CLIMBING TECHNIQUES
Various techniques exist for direct progression on a structure using personal fall protection equipment. These techniques can be broadly split into two methods:
1. ‘Aid’ climbing suspended by work positioning lanyards (such as cow’s tails);
2. Climbing with fall arrest equipment (such as energy-absorbing lanyards or pre-installed fall arrest systems).
In some situations, a combination of the two methods may be used. Guidance on other methods, such as lead climbing, is provided in ICOP [TC-102] Part 3, Annex L.
The different methods require specific training with particular reference to their application, and the type of equipment and attachment points used.
Trainees must demonstrate an understanding of the principles of fall factors and clearance distances, and their relevance to the different methods of climbing. Guidance on fall factors, clearance distances and associated risks is provided in ICOP [TC-102] Part 3, Annex Q.
Level 3 candidates shall be able to apply their knowledge by assessing the suitability of the methods of climbing for a variety of scenarios and structures.
HORIZONTAL AID CLIMBING FIXED & MOVEABLE ANCHORS
Horizontal aid climbing is a technique which is commonly used by rope access Technicians to allow them to move across the underside of a structure such as a roof or bridge.
Trainees must demonstrate horizontal aid climbing, progressing primarily in suspension by moving along:
1. Series of fixed anchors.
2. With the use of moveable anchors such as strops or slings.
Trainees must demonstrate a minimum of two independent safety attachments at all times; therefore, the use of at least three lanyards is required.
Trainees must demonstrate an understanding of selecting suitably positioned anchors as well as unquestionably reliable anchors and the need to minimize potential fall distances and impact loads.
Trainees must be aware that this exercise is intended to demonstrate their ability both to move across the structure and to change from aid climbing to ropes and vice versa.
Trainees must demonstrate aid climbing technique for at least 5 m of horizontal movement and, using movable anchors, should pass at least two separate obstructions.
