Firefighters extinguished a fire that broke out at a residential building in Ewa Beach late Wednesday.

Eight units with 27 firefighters responded to the fire at 91-755 Fort Weaver Road at approximately 9:25 p.m. and had put it out by 10:15 p.m.

Upon arrival they observed smoke emerging from the front right corner of the building.

Honolulu Fire Department spokesman Capt. Scot Seguirant said a woman in the home safely escaped, and no injuries were reported.

HFD determined the fire was an accident caused by an impaired 6-foot extension cord. It estimated damage at $209,000 to the structure and $10,000 to the contents. HFD warned the public not to use extension cords as permanent wiring.
