In such cases, the platforms must be as wide as feasible, and fall protection must be provided. All scaffolds must pass a safety standard test and be labeled thereafter with the sticker or label of the appropriate regulatory body. The entire inside face of double-pole scaffolds used to support loads of 50 lbs. Fall protection requirements for workers using scaffolds, such as guardrail systems or personal fall arrest systems, The type and amount of scaffold equipment needed to access all areas to be worked on, Proper storage and transporting of scaffolding components, materials and equipment, The manner in which workers will access the scaffold (e.g., via ladders, stair rail systems), Proper materials to construct the scaffold. Supported scaffold poles, legs . Most screw jacks will have a built-in stop so that the maximum height cannot be exceeded. [29 CFR 1926.451(c)(3)]. [, 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. The safe use of a scaffold is the responsibility of all people involved with the scaffold. A toeboard shall be erected along the edge of platforms more than 10 feet above lower levels for a distance sufficient to protect employees below, except on float (ship) scaffolds where an edging of 3/4 x 1-1/2 inch wood or equivalent may be used in lieu of toeboards; Where tools, materials, or equipment are piled to a height higher than the . If uplift could cause the components to separate, locking pins must be used and the components secured. Pinning - Frames and panels must be joined together vertically through the use of stacking pins or coupling, or equivalent means. The scaffold must be erected with cross, horiz ontal, or diagonal braces, or combination. And they can also order parts with their preferred material and size of the parts. missing parts due to area obstructions). 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. [, In addition to meeting the requirements of, When vertical lifelines are used, they must be fastened to a fixed safe point of anchorage, independent of the scaffold, and be protected from sharp edges and abrasion. Step 2. For example, if wrapped with mesh, will the scaffold support expected wind loads? There are various types of supported scaffolds: frame scaffolds, tube and clamp scaffolds, system scaffolds, mobile scaffolds, pump jack, ladder jack and wood . 5. 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 the side of a building) basically serves as the fall protection system. Scaffolding is naturally unstable because it is usually a tall structure with a narrow base. C. Survey the job site. In general, a level is the easiest way to achieve the desired right angles. (1) Scaffolds shall be properly braced by diagonal braces for securing vertical members together laterally, and the cross braces shall be of such length as will automatically square and align vertical members so that the erected scaffold is always plumb, square, and rigid. Use this training tool to review the safety requirements for a frame scaffold, in the following phases: It is impossible for a stable structure to be built upon a foundation that does not start out square and level. Toeboards must be capable of withstanding at least 50 pounds applied in a downward or outward direction. The frames must be plumb and level and spaced to adequately support the loads. There were no guardrails at the working level. Tube and coupler scaffold design must comply with 29 CFR 1926.451-.452. Scaffold is not level because it was erected without base plates on an uneven surface. . Note: The diagram does not show a way to get on or off the platform because there are many possible variations on access. [, Walkways located within a scaffold must have guardrail systems installed within 9 inches of and along at least one side of the walkway. Workers are most vulnerable to fall hazards when climbing on or off a scaffold. Canopy structures made of solid materials. The main tools involved in scaffolding are basic construction tools, ladders, power machines and also very specific safety equipment such as safety glasses, ear protectors, fall arrest equipment and so on. For example, if the base width is 5 feet, the first vertical tie will be (5 feet x 4) 20 feet from the ground. Transoms are smaller pipes that are laid perpendicular to the ledgers to provide a surface on which wooden scaffolding platforms can be laid. Guardrails must be installed on scaffolding over 10'. Footing. The picture above describes TRUE. Only trained and authorized persons should be allowed to use a scaffold. 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. Check the level again and plumb if necessary. Install the diagonal brace to keep the scaffolding square. 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. Has lockable wheels if it is a mobile rolling scaffold. 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. . 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. 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.

Once erected, provide toeboards on all railed sides to prevent falling object hazards. After the sign had been partially painted, the scaffold was moved to allow concrete to be placed around the sign. B. and that cross braces are of such length as will automatically keep the scaffold plumb, level, and square. (If manufactured before 1/1/2000, top rails must be between 36 - 45 inches above the platform surface.) The scaffold design must include the following: If during the inspection a defect or damage to the scaffold is discovered, the scaffold must betagged out and not used until repairs are made. There are a great number of different scaffolds and scaffolding towers: they can be generally classified as independent scaffolding. Find out more here or call us at 209-634-2929! (Figure 13) [29 CFR 1926.451(b)(3) and 29 CFR 1926.451(b)(3)(ii)]. Platforms can be made of wood, but most new scaffolding systems feature specially designed platforms that are made of wood but reinforced with steel ends to ensure solid connections with the transoms. 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. Personal fall arrest systems used on scaffolds are required when the guardrail system is incomplete or does not provide adequate protection. 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. Supported scaffold poles, legs, posts, frames, and uprights shall bear on base plates and mud sills (or other adequate firm foundation). 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.

Do not force frames or braces to fit - level the scaffold until proper fit can easily be made. [, 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. 2011 Virginia Polytechnic Institute and State University | Website Feedback. [, Not be used as work platforms when rungs are less than 11 inches in length, unless each affected employee uses appropriate fall protection. 22. (F) Tubular welded frame scaffolds. No handhold available. Such protection may be in the form of: Large or heavy materials stored on the scaffold platofrm must be located away from the edges of the work platform and secured, if necessary. 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. 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. Therefore, employers are required to provide safe scaffold access. Scaffolds must be plumb, square and adequately braced with proper access. The amount of time needed to erect and dismantle the scaffold. The correct procedures for dealing with those hazards. As they were lifting the scaffold, the top section partially separated from the adjoining section, toppled over, and contacted a power line. Also, note that the planks are bowing because the bricks are loaded at one point on the platform instead of being evenly distributed. [, 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. 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.

When platform units are abutted together to create a long platform, each abutted end must rest on a separate support surface. A tube and coupler scaffold has a platform(s) supported by tubing, and is erected with coupling devices connecting uprights, braces, bearers and runners. [, Any part of a scaffold that has been damaged or weakened so that it no longer meets OSHA strength requirements must either be repaired, replaced, braced, or removed from service. Since it is an elevated platform, the stability decreases as the height increases. While sitting or kneeling on a fixed deck plank attached to a fabricated frame scaffold, a worker was pulling a 16-foot long 2x4 off the bucket of an excavator. In addition, the scaffold and its components must support, without failure, its own weight and at least four times its maximum intended load. Requirements to prevent falls that apply only to these workers are addressed separately below. [, Guys, ties, and braces must be installed according to the scaffold manufacturer's recommendations or at the closest horizontal member to the 4:1 height ratio and be repeated every 20 vertical feet for narrow scaffolds (3 feet or less in width), and every 26 vertical feet for scaffolds greater than 3 feet in width.
