Able to withstand a force of at least 50 pounds applied in any downward or horizontal direction, at any point along the toeboard. Also they can be mobile or stationary. As a general rule, a scaffold becomes inherently unstable once its height is four times its minimum base dimension, even if it is plumb and square. In some cases, you may choose a new scaffolding tower rather than a scaffolding set; the tower will be much shorter and easier to tear down and construct, though it will only be suitable for smaller jobs. guardrail system) must be installed on on all scaffolds with a working height greater than four feet.

Tube and coupler scaffold design must comply with 29 CFR 1926.451-.452. Tip: Because it may be difficult to determine if a power line is insulated, or what its exact voltage is, the 10 foot rule should always be applied. Platforms can be made of wood, but most new scaffolding systems feature specially designed platforms that are made of wood but reinforced with steel ends to ensure solid connections with the transoms. Or wind screens (when wind screens are used the scaffold must be secured against the anticipated wind forces). When conditions warrant, the height of the top edge may exceed the 45-inch height, provided the guardrail system meets all other criteria. Personal Fall Arrest System. Such a scaffold can be set up on either side of the building, and offers a great level of flexibility. If uplift could cause the components to separate, locking pins must be used and the components secured. Planking on this platform should be six planks wide, instead of only two.

[, Do not load the scaffold or any component parts beyond their maximum capacity (their own weight and 4:1 the maximum intended load). Learn how your comment data is processed. Therefore, an inspection of a scaffold platform requires safety checks of both the platform structure and how the platform is used by the workers. If the scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift .

Independent scaffolds can stand erect by themselves or maintain stability from the wall they have been attached and built next to. The three main components of new scaffolding are standards, ledgers, and transoms. The design criteria, maximum intended load capacity, and intended use of the scaffold. Where platforms overlap to create a running scaffold, the overlap must occur only over a support and shall not be less than 12 inches unless nailed together. The distance between beare r s and runners shall not exceed manufacturer's re c o m-m e n d a t i o n s .

[, A scaffold stairway width of at least 18 inches between stair rails. To be specific, a "true" surface is as "plumb" or as "level" as the job requires (which, in most cases, is a perfect level of both or either). Cross-bracing is required on both front and back sides of each scaffold buck or frame. The height of the scaffold in relation to the minimum base width, wind loads, the use of brackets or cantilevered platforms, and [, Employers are required to provide safe access for employees erecting or dismantling supported scaffolds where it is feasible, and where it does not create a greater hazard. Scaffolding is naturally unstable because it is usually a tall structure with a narrow base. Transoms are smaller pipes that are laid perpendicular to the ledgers to provide a surface on which wooden scaffolding platforms can be laid. [, On scaffolds where platforms are overlapped to create a long platform, the overlap may only occur over supports, and may not be less than 12 inches, unless the platforms are restrained (i.e., nailed together) to prevent movement. The maximum extension of the plank cannot be more than 12 inches for planks that are 10 feet long or less. Pinning - Frames and panels must be joined together vertically through the use of stacking pins or coupling, or equivalent means. Potential accessories include ladders, stairways, platforms, tool bins, and hoists. Personal fall arrest systems used on scaffolds are required when the guardrail system is incomplete or does not provide adequate protection. (l) Use a tag line when hoisting materials onto a scaffold. NOTE: Except where indicated, these requirements also apply to manually propelled, pump jack, ladder jack, tube and coupler, and pole scaffolds as well as the specialty scaffolds described in the Supported Scaffolds module. The planking used must be "scaffold grade.". Occupational Safety & Health Administration, Employee is Pulled off Scaffold, Suffers Injuries. If using wooden planks, they must extend beyond the supporting points Employers must provide fall protection for each employee on a scaffold more than 10 feet (3.1 meters) above a lower level. Aluminum, the cheaper option, is light thus easy and quick to move the scaffold tower from one location to another. Midrails must be installed at a height approximately midway between the toprail and the platform surface. Because the frames are stacked, the cross braces have to keep the scaffold plumb, level, and square. For example, if the base width is three feet, the first vertical tie will be (3 feet x 4) 12 feet from the ground. In Asia, bamboo is used as a construction material. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. Before beginning dismantling procedures, reconstruct and/or stabilize the scaffold as necessary. Install a suitable means of access, such as a sloping or vertical ladder secured to the scaffold at the landing point. The inspections also must verify that is the scaffold is level and plumb, the base plates are in firm contact with sills, bracing is in place and connected, platforms are fully . Use footings that are level, sound, rigid and capable of supporting the load without settlement or displacement. Be sure scaffold stays plumb and level as erection progresses. Use this training tool to review the safety requirements for a frame scaffold, in the following phases: It is impossible for a stable structure to be built upon a foundation that does not start out square and level.
