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. bucks) must be joined together vertically by coupling or stacking pins (or equivalent means). If uplift could cause the components to separate, locking pins must be used and the components secured. Is secured to prevent lateral movement. Toeboards must be capable of withstanding at least 50 pounds applied in a downward or outward direction. Consider such platforms for added stability and safety. B. As one of the fastest growing agencies in California, GDI Insurance Agency, Inc. is able to provide its clients with the latest and greatest of what the insurance industry has to offer and much, much more. [, 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. See Appendix A of Subpart L for non-mandatory toeboard guidelines. 3. Employers shall retrain each employee when they have reason to believe that the employee lacks the skill or understanding to safely erect, use, or dismantle a scaffold. (Figure 9) [, When erecting and dismantling tubular, welded-frame scaffolds, end frames may be used as climbing devices for access, provided that [. All diagonal . If the scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift . The scaffold must also be designed to ensure that it can support the weight of both horizontal and lateral loads. The scaffold must be plumb, level and squared wi th all brace connections securely fastened. At Virginia Tech, a fall protection system (i.e. An access ladder or equivalent safe access must be provided. Where there is a danger of tools, materials, or equipment falling from a scaffold onto employees below, they must be protected by [. The top edge height of toprails on supported scaffolds must be between 36 inches and 45 inches. Personal fall protection must be required and provided by the employer where the installation and use of such protection is feasible and does not create a greater hazard. 6. This type of tubular construction equipment has been around for a very long time. 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. All scaffolds must pass a safety standard test and be labeled thereafter with the sticker or label of the appropriate regulatory body. Where a platform changes direction (ex. Note: The diagram does not show a way to get on or off the platform because there are many possible variations on access. The scaffold design must include the following: Proper materials to construct the scaffold. 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 Suspension scaffold rigging must at least 6 times the intended load. Has a platform that is at least 500mm wide. An employee was constructing the third level of a tubular, welded-frame scaffold while standing on the second level. [, Ties, guys, braces, or outriggers shall be used to prevent tipping of supported scaffolds bearing eccentric loads, such as cantilevered work platforms. The other five workers were hospitalized with electrical burns. These are only a few basic physical structures of scaffold towers. Personal Fall Arrest System. Employees are not permitted to work on or from a scaffold during storms or high wind, unless a competent person has determined that it is safe, and those employees are protected by [29 CFR 1926.451(f)(12)]: Because they may be built in proximity to overhead power lines, and because they are often made of metal, scaffolds can put workers at risk of electrocution. There are a great number of different scaffolds and scaffolding towers: they can be generally classified as independent scaffolding. Only two workers may be on a pumpjack scaffold at a time. Scaffolding means a convenient platform for persons to work at height. Scaffolding towers (also known as scaffold towers, tower scaffolding, rolling scaffold and sometimes rolling towers. This topic discusses supported scaffolds. [, Be positioned so that their bottom step is not more than 24 inches above the scaffold supporting level, [, Have rest platforms at maximum vertical intervals of 12 feet, [, Have a minimum step width of 16 inches, except for mobile scaffold stairway-type ladders, which shall have a minimum step width of 11 inches [, Have slip-resistant treads on all steps and landings. 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. Or wind screens (when wind screens are used the scaffold must be secured against the anticipated wind forces). Point loading, or concentrating too much of the load in one area. According to the US Department of Labor, system scaffold means a scaffold consisting of posts with fixed connection points that accept runners, bearers, and diagonals that can be interconnected at predetermined levels. [, As frames are stacked, cross braces must be of such length as will automatically keep the scaffold plumb, level, and square. Not tied. They can also choose if they want it mobile or stationary. Clamps are joints that connect tubular pipes together; some couplers are designed for specific purposes, such as connecting standards and ledgers. Basically this is referring to a stand alone structure with platform. Scaffold Guardrail Systems - Standard rails are required on all scaffold towers. Screw jacks must be used to level scaffolding on uneven surfaces. [, A distance of no less than 28 inches and no more than 37 inches from the upper surface of the stair rail to the forward edge of the tread, in line with the face of the riser. [, Uniform riser height, within -inch, for each flight of stairs. The hazards of type of scaffold being used. Ladder Jack Scaffold. [29 CFR 1926.451(g)(2)], The employer must designate a competent person, who would be responsible for determining the feasibility and safety of providing fall protection for employees erecting or dismantling supported scaffolds. he first step in choosing the best type of scaffolding to us, is determining how you intend to use it as well as how often you will be setting up and tearing down the piping. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. Construction and loading must comply with engineered designs and manufacturers requirements. the diagonal brace to keep the scaffolding square. Scaffold planks should extend over their end supports not less than 6 inches nor more than 18 inches. e. Cross-bracing is required on both front and back sides of each scaffold buck or frame. It's best to have everything as low as possible so parts don't get blown or bounced out. Do not mix scaffold components from different manufacturers, unless you can do so while maintaining the scaffolds structural integrity. the side of a building) basically serves as the fall protection system. and must be provided on any scaffold 10 feet or more above a lower level. Scaffold components of dissimilar metals should not be used together, unless the competent person has determined that galvanic action will not reduce the strength of any component. The scaffold should be plumb, level and square. Barricades to keep personnel out of a hazardous area. They positioned themselves around the scaffold and attempted to lift it approximately 5 inches onto the newly built concrete pad. Position the first level of bracing as close to the base as possible. In general, a level is the easiest way to achieve the desired right angles. 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 . [, Scaffold components manufactured by different manufacturers are not allowed to be modified to make them fit together, unless a competent person determines that the resulting scaffold is structurally sound. Tip: A level may be used frequently during assembly to guarantee that new structural components remain in line. 3. When the other end of the 2x4 slipped off the bucket, the employee did not let go of his end, and was pulled off the deck. (Your Answer) 3. Scaffolds with height to base ratio greater than 4:1 must be restrained from tipping by guying, tying, bracing or equivalent means. He fell approximately 12 feet to a concrete dock. This poses a risk of electrocution not just to the worker holding the tool, but to everyone who contacts the scaffold. [29 CFR 1926.451(g)(2)]. It is not all-inclusive and should be used as a starting point for the competent person to develop a checklist specific to the type of scaffold and jobsite conditions encountered. (Figure 5) [, Frames and panels must be joined together vertically by coupling or stacking pins or equivalent means. [, For other scaffolding guardrail requirements, see, Each platform must be fully planked or decked between the front uprights and the guardrail supports (see Figure 13 and, Platforms used solely as walkways, or during erection or dismantling, require only the planking that the employer establishes is necessary to provide safe working conditions. Damaged or deteriorated equipment must not be used USA (v. 2008) 21 Erecting Scaffolding. 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. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the supervision of a scaffold competent person. We need to follow scaffolding safety procedures. These scaffolds can be assembled in multiple directions, making them the preferred option for work surfaces with irregular dimensions and/or contours. Crossbracing is required on both front and back sides of each scaffold buck or frame. Install guys, ties and braces according to the manufacturers recommendations. [, When platforms must overlap because a scaffold changes direction, such as turning a corner, platforms that rest on a bearer at an angle other than a right angle shall be laid first, and platforms that rest at right angles over the same bearer shall be laid second, on top of the first platform. Always use . 1. 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. Additional protection from falling debris and other small objects must be provided in areas where personnel will be in the vicinity of scaffolds. The correct procedures for dealing with those hazards. Proper access must be provided to access the work platform of the scaffold. [, Guardrail systems must be installed along all open sides and ends of platforms, and must be in place before the scaffold is released for use by employees other than erection/dismantling crews.
