We worked a wreck in a town that I lived in. the car got smashed in front pretty good then rolled off into a field. The dashboard intruded into the passenger compartment trapping and elderly man's right leg, he was unconscious. the fire department rolled up first and deployed the jaws of life. Running to the car with the spreaders as the hose peeled off of the 100 foot reel. The firefighter began trying to get a purchase on the bent dash from underneath to lift it. One of our medics arrived and looked, he said, "I know this guy, he works at Walmart, that's a prosthesis." He took out his shears, cut the pants leg and removed the straps. Then they slid him out onto a spine board, "Get that leg out and bring it to the hospital." Bob said. Imagine the embarrassment had he not shown up and they spent 10 - 15 minutes gently lifting the dash to free an artificial leg. Next?
