As explained in the rule and preamble, one situation where the exception would apply is when the platform must fit around uprights when side brackets are used to extend the width of the platform. However, the platform must still be planked or decked as fully as possible. The standard requires that the space between the scaffold planks or between scaffold planks and uprights be no more than one inch wide unless the employer can demonstrate that a wider space is necessary.
In addition, 29 CFR §1926.451(b)(1)(ii) states: 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 ½ inches (24.1 cm). Question: When may the space between scaffold planks or between scaffold planks and uprights exceed one inch in width?Īnswer: The relevant standard, 29 CFR §1926.451(b)(1)(i), states:Įach 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).
