Hunter Safety System sends an extra strap with their harness that has a loop in one end. If you fall, you just put your foot in the loop and step up, thereby relieving the pressure on your lower legs. Always, always, always keep your cell phone on your person so if something does go wrong, you have access to it as opposed to it being in your pack or somewhere else you can't get to it.
