This provision does not preclude the use of systems which are designed to function both as suspension scaffolds and emergency systems. When scaffold platforms are more than 2 feet (0.6 m) above or below a point of access, portable ladders, hook-on ladders, attachable ladders, stair towers (scaffold stairways/towers), stairway-type ladders (such as ladder stands), ramps, walkways, integral prefabricated scaffold access, or direct access from another scaffold, structure, personnel hoist, or similar surface shall be used. When midrails are used, they shall be installed at a height approximately midway between the top edge of the guardrail system and the platform surface. Some of the requirements for all types of suspension scaffolds include: Counterweights used to balance adjustable suspension scaffolds must be able to resist at least four times the tipping moment imposed by the scaffold operating at either the rated load of the hoist, or one-and-a-half (minimum) times the tipping moment imposed by the scaffold operating at the stall load of the hoist, whichever is greater. Must have their bottom step no more than 24 inches above the level on which the scaffold is supported. [, When lanyards are connected to horizontal lifelines or structural members on single-point or two-point adjustable scaffolds, the scaffold must have additional independent support lines equal in number and strength to the suspension lines and have automatic locking devices. [, When scaffold platforms are more than 24 inches (61 cm) above or below a point of access, ladders, ramps, walkways, or similar surfaces must be used. WebDetermines that each scaffold and scaffold component shall be capable of supporting, without failure, its own weight and at least 4 times the maximum intended load applied or Each platform on all working levels of scaffolds shall be fully planked or decked between the front uprights and the guardrail supports as follows: Each platform unit (e.g., scaffold plank, fabricated plank, fabricated deck, or fabricated platform) shall be installed so that the space between adjacent units and the space between the platform and the uprights is no more than 1 inch (2.5 cm) wide, except where the employer can demonstrate that a wider space is necessary (for example, to fit around uprights when side brackets are used to extend the width of the platform). [29 CFR 1926.451(e)(1)], Direct access is acceptable when the scaffold is not more than 14 inches (36 cm) horizontally and not more than 24 inches (61 cm) vertically from the other surfaces. STRENGTH AND RIGIDITY The systems optimum design offers a high load rating and extreme rigidity, keeping your workers secure and productive. [29 CFR 1926.451(d)(13)], These hoists require a positive crank force to descend. [, When employees are plastering and lathing 18 inches (46 cm) or less from the front edge. Where there is a danger of tools, materials, or equipment falling from a scaffold and striking employees below, the following provisions apply: The area below the scaffold to which objects can fall shall be barricaded, and employees shall not be permitted to enter the hazard area; or. [, Ladders, such as portable, hook-on, attachable, and stairway [. May forklifts, front-end loaders, or similar equipment support platforms? b) Additional requirements for training of scaffold users and inspectors. NOTE: As of January 1, 1998, subpart M of this part provides that body belts are not acceptable as part of a personal fall arrest system. Must have slip-resistant surfaces on all treads and landings. Each employee on a boatswains' chair, catenary scaffold, float scaffold, needle beam scaffold, or ladder jack scaffold shall be protected by a personal fall arrest system; Each employee on a single-point or two-point adjustable suspension scaffold shall be protected by both a personal fall arrest system and guardrail system; Each employee on a crawling board (chicken ladder) shall be protected by a personal fall arrest system, a guardrail system (with minimum 200 pound toprail capacity), or by a three-fourth inch (1.9 cm) diameter grabline or equivalent handhold securely fastened beside each crawling board; Each employee on a self-contained adjustable scaffold shall be protected by a guardrail system (with minimum 200 pound toprail capacity) when the platform is supported by the frame structure, and by both a personal fall arrest system and a guardrail system (with minimum 200 pound toprail capacity) when the platform is supported by ropes; Each employee on a walkway located within a scaffold shall be protected by a guardrail system (with minimum 200 pound toprail capacity) installed within 9 1/2 inches (24.1 cm) of and along at least one side of the walkway. Steps and rungs of ladders and stairways must line up vertically with each other between rest platforms. [29 CFR 1926.451(a)(6)] Scaffolds and scaffold components must not be loaded in excess of their maximum intended loads or rated capacities, whichever is less. To reduce the possibility of welding current arcing through the suspension wire rope when performing welding from suspended scaffolds, the following precautions shall be taken, as applicable: An insulated thimble shall be used to attach each suspension wire rope to its hanging support (such as cornice hook or outrigger). maximum lift heights.

