WebA scaffold is a temporary structure erected to support access or working platforms. 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. Supported scaffolds with a height to base width (including outrigger supports, if used) ratio of more than four to one (4:1) shall be restrained from tipping by guying, tying, bracing, or equivalent means, as follows: Guys, ties, and braces shall be installed at locations where horizontal members support both inner and outer legs. WebWhen 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 Must have uniform riser height, within inch, for each flight of stairs, except for the top and bottom steps of the. Hook-on and attachable ladders shall have uniformly spaced rungs with a maximum spacing between rungs of 16 3/4 inches. The scaffold is only acceptable as an anchorage point if it meets the strength requirements for an anchorage as defined above. This section does not apply to aerial lifts, the criteria for which are set out exclusively in 1926.453. On scaffolds where scaffold planks are abutted to create a long platform, each abutted end shall rest on a separate support surface. 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.

Construction materials such as, but not limited to, masonry units and rolls of roofing felt, shall not be used as counterweights. 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. 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). Exception to paragraph (b)(1): The requirement in paragraph (b)(1) to provide full planking or decking does not apply to platforms used solely as walkways or solely by employees performing scaffold erection or dismantling. The platform must not deflect more than 1/60 of the span when loaded. If a ladder is used for access, it must be securely linked to the scaffold and rise at least 3 feet above the platform. [29 CFR 1926.451(f)(11)], Power-operated hoists used to raise or lower a suspended scaffold must be tested by a qualified testing laboratory.

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.
