"Footings shall be level, sound, rigid, and capable of supporting the loaded scaffold without settling or displacement." 1926.451 (c) (2) (i) Although not an issue in this photo, this means that if the . The nature of any electrical hazards, fall hazards, and falling object hazards in the work area. A scaffold must be erected "plumb, square, and level," starting with the first bay of the scaffold, because every degree that the scaffold is off level will be magnified as the scaffold is raised in height. [, Employees must be able to safely access any level of a scaffold that is 2 feet above or below an access point. Construction and loading must comply with engineered designs and manufacturers requirements. Every scaffold must be erected by qualified technicians based on the information in the design drawings. Workers building scaffolds risk serious injury from falls and tip-overs, being struck by falling tools and other hazards and electrocution from energized power lines. The amount of time needed to erect and dismantle the scaffold. All brace connections shall be made secure. Cross-bracing is required on both front and back sides of each scaffold buck or frame. Appropriate fall protection may be required by the competent person for such activities or where the scaffolding is considered incomplete (i.e. Reaching 5 foot high all the way up to 30 feet tall. Some people would like their own customized scaffold towers. Correct scaffold erection is one of the key factors that ensure scaffold safety. [29 CFR 1926.451(e)(9)(i)].

Make sure that a competent person inspects the scaffold before each work shift. [, When horizontal lifelines are used, they are to be secured to two or more structural members of the scaffold. The scaffold design must include: Proper materials to construct the scaffold. 1. The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. Where the platform will not be more than 14 inches from the face of the work (18 inches for plastering and lathing operations), fall protection is not required. 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. By far, the most forgotten term of a door installation. [, 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. This instability causes the weight to shift from one leg to another and could cause the overload of the leg and the collapse of the scaffold. decking, planks) must not be painted to hide defects. 3. 6. [29 CFR 1926.451(c)(3)]. Tip: A scaffold can be overloaded by removing the braces, which causes the weight on the scaffold to be distributed to fewer structural members. No handhold available. Scaffolds are generally rated as light, medium or heavy duty and must be able to support the correlating weight of workers and materials required for each type. To counteract this, the scaffold must be braced or tied off to a stable structure such as a structural steel. Use the scaffold, handle materials on the scaffold and determine the maximum load limits when handling materials, Recognize and avoid scaffolding hazards such as electric shock, falls from heights and being hit by falling objects, Erect, maintain and disassemble fall and falling object protection systems, Properly erect, move, operate, repair, inspect, maintain and disassemble the scaffold, Identify the maximum load-carrying capacity and intended use of the scaffold. Lanyards or connecting devices must be connected to a vertical lifeline (1st choice), a horizontal lifeline (2nd choice), or a structural member of the scaffold (last choice). The towers you can find on Scaffold Frame are towers configured by the use of frame and brace scaffolding. The height of the scaffold in relation to the minimum base width, wind loads, the use of brackets or cantilevered platforms, and 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. The ends of each platform must be cleated or restrained by hooks (or equivalent) to prevent accidental displacement, or must extend at least 6 inches over the centerline of the support. Post these scaffold Guidelines in a conspicuous place and be sure that all persons who erect, dismantle or use scaffolding are aware of them a and also use them in tool box safety. Posts shall be erected plumb in all directions, with the first level of runners and bearers positioned as close to the base as feasible. Because the number of injuries from . Personal Fall Arrest System, Guardrail System, or 3/4 inch (1.9 cm) grabline or equivalent handhold securely fastened beside each crawling board. Frames and panels should also be locked together to prevent uplift. Attach tags at the access point of the scaffold. Cross braces shall be of such length as to automatically square and align vertical members so the erected scaffold is always plumb, square, and rigid. Scaffolds must be fully planked or decked whenever possible. (k) The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. Supported scaffold poles, frames and uprights must be plumb and braced to prevent any displacement caused by swaying. [, It is dangerous and therefore impermissible for two or more vertical lifelines to be attached to each other, or to the same point of anchorage. Light-duty scaffolds can support 25 pounds per square foot. Use footings that are level, sound, rigid and capable of supporting the load without settlement or displacement. Fasten all couplers and/or connections securely before assembling the next level. This would be in reference to stand alone scaffold towers. [, Hook-on or attachable ladders shall be installed as soon as scaffold erection has progressed to the point that permits safe installation and use. He suffered multiple fractures to the head, left and right foot, and left wrist, and torn ligaments in the knees. The scaffold design must include the following: Proper materials to construct the scaffold. Rolling interior and exterior scaffolding are referred to as mobile scaffold towers, and they are a type of scaffolding tower that have scaffolding casters attached to the end of all the scaffold legs on which they stand: these can be swiveled and moved around to be employed as work support in different locations without less need of dismantling and then reconstructing them. [29 CFR 1926.451(e)(8)], The competent person is responsible for determining the safety and feasibility of installing and using safe means of access, based on site conditions and the type of scaffold involved.

OSHA 1926.454 (c) states: When an employer has reason to believe . [, Ties, guys, braces, or outriggers shall be used to prevent tipping of supported scaffolds bearing eccentric loads, such as cantilevered work platforms. [. Once erected, provide toeboards on all railed sides to prevent falling object hazards. Midrails must be installed at a height approximately midway between the toprail and the platform surface. [, Fall protection consists of either personal fall arrest systems or guardrail systems meeting OSHA requirements. Critical to scaffolding safety are the use of competent persons for the design, erection/dismantling, and maintenance of scaffolds, and trained workers for their use. [, Sufficient handhold on handrails, and toprails serving as handrails, for employees grasping them to avoid falling. And frames that stick out past the side of the bed can be . 4. An employee was constructing the third level of a tubular, welded-frame scaffold while standing on the second level. Faults: Damaged. The cross braces shall be of such length as will automatically square and align vertical members so that the erected scaffold is always plumb, level, and square.
