ARLINGTON, Va. (WUSA9) -- A hundred apartments at the Lockwood House in Fairfax County were evacuated on Friday due to a fire. Now, we know what caused the fire.
Fairfax County Fire and Rescue Department officials say investigators determined the cause of the fire was an electrical anomaly involving the underground natural gas feed within the building. Firefighters who responded to the scene that night at 600 North Madison Avenue encountered fire coming from an outside transformer. Fire spread into the first floor electrical room of the four-story, independent living apartment building, say officials.
Firefighters from Fairfax County and Arlington used hose lines to control the gas fed fire until all gas and electrical utilities could be controlled, report officials.
Firefighters went door-to-door checking for residents and helping them get out. Residents were sheltered in a nearby church and a cafeteria, according to officials.
The Office of Emergency Management, Red Cross, and building management personnel assisted in sheltering all the residents, say officials.
One occupant was transported for a non-life threatening injury unrelated to the fire, note officials.
On Sunday, power was restored and all residents were able to return, say officials.
Officials say the damage is estimated at $500,000.
