A scaffold is a temporary structure used to support workers and materials at an elevation. When using a scaffold, it’s important to consider assembly, access, inspection, electrical hazards, fall protection, special conditions, and the role of the assigned competent person.
OSHA requires that a competent person supervise scaffold erection and dismantling. This person is responsible for selecting trained or experienced workers to erect, move, or dismantle scaffolds, as well as inspecting the scaffold before each shift and after any event that could affect its structural integrity. They also have the authority to correct or eliminate any hazards or problems that occur in relation to the scaffolding.
To ensure the safety of your workers, it’s essential to start with a solid and stable footing for the scaffold. Avoid using makeshift foundations like cinder blocks, old pallets, or scrap lumber. Make sure you have all the necessary pieces (frames, braces, pins, rails, and planks) before beginning the erection process. Look out for overhead powerlines and other potential hazards like protruding rebar or falling objects. Planks must extend at least six inches beyond each end of the scaffold and be properly secured. Access ladders should be placed at the ends of the scaffold, and workers should use climbing rungs or ladders rather than climbing on the scaffold bracing. Follow the manufacturer’s instructions and safety guidelines for erecting and dismantling the scaffold.
Fall protection is also essential for scaffold safety, especially when working at heights over ten feet. In most cases, workers should wear a personal fall-arrest system like a harness and lanyard. Keep the scaffold and surrounding area clean and free of tripping hazards and falling objects. Be cautious when using mobile scaffolds, as they can be unstable on uneven surfaces or when confronted with floor openings or curbs.
