Tip: Separation of frames can occur in high winds (uplift), or when workers climb endframes, overload the platform, or strike the scaffold with tools, materials, etc. Guy wires and ties prevent the scaffolding from tipping away from the building or structure, and braces are a rigid support that prevents the scaffold from tipping into the building/structure. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the supervision of a scaffold competent person.Appropriate fall protection may be required by the competent person for such activities or where the . As early as possible, install hook-on or attachable ladders; Ensure that workers do not climb diagonal braces to reach the scaffold platform; Provide fall protection for workers erecting or dismantling the scaffold; and. Therefore, employers are required to provide safe scaffold access. [, Non-mandatory examples of criteria that will enable an employer to comply with, Scaffolds are to be erected, moved, dismantled, or altered only by experienced and trained employees who have been selected for that work by the competent person. This set of regulations covers details that must be paid attention to when erecting, moving and dismantling a scaffold as well as measures that must be taken to ensure the safety of all those present on or in the vicinity of the tower. [, 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. Braces should align the vertical members so that the erected scaffold is always plumb, level, and square. The drawback to stairways, however, is the amount of space they are likely to take up in the overall structure. Scaffolds and scaffold components must be capable of supporting, without failure, their own weight and at least 4 times their maximum intended load. (Figure 13) [29 CFR 1926.451(b)(3) and 29 CFR 1926.451(b)(3)(ii)]. Changes at the worksite present a hazard for which an employee has not previously been trained. USA (v. 2008) 22 Tubular Welded-frame Scaffolds. Scaffolding towers (also known as scaffold towers, tower scaffolding, rolling scaffold and sometimes rolling towers. 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). [, A stair rail consisting of a toprail and a midrail on each side of the stairway.

Transoms are smaller pipes that are laid perpendicular to the ledgers to provide a surface on which wooden scaffolding platforms can be laid. The proper use of the scaffold, and the proper handling of materials on the scaffold. Standards are vertical pipes that are connected with clamps or couplers to give the structure its height; ledgers are horizontal braces that steady the structure and give it width. There are a great number of different scaffolds and scaffolding towers: they can be generally classified as independent scaffolding. They can decide on which material to use and also the desired dimensions. All joints must be This is one more reason for always using fall protection. Secure access to the scaffold. Check the level again and plumb if necessary. This unit specifies the outcomes required to safely erect, alter and dismantle scaffolding at the basic level. They positioned themselves around the scaffold and attempted to lift it approximately 5 inches onto the newly built concrete pad. 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. Before beginning dismantling procedures, reconstruct and/or stabilize the scaffold as necessary. [, Employees performing overhand bricklaying operations from a supported scaffold must be protected from falling from all open sides and ends of the scaffold, except at the side next to the wall being laid. 2.

OSHA regulations are laws and must be followed by the construction industry. Fall protection consists of either personal fall-arrest systems or guardrail systems, and must be provided on any scaffold 10 feet or more above a lower level. To accomplish this, the scaffold design must incorporate a realistic assessment of maximum intended loads on the scaffold at all stages of erection and loading. Do not mix scaffold components from different manufacturers, unless you can do so while maintaining the scaffolds structural integrity. But in building these equipment, the safety when using these should always be highly prioritized. Guardrails May Have Saved Him, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Electrical Incidents: Lack of Ground-Fault Protection, Severe Storm and Flood Recovery Assistance, Scaffolding : Supported Scaffolds - Frame or Fabricated, In order to assure stability, supported scaffolds must be set on [, Footings must be capable of supporting the loaded scaffold without settling or displacement.

Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. They are frequently used in one or two tiers by residential contractors, painters, etc., but their modular frames can also be stacked several stories high for use on large-scale construction jobs. Scaffolds must be fully planked or decked whenever possible. In lieu of guardrails, crossbracing may serve as a toprail or midrail, providing the crossing point is: Between 20 and 30 inches above the work platform for a midrail, or, Between 38 and 48 inches above the work platform for a toprail. Legs, posts, frames, poles, and uprights must be on base plates and mud sills, or a firm foundation and, be plum b and braced. This topic discusses supported scaffolds. To check a scaffold for being plumb, use a level on two opposite uprights. 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. 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. Top rails (manufactured after 1/1/2000) must be 38 - 45 inches above the platform surface. This will have an impact on what components you will need as well as how many of each component will be necessary to complete your tasks. (Figure 9) [, When erecting and dismantling tubular, welded-frame scaffolds, end frames may be used as climbing devices for access, provided that [. When a supported scaffold reaches a height that is more than four times its minimum base dimension (4:1), it must be restrained by guys, ties, or braces to prevent it from tipping.
