Required Skills
Required skills |
communication skills to: communicate with others to ensure safe and effective work practices confirm job specifications and client requirements enable clear and direct communication, using questioning to identify and confirm requirements, share information, listen and understand use language and concepts appropriate to cultural differences use and interpret non-verbal communication, such as hand signals literacy skills to: prepare documentation, including: operation and maintenance manual plans, specifications and schedules read and interpret: documentation from a variety of sources plans, specifications, drawings and design briefs standards and manufacturer requirements and manuals statutory and regulatory requirements initiative and enterprise skills to develop creative and responsive approaches numeracy skills to apply measurements and calculations planning and organising skills to: research, collect, organise and understand information relating to the design of industrial gas systems take initiative and make decisions problem-solving skills to analyse requirements, consider options and design an appropriate system teamwork skills to work with others to action tasks and relate to people from a range of cultural and ethnic backgrounds and with varying physical and mental abilities technical skills to design industrial gas systems and components in compliance with IEC requirements |
Required knowledge |
application of: Australian standards, including AS5601 (AG601) Gas installations manufacturer specifications, including hazards identified in relation to devices and systems used other codes or standard operating procedures state regulatory authorities’ requirements common terminology and definitions used in the design of industrial gas systems principles of technology in the design of industrial gas systems workplace safety requirements, including relevant statutory regulations, codes and standards |
Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | This unit of competency could be assessed in the workplace or a close simulation of the workplace environment providing that simulated or project-based assessment techniques fully replicate plumbing and services workplace conditions, materials, activities, responsibilities and procedures. |
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: evaluating and documenting design parameters, including: client Gas Act 1965 and amendments manufacturer and Australian and New Zealand standard requirements for a range of industrial gas systems regulatory planning and detailing system components, including: burners controls regulators designing and sizing industrial gas systems preparing plans for a range of industrial gas systems to industry standards preparing specifications for industrial gas systems preparing testing and commissioning schedules producing operation and maintenance manuals. |
Context of and specific resources for assessment | This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian standards’ requirements. Resource implications for assessment include: an induction procedure and requirement realistic tasks or simulated tasks covering the minimum task requirements relevant specifications and work instructions, including design brief drawings, specifications, codes, design concepts and construction schedules tools and equipment appropriate to applying safe work practices, including computers, software and calculators workplace instructions relating to safe working practices and addressing hazards and emergencies material safety data sheets research resources, including industry-related systems information. Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. |
Method of assessment | Assessment methods must: satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application reinforce the integration of employability skills with workplace tasks and job roles confirm that competency is verified and able to be transferred to other circumstances and environments. Validity and sufficiency of evidence requires that: competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence. Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
