An overturned tanker truck is leaking compressed liquid nitrogen at northbound Spur 408 at Interstate 20.
Dallas Fire Rescue spokesman Jason Evans said the initial call came in at about 1:30 p.m. Monday. At 2:45 p.m., the tanker truck, its cab facing the wrong direction, is still lying in the shoulder of the spur with liquid nitrogen leaking out of its rear.
"Good thing is that I'm told the compressed liquid immediately turns into gas once it comes in contact with the air," wrote Evans in an email. "Therefore, the only danger is someone coming in direct contact with it."
He was not sure how many gallons were onboard or how the accident happened. Police and fire trucks have blocked off the spur. Interstate 20 was not affected.
Evans said the driver exited safely and that the company is covering the cleanup.
