This unit involves the skills and knowledge required to install gas flow, measuring and pressure regulating devices in accordance with relevant legislation, codes of practice, regulations and workplace procedures.

It includes installing of gas valves, pressure controllers, regulators and meters in gas facilities and stations.

This unit applies to the following types of gas stations, subject to all work health and safety (WHS)/occupational health and safety (OHS) and duty of care requirements being met for the workplace:

pressure reduction stations, district and customer regulator sets

compressor stations

meter stations and customer meter sets

custody transfer stations

inlets and city gates

scraper stations

gas storage facilities

main line valves.

The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 V a.c. or 120 V d.c.

Competency development activities in this unit are subject to regulations directly related to licencing.

Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to WHS/ OHS regulations.
