Scaffold planks must extend past end supports at least how many inches?

Explanation:
Plank overhang is about ensuring secure bearing and edge safety on scaffold ends. The minimum overhang is six inches, which makes sure enough of the plank rests on the end support to keep it stable and reduce the chance of slipping off the end. If the overhang were only four inches or less, the plank would have inadequate bearing and could shift, tip, or fail when weight is applied near the edge. So six inches is the safe, required minimum.
