c) Added guidance for assessing base soil conditions. Do employees working on supported scaffolds need to be trained? Each platform greater than 10 feet in length shall not extend over its support more than 18 inches (46 cm), unless it is designed and installed so that the cantilevered portion of the platform is able to support employees without tipping, or has guardrails which block employee access to the cantilevered end. [29 CFR 1926.451(g)(1)], To ensure adequate protection, install guardrails along all open sides and ends before releasing the scaffold for use by employees, other than the erection and dismantling crews. [29 CFR 1926.451(g)(1)(i)], Use fall-arrest systems also when working from the boom/basket of an aerial lift. [29 CFR 1926.451(f)(16)], The standard prohibits work on platforms cluttered with debris. At all points of a scaffold where the platform changes direction, such as turning a corner, any platform that rests on a bearer at an angle other than a right angle shall be laid first, and platforms which rest at right angles over the same bearer shall be laid second, on top of the first platform. [, A competent person must inspect ropes for defects prior to each workshift and after every occurrence that could affect a rope's integrity. What are the capacity requirements for all scaffolds? [29 CFR 1926.451(b)(1)], Scaffold planking must be able to support, without failure, its own weight and at least four times the intended load.

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. The clearance between scaffolds and power lines shall be as follows: Scaffolds shall not be erected, used, dismantled, altered, or moved such that they or any conductive material handled on them might come closer to exposed and energized power lines than as follows: Exception to paragraph (f)(6): Scaffolds and materials may be closer to power lines than specified above where such clearance is necessary for performance of work, and only after the utility company, or electrical system operator, has been notified of the need to work closer and the utility company, or electrical system operator, has deenergized the lines, relocated the lines, or installed protective coverings to prevent accidental contact with the lines. [29 CFR 1926.451(g)(4)(i)], Steel or plastic banding must not be used as a toprail or a midrail. Provides general requirements for all scaffolds WebStandards Scaffolding is addressed in specific OSHA standards for general industry, maritime, and construction.
