Application
This unit describes the performance outcomes required to install liquefied petroleum gas (LPG), compressed natural gas (CNG) and liquefied natural gas (LNG) electrical control equipment. It involves identifying and confirming work requirements, preparing for the work, installing LPG, CNG or LNG electrical control equipment, testing the installed equipment, and completing work finalisation processes, including clean-up and documentation.
It applies to those working in the automotive service and repair industry. The gas fuel system electrical control equipment includes that of agricultural machinery, forklifts, heavy commercial vehicles, light vehicles or mobile plant machinery.
Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.

Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
install one piece of liquefied petroleum gas (LPG), compressed natural gas (CNG) or liquefied natural gas (LNG) electrical control equipment in a vehicle.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to installing LPG, CNG and LNG electrical control equipment, including procedures for:
working with extremely cold and flammable gas
avoiding ignition of flammable gas when working on electrical systems
environmental requirements, including procedures for preventing loss of gas to atmosphere
requirements of Australian standards relating to installing LPG, CNG and LNG electrical control equipment:
AS/NZS 2739 Natural gas (NG) fuel systems for vehicle engines
AS/NZS 1425 LP Gas fuel systems for vehicle engines
properties of LP, CN and LN gases
operating principles of LPG, CNG and LNG electrical control equipment
post-installation testing procedures for LPG, CNG and LNG electrical control equipment, including fuel trim and exhaust gas analysis.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the LPG, CNG and LNG electrical control equipment they have installed in vehicles, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
AS/NZS 2739 Natural gas (NG) fuel systems for vehicle engines
AS/NZS 1425 LP Gas fuel systems for vehicle engine
manufacturer specifications for vehicle LPG, CNG or LNG systems
one piece of LPG, CNG or LNG electrical control equipment requiring installation
testing equipment for LPG, CNG or LNG electrical control equipment
tools, equipment and materials for installing LPG, CNG or LNG electrical control equipment.
