Overlap
Platform planks overlapped to create a long platform should overlap at least 12 inches beyond supports, unless the planks are nailed together or otherwise restrained so they do not move.
Abutted Planks
When platform units are abutted together or overlapped to make a long platform, ensure each end rests on a separate support or equivalent support.
Platform Lengths
A platform 10 feet or less in length should generally extend at least 6 inches, but no more than 12 inches, beyond its support, unless the excess length is guarded or can support workers and material without tipping.
A platform longer than 10 feet should generally extend no more than 18 inches beyond a support unless the excess length is guarded or can support workers and material without tipping.
