A person standing near the 18-wheeler and the driver of the pickup went to the hospital with minor injuries.
The diesel tanks of the 18-wheeler ignited, but the reason for the long delay was that the acetone had to be transferred to another truck.
"The diesel tanks on the tractor-trailer did rupture. The diesel is what we saw burning," said Vance Mitchell with the Pasadena Police Department. "Apparently, the tanker itself never ruptured so there was no imminent danger at that point other than had it ruptured. It could have been much more severe."
Highway 225 westbound at Red Bluff finally reopened just before 9am.
