When winding drum hoists are used on a suspension scaffold, they shall contain not less than four wraps of the suspension rope at the lowest point of scaffold travel. Unstable objects shall not be used as working platforms. What are the clearance distance between scaffolds and power lines? Guardrail systems shall be installed before the scaffold is released for use by employees other than erection/dismantling crews. 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. The ladder legs shall be secured to prevent them from slipping or being pushed off the platform. Suspension scaffold outrigger beams, when used, shall be made of structural metal or equivalent strength material, and shall be restrained to prevent movement.

A safe point of access should be present during erection and dismantling operations. [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. 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. [29 CFR 1926.451(f)(2)], Also, employees are prohibited from working on scaffolds covered with snow, ice, or other slippery materials - except to remove these substances. To ensure stability for fall protection, scaffolds can be supported by: legs, [29 CFR 1926.451(d)(3)(iv)], Vertical lifelines must not be fastened to counterweights. Stair-rails and handrails must be designed and constructed to prevent punctures, lacerations, snagged clothing, and projection. This provision does not preclude the use of common support members, such as "T" sections, to support abutting planks, or hook on platforms designed to rest on common supports. Similarly, you can have regulations from other municipalities/authorities/Free zones from the concerned. [29 CFR 1926.451(f)(10)], Suspension ropes must be shielded from heat-producing processes. Wondering about scaffold guardrail height requirements? Abrasion, corrosion, scrubbing, flattening or peening causing loss of more than one-third of the original diameter of the outside wires. [29 CFR 1926.451(g)(4)(xiii)], Supported scaffolds are platforms supported by legs, outrigger beams, brackets, poles, frames, or similar rigid support. Horizontal lifelines shall not be attached only to the suspension ropes. Direct access is acceptable when the scaffold is not more than 14 inches (36 centimeters) horizontally and not more than 24 inches (61centimeters) vertically from the other surfaces. Evidence that the secondary brake has been activated during an overspeed condition and has engaged the suspension rope. 10 OSHA Scaffolding Requirements 1. Scaffolds shall be designed by a qualified person and shall be constructed and loaded in accordance with that design. When intermediate members (such as balusters or additional rails) are used, they shall not be more than 19 inches (48 cm) apart. [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. 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. Scaffold components manufactured by different manufacturers shall not be intermixed unless the components fit together without force and the scaffold's structural integrity is maintained by the user. Any part of a scaffold damaged or weakened such that its strength is less than that required by paragraph (a) of this section shall be immediately repaired or replaced, braced to meet those provisions, or removed from service until repaired. When lanyards are connected to horizontal lifelines or structural members on a single-point or two-point adjustable suspension scaffold, the scaffold shall be equipped with additional independent support lines and automatic locking devices capable of stopping the fall of the scaffold in the event one or both of the suspension ropes fail. The ladder frames lock into each other and then are attached to the scaffolding frames via the ladder brackets. 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. Have a maximum spacing between rungs of 16 3/4 inches (43 cm). WebEach 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. When erecting or dismantling tubular welded frame scaffolds, (end) frames, with horizontal members that are parallel, level and are not more than 22 inches apart vertically may be used as climbing devices for access, provided they are erected in a manner that creates a usable ladder and provides good hand hold and foot space. Fork-lifts shall not be used to support scaffold platforms unless the entire platform is attached to the fork and the fork-lift is not moved horizontally while the platform is occupied. 6, 1979, as amended at 58 FR 35182 and 35310, June 30, 1993; 61 FR 46025, Aug. 30 1996; 61 FR 59831, Nov. 25, 1996], Occupational Safety & Health Administration, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Severe Storm and Flood Recovery Assistance. What are some of the requirements for power-operated suspension scaffold hoists? The stall load of any scaffold hoist shall not exceed 3 times its rated load. Before the scaffold is used, direct connections shall be evaluated by a competent person who shall confirm, based on the evaluation, that the supporting surfaces are capable of supporting the loads to be imposed. Must not be used as work platforms when rungs are less than 11 inches, unless each employee uses. Such materials cannot be used as counterweights. Direct connections to roofs and floors, and counterweights used to balance adjustable suspension scaffolds, shall be capable of resisting at least 4 times the tipping moment imposed by the scaffold operating at the rated load of the hoist, or 1.5 (minimum) times the tipping moment imposed by the scaffold operating at the stall load of the hoist, whichever is greater. Capable of withstanding, without failure, a force of at least 50 pounds (222 n) applied in any downward or horizontal direction at any point along the toeboard (toeboards built in accordance with Appendix A to this subpart will be deemed to meet this requirement); and. Scaffolds are commonly used in construction work so workers have a safe, stable work platform when work cannot be done at ground level or on a finished floor. [29 CFR 1926.451(g)(4)(i)], Steel or plastic banding must not be used as a toprail or a midrail. Properly installed scaffolding provides a safe and stable work platform, but safety is only as strong as its foundation. Tables showing maximum permissible spans, rated load capacity, and nominal thickness are in 29 CFR 1926 Subpart L Appendix A(1)(b) & (c) of the standard. When can personal fall-arrest systems be used when working on scaffolding and aerial lifts? What materials can be used to increase the working level height of employees on suspended scaffolds?

Must have rest platforms at 35-foot maximum intervals on all supported scaffolds more than 35 feet high. [29 CFR 1926.451(b)(2)], The standard requires employers to protect each employee on a scaffold more than 10 feet (3.1 m) above a lower level from falling to that lower level. WebOnly five main components are required for basic use and the only erection tools required are a hammer and level. Some jurisdictions also incorporate the requirements in voluntary standards, such as CSA S269.2-M87 Access Each ladder jack scaffold, top plate bracket scaffold, roof bracket scaffold, and pump jack scaffold shall be at least 12 inches (30 cm) wide. [, 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. WORKERS MUST USE FALL PROTECTION WHEN WORKING FROM THIS SCAFFOLD Green: SCAFFOLD IS OK FOR USE Tag must include the scaffold capacity: The manufacturer must approve any alterations to the stilts. Scaffolds are commonly used in construction work so workers have a safe, stable work WebEmployees must pass a written exam and performance evaluation demonstration and must be authorized to operate said equipment. "Access." WebAccess: Scaffolds must have an acceptable form of access (e.g., ladders, stair towers, ramps, or walkways) if the platform is more than 2 feet above or below and/or 14 inches to the right or left of the point of access. Focus on Scaffolding The primary criteria used by the FSC to assess scaffolding work on site are contained within: WH 12 HIRAC FP 4 Management of Subcontractor WHS FP 6 Training arrangements H1 Working at heights Are there specific requirements for outrigger beams? Stilts may be used on a large area scaffold. [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. Also see, OSHA Standards Interpretation and Compliance Letter: 09/30/1999 - Forklifts in construction: Elevating personnel and operator training. How can one prevent supported scaffolding from tipping? Use your safety belts and lanyards when working on scaffolding at a height of 10 feet or more above ground level.
