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. 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. The following procedures will cover all scaffolding erected, . 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. Platforms and walkways, in general, must be at least 18 inches wide. Hardware should be included to fasten the planks into place. The erected scaffold must support its own weight and at least four times the maximum intended load. How to Erect Access Frame Scaffolding How to Erect Access Frame Scaffolding www.worksafebc.com Select . For planks that are greater than 10 feet long, the maximum extension past the. Erects framework for structures. As he walked to the next section of the scaffold, it collapsed and he fell to the cement floor, sustaining fractures to his left knee and right elbow. [, Have minimum rung length of 11 inches. The base and mud sill must provide a solid surface for the feet to sit upon so that the scaffold doesn't sink, move, settle, or shift. Materials being hoisted onto a scaffold must In such cases, the platforms must be as wide as feasible, and fall protection must be provided. Employees involved with set up (or near) the scaffold must wear hard hats. Training shall include [. They may be made of solid material or mesh with openings no greater than 1 inch. That's one of the reasons why we need to keep it inspected - for safety sake! The amount of time needed to erect and dismantle the scaffold. Plumb and level all scaffolds as the erection proceeds. Guys, ties, and braces must be installed at locations where horizontal scaffold components support both inner and outer legs. Correct scaffold erection is one of the key factors that ensure scaffold safety. 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. If the scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift . Inadequacies in an affected employee's work indicate that the employee has not retained the necessary proficiency. We are headquartered in Turlock, CA, with locations across the heart of Californias Central Valley and beyond to provide a local feel to the solutions and services we provide our clients. 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). For example, if the base width is three feet, the first vertical tie will be (3 feet x 4) 12 feet from the ground. Faults: Damaged. Check out our special shipping rates! from the top of the sill, depending on the slope. Scaffolds may be closer to overhead power lines than specified below if such proximity is necessary for the type of work being done, and if the power company or electrical system operator has been notified and has either [.

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. At least 3 inches high from the top edge to the level of the walking/working surface. An employee was constructing the third level of a tubular, welded-frame scaffold while standing on the second level. To accomplish this, the scaffold design must incorporate a realistic 1926.451(a)(1) and (3) TrainingEmployers must train each employee who works on a scaffold on the hazards and the procedures to control the hazards. One must also consider all the necessary components and hardware needed in order to have the safest most accessible construction work platform. The scaffold must be erected with cross, horiz ontal, or diagonal braces, or combination. Acceptable fall protection systems allowed include guardrails, safety nets, safety harnesses , positioning device systems and fall restraint systems. The space between planks cannot exceed 1 inch, except where necessary for obstructions. The guardrail system shall be installed along all open sides and ends of the platform before being used as a work platform by employees. Ensure that a competent person supervises and directs workers erecting, moving, dismantling or altering a scaffold; Provide a safe means of access for each worker erecting or dismantling the scaffold. See Appendix A of Subpart L for non-mandatory toeboard guidelines. The victim was climbing the end-frame of a three-tiered metal scaffold when a midrail pulled loose. Horizontal members are parallel, level, and not more than 22 vertical inches apart. [29 CFR 1926.451(f)(5)]. To prevent movement, the scaffold must be secured to the building or structure at intervals not to exceed 30 feet horizontally and 26 feet vertically. _____ 1. Ladders that are a part of the scaffolding system, such as hook-on and attachable ladders, shall be positioned so that the bottom rung is not more than 24 inches above the supporting level. Catenary Scoffold. Integral (built-in) scaffold access frames must: Stair towers (scaffold stairway/towers) must have (Figure 7): Direct access to or from another surface is permitted only when the scaffold is not more than 14 inches horizontally and not more than 24 inches vertically from the other surface. Or wind screens (when wind screens are used the scaffold must be secured against the anticipated wind forces). Fabricated frame scaffolds are the most common type of scaffold because they are versatile, economical, and easy to use. 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. 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. Tube and coupler scaffolds over 125 feet in height must be designed by a registered professional engineer. The Scaffold cross braces should never be used as a means of access. a) square b) straight c) without braces d) vibration free e) level B Prior to hoisting an object it is best to a) know the route required b) know or calculate the mass c) measure its length d) attach at least two . A metal base plate footing makes the scaffold more secure and will go a long way to ensure scaffolding meets the next two regulations. . 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. . Not tied. In general, a level is the easiest way to achieve the desired right angles. Secure scaffolds to the structure during erection and dismantling. 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. Fasten the levelling jack to the sills with either nails or screws. One exception is when the scaffold platform is within 14 inches of the face of the 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 . [, Scaffolds and scaffold components must be inspected for visible defects before each shift by a competent person, and after each occurrence that could affect a scaffold's integrity (such as being struck by a crane). Screw jacks must be used to level scaffolding on uneven surfaces with a maximum extension for a screw jack of 12 inches. We commit to utilizing our collective talent to support your risk management and insurance goals. [, OSHA standards specifically forbid climbing cross-braces as a means of access.

