This topic discusses supported scaffolds. Scaffolds can be grouped in two main types: supported and suspended. Suspended platforms that together with its components weights more than 525 kg must.Suspended scaffolds that consist of more than one platform.ten metres in height above their base support if the scaffolds are constructed of a tube and clamp system.fifteen metres in height above their base support or.Scaffolds must be designed by a professional engineer in the following situations: For example, if lumber is used, it must be construction grade or Number 1 Grade spruce. Scaffolds must be constructed of suitable structural materials. A professional engineer must verify and certify the results of the test and corresponding rated load. See the topic Scaffold – Erection for more details.Įvery scaffold must be designed and constructed meet or exceed support or resist requirements and must not be loaded in excess of the load it was designed to carry. To prevent such occurrences, the constructors and employers have the responsibility to ensure that all activities related to selection, erection and dismantling of scaffolding are conducted by competent worker who have the knowledge, expertise and training required to correctly select, erect or dismantle a scaffold. Failure of scaffold or supporting system.The hazards associated with scaffolding are: Selection of the wrong type of scaffold, improper design, erection, transport, or dismantling of the structure, as well as substandard work practice may lead to serious accidents. 1926.451(a)(1) Solid sawn wood, fabricated planks, and fabricated platforms may be used as scaffold planks following the recommendations by the manufacturer or a lumber grading association or inspection agency.Scaffolds are temporary structures that consist of one or more elevated platforms used where work cannot be done on or from the ground, from a building or other permanent structure without hazard to the workers. Scaffold planking must be able to support, without failure, its own weight and at least four times the intended load. What are the requirements for scaffold planking? The space must not exceed 9.5 inches (24.1 centimeters) when side brackets or odd-shaped structures result in a wider opening between the platform and the uprights. What are scaffold platform construction requirements?Įach platform must be planked and decked as fully as possible with the space between the platform and uprights not more than 1 inch (2.5 centimeters) wide.
