The Honolulu Fire Department has determined unattended smoking materials found in a bedroom caused a fire at a home in Ewa Beach.

At about 4:28 p.m. Tuesday, more than 20 firefighters responded to the fire at a two-story home at 91-1320 Kamahoi St. When they arrived, they observed black smoke emerging from the second-floor window of a bedroom.

Five people who were inside the home safely escaped the residence before firefighters arrived. Firefighters brought the blaze under control at 4:46 p.m. and extinguished it within 10 minutes.

No injuries were reported.

Honolulu Fire Spokesman Capt. Scot Seguirant said ashtrays, lighters, packs of cigarettes and other smoking materials were found in the bedroom where the fire originated.

Damage was estimated at $187,000 to the structure and $8,000 to its contents.
