Scaffolds are temporary structures used extensively in construction work to provide safe access and working platforms at height. Since scaffold failure or improper use can result in falls, falling objects, structural collapse and serious injuries, their erection, inspection, use and dismantling must be carried out according to proper safety procedures. The scaffold should be designed according to the intended load, height, type of work, site conditions and applicable safety regulations. Before erection, the site should be carefully assessed. The ground or supporting surface must be firm, level and capable of supporting the expected load of the scaffold, workers, materials and equipment. Loose soil, excavated areas, waterlogged ground and unstable surfaces should be properly treated before erection. The area should be cleared of unnecessary materials and protected from vehicular or other site traffic. Underground services and overhead electrical lines should also be identified so that the scaffold does not come into contact with them. Only sound and suitable materials should be used for scaffold construction. Tubes, couplers, frames, boards, platforms, ladders and other components must be free from cracks, excessive corrosion, bends, defects or other damage. Defective components must be removed from service. The scaffold should be erected by trained and competent workers under the supervision of a qualified person. Workers involved in erection should use appropriate personal protective equipment such as safety helmets, safety footwear, gloves and suitable fall-protection equipment. The scaffold must be
