Take precautions while welding.









You must do the following to protect employees while welding on suspended scaffolds: (1) Use an insulated thimble to attach each suspension wire rope to its hanging support, such as a cornice hook or outrigger; (2) Insulate excess suspension wire rope and any additional independent lines to prevent grounding; (3) Cover the wire suspension rope with insulating material that extends at least four feet (1.2 m) above the hoist; (4) Make sure any tail line that extends below the hoist is: (a) Insulated to prevent contact with the platform; and (b) Guided or retained so it does not become grounded. (5) Cover each hoist with an insulated protective cover; (6) Connect the scaffold to the structure using a grounding conductor that: (a) Is at least the size of the welding process work lead; and (b) Is not in series with the welding process or the work piece. (7) Shut off the welding machine if the scaffold grounding lead becomes disconnected; (8) Make sure an active welding rod or an uninsulated welding lead is not allowed to contact the: (a) Scaffold; or (b) Scaffold suspension system.
