An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.
There must be evidence that the individual has installed three different types of tree support systems according to a specification, including:
steel cable
textile or synthetic cable
bracing.
There must also be evidence that the individual has:
interpreted plans and specifications and determined the materials, tools and equipment required for tree support system work
identified health, safety and environmental hazard and risks and implemented controls for the installation, including:
conducted and completed a job safety analysis (JSA)
prepared and used personal protective equipment (PPE)
maintained awareness of above-ground hazards while performing work
assembled tree support system ready for installation
examined structural integrity of the tree
determined and confirmed the safest access to location of the tree support system
pruned tree to aid tree support system installation
accessed the tree safely and secured into work position
removed, checked, maintained, cleaned, sanitised and stored tools and equipment according to biosecurity procedures
recorded and reported completed works.
All tree support systems work is required to be performed according to preferred industry practices (as outlined in the Companion Volume).

arboriculture hygiene and biosecurity standards
specifications for the installation of tree support system for specific tree defects
relationships:
work team.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards. In particular, assessors must have:
arboriculture vocational competencies at least to the level being assessed
current arboriculture industry skills directly relevant to the unit of competency being assessed.
