Outrigger beams which are not stabilized by bolts or other direct connections to the floor or roof deck shall be secured by tiebacks. This determination shall be based on site conditions and the type of scaffold being erected or dismantled. Vertical lifelines shall not be used when overhead components, such as overhead protection or additional platform levels, are part of a single-point or two-point adjustable suspension scaffold. The ends of all rails shall not overhang the terminal posts except when such overhang does not constitute a projection hazard to employees. The top guy, tie or brace of completed scaffolds shall be placed no further than the 4:1 height from the top. A canopy structure, debris net, or catch platform strong enough to withstand the impact forces of the potential falling objects shall be erected over the employees below. 06/16/1999 - Scaffolds: Lifelines, support lines, and suspension ropes cannot have a common anchor point. Paragraph (g)(2) of this section addresses fall protection for scaffold erectors and dismantlers. 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. Each toprail or equivalent member of a guardrail system shall be capable of withstanding, without failure, a force applied in any downward or horizontal direction at any point along its top edge of at least 100 pounds (445 n) for guardrail systems installed on single-point adjustable suspension scaffolds or two-point adjustable suspension scaffolds, and at least 200 pounds (890 n) for guardrail systems installed on all other scaffolds.

When a guardrail system is used, the guardrail height must be increased in height equal to the height of the stilts. [, All support devices must rest on surfaces capable of supporting at least four times the load imposed on them by the scaffold when operating at the rated load of the hoist, or at least one-and-a-half times the load imposed on them by the scaffold at the stall capacity of the hoist, whichever is greater. [29 CFR 1926.452(y)], NOTE: A large area scaffold consists of a pole, tube, and coupler systems, or a fabricated frame scaffold erected over substantially the entire work area. The inboard ends of suspension scaffold outrigger beams shall be stabilized by bolts or other direct connections to the floor or roof deck, or they shall have their inboard ends stabilized by counterweights, except masons' multi-point adjustable suspension scaffold outrigger beams shall not be stabilized by counterweights. 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. The manufacturer must approve any alterations to the stilts. Scaffold planking must be able to support, without failure, its own weight and at least four times the intended load.

[, Employers must ensure that all employees are trained to recognize the hazards associated with the type of scaffold being used. Must have a rung length of at least 8 inches. Each suspension rope, including connecting hardware, used on adjustable suspension scaffolds shall be capable of supporting, without failure, at least 6 times the maximum intended load applied or transmitted to that rope with the scaffold operating at either the rated load of the hoist, or 2 (minimum) times the stall load of the hoist, whichever is greater. Stairways shall be installed between 40 degrees and 60 degrees from the horizontal. Any of these independent modules or units should form a base. Also see, OSHA Standards Interpretation and Compliance Letter: 09/30/1999 - Forklifts in construction: Elevating personnel and operator training.

[29 CFR 1926.451(a)(5)], The stall load is the load at which the prime-mover (motor or engine) of a power-operated hoist stalls or the power to the prime-mover is automatically disconnected. Our Office Location. Crossbracing is acceptable in place of a midrail when the crossing point of two braces is between 20 inches (0.5 m) and 30 inches (0.8 m) above the work platform or as a toprail when the crossing point of two braces is between 38 inches (0.97 m) and 48 inches (1.3 m) above the work platform. 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. When Scaffolding is Needed The very short answer is: when a risk assessment outlines it is necessary! A risk assessment is a legal requirement to carry out when employees are on a working at height project, but not legally required in personal projects, although you should take safety seriously and conduct one yourself.
