What is a Personal Fall Arrest System (PFAS)?

June 22, 2025

A Personal Fall Arrest System (PFAS) is your last line of defense in the event of a fall. But simply wearing the gear isn’t enough — it must be set up and used correctly to do its job. If not, it’s just extra weight.

Why It Matters

A PFAS doesn’t stop you from falling — it stops you from hitting the ground.

But it only works if every component is properly selected, connected, rated, and inspected.

A small mistake in the setup can result in total system failure.

Key Points

✅ A complete PFAS includes:

  • Full-body harness
  • Shock-absorbing lanyard or self-retracting lifeline (SRL)
  • Certified anchor point

Additional PFAS safety requirements:

  • All components must be compatible and rated for at least 5,000 lbs
  • Never connect to non-rated anchors like guardrails, pipes, or scaffolding crossbars
  • Calculate fall clearance distance — if your lanyard is too long or the anchor point is too low, you could still hit the ground
  • Inspect all components regularly for damage, fraying, corrosion, or wear
  • Make sure your harness fits properly — loose straps can cause injury even if the fall is arrested
  • Training is key — every worker should know how to inspect and tie off correctly

Bottom line: Your PFAS is only effective if it’s set up correctly and inspected before use.

Ask the Crew

  • What are the three components of a complete PFAS?
  • How far will you fall before the system engages?
  • Are you confident your anchor point is certified and rated?
  • Has your gear been inspected today?
  • Do you know who to ask if you’re not sure about your setup?
