Key issues and risks

The fall-arrest lanyard is not under tension, but must be able to stop a fall at any time.

The carabiner must be easily attachable to various anchors, sometimes of large diameter, so its shape must be chosen with care.

The most important risks to consider

Recommendation on carabiner and accessories

- Use a carabiner shape suitable for the anchors you encounter

- Use a carabiner positioning system (STRING or plastic sleeve) or a directional carabiner

Good anchor placement and controlled situations

In most work situations, the anchors are planned and placed to limit risks in the event of a fall.

  • Speed of use
  • Shape suitable for large-diameter anchors

Difficult anchors and situations

When the anchor placement does not allow for control over all potential rub points or bad placements, use carabiners that are certified to ANSI or CSA North American standards, which have locking sleeves with greater resistance to external pressure.

Information

With the ABSORBICA TIE-BACK lanyard:

Be careful in selecting your lanyard-end connector. If the connector has a protruding nose, relative to the gate, the gate can snag on a textile part of the lanyard (intermediate attachment ring). So there is a risk of the lanyard disconnecting in the event of a fall while wrapping a beam.

Usage precautions

  • Beware of the position of the carabiner in the anchor and of possible external pressure situations around the anchor that can produce cantilever loading.
  • When clipping, check that the carabiner is correctly positioned in the anchor, and that the sleeve is completely locked.
  • Plan your movements during use to anticipate the movement of the carabiners and the risks of poor positioning.
  • Use a locking system suited to your frequency of connection/disconnection.

Notes

The SL manual locking system can be used, specifically in dirty environments (mud, sand...), taking into account the risk of the sleeve opening in use and the risk of forgetting to lock the sleeve at each connection.
