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!

DEFDV015B - Employ explosive power tools in an underwater environment

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

Prepare to use EPT underwater

  1. Work task and worksite data are determined and analysed to determine the specific requirements for EPT.
  2. Work plan is developed consistent with the dive plan
  3. EPT, explosive charges and protective equipment are selected, inspected and prepared.
  4. EPT and explosive charges 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.

Operate EPT underwater

  1. EPT and explosive charges are secured on self for ease of accessibility and lack of interference with mobility and dive equipment.
  2. Material or base set out intended for explosive fasteners complies with detailed drawings and specifications.
  3. EPT attachments are installed and EPT charges are chambered.
  4. Work-safe area is established and the location and safety of divers is confirmed prior to commencing work task/s.
  5. EPT are operated underwater ensuring management of their associated hazards.
  6. EPT are cleared and rendered safe to evaluate the work task.
  7. Fastener penetration is checked for angle, depth and integrity of base.

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; to consider the environmental impact as part of the dive plan; and to focus on the integrity of the fasteners in performing the intended role.

Consistency in performance

Competency should be demonstrated during a number of work tasks where the diver fires a minimum of two charges over, at a minimum, two underwater work tasks into concrete, masonry or steel.

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.

Assessment should be conducted over a time frame that allows for the safe demonstration of competency.

Specific resources for assessment

Access to a complete range of diving, safety and accessory equipment; EPT and charges.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level, required for this unit.
