  • at least one natural gas installation
  • at least one liquefied petroleum gas (LPG) installation
  • a two-stage system
  • an over-pressure protection device
  • a minimum of two piping materials
  • certified Type A gas appliances.

Knowledge Evidence

To be competent in this unit, a candidate must demonstrate knowledge of:

  • drawing instruments and sketching techniques, including the use of conventional symbols
  • use of computers for documentation
  • computer-aided design (CAD) software
  • impact of ventilation on design
  • types, characteristics, uses and limitations of gas pipe work and consumer piping materials, including joining techniques and systems
  • how to access relevant information, including codes and standards
  • tools, materials and equipment used to design and size consumer gas installations
  • work health and safety (WHS) requirements for designing and sizing consumer gas installations
  • properties of gas, gas safety, combustion principles, pressure and megajoule rates.

Assessment Conditions

Assessors must satisfy the requirements for assessors listed in the Standards for Registered Training Organisations.

This unit must be assessed in the workplace or a close simulation using realistic workplace conditions, materials, activities, responsibilities, procedures, safety requirements and environmental considerations.
