Green Bay firefighters say a home's electrical wiring was overtaxed by multiple space heaters and appliances, causing a fire in the attic of a home Thursday morning. The fire department was dispatched at 8 a.m. to a report of smoke in the attic of a home on the 500-block of La Plant St., on the city's east side. Firefighters saw smoke coming through the roof vents and the attic filled with smoke. A thermal imaging camera found the hot spot in the ceiling area. Firefighters were finished with the job in 30 minutes. Damage was estimated at $25,000. Four people who lived in the home are receiving help from the American Red Cross. The Green Bay Metro Fire Department is reminding people to never use a power strip with space heaters and follow manufacturers' safety warnings.
