PUADEFDV008B Employ hand tools in an underwater environment

Modification History

Not applicable.

Unit Descriptor

Unit Descriptor	This unit covers the competency required to use hand tools in an underwater environment. The unit also includes selecting the appropriate hand tools for the work task and inspecting them for serviceability. The diver must ensure the tools are secured on own body throughout the dive, and correctly employ the tools during the work task, with particular attention to safety. The diver will be responsible for the recovery of any waste arising from the work task. Finally, the hand tools 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.

Application of the Unit

Application of the Unit	The application of this unit in the workplace - the environments, complexities and situations involved - will be written during Phase II of the Review of the PUA00 Public Safety Training Package. This text will be useful for the purposes of job descriptions, recruitment advice or job analysis; where possible, it will not be too job specific to allow other industries to import it into other Training Packages, where feasible.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a Unit of Competency.	Performance Criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the Required Skills and Knowledge and/or the Range Statement. Assessment of performance is to be consistent with the Evidence Guide.

Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Select and prepare hand tools	1.1 Work task and worksite data are determined and analysed to determine the specific requirements for hand tools 1.2 Work plan is developed consistent with the dive plan 1.3 Hand tools and protective equipment are selected, inspected and prepared 1.4 Hand tools are secured safely to/from the dive site 1.5 Access obstructions and other hazards are assessed and action is taken to remove/reduce the risk 1.6 Occupational health and safety (OH&S) requirements and recognised safety precautions are applied in accordance with standard procedures, manufacturers' instructions and legislation
2. Operate hand tools underwater	2.1 Hand tools are secured on self during the dive for ease of accessibility and lack of interference with mobility and dive equipment 2.2 Work-safe area is established and the location and safety of divers is confirmed prior to commencing work task/s 2.3 Hand tools are employed underwater ensuring management of their associated hazards
3. Maintain hand tools	3.1 Environmental impact arising from use of hand tools is minimised and waste products are recovered 3.2 Hand tools and protective equipment are de-serviced after use

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE
This describes the essential skills and knowledge and their level, required for this unit.
Required Skills
ability to dive employ hand tools identify requirement for hand tools maintain hand tools
Required Knowledge
care of tools dive equipment dive physics general occupational/diving safety awareness identification of tool faults oceanography relevant references and Australian Standards use of tools on land work hazards

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; 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 60 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 diver’s vocational focus. Specific resources for assessment Access to a complete range of diving, safety and accessory equipment; and hand tools.
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.
