing OK.

Harris managed to keep the fire contained to the spare room with the extinguisher until firefighters arrived on the scene, Blodgett said.

The couple was coming down the stairs in the two-story older-style house when firefighters arrived and the couple told them where the fire was, he said.

The upstairs had very dense smoke with some flames in the spare room when firefighters arrived, he said. Firefighters were able to vent smoke from the room through a window, he said.

Blodgett said he believed both of the couple’s pet cats survived.

Fire damage was contained to one room with smoke and water damage throughout the upstairs.

There was also some smoke damage downstairs, he said.

State fire investigator Chris Stanford visited the fire scene Tuesday and confirmed that the fire was caused by an accidental chimney fire, Maine Fire Marshal Sgt. Joel Davis said.

About 25 firefighters from Farmington, Temple and Wilton responded to the blaze with at least six trucks, Blodgett said.
