Elements and Performance Criteria

  1. Select and prepare hand tools
  2. Operate hand tools underwater
  3. Maintain hand tools

Evidence Required

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 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 divers vocational focus

Specific resources for assessment

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