I have also seen the photo of the busted baw bag , did make me wince . I have never seen a harness save a potential fall . On a working at height course ( another one ching ching ) the guy showed us a video from Norway , two guys fixing a crane . The jib broke with one guy attached to it , he died on impact the other guy was attached to the main frame and was left dangling for twenty minutes , on rescue they thought it unwise to release the tension on the harness in case the rush of blood killed him . Unfortunately the lack of movement of blood was the real issue . The guy died one hour after rescue .
Always remember a harness may save your life on the other hand it has the potential to kill you , the upshot is watch what you attach to and DON`T FALL .
