FallsOSHA Focus Four

Holes and floor openings

Holes, skylights, and penetrations in floors, roofs, and decks. A worker can step or fall through them, or trip in a smaller hole. OSHA requires covers, guardrails, or personal fall arrest for holes more than 6 feet above a lower level.

Where it shows up

  • Mechanical and plumbing penetrations in slabs
  • Skylight openings on roofs
  • Stair and shaft openings before rails go in
  • Removed deck sheets or grating

Controls, most effective first

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

LevelControl
EngineeringCover holes as soon as they are created
Covers strong enough for at least twice the weight of workers, equipment, and materials that may cross them
Secure covers so wind, equipment, or workers cannot move them
Guardrails around openings too large to cover
AdministrativeMark covers "HOLE" or "COVER", or color code them
Only the foreman or competent person removes a cover, and the hole is guarded while open
Walk the area at the start of the shift to check every cover
PPEPersonal fall arrest when working at an open hole
