EN 353-2:2002
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.
Key Test Requirements
-
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. -
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 -
Static Strength
Textile lanyards tested at 15 kN for 3 minutes
Metal lanyards tested at 12 kN for 3 minutes -
Corrosion Resistance
Metallic components exposed to salt spray for 24 hours
Must show no rusting or loss of function
EN 353-1 vs EN 353-2
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 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.
