FIRE and rescue crews battled "sickly smelling and sticky conditions" to rescue a Gympie man entrapped in a crashed double tanker carrying molasses on Cooyar Road near Oakey on Wednesday.
The 44-year-old man suffered multiple injuries when his double tanker left the winding road, hitting trees and falling down a slight hill, an AGL Action Rescue Helicopter Service spokesperson said.
"The whole area was soaked with molasses, providing a sickly smell as the rescue crews worked on the man," she said.
"The AGL Action Rescue Helicopter was rushed to the accident, landing in a private field just above the accident scene.
"Local fire and rescue crews worked to free the driver entrapped in the cab of the vehicle."
The man was stabilised by flight paramedic Brett Rogers and a doctor at the scene before being airlifted to Royal Brisbane Hospital in the helicopter.
The patient remained in a serious condition Thursday morning.
