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!

DEFDV008B - Employ hand tools in an underwater environment

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

Select and prepare hand tools

  1. Work task and worksite data are determined and analysed to determine the specific requirements for hand tools.
  2. Work plan is developed consistent with the dive plan.
  3. Hand tools and protective equipment are selected, inspected and prepared.
  4. Hand tools are secured safely to/from the dive site.
  5. Access obstructions and other hazards are assessed and action is taken to remove/reduce the risk.
  6. Work health and safety (WHS) requirements and recognised safety precautions are applied in accordance with standard procedures, manufacturers' instructions and legislation.

Operate hand tools underwater

  1. Hand tools are secured on self during the dive for ease of accessibility and lack of interference with mobility and dive equipment.
  2. Work-safe area is established and the location and safety of divers is confirmed prior to commencing work task/s.
  3. Hand tools are employed underwater ensuring management of their associated hazards.

Instructions to Assessors

Evidence Guide

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to attend to personal and collective safety; and to consider the environmental impact as part of the dive plan.

Consistency in performance

Competency should be demonstrated during a number of work tasks where the diver employs not less than four different hand tools in underwater work tasks for a total usage time of not less than 60 minutes.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the ocean supported by questioning on shore or aboard vessels.

When practicable, assessment should relate to the diver’s vocational focus.

Specific resources for assessment

Access to a complete range of diving, safety and accessory equipment; and hand tools.
