They tell us a medical transport vehicle overturned and several tanks of liquid oxygen began leaking. That concentrated liquid form of oxygen has a potential for an explosion when it comes in contact with a petroleum-based product, such as a highway.
A Cherry Point haz-mat crew sprayed down the highway and van with water to keep them cool until the oxygen dissipated.
Two people were injured in the crash, but their injuries were not believed to be serious.
The Realo transport van had no patients on board and another vehicle was involved in the accident.
State Trooper Joe Tucker was patrolling the work zone from the shoulder of the road. He saw it all through his rearview mirror. "I saw a blue truck swerve to the right and at that time struck a white van. It forced the van to the left and caused the van to roll over on its right side," Trooper Tucker told WITN.
