Application
This unit describes the performance outcomes, skills and knowledge required to abseil multi pitches on natural surfaces such as cliff face and cave pitches. It also requires the ability to belay abseilers and to self-belay.
It applies to leaders, guides or instructors who use these skills when leading participants during abseiling activities. Leadership skills are provided in complementary units.
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.

Elements and Performance Criteria

ELEMENTS

PERFORMANCE CRITERIA
|
|
Elements describe the essential outcomes
|
Performance criteria describe the performance needed to demonstrate achievement of the element.
|
|
1. Prepare for the abseil.
|
1.1. Select clothing, footwear and personal protective equipment suitable for the abseil and conditions.
1.2. Confirm activity safety and emergency response procedures to ensure compliance during activities.
1.3. Confirm protocols for communications between abseiler and belayer.
1.4. Interpret route description; identify position of natural features and the abseil route.
1.5. Attach descending device to abseil rope and tie knots suitable for the established belay system.
1.6. Complete equipment safety checks prior to abseiling or belaying.
|
|
2. Abseil using multi pitch descent techniques.
|
2.1. Use safety procedures at top of and throughout all descents to minimise risk to self and others present.
2.2. Use appropriate posture and abseiling techniques to execute descents to each station.
2.3. Safely approach, avoid or negotiate hazards to descend to stations in a controlled manner.
2.4. Maintain effective communication with belayer throughout all descents.
2.5. Retrieve ropes at bottom of each pitch, as last person down.
2.6. Use techniques that minimise damage to equipment and the surface during abseil.
|
|
3. Change over safely at belay stations.
|
3.1. Maintain continuous attachment to anchor points, traverse line or belay system.
3.2. Changeover personal equipment from one rope system to another at belay stations, tie suitable knots and handle ropes without entanglement.
3.3. Complete safety checks prior to loading belay system and before completing subsequent descents.
|
|
4. Belay abseilers during multi pitch descents.
|
4.1. Avoid or negotiate hazards and use safety procedures to minimise risk to self and others present.
4.2. Establish belaying position and attach self to anchor, as required, to allow effective and safe use of belay system.
4.3. Maintain rope tension to minimise fall distance and ensure abseiler movement is not unduly restricted.
4.4. Monitor abseiler progress constantly, and maintain clear communication with abseiler.
4.5. Arrest falls promptly using technique suitable to belaying device and situation.
4.6. Safely and efficiently secure abseiler using tie off techniques; release tie off and allow abseiler to continue.
|
|
5. Self-belay during multi pitch descents.
|
5.1. Attach self to suitable belay device for descent with back up to maintain safety in the event of a fall.
5.2. Use appropriate posture and abseiling techniques to execute self-belayed descents.
5.3. Control self-belay system to execute safe and controlled descents.
5.4. Utilise features of back up belay system in the event of a fall to self-arrest, self-rescue and complete descent.

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:
- complete the following multi pitch abseils on at least two different routes:
- a total of four descents with a belayer
- a total of three self-belayed descents with one of those descents as last person down using a doubled rope descent
- during each of the above abseils, consistently:
- follow safety procedures and safely negotiate hazards to descend in a controlled manner
- connect self to abseil and belay system using appropriate device and or knots
- complete two additional self-belayed descents, simulating a self-arrest and self-rescue to complete the descent
- belay abseilers according to safety procedures, and complete the following:
- three top rope, top belayed descents
- one bottom braked descent
- two simulated abseiler falls, and safely and efficiently secure and release abseilers to continue.
