Application
This unit describes the performance outcomes, skills and knowledge required to select and set up belay systems and ropes suitable for abseils in intermediate to advanced canyons, 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.

3.1. Rig ropes to minimise effects of rope stretch and rub points and to allow efficient descent and ascent.
3.2. Rig retrievable abseil systems suitable for the top rope or bottom brake belay requirements.
3.3. Set up anchors and ropes to allow for a rescue.
3.4. Select and tie knots suitable for system type established.
3.5. Minimise the risk of cross loading and mis-alignment of carabiners.

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 canyoning environments:
- 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 in canyons 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 in canyons:
- threads
