It is an industry requirement that delivery of training and assessment in this unit provides for the explicit conditions of work team capability for aerial rescue operations. It is an industry requirement for competency in this unit that assessment must include a log record of two hundred (200) hours of advanced climbing.
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:
single rope technique (SRT) climbing kit
harness
chaps
climbing friction hitches
high decibel whistle
personal protective equipment (PPE)
first aid and emergency kit
rescue kit
traffic management kit
trees
materials:
climbing techniques form - advanced
climbing log record – advanced
tree inspection form
hazard identification and risk control form
equipment and PPE check form
knot identification form
work communications form
rescue form - aerial
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
