Therefore, to deal with this problem, proposed and final rule paragraph (b)(1) have modified the corresponding requirement of the existing standard by requiring the span between uprights to be planked or decked as fully as possible, but allowing up to 9 ½ inches between the planking or decking and the guardrail supports. This can lead to a significant reduction in plank strength, and possibly cause tipping of the plank (sideways) if eccentrically loaded. As further clarification, the preamble to the final rule, at 61 FR 46039, explains why the exception was added: In order to comply with the existing rule, some employers have modified the last plank (notched slanted, or cut it to size). 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). ![]()
