The method and conditions of use of guided type fall arresters (and safety line adjustment devices) are not only influenced by the requirements of the technical standards (differences between requirements of EN 353-2 and EN 12841 were described in this article), but are mainly based on the manufacturer’s instructions.

It can often happen that seemingly identical fall arresters, meeting the requirements of the same standard, cannot be used the same way or with the same connecting equipment. This can lead to complications in cases when rope technicians with different fall arresters meet at the same workplace and the manufacturer’s instructions are not available at the moment.

Therefore the following table provides an overview of the most frequently used fall arresters and the conditions of their use in accordance with EN 12841 A (Personal fall protection equipment – Rope access systems – Rope adjustment devices – type A: safety line adjustment devices).
