Range Statement
Performance Evidence
The candidate must be observed climbing trees using standard climbing techniques in a safe manner. The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.
The candidate must provide evidence for and demonstrate:appropriate method for accessing tree – climbing or using an EWP – through discussion with work teamdetermining location of above-and-below-ground servicesundertaking a site-specific risk assessment by identifying work health and safety hazards and assessing riskconfirming first aid and rescue personnel, equipment and procedures ensuring work team member present, capable, willing and equipped to assist or perform aerial rescue operationspreparing and carrying out pre-operational and safety checks, on ropes, harnesses, tools and equipmentselecting and using personal protective equipment and safety equipmentrecording and implementing work health, safety, site, environmental and traffic control measuresselecting harness and appropriate equipment for climbinginspecting tree to determine low risk access route through discussion with work team and seek feedbackestimating tree height and load in relation to safe working limits of ropes and equipmentdetermining the hold, release and grip attributes of ropeselecting and using dynamic ropeselecting and using triple locking carabinerstying, dressing, setting and finishing climbing knots and hitchescommunicating with work team during operations using voice, hand and whistle signalsmaintaining awareness of power line clearancesselecting low risk anchor points in accordance with strength, suitability requirements and branch weightaccessing and ascending tree using low risk access route with harness and lanyard ascending using double rope with prussik techniqueascending using trunk walking technique and foot ascenders as requireddescending tree in a controlled mannerremoving all access equipment in a controlled mannercleaning and storing climbing equipmentcleaning and storing personal protective equipmentuse of industry standard-terminology to describe climbing and the work environment.
