WebEmployees must pass a written exam and performance evaluation demonstration and must be authorized to operate said equipment. Platforms may be coated periodically with wood preservatives, fire-retardant finishes, and slip-resistant finishes; however, the coating may not obscure the top or bottom wood surfaces. 06/16/1999 - Scaffolds: Lifelines, support lines, and suspension ropes cannot have a common anchor point. What types of scaffolds does the standard prohibit? Webf. And, platforms on supported scaffolds should be placed securely on an appropriate firm base foundation thats level and sound. Ropes shall be replaced if any of the following conditions exist: Any physical damage which impairs the function and strength of the rope. 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.

Heat damage caused by a torch or any damage caused by contact with electrical wires. In addition, masons' multi-point adjustable suspension scaffold connections shall be designed by an engineer experienced in such scaffold design. 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. Must have a slope of no more than 1 vertical to 3 horizontal degrees (20 degrees above the horizontal).

The top guy, tie or brace of completed scaffolds shall be placed no further than the 4:1 height from the top. 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. e) Modified requirements for guardrails. However, OSHA permits direct access from another scaffold, structure, or personnel hoist. [29 CFR 1926.451(g)(2)]. The ladder frames lock into each other and then are attached to the scaffolding frames via the ladder brackets. Guys, ties, and braces shall be installed according to the scaffold manufacturer's recommendations or at the closest horizontal member to the 4:1 height and be repeated vertically at locations of horizontal members every 20 feet (6.1 m) or less thereafter for scaffolds 3 feet (0.91 m) wide or less, and every 26 feet (7.9 m) or less thereafter for scaffolds greater than 3 feet (0.91 m) wide. Here are the scaffold guardrail 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. DESIGN & ENGINEERING. Must have rest platforms at 12-foot maximum intervals. This paragraph applies to scaffold access for all employees. Where the employer makes the demonstration provided for in paragraph (b)(1)(i) of this section, the platform shall be planked or decked as fully as possible and the remaining open space between the platform and the uprights shall not exceed 9 1/2 inches (24.1 cm). Suspension scaffold hoists and non-walk-through stirrups may be used as end guardrails, if the space between the hoist or stirrup and the side guardrail or structure does not allow passage of an employee to the end of the scaffold. "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. [29 CFR 1926.451(d)(3)(ii) and 29 CFR 1926.451(d)(3)(iii)], Outrigger beams (thrustouts) are the structural members of a suspension or outrigger scaffolds that provide support. 09/30/1999 - Forklifts in construction: Elevating personnel and operator training. [, When outrigger scaffolds are 3 inches (8 cm) or less from the front edge. 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. This includes ladders, boxes, and barrels. 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(g)(3)(i)], No. This provision does not preclude the use of systems which are designed to function both as suspension scaffolds and emergency systems. 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. 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. insulated protective covers cover the hoist.
