Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Implement dismantling of trees

  1. Communicate with work team during operations, as required, verbally, using hand signals and whistles
  2. Calculate mass of tree section, balance of load and confirm mass does not exceed safe working limit of equipment
  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
  4. Use and control friction devices as required
  5. Dismantle branches and trunk sections using the 'cut and drop' method, and cut and lower by ropes and other lowering devices
  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
  7. Use and control elevated work platforms as required
