SEDONA -- About 3:30 p.m. Thursday, the Sedona Fire District was dispatched to a head-on collision on State Route 89A in Oak Creek Canyon, south of the Trout Farm.
Two minutes later, fire crews began triage and treatment.
A full-size panel van and a Toyota Prius had collided head on. Three ambulances, and a Guardian Air medical helicopter transported four people to Verde Valley Medical Center and Flagstaff Medical Center, two with serious injuries.
The force of the impact caused lengths of rebar inside the van to fly through the front windshield.
Fortunately the rebar missed the occupants, but it serves as a good reminder to the additional risk presented by flying objects inside a vehicle, fire officials advised.
After all patients were transported, Sedona Fire personnel used a solution called biosolve, a hydrocarbon mitigation agent, to safely clean up the fluids and reduce the risk of environmental damage.
The accident blocked both north and south bound lanes of Hwy 89A and the highway remained closed about an hour and a half.
In addition to Sedona Fire, Sedona PD and DPS responded.
