Type: Text Slide with Image


  • Must bear on adequate foundations
  • Unstable objects will not be used as working platforms
  • Plumbed and braced

[Includes photo of scaffolding with improperly supported base plate]

Speaker Notes:

To avoid falls and other hazardous conditions, you should only work from scaffolds that are properly constructed and supported. If the scaffold does not have a stable foundation, then the scaffold may move or shift causing either the scaffold or you to fall.

This scaffold has a base plate but it is not resting on a firm foundation. The base plate is resting on blocks, uneven timbers and planking over uneven ground.
