Canyoning, Introduction



Minimum Breaking Strength (MBS): is the magnitude of a load that may permanently distort or damage equipment but not cause it to break.

Multi-pitch: a section of a natural surface or artificial surface that to ascend, traverse or descend, progress is made by using more than one pitch and establishing belay systems mid route.


Natural surface(s): the geologic structure and flora that forms a cliff or steep face.

Non-actively participating: a participant that is waiting to but is not currently doing the activity.

Non-participating contact: a suitable person not involved in and not located with those conducting the activity, who is the nominated person to act on behalf of those undertaking the activity in accordance with the emergency management plan. This may include but is not limited to responsibility for alerting authorities on the failure of those undertaking the activity to report in as being safe or return on time.


Personal floatation device (PFD): See lifejacket.

Personal thermal protection: clothing worn to mitigate the effects of the temperature of the canyon environment.

Pitch: a section of a natural surface or artificial surface that requires no greater than one length of rope to ascend, traverse or descend. (Also see multi-pitch and single-pitch.)


Rappelling: see abseiling. Releasable rigging: a system where the abseil rope may be lowered in a controlled manner, even while weighted by a abseiler, by releasing part of the system.

Remote supervision: where a nominated person responsible for supervising others during all or part of the activity is not involved in direct or indirect supervision and is unlikely to be in the vicinity, and would therefore take time to respond (also see direct supervision and indirect supervision).

Responsible person: a competent person who is able to complete delegated elements or tasks during an activity that does not require the activity-specific competence of a leader or assistant leader.

River hazards: a hazard created by a watercourses’ geology and flora, the water within it or a combination of both. Common river hazards include but are not limited to: aerated water, drops, eddies, entrapment points, fast flowing water, floating objects, undercut rocks, re-circulations (also called ‘holes’), rapids, sieves, strainers, submerged objects etc. (Some hazards (e.g. eddies, re-circulations) are also known as hydraulics.)

Rock Climbing: ascending, traversing or descending vertical or near vertical natural surfaces. At times also used to describe climbing on artificial surfaces. (Also see climbing.)
