The height of the scaffold in relation to the minimum base width, wind loads, the use of brackets or cantilevered platforms, and These are only a few basic physical structures of scaffold towers. Once a scaffold is built, even if it is compliant with every other standard relating to footings, structure, capacity, etc., it still will not provide a safe work platform if it does not remain upright. Avoid propping the scaffolding frames up on the side of the bed. Place the planks. Safe points of anchorage include structural members of buildings, but not standpipes, vents, electrical conduit, etc., which may give way under the force of a fall.
