Elements and Performance Criteria

RANGE STATEMENT
9)This relates to the unit as a whole providing the range of contexts and conditions to which the performance criteria apply. It allows for different work environments and situations that will affect performance.
This unit shall be demonstrated in relation to carrying out work activities in a gas industry work environment with a potentially hazardous area or confined space to locate and pin point gas escapes.
The following constants and variables included in the element/performance criteria in this unit are fully described in the Volume 2, Part 2.1.
Appropriate persons
Safe working procedures
Legislative requirements
Personal Protective Equipment

EVIDENCE GUIDE
8) This provides essential advice for assessment of the unit and must be read in conjunction with the performance criteria and the range statement of the unit and the Training Package Assessment Guidelines.
The Evidence Guide forms an integral part of this unit. It must be used in conjunction with all components parts of this unit and performed in accordance with the Assessment Guidelines of this Training Package.

Overview of Assessment
8.1)
Longitudinal competency development approaches to assessment, such as Profiling, require data to be reliably gathered in a form that can be consistently interpreted over time. This approach is best utilised in Apprenticeship programs and reduces assessment intervention. It is the industry-preferred model for apprenticeships. However, where summative (or final) assessment is used it is to include the application of the competency in the normal work environment or, at a minimum, the application of the competency in a realistically simulated work environment. It is recognised that, in some circumstances, assessment in part or full can occur outside the workplace. However, it must be in accord with industry and regulatory policy.
Methods chosen for a particular assessment will be influenced by various factors. These include the extent of the assessment, the most effective locations for the assessment activities to take place, access to physical resources, additional safety measures that may be required and the critical nature of the competencies being assessed.
The critical safety nature of working with electricity, electrical equipment, gas or any other hazardous substance/material carries risk in deeming a person competent. Sources of evidence need to be 'rich' in nature to minimise error in judgment.
Activities associated with normal everyday work influence decisions about how/how much the data gathered will contribute to its 'richness'. Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practised. These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments. Sample assessment instruments are included for Assessors in the Assessment Guidelines of this Training Package.

Critical aspects of evidence required to demonstrate competency in this unit
8.2)
Before the critical aspects of evidence are considered all prerequisites shall be met.
Evidence for competence in this unit shall be considered holistically. Each element and associated performance criteria must be demonstrated on at least two occasions in accordance with the 'Assessment Guidelines - UEG11. Evidence shall also comprise:

A representative body of work performance demonstrated within the timeframes typically expected of the discipline, work function and industrial environment. In particular this shall incorporate evidence that shows a candidate is able to:

Implement Occupational Health and Safety workplace procedures and practices, including the use of risk control measures as specified in the performance criteria and range statement
Apply sustainable energy principles and practices as specified in the performance criteria and range statement
Demonstrate an understanding of the required knowledge and skills as described in this unit. It may be required by some jurisdictions that RTOs provide a percentile graded result for the purpose of regulatory or licensing requirements.
Demonstrate an appropriate level of skills enabling employment
Conduct work observing the relevant Anti-discrimination legislation, regulations, polices and workplace procedures

Demonstrated consistent performance across a representative range of contexts from the prescribed items below:

Use a portable gas detector to locate escape as described in 9) and including:


A
Following work permits/authorisations and clearance procedures.


B
Monitoring gases and hazards and following evacuation procedures.


C
Determining whether the gas/vapour level in a work area is safe from explosive, toxic and oxygen deficiency aspects based on gas properties and environmental conditions.


D
Locating and pin pointing gas escapes


E
Following procedures to maintain the integrity of gas detectors


F
Identification of PPE required for conditions.


G
Applying relevant contingency management skills.

Context of and specific resources for assessment
8.3)
This unit should be assessed as it relates to normal work practice using procedures, information and resources typical of a workplace. This should include:
OHS policy and work procedures and instructions.
Suitable work environment, facilities, equipment and materials to undertake actual work as prescribed by this unit.
These should also be part of the formal learning/assessment environment.
Note:
Where simulation is considered a suitable strategy for assessment, conditions must be authentic and as far as possible reproduce and replicate the workplace and be consistent with the approved industry simulation policy.

The resources used for assessment should reflect current industry practices in relation to using portable gas detectors.

Method of assessment
8.4)
This unit shall be assessed by methods given in Volume 1, Part 3 'Assessment Guidelines'.
Note:
Competent performance with inherent safe working practices is expected in the Industry to which this unit applies. This requires assessment in a structured environment primarily intended for learning/assessment which incorporates all necessary equipment and facilities for learners to develop and demonstrate the required knowledge and skills described in this unit.

Concurrent assessment and relationship with other units
8.5)
For optimisation of training and assessment effort competency development in this unit may be arranged concurrently with the following units:
UEGNSG132A
Carry out basic work activities in a gas industry work environment