[29 CFR 1926.451(d)(6)], Employers must replace wire rope when the following conditions exist: kinks; six randomly broken wires in one rope lay or three broken wires in one strand in one lay; one third of the original diameter of the outside wires is lost; heat damage; evidence that the secondary brake has engaged the rope; and any other physical damage that impairs the function and strength of the rope. Direct access to or from another surface shall be used only when the scaffold is not more than 14 inches (36 cm) horizontally and not more than 24 inches (61 cm) vertically from the other surface. How to reduce the risk of injury when using bakers scaffolds [29 CFR 1926.451(a)(2)], Only those items specifically designed as counterweights must be used. Where scaffolds must be used in areas that the employer can demonstrate are so narrow that platforms and walkways cannot be at least 18 inches (46 cm) wide, such platforms and walkways shall be as wide as feasible, and employees on those platforms and walkways shall be protected from fall hazards by the use of guardrails and/or personal fall arrest systems. Employers are required to provide fall protection for employees erecting or dismantling supported scaffolds where the installation and use of such protection is feasible and does not create a greater hazard. Are there requirements for suspension ropes? A toeboard shall be erected along the edge of platforms more than 10 feet (3.1 m) 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 (2 x 4 cm) wood or equivalent may be used in lieu of toeboards; Where tools, materials, or equipment are piled to a height higher than the top edge of the toeboard, paneling or screening extending from the toeboard or platform to the top of the guardrail shall be erected for a distance sufficient to protect employees below; or, A guardrail system shall be installed with openings small enough to prevent passage of potential falling objects; or. Direct access to or from another surface shall only be used when the scaffold is not more than 14 inches horizontally and 24 inches vertically from the other surface. Scaffolds (Staging). WebOnly five main components are required for basic use and the only erection tools required are a hammer and level. When midrails, screens, mesh, intermediate vertical members, solid panels, or equivalent structural members are used, they shall be installed between the top edge of the guardrail system and the scaffold platform. [29 CFR 1926.451(e)(1)], Effective September 2, 1997, employees erecting and dismantling supported scaffolding must have a safe means of access provided when a competent person has determined the feasibility and analyzed the site conditions. Must have a maximum space between rungs of 16 inches. Counterweights shall be made of non-flowable material. Safe points of anchorage include structural members of buildings, but do not include standpipes, vents, other piping systems, electrical conduit, outrigger beams, or counterweights. Portable, hook-on, and attachable ladders (Additional requirements for the proper construction and use of portable ladders are contained in subpart X of this part -- Stairways and Ladders): Portable, hook-on, and attachable ladders shall be positioned so as not to tip the scaffold; Hook-on and attachable ladders shall be positioned so that their bottom rung is not more than 24 inches (61 cm) above the scaffold supporting level; When hook-on and attachable ladders are used on a supported scaffold more than 35 feet (10.7 m) high, they shall have rest platforms at 35-foot (10.7 m) maximum vertical intervals. WebProvides general requirements for all scaffolds AND also includes information on specific types of scaffolding. Must have their lowest rung no more than 24 inches above the level on which the scaffold is supported. Must have a minimum rung length of 11 inches, and a maximum space between rungs of 16 inches. WebScaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures.Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Must have rest platforms at 35-foot maximum intervals on all supported scaffolds more than 35 feet high. When do supported scaffolds need to be restrained from tipping? Wondering about scaffold guardrail height requirements? Sound points of anchorage include structural members, but do not include standpipes, vents, other piping systems, or electrical conduit. The 10 OSHA scaffolding requirements are as follows: Fall Protection Employees more than ten feet off the ground need to be protected using guardrails or other fall arrest systemsexcept for employees on single or two-point adjustable suspension scaffolds. Toeboards shall be securely fastened in place at the outermost edge of the platform and have not more than 1/4 inch (0.7 cm) clearance above the walking/working surface. Handrails, and toprails that serve as handrails, shall provide an adequate handhold for employees grasping them to avoid falling. Each scaffold and scaffold component must support without failure its own weight and at least 4 times the maximum intended load applied or transmitted to it. Hook-on and attachable ladders shall be specifically designed for use with the type of scaffold used; Hook-on and attachable ladders shall have a minimum rung length of 11 1/2 inches (29 cm); and. Steps and rungs of ladder and stairway type access shall line up vertically with each other between rest platforms. The top guy, tie or brace of completed scaffolds shall be placed no further than the 4:1 height from the top. A stairrail consisting of a toprail and a midrail shall be provided on each side of each scaffold stairway. Must be uniformly spaced within each frame section. [, When using direct access, the surface must not be more than 24 inches (61 cm) above or 14 inches (36 cm) horizontally from the surface. Fall protection includes guardrail systems and personal