Description
This unit involves the skills and knowledge required to prepare safe design specifications of a gas system.It includes identifying safe system/installation design specifications, preparing gas system input and output performance criteria, and assessing environment impact of gas the system. It also includes identifying and evaluating gas system options, and preparing system specifications for natural or liquefied petroleum gas (LPG).This unit applies to safe work site where gas industry operations occur. It could also apply, where applicable, to other workplaces in the electricity supply industry (transmission and distribution and generation), the electrotechnology industry and the water industry, subject to work health and safety (WHS)/occupational health and safety (OHS) and duty of care requirements being met for the workplace.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Prepare gas systeminput and output performance criteria
  • 1.1 WHS/OHS principles and practices and environmental and sustainable energy workplace procedures which may influence the systems are reviewed and determined
  • 1.2 Proposed gas system usage is analysed and technical requirements of the system are investigated and expected outcomes of design work are confirmed with the appropriate persons
  • 1.3 Organisational procedures on policies and specifications for the gas system design are obtained or determined with appropriate persons
  • 1.4 Testing parameters are determined from organisational workplace procedures on policies and gas system specifications and discussed with appropriate person/s to ascertain the gas system project brief
  • 1.5 Equipment, tools and personal protective equipment (PPE) are selected and coordinated based on specified requirements and workplace procedures
  • 1.6 Work roles and tasks are allocated in accordance with design requirements and person/s competency
  • 1.7 Work is prioritised and sequenced for the most effective outcome, completed within an acceptable timeframe to an industry quality standard and in accordance with workplace procedures
  • 1.8 Liaison and communication with authorised persons, authorities, clients and land owners are undertaken to resolve gas system issues and coordinate design work activities
  • 1.9 Risk control measures are identified, prioritised and evaluated against the work schedule
  • 1.10 Relevant work permits are secured to coordinate the performance of work in accordance with requirements and workplace procedures
2 Assess impact of gas system on the environment
  • 2.1 Gas system logistics are determined and environmental impact on interconnected systems is assessed
  • 2.2 WHS/OHS and sustainable energy principles, functionality and practices to reduce the incidents of accidents and minimise waste are incorporated into the gas system project in accordance with workplace requirements and procedures
  • 2.3 Practicable design decisions are made on basis of safety and effective outcomes in accordance with workplace requirements and procedures
  • 2.4 Mathematical modelling is used to analyse the effectiveness of the design specification in accordance with workplace requirements and procedures
  • 2.5 Technical advice is obtained related to hazards, assessed risks and reasonably practicable risk control measures so that monitoring can be undertaken and appropriate authorities consulted, as required, in accordance with workplace requirements and procedures
  • 2.6 Specific data is analysed and compared with compliance specifications to ensure completion of the project within an agreed timeframe in accordance with requirements
  • 2.7 Environmental testing is undertaken in accordance with workplace requirements and procedures
  • 2.8 Work teams are arranged to ensure design planned goals are met in accordance with workplace procedures
  • 2.9 Solutions to unplanned events are responded to in accordance with workplace procedures, in a manner that minimises risk to personnel and equipment
  • 2.10 Quality of work is monitored against performance agreement and workplace organisational and industry standards
  • 2.11 Environmental strategic plans are developed incorporating organisational initiatives in accordance with workplace procedures
3 Identify and evaluate gas system options and prepare specifications
  • 3.1 Review of gas system are undertaken to ensure design complies with requirements and includes specifications and documentation needed to complete the gas project
  • 3.2 Design and construction resources option/s are identified, availability and price is determined, and maintenance requirements are documented
  • 3.3 Cost-benefit analysis is prepared and evaluation criteria are determined, any shortfalls in recommended option/s are justified and compliance requirements are met
  • 3.4 Appropriate persons are notified of design completion and gas system reports and completion documents are finalised
  • 3.5 Reports and completion documents are submitted to relevant persons for approval and as required, statutory or regulatory approval
  • 3.6 Approved copies of documents are issued and records are updated in accordance with workplace procedures
