Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following

carry out and record preoperational and safety checks

conduct a site and tree hazard identification and risk control assessment

inspect a tree and determine safest and best work method using risk controls established

select inspect and prepare ropes harnesses and other equipment associated with climbing trees

safely climb ascend and descend large hazardous and complex trees using a number of anchor points

climb using documented safe work methods

inspect for faults and store ropes harnesses and other climbing and safety equipment and replace if worn or faulty

document the hazards identified and the risk controls selected

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances


Range Statement

The range statement relates to the unit of competency as a whole.

Situations may include:

complex tree climbing incorporates situations made hazardous by tree branches vulnerable to failure under a load

trees affected by decay, disease and/or pests, trees with embedded objects such as wire, nails or spikes

proximity of power lines

adjacent property or intruding branches

the tree's height, size, trunk characteristics, shape and weight distribution of the crown may contribute to making conditions hazardous to a climber or a felling or trimming operation

inclement weather may also contribute to making working conditions difficult and hazardous.

Climbing tools and equipment may include:

ropes

safety harnesses

ascending and descending devices

ladders

safety equipment (helmets, ear and eye protection, gloves, boots, etc.)

pulleys and blocks

shackles and karabiners.
