Position the first level of bracing as close to the base as possible. The nature of any electrical hazards, fall hazards, and falling object hazards in the work area. Top rails must be capable of supporting at least 200 pounds applied in a downward or outward direction. Cross-bracing is required on both front and back sides of each scaffold buck or frame. Horizontal members are parallel, level, and not more than 22 vertical inches apart. Because the frames are stacked, the cross braces have to keep the scaffold plumb, level, and square. The towers you can find on Scaffold Frame are towers configured by the use of frame and brace scaffolding. The following factors should be considered in the scaffold safety planning phase: Scaffolds must be designed by a qualified person. Scaffolds and scaffold components must be capable of supporting, without failure, their own weight and at least 4 times their maximum intended load. [, 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. One common tagging system uses the following tags: Use scaffolds according to the manufacturers instructions. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the supervision of a scaffold competent person.

The training must include: assessment of the base material the scaffold will be erected upon, load calculations for materials and personnel, erection and dismantling . Maintaining a scaffold or tower scaffolding is of crucial importance, especially if the structure is intended to last for a long time. Since it is an elevated platform, the stability decreases as the height increases. [, Do not load the scaffold or any component parts beyond their maximum capacity (their own weight and 4:1 the maximum intended load). Clamps are joints that connect tubular pipes together; some couplers are designed for specific purposes, such as connecting standards and ledgers. [29 CFR 1926.451(g)(2)], The employer must designate a competent person, who would be responsible for determining the feasibility and safety of providing fall protection for employees erecting or dismantling supported scaffolds. 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. [, Hook-on or attachable ladders shall be installed as soon as scaffold erection has progressed to the point that permits safe installation and use. He fell, sustaining a concussion for which he was hospitalized. Bracing Connect panels and frames with diagonal, horizontal, or cross braces along or as a combination, in order to laterally secure the vertical members. The technical storage or access that is used exclusively for anonymous statistical purposes. NOTE: Except where indicated, these requirements also apply to manually propelled, pump jack, ladder jack, tube and coupler, and pole scaffolds, as well as the specialty scaffolds described in the Supported Scaffolds module.
