Summary

Introduction to Carabiners

Carabiner's Essential Role

Carabiners are vital links for vertical activities but are vulnerable to misuse, affecting their strength.

Critical Safety: Lever Effect

Hazard of Lever Effect on Gate

Devices can cause a lever effect on the gate, potentially breaking the locking system or causing opening.

Preventing Gate Opening During Descent

Avoid rock impacts and position the locking sleeve correctly to prevent accidental gate opening.

Rope Attachment Procedures

Correct Tying-In Method

Tie directly to the rope or use two locking carabiners in specific low-risk situations.

Lanyard Attachment Options

Securely attach lanyards using a maillon rapide, lark's foot knot, or two carabiners.

Activity-Specific Safety

Via Ferrata STRING Usage

Use STRINGs on lanyards to maintain carabiner position and reduce incorrect loading risks.

Anchor Clipping Risks

Be aware of risks like carabiner over-edge, open gate, or cross-loading when clipping anchors.

Rope Clipping Safety

Preventing Rope Unclipping

Proper rope placement in the carabiner minimizes risks of self-unclipping and whiplash.

One-Handed Clipping Technique

Clip the rope correctly with one hand, ensuring the gate faces away from the direction of progress.

Sling Length and Carabiner Performance

Sling Length's Effect on Strength

Incorrect sling length can lead to gate opening, reducing carabiner strength.

Avoiding Accidental Gate Opening

Choose the right quickdraw to prevent gate opening and over-edge loading from rock contact.

Managing Impact and Vibration

Locking Carabiners for Suspect Anchors

Use locking carabiners with slings to prevent accidental gate opening from impact or anchor failure.

Causes of Carabiner Gate Failure

Sudden loading, energy absorber tears, or rope sliding can cause carabiner gate opening.

Essential Checks and Care

Pre-Use Carabiner Inspection Guide

Inspect carabiner body, gate, and locking system for any damage, wear, or corrosion before each use.

Carabiner Maintenance and Storage

Clean small marks with sandpaper, oil moving parts if needed, and store dry to ensure longevity.

Carabiner Features and Locking Mechanisms

The KEYLOCK System

This notchless closing system prevents the carabiner from accidentally snagging on other equipment.

Overview of Locking Systems

Details various locking systems including Manual, Ball Lock, Tri Act, and Vertigo for secure closure.
