Elements and Performance Criteria

1. Prepare to use portable gas detection device.
   • The need to initiate gas detection is identified by WHS/OHS requirements and established procedures.
   • The gas or vapour to be detected is established from maps and asset records or consultation with relevant personnel.
   • Gas detection device(s) for the gas/vapour to be detected is/are checked for calibration and response in accordance with manufacturer instructions.
   • Appropriate PPE is available and checked
   • Gas detection devices are checked for factors that could prevent the equipment from being used correctly and safely.
2. Use gas detectors and pin point escapes
   • WHS/OHS policies and procedures relating to gas/vapour detection are followed.
   • Gas detection device is used in accordance with manufacturer instructions and with regards to environmental conditions.
   • Gas detection readings are recorded in accordance with established procedures.
   • Probable areas that gases could accumulate are monitored dependant on Gas Properties and environmental conditions
   • Gas detector readings are interpreted correctly and converted to relevant % i.e. GIA to LEL etc.
   • Gas escapes are located and pin pointed in accordance with established procedures.
   • Required actions are determined and communicated to relevant persons in accordance with established procedures.
   • Environmental conditions are used to assist in location of gases
   • The frequency of monitoring is determined from the nature of gas/vapour and the effect of environmental and local conditions
3. Complete the use of gas detectors and relevant documentation.
   • Gas detection devices are purged, disassembled and stored in accordance with manufacturer recommendations.
   • Gas detection devices are formally checked and calibrated periodically in accordance with established site requirements and instrument accuracy.
   • Storage, use and calibration record of the gas detection devices is maintained, in accordance with the established procedures.
   • Appropriate persons are notified of completion of the work
   • Reports and documentation are completed with readings accurately recorded and maintained for potential use as evidence in accordance with company procedures.

Evidence Required

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

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 industrypreferred 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 substancematerial 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 howhow 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	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 UEG 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 Antidiscrimination 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 and including
		A	Following work permitsauthorisations and clearance procedures
		B	Monitoring gases and hazards and following evacuation procedures
		C	Determining whether the gasvapour level in a work area is safe from explosive toxic and oxygen deficiency aspects based on gas properties and environmental conditions

		F	Identification of PPE required for conditions
		G	Applying relevant contingency management skills

Context of and specific resources for assessment

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 learningassessment 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

This unit shall be assessed by methods given in Volume Part 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 learningassessment 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