Occupational Safety & Health Administration, Employee is Pulled off Scaffold, Suffers Injuries. Don't use bricks, blocks, barrels, or other unstable objects to level a scaffold. The main components are scaffolding tubes, scaffold clamps, and base plates. 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. Requirements to prevent falls that apply only to these workers are addressed separately below. 22.B.12 Scaffolds shall be plumb and level unless engineered and designed to contour as the structure does. In addition, the scaffold and its components must support, without failure, its own weight and at least four times its maximum intended load. Tube and coupler scaffold design must comply with 29 CFR 1926.451-.452. Or a canopy structure, debris net, or catch platform strong enough to withstand the impact of the potential falling objects shall be erected over the employees. Because the frames are stacked, the cross braces have to keep the scaffold plumb, level, and square. 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. 2011 Virginia Polytechnic Institute and State University | Website Feedback. The maximum intended load and the load-carrying capacity of the scaffold. 6. e. Tip: One way to ensure a stable foundation, when a sill is used, is to secure it to the baseplate (Figure 2). [29 CFR 1926.451(e)(9)(i)]. must be plumb and braced to prevent swaying and displacement. [, Ends of rails may not extend beyond their terminal posts, unless they do not constitute a projection hazard to employees. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. Scaffolds must not be close enough to overhead power lines that they, or any conductive materials (e.g. Therefore, an inspection of a scaffold platform requires safety checks of both the platform structure and how the platform is used by the workers. . Tube and coupler scaffold design must comply with 29 CFR 1926.451-.452. Some people would like their own customized scaffold towers. 1. 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. For most activities, there must be no more than a 14-inch gap between the scaffold platform and the structure being worked on. The wood must be clear, free of loose knots, splits, or other defects. The nature of any electrical hazards, fall hazards, and falling object hazards in the work area. building materials, paint roller extensions, scaffold components) that may be handled on them, come closer than 10 feet to the power line.

(k) The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. The employer must provide suitable access to and between scaffolds, such as portable ladders, hook-on ladders, attachable ladders and stairway-type ladders. When platform units are abutted together to create a long platform, each abutted end must rest on a separate support surface. Scaffolding means a convenient platform for persons to work at height. Warped. Erectors and dismantlers face additional access problems due to the incomplete condition of the scaffolding. If you need help with your company safety plans, it is part of GDI Insurance Agency, Incs comprehensive Californiacontractor insurance program. 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. At Virginia Tech, a fall protection system (i.e. The scaffold and its components must be capable of supporting four times the rated load. 5. [, Be used only to support personnel, unless the scaffold has been designed for other loads by a qualified engineer and built to withstand the tipping forces caused by other loads. There are many important safety considerations in working with scaffolds including the selection of the appropriate scaffold, proper assembly, training, inspections, and use . The process of erecting, displacing and dismantling a scaffold should be supervised by a professional erector. [. Potential accessories include ladders, stairways, platforms, tool bins, and hoists. Scaffold tower can be erected in all shapes and sizes. The jack-nut at the highest ground level should be set 7.5-15 cm (3-6 in.) 2. 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. [, 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. They can also choose if they want it mobile or stationary. You will need many of each component for larger structures. B.13 Scaffolds (other than suspended scaffolds) shall bear on . Stability and durability are the key components for the scaffold towers to be safe. Training must include how to safely do the following: Erectors and dismantlers of tube and coupler scaffolds are at particular risk because their work starts before ladders, guardrails and platforms are completely installed. [, Fall protection consists of either personal fall arrest systems or guardrail systems meeting OSHA requirements. [, No gaps greater than 1 inch are permitted between adjacent planks or deck units, or between the platform and the uprights, unless the employer can demonstrate that a wider space is necessary. When the employee tried to set the third level frame into the pins of the second level, the frame he was trying to position flipped to one side. Light-duty scaffolds can support 25 pounds per square foot. Place the planks. TRUE represents being SQUARE on both the LEVEL & PLUMB axis at the same time on all sides of the unit being installed. Plumb and level all scaffolds as the erection proceeds. Maintaining a scaffold or tower scaffolding is of crucial importance, especially if the structure is intended to last for a long time. [, 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. The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. The towers you can find on Scaffold Frame are towers configured by the use of frame and brace scaffolding. This training must be provided by a qualified person who understands the hazards associated with the type of scaffold being used and who knows the procedures to control or minimize those hazards. The two measurements should be equal. Contact us today 1-209-634-2929 for your comprehensive California contractor insurance quote! [, 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. Greater variations in riser height are allowed for the top and bottom steps of the entire system (not for each flight of stairs). [, Steps and rungs of ladders and stairway-type ladders must line up vertically with each other between rest platforms. Midrails must be capable of supporting at least 150 pounds applied in a downward or outward direction. [, Scaffold platforms and walkways must be at least 18 inches wide, unless they are used in areas that the employer can demonstrate are so narrow that they must be less than 18 inches wide. Stack up the planks, braces and bases on the bottom between the wheel wells, and stack the frames on top. A checklist of items a competent person should complete daily for scaffold safety. Tip: A level may be used frequently during assembly to guarantee that new structural components remain in line. Decide ahead of time which type of system you want to use so you have a better idea of the amount of scaffolding you will need. [, When midrails are used, they must be installed at a height approximately midway between the top edge of the guardrail system and the platform surface. These scaffolds can be assembled in multiple directions, making them the preferred option for work surfaces with irregular dimensions and/or contours. . Supported scaffold poles, frames, uprights, etc. Safe points of anchorage include structural members of buildings, but not standpipes, vents, electrical conduit, etc., which may give way under the force of a fall. He fell, sustaining a concussion for which he was hospitalized. Haul Scaffolding Safely. Only two workers may be on a pumpjack scaffold at a time. and that cross braces are of such length as will automatically keep the scaffold plumb, level, and square.
