Fireman shares his rescue story
Fireman Alex Hardee worked side-by-side with other rescuers.
"Four hours for me. That’s a first," Hardee said. "That’s the longest that I have probably been a part of," Hardee said.
Authorities said the trucker’s leg was so badly damaged, paramedics considered amputating it on the scene.
Hardee climbed into the rig in full turnout gear on a blistering hot day.
"Your body temperature, no matter how much you sweat, you can’t drink enough water," Hardee said.
Fire crews took turns so that they didn't overheat, going up and down a steep hill.
Cables from a large wrecker kept the truck from sliding further down hill.
"We have a job to do. We signed up to do this. We trained for this," Hardee said, adding for four hours firefighters and police focused on the trucker trapped inside.
"Keeping him abreast of the steps were taking to extricate him. Just more or less talking to him and keeping him calm," he said.
They had to remove the floor of the rig to pull him out. Hardee helped to take him back up the hill to a waiting medical helicopter.
"We were excited. We were glad that he was out. Then we got right back into the mode of, ‘We got to get him out of here,’" Hardee said.
They saved his life, but the damage to his leg was too severe. Doctors at the hospital amputated his leg. One officer said it’s still a success and that in 29 years he has never had rescue last so long and have the patient survive.
