EN 353-2

Guided Type Fall Arresters with Flexible Anchor Lines

Working at height requires reliable protection. EN 353-2:2002 defines the requirements for guided type fall arresters with flexible anchor lines. These systems allow workers to climb or descend safely while connected to a travelling device. In the event of a fall, the device locks onto the line and arrests the fall within strict performance limits.

As part of the European framework for fall protection, EN 353-2 systems must be combined with a certified full-body harness (EN 361) as part of a complete fall arrest system (EN 363).

How EN 353-2 Systems Work

A flexible anchor line (rope, wire, or textile) is secured to an upper anchor point. A travelling device moves along the line with the user during ascent or descent. If a fall occurs, the device grips the line and stops the fall, minimizing arrest distance and forces.

Requirements

Requirements

1. Dynamic Performance

  • Tested with a 100 kg mass dropped from the maximum permitted distance.
  • Arrest distance must not exceed 1 meter.
  • Maximum arrest force: 6 kN.

2. Locking After Conditioning

Devices must still lock effectively after environmental exposure:

  • Heat: 50°C at 85% humidity for 2 hours
  • Cold: -30°C for 2 hours
  • Water spray: 70 L/hour for 3 hours
  • Optional: immersion in diesel oil or dust

3. Static Strength

  • Textile lanyards tested at 15 kN for 3 minutes
  • Metal lanyards tested at 12 kN for 3 minutes

4. Corrosion Resistance

  • Metallic components exposed to salt spray for 24 hours
  • Must show no rusting or loss of function

Comparison

Guided Fall Arrester Standards Comparison

Both standards cover guided fall arresters, but with different anchor line types:

Feature EN 353-1 (Rigid Anchor Lines) EN 353-2 (Flexible Anchor Lines)
Anchor line type Rigid (rails, fixed ladders) Flexible (rope, wire, textile)
Installation Permanent, vertical or up to 15° angle Temporary or permanent, vertical
Mobility Travelling device moves along rigid guide Travelling device moves along rope/line
Applications Fixed ladders, towers, masts Scaffolding, temporary structures, towers
Multi-user use Not included Not included

Why EN 353-2 Matters

Flexible Fall Arrest Systems

Flexible fall arrest systems are essential in industries where access points change frequently or where rigid lines are impractical:

  • Maritime & offshore: flexible systems on cranes, scaffolding, or temporary rig structures.
  • Petrochemical: access to tall tanks, maintenance points, and refinery equipment.
  • Construction: scaffolding, ladders, and temporary worksites with varying anchor points.

By specifying strict test methods, EN 353-2 ensures that equipment can withstand real-world conditions such as temperature extremes, water exposure, and corrosion.

Frequently Asked Questions

What is the difference between EN 353-1 and EN 353-2?
EN 353-1 covers rigid anchor line systems (fixed ladders, rails). EN 353-2 covers flexible anchor line systems (ropes, cables).
Can multiple users connect to an EN 353-2 system?
No. Both EN 353-1 and EN 353-2 systems are designed for single-user use only.
Does the standard require an energy absorber?
Energy absorbers are detailed separately in EN 355, but EN 353-2 systems may incorporate energy absorbing elements as part of their design.
How strong must flexible anchor lines be?
  • Textile: at least 15 kN for 3 minutes
  • Metal: at least 12 kN for 3 minutes
Why test for corrosion resistance?
To ensure long-term performance in harsh outdoor or marine environments where rust and salt exposure are common.
