Employ explosive power tools in an underwater environment

Assessment tool

Version 1.0
Issue Date: April 2024


This unit specifies the skills and knowledge required to employ explosive power tools (EPTs) in an underwater environment.

It includes preparing and selecting an appropriate EPT for underwater work task and inspecting it for serviceability. It also includes recovering waste, and deservicing and storing of equipment.

This unit applies to persons working as Defence Divers or to others working in this field.

The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.

Persons undertaking this unit work independently and perform specific tasks in a range of contexts that could be unpredictable.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or other simulations

relevant and appropriate materials, explosive power tools, equipment and personal protective equipment currently used in industry

ocean with a range of oceanic, diurnal and nocturnal environments

applicable documentation including organisational procedures, regulations, codes of practice and operation manuals.

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