im currently inducting 400 men with a supension trauma / intolerance , self rescue is the key when u can , or getting in to a sitting positon , with straps or improvisation , as have spanner said , spinal injuries are a big issue , when the average mans height the line and the shock absorber together comes in to work , u r looking around 4 m 70 fall , and that in itself is enough to cause spinal injury , u re body weight comes six times more , average of 6kn when u come under , a lot of pressure on the arteries , rescue plan in place and with emergency services on site ,
its more likely that your mates will help u our site is 15 km by 11 km so time flies when ure hanging about , theres lots of info on the web many conflicting accounts , but the facts are there , we have all trades inducted in orthostatic intolerence and have our own rescue team .
