Scaffolding — Supported Scaffolds

Talking points

1. Every scaffold must support its own weight plus at least four times the maximum intended load without failure.
2. Fall protection is required when the scaffold platform is 10 feet or more above the ground — this means guardrails, PFAS, or both depending on the scaffold type.
3. Scaffold planks must support at least 4 times the load you put on them — scaffold-grade lumber or manufactured decking is the plank graded for exactly that duty. The gap between the platform and the face of the work must not exceed 14 inches (10 inches for plastering and lathing).
4. Mudsills and base plates are required. Never build a scaffold on unstable ground — bricks, blocks, or barrels are not acceptable as a foundation.
5. Toeboards at least 3.5 inches high are required along open edges to prevent tools and materials from falling onto workers below.

What's the first thing you check before stepping onto a scaffold at the start of your shift?
