Description
Employability Skills
Learning Outcomes and Application This unit involves the skills and knowledge required to calibrate volumetric measuring devices and gas analysers used in the measurement of gas quality.It includes inspecting, validating, calibrating and recommissioning of custody transfer devices and gas quality measuring equipment in accordance with reference industry standards to meet contractual, organisational or statutory requirements.This unit applies to any safe work site where gas industry operations occur. It also applies, where applicable, to other workplaces in the electricity supply industry (transmission and distribution and generation), the electrotechnology industry and the water industry, subject to all 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.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
