Due to their strength, these scaffolds are frequently used where heavy loads need to be carried, or where multiple platforms must reach several stories high. Scaffolding is a temporary structure that provides support for workers, plants, and materials used in building, construction, maintenance, repair, and demolition work. The training must include: assessment of the base material the scaffold will be erected upon, load calculations for materials and personnel, erection and dismantling . Top rails (manufactured after 1/1/2000) must be 38 - 45 inches above the platform surface. The momentum of the frame thrust the employee backward off the second level. [, Scaffold components manufactured by different manufacturers must not be intermixed, unless they fit together without being forced and the scaffold's structural integrity is maintained. In such cases, the platforms must be as wide as feasible, and fall protection must be provided. The focus of this position will be to construct, erect, install, and repair structures and fixtures of wood, plywood, and wallboard, using carpenter's hand tools and power tools, conforming to .

A scaffold must be erected "plumb, square, and level," because: If a scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift, potentially causing the overloading of one leg and the eventual collapse of the scaffold. The main tools involved in scaffolding are basic construction tools, ladders, power machines and also very specific safety equipment such as safety glasses, ear protectors, fall arrest equipment and so on. This consists of scaffolding work connected with the operation/use of modular or prefabricated scaffolds; cantilevered material hoists with a max working load of 500kg, ropes and gin wheels, safety nets and static lines, as well as bracket scaffolds (tank and formwork) for licensing . One exception is when the scaffold platform is within 14 inches of the face of the work. This is one more reason for always using fall protection.
