Overview of assessment

Competency in this unit underpins competency in other aspects of the candidate's role in managing work tasks.

This unit could be assessed on its own or in combination with other units of competency relevant to the job function.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

A person who demonstrates competency in this unit must be able to provide evidence of:

locating, interpreting and applying relevant information, standards and specifications

complying with site safety plan, OHS regulations and ODS and SGG regulations (where required) and state and territory legislation applicable to workplace operations

complying with organisational policies and procedures, including quality requirements

communicating and working effectively and safely with others

in a minimum of two different settings:

identifying risk reduction measures

identifying system components and materials

identifying, selecting and using tools, equipment and materials to perform decommissioning procedures on installed gaseous agent containers and actuation devices

identifying potential risks and hazards

reviewing decommissioning guidelines with relevant person(s)

adhering to safety procedures during decommissioning procedures

decommissioning installed gaseous agent containers and actuation devices using decommissioning guidelines

creating appropriate records and documentation

completing workplace housekeeping requirements.

Specific resources for assessment

Resource implications for assessment include access to:

actual or simulated work environment and installed gaseous agent containers and actuation devices

decommissioning guidelines and procedures

assessment documentation, including training and assessment record books

all necessary tools, specialist equipment, materials and spare parts

relevant manuals and other documentation, including Australian standards.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oracy, language and literacy capacity of the candidate and the work being performed.

Context of assessment

For valid and reliable assessment of this unit, competency should be demonstrated over a period of time and be observed by the assessor (or assessment team working together to conduct the assessment).

Competency is to be demonstrated in a range of situations, reflecting the practical requirements of the workplace which may include customer and workplace interruptions and involvement in related activities normally experienced in the workplace.

Assessment of competency over the full range of performance criteria may be made through practical demonstrations in the workshop environment. Consideration should be given to assessing consistency of outcome over an appropriate period of time.

Candidates should also be given the opportunity to practise and undertake self-assessment of performance before requesting formal assessment.

All safety requirements must be adhered to during all practical activities.

Oral questioning or a written assessment may be used to assess underpinning knowledge. (Inassessment situations, where the candidate is offered a preference between oral questioning and written assessment, questions are to be identical.)

Assessment of evidence should establish the candidate's ability to perform the job to the standard required in the workplace.

Supplementary evidence may be obtained from relevant authenticated correspondence or reports from supervisors or team leaders that demonstrates an understanding of the requirements for decommissioning installed gaseous agent containers and actuation devices.

Candidate should be encouraged to compile a portfolio of examples of completed documentation relevant to the candidate's organisation. One accurate example of each completed document is suggested as sufficient to infer competency and ability to transfer appropriate skills to each document type when required in the workplace. (Oral questioning may contribute as evidence of this ability.)

Information derived from enterprise policies and practices must be treated as commercial-in-confidence.

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge.

Questioning will be undertaken in such a manner as is appropriate to the oracy, language and literacy levels of the candidate and any cultural issues that may affect responses to the questions. It will reflect requirements of the unit of competency and the work being performed.

Where assessment is for the purpose of recognition (RCC or RPL), the evidence provided will need to be authenticated and show that it represents current competency demonstrated over a period of time.
