Makes you wonder, why skydiving instructors even need Insurnace…Perhaps it's Allah's will that we not survive a major bleeding event. As has been pointed out, we always have something that will work as a tourniquet with us. In a half century of diving I've never seen a major bleeding event. I've been around two fatalities and a few near misses, but in every case it was someone's stupidity. Sport diving is an adventure. There is nothing wrong with some danger. I used to sky dive, and never once did I see a medical emergency or need a tourniquet.
