 I'm HM3, Jesse the Flesh, and I'm from Missoula, Montana, so today we simulated a sailor. He wasn't wearing a harness, and he was going aloft. And he fell. And when he fell, he ended up injuring his back and his neck. And so that leaves you with a sea spine injury. And then once they were able to get that person on the stretcher, they had to be able to put on the sea collar. And the sea collar is there to stop them from moving their neck more than just holding it there. It stabilizes it even further. And so they were trained on how to put that sea collar on. And then once the sea collar was on, they would strap this person completely into the stretcher and then take him to medical. We have to train on these because you never know what something's going to happen and you never know what type of injury it is.
