This unit involves the skills and knowledge required to monitor and operate complex flow control, measuring and regulating device to monitor and control gas supply in gas distribution system in accordance with relevant legislation, codes of practice, regulations and workplace procedures.

It includes on site local inspecting and controlling of gas flow and pressure; local monitoring of gas flow, pressure and measurement; recording and reporting on anomalies to gas flow pressure and measurement; and controlling the system to organisational and statutory requirements.

This unit applies to gas distribution systems, subject to all work health and safety (WHS)/occupational health and safety (OHS) and duty of care requirements being met for the workplace.

The application of the skills and knowledge described in this unit may require a license or permit to practice in the workplace.

Other conditions may apply under state and territory legislative and regulatory licencing requirements which must be confirmed prior to commencing this unit.
