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.

Pre-requisite Unit

AHCARB311 Tie, dress, set and finish arborist knots

Unit Sector

Arboriculture (ARB)

The candidate must demonstrate knowledge of:

  • work zone
  • first aid, emergency personnel, equipment and procedures
  • work health, safety, site, environmental and traffic control measures
  • tree examination
  • observation of tree defects
  • rigging equipment

Assessment Conditions

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
