I have never applied one in my varied careers, just the opposite! I evacuated a traumatic near amputation ( crushed ankle ) from a fishing boat.The crew had applied a tourniquet. There was no apparent blood flow. I did determine a perfectly viable artery to the foot was restricted and restored blood supply ( under an Orthopedic Surgeon's radio supervision.)Twice I have been dry bit by Pacific Diamondbacks. Twice some fool wanted to tourniquet my leg and carve Xs with a Rambo knife- after they tried to kill the poor snake over my protests <img src="images/graemlins/mad.gif" alt="" /> Does stuffing a sock in these character's mouths count? <img src="images/graemlins/grin.gif" alt="" />
