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!

PUADEFDV010B - Employ power tools in an underwater environment

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

Prepare to use power tools underwater

Work task, worksite data and work object are determined and analysed to determine the specific requirements for power tools
Work plan is developed consistent with the dive plan
Power tools and protective equipment are selected, inspected and prepared
Compressor and associated leads and hoses are selected, inspected and prepared
Power tools, compressor, and associated leads and hoses are secured safely to/from the dive site
Access obstructions and other hazards are assessed and action is taken to remove/reduce the risk
Occupational health and safety (OH&S) requirements and recognised safety precautions are applied in accordance with standard procedures, manufacturers' instructions and legislation

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

consider the environmental impact as part of the dive plan

lift either:

air – clear mud from hole of half a cubic metre or

water – clear mud from hole of half a cubic metre

operate any four of the following:

power wrench, including changing sockets on site; tightening and loosening nuts

drill, including drilling a hole in steel plate; changing bits on site

disc cutter, including cutting steel or concrete; changing disc on site

jack hammer, including breaking concrete

chainsaw, including cutting wooden beams 230 x 100 mm

angle grinder, including cleaning and smoothing a fillet; chamfering a 12 mm plate; changing disc on site

scrubber, including cleaning 2 m2 of horizontal and vertical surface

operate a pneumatic or hydraulic compressor including:

connecting hoses and leads

connecting to the power supply

adjusting output power

switching the compressor on/off.

Consistency in performance

Competency should be demonstrated during a number of work tasks using the power tools outlined in the Critical Aspects of Evidence.

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; power tools; and compressor, leads and hoses.

Guidance information for assessment

Information that will assist or guide assessment will be written during Phase II of the Review of the PUA00 Public Safety Training Package.

Required Skills and Knowledge

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

Required Skills
