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!

DEFEXO111 - Conduct underwater explosive demolitions

What evidence can you provide to prove your understanding of each of the following citeria?

Prepare for underwater demolitions

  1. Analyse work task and worksite data to determine the specific requirements for the explosive demolition.
  2. Develop a work plan consistent with the dive plan.
  3. Select, inspect and prepare explosives, associated equipment and protective equipment.
  4. Secure explosives and associated equipment to/from the dive site.
  5. Assess access obstructions and other hazards and take action to remove/reduce the risk.
