A tanker truck carrying between 7500 and 9000 gallons of gasoline overturned and caught fire as the rig exited I-270 at Montrose Road. Montgomery County Fire & Rescue Services Assistant Chief Scott Graham tells STATter911.com the tractor trailer turned onto the driver’s side around 4:40 AM, but the driver was able to escape unharmed as the truck caught fire.
According to Graham firefighters kept burning gasoline rolling down the road in check with handlines as they let much of the fuel burn off. A foam crash truck from Dulles Airport arrived about 30-minutes into the incident and about a half-hour later was used to extinguish the fire. A second foam unit from Frederick County, Maryland was also on the scene.
Graham says the burning fuel did not appear to impact the integrity of the Montrose Road overpass above I-270 as the fuel run off generally burned away from the structure.