fall arrest systems. Counterweights shall not be removed from an outrigger beam until the scaffold is disassembled. Each platform must be planked and decked as fully as possible with the space between the platform and uprights not more than 1 inch (2.5 cm) wide. Stairrail systems and handrails shall be surfaced to prevent injury to employees from punctures or lacerations, and to prevent snagging of clothing. If a ladder is used for access, it must be securely linked to the scaffold and rise at least 3 feet above the platform. Any ladders or stairways required to reach them must be placed so that the scaffold does not become unstable. What Are the Requirements for Supported Scaffolds? Excess suspension wire rope and any additional independent lines from grounding shall be insulated; The suspension wire rope shall be covered with insulating material extending at least 4 feet (1.2 m) above the hoist. Scaffolds shall be erected, moved, dismantled, or altered only under the supervision and direction of a competent person qualified in scaffold erection, moving, dismantling or alteration. insulated protective covers cover the hoist. What are scaffold platform construction requirements? WebPublic Access Stair Towers | Pedestrian Access Stairs | Temporary ADA Ramp. e) Modified requirements for guardrails. [29 CFR 1926.451(h)(1), 29 CFR 1926.451(h)(2) and 29 CFR 1926.451(h)(3)], Occupational Safety & Health Administration, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers. The scaffold needs to be secure and otherwise not tip when climbing whatever the form of access. Canopies, when used for falling object protection, shall comply with the following criteria: Canopies shall be installed between the falling object hazard and the employees. However, where the employer can demonstrate that it is not possible to place an outrigger beam perpendicular to the face of the building or structure because of obstructions that cannot be moved, the outrigger beam may be placed at some other angle, provided opposing angle tiebacks are used. A. The standard prohibits using repaired wire. The top edge height of toprails or equivalent member on supported scaffolds manufactured or placed in service after January 1, 2000 shall be installed between 38 inches (0.97 m) and 45 inches (1.2 m) above the platform surface. Ties, guys, braces, or outriggers shall be used to prevent the tipping of supported scaffolds in all circumstances where an eccentric load, such as a cantilevered work platform, is applied or is transmitted to the scaffold. [29 CFR 1926.451(e)(8)], The standard prohibits the use of crossbraces as a means of access. How can one prevent supported scaffolding from tipping? Ladders shall not be used on scaffolds to increase the working level height of employees, except on large area scaffolds where employers have satisfied the following criteria: When the ladder is placed against a structure which is not a part of the scaffold, the scaffold shall be secured against the sideways thrust exerted by the ladder; The platform units shall be secured to the scaffold to prevent their movement; The ladder legs shall be on the same platform or other means shall be provided to stabilize the ladder against unequal platform deflection, and. This determination shall be based on site conditions and the type of scaffold being erected or dismantled. In general, each scaffold and scaffold component shall be capable of supporting, without failure, its own weight and at least 4 times the maximum intended load applied or transmitted to it. above the scaffold supporting level. Sound anchorages include structural members, but do not include standpipes, vents, other piping systems, or electrical conduit. [29 CFR 1926.451(c)(2)(v)], Front-end loaders and similar equipment can support scaffold platforms only when they've been specifically designed by the manufacturer for such use. Guardrail systems shall be installed before the scaffold is released for use by employees other than erection/dismantling crews. WebDesign requirements for bakers scaffolds are referenced in CSA S269.2 Access Scaffolding for Construction Purposes. [, A competent person must evaluate all direct connections prior to use to confirm that the supporting surfaces are able to support the imposed load. Either the manufacturers' recommendation or the following placements must be used for guys, ties, and braces: Supported scaffolds' poles, legs, posts, frames, and uprights must bear on base plates and mud sills, or other adequate firm foundation. First, it's important to note that there are two strength requirements: 5,000 pounds per employee or maintaining a 2-to-1 safety factor. [29 CFR 1926.451(c)(2)(i) and 29 CFR 1926.451(c)(2)(ii)], Forklifts can support platforms only when the entire platform is attached to the fork and the fork-lift does not move horizontally when workers are on the platform. When a guardrail system is used, the guardrail height must be increased in height equal to the height of the stilts. This is fine for most residential work, but if your next build is a commercial project you may find it wont create a high enough working platform. How wide does the work area need to be on scaffolding? Two-point and multi-point suspension scaffolds shall be tied or otherwise secured to prevent them from swaying, as determined to be necessary based on an evaluation by a competent person. Makeshift devices, such as but not limited to boxes and barrels, shall not be used on top of scaffold platforms to increase the working level height of employees. [, A competent person must inspect ropes for defects prior to each workshift and after every occurrence that could affect a rope's integrity. A landing platform at least 18 inches (45.7 cm) wide by at least 18 inches (45.7 cm) long shall be provided at each level. Single tiebacks installed at an angle are prohibited.
