Follow all state, local and federal codes, ordinance and regulations pertaining to scaffolding. Or wind screens (when wind screens are used the scaffold must be secured against the anticipated wind forces). 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. Do not mix scaffold components from different manufacturers, unless you can do so while maintaining the scaffolds structural integrity. The amount of time needed to erect and dismantle the scaffold. Chicken Ladder. This will determine how many of each component you will need. [, 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. The frames must be plumb and level and spaced to adequately support the loads. [29 CFR 1926.451(f)(5)]. Erects framework for structures. [, Have uniform spacing between rungs of a maximum 16 inches. And frames that stick out past the side of the bed can be . Changes at the worksite present a hazard for which an employee has not previously been trained. In general, a level is the easiest way to achieve the desired right angles. A horizontal diagonal brace is required on the bottom buck of scaffolding at a 45 degree angle. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the direct supervision of a scaffold competent person. Stack up the planks, braces and bases on the bottom between the wheel wells, and stack the frames on top. 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. Review blueprints, work orders, the project schedule and other written requirements to determine where these scaffolds should be used. If using wooden planks, they must extend beyond the supporting Personal Fall Arrest System, Guardrail System, or 3/4 inch (1.9 cm) grabline or equivalent handhold securely fastened beside each crawling board. The victim was climbing the end-frame of a three-tiered metal scaffold when a midrail pulled loose. Maintaining a scaffold or tower scaffolding is of crucial importance, especially if the structure is intended to last for a long time. PLUMB/LEVEL/SQUARE. All brace connections shall be made secure. As they were lifting the scaffold, the top section partially separated from the adjoining section, toppled over, and contacted a power line. Uplift is the separation of a frame from the frame below it. Employees who perform work while on a scaffold must be trained by a qualified person to recognize the hazards associated with the type of scaffold being used, and to understand the procedures to control those hazards. Haul Scaffolding Safely. Scaffolds must not be close enough to overhead power lines that they, or any conductive materials (e.g. Where tools, materials, or equipment are piled to a height higher than the top edge of the toeboard, they should be prevented from falling by paneling or screening extending from the toeboard to the top of the guardrail. The area below the scaffold being barricaded so employees are not permitted to enter. They may, however, be treated periodically with clear preservatives, fire-retardants, and/or slip-resistant finishes. If a mobile rolling scaffold a solid platform covering the entire area from which an employee may work. It is strong, dependable, and is relatively low in cost. The guardrail system shall be installed along all open sides and ends of the platform before being used as a work platform by employees.

