Erects framework for structures. (Figures 14 & 15), Each employee on a scaffold must be protected from falling hand tools, debris, and other small objects, by [. All brace connections must be secured to prevent dislodging. Scaffolding. [, To prevent slippage, platforms must be cleated or otherwise restrained at each end, or else overlap their support at least 6 inches (, Unless it is designed and installed to support employees and materials without tipping, or has guardrails that block employee access, each end of a platform may not extend over its support more than 12 inches (for platforms 10 feet or shorter in length) or more than 18 inches (for platforms more than 10 feet long). [, 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. [, 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. [, Scaffold platforms must be able to support their own weight, plus four times the maximum intended load. [, Ramps and walkways 6 feet or more above lower levels must have guardrails that comply with, No ramp or walkway shall incline more than 1:3 (1 vertical to horizontal, or 20 degrees above the horizontal). The top edge height of toprails on supported scaffolds must be between 36 inches and 45 inches. Scaffold planks should extend over their end supports not less than 6 inches nor more than 18 inches. Not tied. (j) Scaffold planks must extend over their end supports not less than 6 inches nor more than 18 inches. The working surface was solidly planked. 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. (l) Use a tag line when hoisting materials onto a scaffold. [, 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. Attach tags at the access point of the scaffold. Such retraining is required in at least the following situations [. Uplift is the separation of a frame from the frame below it. This would be in reference to stand alone scaffold towers. [, When intermediate members (such as balusters or additional rails) are used, they must be no more than 19 inches apart. [, 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. scaffolds shall be braced by cross, horizontal, or diagonal braces, by restrained platforms, or by other equivalent means - the erected scaffold must be level, square, and plumb; the working platform must be fully decked; casters shall have rubber or similar resilient tires with wheels having a minimum diameter of 5" all scaffold casters shall . Install the diagonal brace to keep the scaffolding square. [, Guardrails must be surfaced to prevent punctures or lacerations to employees and to prevent snagging of clothing, which may cause employees to lose their balance. bucks) must be joined together vertically by coupling or stacking pins (or equivalent means). Point loading, or concentrating too much of the load in one area. If using wooden planks, they must extend beyond the supporting points Ladders are used to provide access to different levels of the scaffold, although sometimes steps will be used to improve safety. Connect the first cross- brace to the frame. [, As frames are stacked, cross braces must be of such length as will automatically keep the scaffold plumb, level, and square. Ties, guys, bracing and/or outriggers may be needed to assure a safe, stable scaffold assembly. The momentum of the frame thrust the employee backward off the second level. 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. Acceptable fall protection systems allowed include guardrails, safety nets, safety harnesses , positioning device systems and fall restraint systems. [, Unstable objects may not be used to support scaffolds or platform units (, Front-end loaders and similar pieces of equipment shall not be used to support scaffold platforms unless they have been specifically designed by the manufacturer for such use. 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. Extreme weather or damage to structural components can also affect a scaffold's stability. 3. Wooden platforms (i.e. [, Have rest platforms provided at a maximum of 35 foot vertical intervals. 1. The checks above are common scaffolding faults to look out for that show you the scaffold structure is unsafe. 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 . To accomplish this, the scaffold design must incorporate a realistic . 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. Faults: Damaged. [, Have minimum rung length of 11 inches. "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 . Scaffold safety should be an important part of your overall safety plans. [, Ends of stair rails and handrails constructed so that they do not constitute a projection hazard. Prepares layout, using rule, framing square, and calipers. CALL US AT 877-997-2233. 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). (Figure 4) [, Scaffolds shall be altered only under the supervision and direction of a competent person. [, Portable, hook-on, and attachable ladders must be positioned so as not to tip the scaffold. Fabricated frame scaffolds are the most common type of scaffold because they are versatile, economical, and easy to use. Heavy-duty scaffolds can support 75 pounds per square foot. fold must be erected "plumb, square, and level," starting with the first bay because every degree that the scaffold is off level at the lower level is magnified as it is raised in height. A checklist of items a competent person should complete daily for scaffold safety. 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. Tip: A level may be used frequently during assembly to guarantee that new structural components remain in line. Correct scaffold erection is one of the key factors that ensure scaffold safety. For example, if the base width is three feet, the first vertical tie will be (3 feet x 4) 12 feet from the ground. Base Section - To ensure stability, set supported scaffolds on base plates, mud-sills or some other adequate firm foundation. 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. Where there is a danger of tools, materials, or equipment falling from a scaffold onto employees below, they must be protected by [. The legs, poles, frames, and uprights must bear on base plates and mud sills. Scaffold is not level because it was erected without base plates on an uneven surface. As they were lifting the scaffold, the top section partially separated from the adjoining section, toppled over, and contacted a power line. 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). . He fell 16 feet to the ground, sustaining facial fractures and other injuries. 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 . 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. The maximum intended load and the load-carrying capacity of the scaffold. [, Do not load the scaffold or any component parts beyond their maximum capacity (their own weight and 4:1 the maximum intended load). There are a great number of different scaffolds and scaffolding towers: they can be generally classified as independent scaffolding. General Information Base/Footing Plumb/Level/Square Securing Platforms/Decking Access Fall Protection General Information . A tube and coupler scaffold has a platform(s) supported by tubing, and is erected with coupling devices connecting uprights, braces, bearers and runners. 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. Secure scaffolds to the structure during erection and dismantling. PLUMB/LEVEL/SQUARE. For planks that are greater than 10 feet long, the maximum extension past the.
