804 Safe Scaffold Erection and Inspection
Skip to main content

Shore or Lean-to Scaffolds

Shore or lean-to scaffolds are prohibited. They are not properly designed and are a potential safety hazard for anyone who works on them.

Lean-to Scaffold

Storms and High Winds

Fortunately, workers were not on the scaffold (see video) that collapsed during high winds. Working on a scaffold is prohibited during storms or high winds, unless a competent person has determined that it is safe to be on the scaffold and workers are protected by personal fall-arrest systems or wind screens.
