Unit of Competency AHCARB207 - Perform ground based rigging
Description
Employability Skills
Learning Outcomes and Application This unit of competency describes the skills and knowledge required to perform ground based rigging. This unit does not cover crane operations.The unit applies to ground based workers who undertake defined activities with specialised tools and methods, work in structured and changing contexts, apply knowledge and skills to demonstrate autonomy and limited judgement, and provide solutions to a limited range of predictable problems. Work is implemented with low risk work procedures and to comply with Safe Work Method Statement documentation.Licensing, legislative, regulatory, or certification requirements apply to this unit in some states and territories at the time of publication, and may differ according to jurisdiction. Specific determination should be sought through the relevant State or Territory. Works involving this unit of competency may be subject to local tree protection and preservation laws, and the relevant content of applicable Australian Standards.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessment must be demonstrated consistently over time in a suitable range of contexts and have a productivity-based outcome. No single assessment event or report is sufficient to achieve competency in this unit.

Assessment may be conducted in a simulated or real work environment, however determination of competency requires the application of work practices under work conditions.

The mandatory equipment and materials used to gather evidence for assessment include:

equipment:

rigging equipment

static and dynamic rope kit

harness

lowering and friction devices

high decibel whistle

personal protective equipment (PPE)

first aid and emergency kit

rescue kit

traffic management kit

signage – work zone

trees

materials:

rigging operations form - ground based

hazard identification and risk control form

equipment and PPE check form

emergency preparation form

site assessment form

tree recognition form

work communications form

work site operations form

Assessors must satisfy current standards for RTOs in the assessment of arboriculture units of competency.

Assessment must be conducted only by persons who have:

arboriculture vocational competencies at least to the level being assessed

current arboriculture industry skills directly relevant to the unit of competency being assessed
