Application
This unit of competency describes the skills and knowledge required to dismantle trees in confined spaces and in difficult or hazardous circumstances.
This unit applies to individuals who have a range of skills to select and apply a specialised range of methods, tools, materials and information to complete routine activities and provide and transmit solutions to predictable and sometimes unpredictable problems. Discretion and judgement is required. The work requires the application of extensive arboricultural knowledge. 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.

Performance criteria |
Elements describe the essential outcomes. |
Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare for tree removal |
1.1 Determine access to site and gain approval by owner or site management 1.2 Confirm site preparations, including notification of local residents and authorities where necessary 1.3 Determine location of above-and-below-ground services 1.4 Undertake a site-specific risk assessment by identifying work health and safety hazards and assessing risk 1.5 Protect, relocate and secure assets, property and vegetation related to work zone activities from potential damage during tree removal 1.6 Inspect trees to determine dimensions, appropriate removal methods and to confirm appropriateness of selected risk controls 1.7 Determine drop zone and communicate to all personnel 1.8 Confirm first aid, rescue personnel, equipment and procedures applicable to tree work 1.9 Carry out pre-operational and safety checks on tools, equipment and machinery 1.10 Select and use personal protective equipment 1.11 Record and implement work health, safety, site, environmental and traffic control measures |
2. Implement dismantling of trees |
2.1 Communicate with work team during operations, as required, verbally, using hand signals and whistles 2.2 Calculate mass of tree section, balance of load and confirm mass does not exceed safe working limit of equipment 2.3 Use dismantling techniques to ensure branches and trunk sections fall or are lowered safely into determined drop zone, with no damage to property and equipment or injury to personnel 2.4 Use and control friction devices as required 2.5 Dismantle branches and trunk sections using the 'cut and drop' method, and cut and lower by ropes and other lowering devices 2.6 Use directional felling techniques to ensure trunk of dismantled tree falls safely into determined drop zone with no damage to property and equipment or injury to personnel 2.7 Use and control elevated work platforms as required |
3. Complete tree removal |
3.1 Reduce dismantled tree sections to manoeuvrable lengths 3.2 Remove plant material and debris from site 3.3 Clean and check tools, equipment and machinery, and store 3.4 lean and store personal protective equipment 3.5 Record completion of tree removal and report to owner or site manager |
