Issue Date: April 2024


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 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)

Prerequisites

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

This unit contains employability skills.




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.

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.


Submission Requirements

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.

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
Lazy shot, cordage and bail-out cylinder are inspected and prepared. 
Lazy shot, cordage and bail-out cylinder are deployed and set at required depth for the decompression stop. 
Adjustment for subsequent decompression stops is consistent with the dive plan. 
Lazy shot, cordage and bail-out cylinder are de-serviced and stowed for re-use. 
Diver is assisted in fitting and inspecting dive equipment prior to undertaking the dive. 
Assistance is provided during the diver's entry into, and exit from, the water from a range of platforms. 
Diver's equipment is confirmed for fit and absence of leaks on entering the water. 
Diver's safety line is managed throughout the dive and all line signals between the diver and supervisor are interpreted and responded to. 
Diver's condition, position and progress are reported regularly and accurately to the supervisor. 
Diver is controlled from the surface during a poor visibility search. 
Diver is assisted in the removal and stowage of equipment.
