Guys and gals I cannot stress enough like others have said about wearing a harness. I have worked in the refinery business and still work in industrial maintenance, and as part of our PPE (Personal Protection Equipment) we have to have training once a year to stay certified in fall protection. In our training they show the energy that is captured by a weight being dropped. It is amazing the shock that the body could take in a fall. I hope this helps in understanding the importance of using a harness and life lines and other fall equipment. Here is a clip of some of the drop test that they performed. www.bing.com/videos/search?q=sala+d...E91FA933131516CEA851E91FA933131516CEA851
