Personal Fall Arrest Systems 101

Why This Matters

Personal Fall Arrest Systems 101 deserves a specific pre-task check because unprotected edges, openings, fragile surfaces and incorrect fall-arrest setup can lead to severe or fatal falls. For this briefing, connect the topic to the exact equipment, work area and conditions the crew will face today, and agree a clear stop-work trigger before the task begins.

Key Points

• A complete system requires a rated anchor, full-body harness, and connecting device (lanyard or SRL) that are compatible and each individually rated for fall arrest
• The anchor must be positioned to limit both fall distance and pendulum/swing fall potential — anchor location, not just rating, affects outcome severity
• A harness fitted for one worker's size does not distribute arrest forces correctly for a differently sized worker — adjustment must be verified per individual

Best Practices

• Inspect harness, lanyard, and connecting hardware before every use — webbing, stitching, D-rings, and locking mechanisms
• Anchor at or above shoulder height wherever feasible to minimize free fall distance
• Calculate total required fall clearance (free fall, deceleration distance, harness stretch, worker height) before starting work at height
• Verify the anchor point is rated for fall arrest loads through engineering documentation, not visual judgment
• Remove any fall protection equipment showing damage or having arrested a fall from service immediately
• Establish a documented rescue plan before work begins — suspension trauma can become medically significant within minutes of a suspended fall

Scenario & Site Check

Discuss this scenario: A crew is about to start work where personal fall arrest systems 101 is relevant, but one condition in the work area has changed since the task was last performed. Ask the team what could make that change important, which control must be verified first, and who has authority to stop the job.

• Field check: verify edge protection or approved fall system, anchor point, clearance, inspection and rescue plan.
• Evidence: confirm the applicable permit, inspection, label, test result, procedure or equipment status rather than relying only on memory.
• Close-out question: “What would make us stop and reassess this task today?”

Reference Point

Use the current requirement that applies to your site. A useful starting point for Fall Protection is OSHA / NIOSH primary guidance. Company procedures, manufacturer instructions and local law may impose additional or more stringent controls.
