Frequently asked questions: Safety Karabiners
What are safety karabiners used for?
A karabiner is a connector that links parts of the fall-arrest system, such as a harness, lanyard, lifeline or anchor. It must have a screw-gate or automatic closure, to prevent accidental opening under load. It is used for work at height on scaffolding, plant and metal structures, where the connection must never open by itself.
Which standard applies to karabiners for fall protection?
Connectors for fall-arrest systems must comply with EN 362, which defines the strength, opening and marking of karabiners. The marking with the standard and the instructions for use must be printed on the body of the karabiner. Do not use a karabiner without legible marking to connect it to a protection system.
Screw-gate or double-action karabiner: which to choose?
A screw-gate karabiner, such as the ligam screw or the Portwest FP30 screw-gate karabiner, closes with a screw and must be screwed fully home. The double-action type closes with a snap and opens with a safety lever. Automatic closure is convenient for frequent use, but the closure must always be checked before loading the connector.
Which variables matter when choosing a karabiner?
The main variables are the material, aluminium or steel, the type of closure, the gate opening and the rated load. The range includes steel karabiners, such as the EN double from SpanSet, and aluminium ones, such as the Sm’D from Petzl. Aluminium is lighter, steel is heavier, and the choice depends on the connection and the working environment.
Which hook does a scaffolder need?
For scaffolders the range offers the CSC Edilizia scaffolder’s hook, the Portwest FP37 tower hook and the Portwest FP35 scaffold hook, designed to hook onto tubes and structures. Check that the opening is compatible with the diameter of the tube or structure you are hooking onto. A hook that does not fit correctly must not be forced.
What is the difference between a screw connector and a twist-lock?
The screw connector, such as the half-turn model or the Delta from SpanSet, closes by screwing the collar fully home. The Portwest FP33 Twist-lock and the Vertigo Twist-Lock from Petzl close by rotating a collar and remain locked in position. Both must be checked before use to verify that the collar is fully closed.
How do you use a karabiner safely?
Use the karabiner only on the indicated anchor point and check that the closure is complete before loading it. Do not work with the gate resting on the edge of a structure or on an unsuitable tube. Do not open or modify the karabiner, and replace it if the closure no longer locks properly.
Can a tool karabiner serve as a fall-arrest connector?
No. A tool karabiner, such as the MINO from Petzl, keeps tools or small objects within reach, attached to the harness, without leaving them in passageways. It is not a fall-arrest connector and must not be connected to the safety line. Choose the model according to the weight of the tool and the type of closure.
