FallsOSHA Focus Four

Falls from height

Work at an unprotected side or edge 6 feet or more above a lower level. In construction, 29 CFR 1926.501(b)(1) requires guardrails, safety nets, or a personal fall arrest system at that height.

Where it shows up

  • Leading edges on metal deck or formwork
  • Roof edges and low-slope roofs
  • Slab edges before perimeter protection goes up
  • Elevator shafts and stair openings
  • Climbing rebar walls or columns

Controls, most effective first

Work down the list. Rely on PPE only for the risk the controls above it cannot remove.
