As agreed in the creation of this Training Package, applications for units transferred from the PUA00 Public Safety Training Package will be developed as part of continuous improvement plans, and taking into account the change in Unit of Competency format as detailed in templates for Streamlined Training Packages

This unit covers the competency required to employ explosive power tools (EPT) in an underwater environment.

The unit also include selecting the appropriate EPT for the work task and inspecting them for serviceability. The diver must ensure the EPT are secure on own body throughout the dive, and correctly operate the EPT during the work task, with particular attention to safety during firing.

The diver will be responsible for the recovery of any waste arising from the work task to ensure the preservation of the environment. Finally, the EPT must be de-serviced and stored appropriately for ongoing use.

Note: This Unit of Competency relates, in part, to the existing standards of the Australian Diver Accreditation Scheme (ADAS). All information was correct at the time of development of this Unit of Competency; however, any diver seeking ADAS accreditation should consult ADAS and not rely on the information contained in this unit.

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

DEFDV001B Dive using self contained underwater breathing apparatus in open water to 30 metres.

DEFDV008B Employ hand tools in an underwater environment.

This unit contains employability skills.

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.

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.

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

(add new lines for each of the assessment tasks)

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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

The Range Statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording in the Performance Criteria is detailed below.
Work task may include	fastening
Worksite data may include::	composition of base (refer below for types of base) condition of base current depth gradient hazards obstacles
EPT may include:	direct action indirect action
Protective equipment may include:	boots ear protection gloves
Selecting, inspecting and preparing EPT, explosive charges and protective equipment may include:	date checks reviewing equipment logs visual inspection
Action to remove/reduce the risk may include:	erecting signage using patrol/sentry craft
Material or base may include:	concrete masonry steel
EPT attachments may include:	channel rebate
Operation of EPT may include:	loading firing misfire procedures
Hazards may include:	fall zone of objects being worked on impact of ept on dive equipment (e.g. hoses, gauges, communications) operational zone and danger area of ept release of fuels and associated chemical contaminants resident at the worksite
Environmental impact may include:	contamination of surrounding water (e.g. leaking oil) physical damage to reef and associated floor eco-systems (e.g. coral) visual pollution of waste material (e.g. concrete and metal parts)
De-servicing may include:	drying logging work details into equipment logs oiling/greasing washing in fresh water

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice	Yes	No	Comments/feedback
Work task and worksite data are determined and analysed to determine the specific requirements for EPT.
Work plan is developed consistent with the dive plan
EPT, explosive charges and protective equipment are selected, inspected and prepared.
EPT and explosive charges are secured safely to/from the dive site.
Access obstructions and other hazards are assessed and action is taken to remove/reduce the risk.
EPT and explosive charges are secured on self for ease of accessibility and lack of interference with mobility and dive equipment.
Material or base set out intended for explosive fasteners complies with detailed drawings and specifications.
EPT attachments are installed and EPT charges are chambered.
Work-safe area is established and the location and safety of divers is confirmed prior to commencing work task/s.
EPT are operated underwater ensuring management of their associated hazards.
EPT are cleared and rendered safe to evaluate the work task.
Fastener penetration is checked for angle, depth and integrity of base.
Environmental impact arising from use of EPT is minimised and waste products are recovered.
EPT and protective equipment are de-serviced after use.
Explosive charge usage is documented.