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 scaffolding is considered incomplete (i.e. The proper use of the scaffold, and the proper handling of materials on the scaffold. A scaffold must be erected "plumb, square, and level," because: - Ans-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. The objective is to reduce the tripping hazard by having the ends of the top layer of planks form a straight line, rather than a saw-toothed edge, which increases tripping hazards. Secure access to the scaffold. Planking on this platform should be six planks wide, instead of only two. Frames and panels shall be braced by cross, horizontal, or diagonal braces, or combination thereof, which secure vertical members together laterally. (F) Tubular welded frame scaffolds. [, 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. Vertical means up and down. Placement of potential falling objects away from the edge of the surface from which they may fall when the falling objects are too large, heavy or massive to be contained or deflected by any of the above-listed measures. [, 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. (Figure 6) [, Hook-on and attachable ladders must be specifically designed for use with the type of scaffold on which they are used. Scaffold components cannot be mixed if they are from different manufacturers unless they fit together without force. [, OSHA standards specifically forbid climbing cross-braces as a means of access. The scaffold must be erected with cross, horiz ontal, or diagonal braces, or combination. Note: Except where . [, Wooden planking must not be covered with opaque finishes, except that platform edges may be marked for identification. Platforms may be coated periodically with wood preservatives, fire retardants, and slip-resistant finishes, provided they do not obscure the top or bottom wood surfaces. Once erected, provide toeboards on all railed sides to prevent falling object hazards. Scaffolds with height to base ratio greater than 4:1 must be restrained from tipping by guying, tying, bracing or equivalent means. [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. Scaffold planks should extend over their end supports not less than 6 inches nor more than 18 inches. Be sure scaffold stays plumb and level as . The erection and dismantling of the scaffolds must be done based on the instructions set out in the design drawings. 6. 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. Secure scaffolds to the structure during erection and dismantling. A specific access, such as a mounted ladder, must be used. Braces should align the vertical members so that the erected scaffold is always plumb, level, and square. Scaffolds with a height-to-base width ratio of more than four to one shall be restrained from tipping over by guying, tying, bracing, or equivalent means. B. Cross braces must keep the scaffold plumb, level, and square; All brace connections must be secured to prevent dislodging; Frames and panels must be joined together vertically by coupling or stacking pins or equivalent means; Frames and panels must be locked together to prevent uplift (separation of a missing parts due to area obstructions). 2. [, As frames are stacked, cross braces must be of such length as will automatically keep the scaffold plumb, level, and square. Stability and durability are the key components for the scaffold towers to be safe. Toeboards must be installed not more than 1/4 inch above the platform and securely fastened. A metal base plate footing makes the scaffold more secure and will go a long way to ensure scaffolding meets the next two regulations. Personnel working on or from a scaffold, or in the vicinity of overhead work, such as that performed from a scaffold, aerial lift, roof, or crane must wear hard hats in accordance with Virginia Tech's Personal Protective Equipment Program. [29 CFR 1926.451(e)(9)(i)]. Be supported by bearing blocks securely attached to the poles. [, Uniform tread depth, within -inch, for each flight of stairs. Not tied. Workers are most vulnerable to fall hazards when climbing on or off a scaffold. Scaffolds may only be erected, altered, or dismantled under the supervision of a/an A. 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. OSHA 1926.454 (c) states: When an employer has reason to believe . 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. Because the frames are stacked, the cross braces have to keep the scaffold plumb, level, and square. Proper access must be provided to access the work platform of the scaffold. (k) The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. To ensure the scaffold is "square", use a tape measure and measure the distance between opposite corners. Metal pumpjack scaffolds cannot be more than 13.7 m in height; and must be braced every 4.6 m. Pumpjack scaffolds with supports made of wood must not be more than 7.3 m in height and must be braced every 3 m. Without a subpoena, voluntary compliance on the part of your Internet Service Provider, or additional records from a third party, information stored or retrieved for this purpose alone cannot usually be used to identify you.

This individual must supervise all scaffold assemblies, changes, movement, or dismantling. At Virginia Tech, a fall protection system (i.e. 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. 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. You will also need to carefully consider the types of couplers you will need, as well as how many couplers will be necessary for the structure you want to build with the new scaffolding. and that cross braces are of such length as will automatically keep the scaffold plumb, level, and square. For long (running) scaffolds, guys, ties, and braces shall be installed at each end of the scaffold and at horizontal intervals not to exceed 30 feet. 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. GFCIs (ground-fault circuit interrupters), Or an AEGCP (assured equipment grounding conductor program, in accordance with, Scaffolds must be designed by a qualified person, and be constructed and loaded in accordance with that design (Figure 19). 3. . the diagonal brace to keep the scaffolding square. Reaching 5 foot high all the way up to 30 feet tall. Crossbracing is required on both front and back sides of each scaffold buck or frame. Barricades to keep personnel out of a hazardous area.

The ladder must extend 1 m (3 ft.) above the landing. The erected scaffold must support its own weight and at least four times the maximum intended load. Runners and bearers must be installed on edge. Specific requirements are described below. decking, planks) must not be painted to hide defects. That's one of the reasons why we need to keep it inspected - for safety sake! [29 CFR 1926.451(c)(3)]. 5. Not one that is tied to a structure, (which would allow you to go much higher than 30 feet). Do not force frames or braces to fit - level the scaffold until proper fit can easily be made. Unsafe scaffolding has the potential to result in death or serious . A checklist of items a competent person should complete daily for scaffold safety. For lathing and plastering, a gap of 18 inches is permitted. Guardrails must be installed on scaffolding over 10'. [, When moving platforms to the next level, the existing platform must be left undisturbed until the new end frames have been set in place and braced. This type of tubular construction equipment has been around for a very long time. For example, if the base width is three feet, the first vertical tie will be (3 feet x 4) 12 feet from the ground. The competent person should use this checklist for daily inspections of the scaffold. [, 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). USA (v. 2008) 22 Tubular Welded-frame Scaffolds. The scaffold should be plumb, level and square. There are two kinds of falling object hazards associated with scaffolds. Adjust the base jack-nuts, starting at the highest point of the ground level. The technical storage or access that is used exclusively for statistical purposes.
