Elements and Performance Criteria

1. Prepare for tree removal
   • Trees are assessed for size, structural defects, weight distribution, spread/width, wind loading and canopy.
   • The fall site is assessed considering wind speed and direction, topography, safe fall zone, exclusion zone, any potential danger to the public or property, and environmental implications.
   • Tools, equipment and machinery are selected according to appropriate removal methods.
   • Pre-operational and safety checks are carried out on tools, equipment and machinery according to manufacturers specifications and enterprise guidelines.
   • OHS hazards are identified, risks assessed and risk controls are implemented.
   • Risk controls selected determine work method to cut and drop, or use rigging techniques.
   • Suitable safety equipment and Personal Protective Equipment (PPE) is selected, used and maintained.
2. Coordinate site preparation
   • A safe fall zone and exclusion zone are determined considering tree characteristics, degree of lean of tree, and site, environmental, and safety assessments.
   • A planned escape route, noting debris and other potential hazards is determined.
   • Fall zone and escape route are cleared and surrounding features/structures are protected from damage.
   • Exclusion zone is identified, appropriate safety barriers erected and safety procedures implemented and monitored.
3. Dismantle branches
   • Weights of tree branches are ascertained so that they do not exceed the safe working limit of equipment.
   • Branches are dismantled using the "cut and drop" method, or cut and lowered by ropes in accordance with accepted rigging techniques.
   • Dismantling techniques are employed to ensure branches fall or are lowered safely into the determined drop zone with no damage to property and equipment, or injury to personnel.
4. Dismantle tree
   • A safety lanyard and climbing spurs are used to ascend tree to perform sectional felling.
   • An elevated platform is used for access to assist sectional felling.
   • Sections are cut and thrown using a directional scarf and back cut with an accepted industry method.
   • Sections are cut and dropped using a horizontal cut and appropriate hinge wood.
   • A pull rope is used to control fall of tree sections.
   • Industry standard hitches and knots are used in rope lowering of cut tree sections.
5. Fell wind thrown and suspended trees
   • The risk potential of wind thrown or suspended tree is assessed.
   • Safe work methods which apply to the removal of wind thrown or suspended trees are adopted.
   • Hand or power winches are used to pull out the suspended tree as necessary.
   • The root system of a wind thrown tree lying on the ground is propped.
   • Wind thrown tree is crosscut in correct position to reduce trunk movement and prepare it for removal.
6. Complete felling operations
   • Felled trunks and branches are crosscut and trimmed to manoeuvrable lengths ready for disposal.
   • The site is cleared of trunk, branches and tree debris.
   • Timber disposal methods and equipment are used in accordance with the manufacturer's specifications and documented low risk work procedures.

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 conduct a site and tree hazard identification and risk control assessment prepare materials and equipment to specifications set up safe fall and exclusion zones use low risk dismantling procedures to fell a tree fell wind thrown and suspended trees use documented low risk work procedures record worksite activities according to documented guidelines
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
