The edge of a scaffold platform that is not cleated shall extend over the centerline of the support by at least how many inches?

The requirement that the edge of a scaffold platform must extend over the centerline of the support by at least 6 inches is anchored in safety regulations for scaffolding. This provision is designed to ensure stability and prevent the risk of the platform tipping or collapsing during use. By requiring a minimum overhang of 6 inches, it allows sufficient support while also providing a margin of safety for workers who may be moving materials or performing tasks near the edges of the scaffolding.

This overhang ensures that the weight distribution on the scaffolding remains balanced, minimizing the chances of accidents that might arise from uneven load or misalignment of the scaffold structure. Proper compliance with such standards is critical in construction environments where workers rely on the integrity of the scaffolding for safety.
