Application
This unit describes the performance outcomes, skills and knowledge required to select and set up belay systems and ropes suitable for single pitch recreational abseils on natural surfaces, such as cliff faces, and according to current conditions. It requires the ability to select the abseil route and to select and utilise fixed artificial, naturally occurring or artificial removable anchors.
It applies to rigging staff and activity leaders who work independently or with limited guidance from others.
This unit applies to any type of organisation that delivers outdoor recreation activities including commercial, not-for-profit and government organisations.
No occupational licensing, certification or specific legislative requirements apply to this unit at the time of publication.

2. Set up belay system for natural surface abseils.
|
2.1. Select anchors and assess condition, including performance under likely load and stability of surroundings.
2.2. Rig or establish multiple anchors, ensuring equalisation and minimise potential for shock loading.
2.3. Select and tie appropriate knots, and rig ropes suitable for load and function within the belay system.
2.4. Establish a belay from which belayer is independent of the system.
2.5. Establish a belay that maintains safety of belayer and abseiler.
2.6. Position top rope or bottom brake belay away from hazards, or remove as able.
2.7. Determine need for, and establish, back up belay systems.
2.8. Complete safety checks according to organisational procedures.
|
|
3. Rig rope pitches for natural surface abseils.
|
3.1. Rig ropes to minimise effects of rope stretch and rub points and to allow efficient descent and ascent.
3.2. Set up anchors and ropes to allow for a rescue.
3.3. Select and tie knots suitable for system type established.
3.4. Minimise risk of cross loading and mis-alignment of carabiners.
3.5. Verify manufacturers' recommendations, equipment limitations and safety margins, and rig equipment accordingly.
3.6. Rig to minimise impact on the natural environment.
3.7. Complete safety checks according to organisational procedures.

Performance Evidence
Evidence of the ability to complete tasks outlined in elements and performance criteria of this unit in the context of the job role, and:
- select and set up belay systems and ropes suitable for single pitch abseils at three different natural pitches
- collectively set up the following types of systems:
- single rope
- releasable abseil line
- rope systems suitable for single rope techniques
- top rope top belay
- bottom brake belay
- self-belay
- collectively select and use these different types of anchors:

- collectively select and tie at least four different types of knots suitable for the system type established, and appropriate for the intended load and function
- identify and tag three different types of faulty equipment.
Knowledge Evidence
Demonstrated knowledge required to complete the tasks outlined in elements and performance criteria of this unit:
- organisational procedures for safety and serviceability checks
- how the following factors affect selection of descent and ascent routes for natural surfaces including:
- season of operation, weather and environmental conditions
- participant characteristics including age, size, weight, fitness and abseiling skill level
- group objectives and size
- environmental hazards specific to abseiling on natural surfaces and how these affect:
- safe access to and egress from the pitch
- choice of descent and ascent routes for safety of abseiler
- positioning of top or bottom belay systems for safety of belayer
- features, functions, advantages and disadvantages of different types of anchors used for abseiling on natural surfaces including:
- threads
- bolts
- chains
- concrete bollards
- spring loaded camming devices
- nuts, wires and hexes
- pitons
- issues that are assessed when selecting anchors and likely impacts of poor condition on performance under load:
