I had a burly 230 lb Groundman who knicked the femoral artery in his leg with an 044. Luckily I got to him in time to apply a tourniquet ( speedline loop n biner ) and cinch it down hard enough to stop the profuse bleeding.
The nightmare was getting him into my tooltruck, took four of us, then driving him to the nearby hospital ER in time to save him. We were in La Jolla, less than a mile or so from Scripps Hospital. But as often happens, fate n bad luck did its best to screw me over that day, since Torrey Pines Rd North was closed off for repaving.
Just as I realized how screwed my situation was due to the road closure, the groundie who'd cut himself passed out, let go of the biner keeping the tourniquet tight, and started spraying blood onto the passenger seat n floor of my truck. Furious at my compounded bad luck, I put my truck in second gear, reached across with my right hand, twisted the biner tight enough again to stop the bleeding, ran the red light at Genesee and Torrey Pines Rd, took the first right off Genesee into a research institute that I knew was only two bldg's south of the hospital, then four wheeled my truck through the parking lots of the two institutes separating me from the hospital, jumping curbs, busting through xylosma hedges, up onto the front lawns, then onto Torrey Pines Rd South which was open, but I had to go north on it against traffic to reach the ER entrance. Couldn't even blow my horn since both hands were full, one to steer, the other holding the biner tight.
Fortunately I made it right up to the ER doors, where upon the orderlies there got a gurney stretcher and got the passed out groundie onto it without me ever having to let go of the biner as I clamored over the gear shift and out the passenger side of my truck.
Dude lived, but quit the tree biz. Took me over a month to get my speedline loop n biner back though!
The ER doctors congratulated me on my make do tourniquet, and assured me that without it, dude woulda bled to death for sure.
Landscape crews at the two southern research institutes had a lotta repairs to do to the hedges n lawns I destroyed though, no doubt.
Tourniquets save lives IME.
