ALEXANDRIA, Va. (WUSA9) -- Fire investigators are still looking for the cause of a six-alarm fire that injured four firefighters in Alexandria
The fire started at a warehouse located on 801 Pickett Street at approximately 11:49 a.m. Monday. Smoke could be seen from Northeast, DC.
The fire call escalated to three alarms almost immediately. When firefighters began to enter the building, a section of the roof at the warehouse began to collapse. It was upgraded to a 6-alarm fire shortly afterward. More than 200 firefighters responded to the scene.
Firefighters encountered a problem trying to fight the fire because of a water main break from earlier in the day that also happened on Pickett Street. They were able to find alternate water sources and avoid a long delay.
Four firefighters suffered minor, non-life threatening injuries.
WUSA9's Bruce Johnson reports carpets and carpet pads are fueling the fire that's burning in the building.
The fire was put out around 4:25 p.m.
No one was inside the warehouse during the time of the fire.
The cause of the fire is still not known. Chief fire Marshall Robert Rodriguez said in a press release, "We won't have cause for at least a week ...We're working with ATF. They have a great deal of experience with major fires."
