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.

This unit covers the competency required to act as a lazy shot/bail-out operator and diver's attendant in an open water environment.

The lazy shot/bail-out operator's purpose is to mark the required decompression depth (through the use of the lazy shot) for ascending divers to service their decompression requirements. As part of the lazy shot rig, additional supplies of air (bail-out cylinders) are provided in the event that divers' personal supplies expire prior to surfacing. This can occur when multiple and/or lengthy decompression periods must be served.

The diver's attendant covers all aspects of assistance given to a diver in preparation for the dive, the conduct of the dive (such as management and monitoring of safety/communications lines) and the post-dive refurbishment of equipment.

Note: This unit covers the Australian Diver Accreditation Scheme (ADAS) occupational groupings of lazy shot/bail-out operator and diver's attendant in an open water environment. 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)

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 rig and set lazy shot and bailout at appropriate depth/s; to maintain communications; and to maintain attention to the diver throughout the dives. Consistency in performance Competency should be demonstrated over a variety of tasks including: transmitting at least two messages from the supervisor to the diver relaying at least two messages from the diver to the supervisor controlling a searching diver, at a minimum, in poor visibility (less than 2 metres) for 4 legs of 25 metres (e.g. parallel search).
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; lazy shot and bailout equipment; and a dive platform.
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.

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.

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
