Pre-Work Planning

  • Verify the risk assessment and work permit.
  • Define the safe access and work method.
  • Barricade the area below and prevent unauthorized access.
02REQUIRED

Use Collective Protection

  • Prioritize collective protection using guardrails, platforms or suitable scaffolds; protect openings.
  • OSHA construction: unprotected edges at ≥6 ft (1.8 m) require guardrails, safety nets or personal fall arrest.
  • This threshold is not universal: scaffolds and ladders have separate rules. Lower heights are not automatically safe.
03REQUIRED IF

Full Body Harness

Applies when: Personal fall protection is used

  • Inspect webbing, stitching and labels before every use.
  • Wear, fasten and adjust the harness correctly.
  • Remove damaged or fall-arrested equipment from service.
04REQUIRED IF

Approved Anchorage

Applies when: Personal fall arrest is used

  • Personal fall-arrest anchorages must be independent of anchorages supporting or suspending platforms.
  • OSHA: at least 5,000 lb (22.2 kN) per attached employee; OR the alternative design below.
  • Alternative: a complete system with a safety factor of at least 2, designed, installed and used under a qualified person’s supervision.
05REQUIRED IF

Fall Clearance

Applies when: A fall-arrest system is used

  • Calculate free-fall and total clearance distance.
  • Prevent contact with lower levels or obstructions.
  • Minimize the risk of a swing fall.
06REQUIRED

Safe Access

  • Use inspected access equipment suitable for the task.
  • Maintain three-point contact on ladders.
  • Keep access routes clear, stable and unobstructed.
07REQUIRED IF

Prevent Dropped Objects

Applies when: There is a falling-object hazard

  • Secure tools using a suitable tethering system.
  • Store materials safely away from edges.
  • Isolate the area below and control access.
08REQUIRED IF

Rescue Readiness

Applies when: Personal fall protection or rescue hazards apply

  • Prepare a workable rescue plan before starting.
  • Ensure rescue equipment and trained personnel are available.
  • Verify emergency communication and response arrangements.
