Posted By garyh When I managed a scaffold company, I addressed this issue. So:- If the scaff was conscious, he could self rescue. If unconcious you need to rescue quickly, within 20 minutes, they can die with venous pooling. So, you have simple kit available. The Spanset "gotcha" kit comes to mind. The scaff should preferably have a dorsal D ring on his harness; he will be supended by this. Rescuer is above him and uses a telescopic pole to attach a snap fastening to this D ring. Snap fastening is attached to a long rope and to a "turfer" (ratchet pulley device). Rescuer then uses his body weight to operate the "turfer" which winches the IP up to this level. He is then pulled in, or his lanyard cut and the IP lowered to the ground, where assistance is available. Training and practice is also vital. Hope this helps. Many people put workers in a harness, without rescue plans. Your rescue plan should not be to dial 999, by the way..........
