EN 360 – Retractable Fall Arresters (Self-Retracting Lifelines)
EN 360 is the European standard specifying requirements for retractable type fall arresters, also known as self-retracting lifelines, which automatically extend and retract a lifeline while arresting a fall quickly to minimise fall distance and impact force.
1. Scope
EN 360 applies to devices consisting of a drum-wound lanyard or cable that pays out and retracts freely during normal movement, but locks automatically to arrest a fall in the event of a sudden acceleration, typically mounted above the worker’s position.
2. Exclusions & Related Standards
- Connects to a full body harness meeting EN 361 at the dorsal or sternal attachment point.
- Often anchored to a device meeting EN 795.
- Differs from guided type fall arresters on a rigid rail or flexible line under EN 353, which travel along a fixed line rather than retracting from a fixed point.
3. Key Requirements & Marking
Devices must meet requirements for maximum arrest force, maximum fall arrest distance, housing durability, and automatic locking mechanism reliability. Markings include maximum user weight, lifeline length, and compliance with the standard.
4. Testing Overview
Testing includes dynamic fall arrest testing with a test mass to measure arrest force and stopping distance, locking mechanism reliability testing across repeated cycles, housing impact and corrosion resistance, and lifeline material strength and abrasion testing.
5. Selection Guide
Select a retractable fall arrester with a lifeline length matching the work area, confirm the maximum user weight rating (including tools and equipment) is sufficient, and ensure it is anchored appropriately above the work position to minimise potential fall distance and swing hazards.
6. Inspection, Care and Maintenance
- Inspect the housing, lifeline and locking mechanism before every use for damage or contamination
- Test the automatic locking function by pulling sharply on the line before use
- Have the device professionally inspected and serviced at intervals recommended by the manufacturer, typically annually
- Remove from service immediately after arresting a fall, pending manufacturer inspection
7. Frequently Asked Questions
How does a retractable fall arrester work?
The lifeline pays out and retracts freely during normal movement but locks automatically through an internal braking mechanism if it detects a sudden acceleration consistent with a fall.
What is the difference between EN 360 and EN 353?
EN 360 devices retract a lifeline from a fixed point and lock automatically, while EN 353 guided type fall arresters travel along a rigid rail or flexible line as the worker moves.
Can a retractable fall arrester be used horizontally?
Only if specifically rated by the manufacturer for horizontal or lateral use, since many models are designed and tested primarily for overhead vertical anchoring.
Must a retractable fall arrester be removed from service after a fall?
Yes, any device that has arrested a fall must be removed from service and inspected or replaced according to the manufacturer’s instructions before further use.
What harness attachment point should be used with EN 360 devices?
The dorsal (back) attachment point on a full body harness meeting EN 361 is typically used, unless the manufacturer specifies an alternative attachment point.
