Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Regulatory framework	The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following: legislative requirements, including work health and safety (WHS) industry codes of practice and guidelines environmental regulations and guidelines Australian and other standards licence and certification requirements All operations to which this unit applies are subject to stringent health, safety and environment (HSE) requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the HSE requirements take precedence.
Procedures	All operations must be performed in accordance with relevant procedures. Procedures are written, verbal, visual, computer-based or in some other form, and include one or more of the following: emergency procedures work instructions standard operating procedures (SOPs) safe work method statements (SWMS) formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant
Hazards	Hazards include one or more of the following: electricity gas gases and liquids under pressure structural hazards structural collapse equipment failures industrial (machinery, equipment and product) equipment or product mass noise, rotational equipment or vibration plant services (steam, condensate and cooling water) working at heights, in restricted or confined spaces, or in environments subjected to heat, dusts or vapours flammability and explosivity hazardous products and materials unauthorised personnel sharp edges, protrusions or obstructions slippery surfaces, spills or leaks extreme weather other hazards that might arise
Routine problems	Routine problems must be resolved by applying known solutions. Routine problems are predictable and include one or more of the following: leakage solids (formation fines) vibration loss of control of pressure and/or flow hydrate formation and blockages liquid slugging corrosion erosion sulphate reducing bacteria scale formation equipment failure Known solutions are drawn from one or more of the following: procedures training remembered experience Non-routine problems must be reported according to according to relevant procedures.
Site	Site includes one or more of the following: a well a nominated area in the gathering system another location where the operator is required to work
Site equipment	Site equipment includes one or more of the following: wellheads choke and control valves meters flow lines high point vents low point drains valves, including non-return and pressure/vacuum relief pumps, pump speed and their prime movers product separation units instrumentation and control systems (variable speed drive (VSD) and proportional integral derivative (PID)) testing equipment power units drive heads flares chemical injection equipment storage tanks/vessels autodumps leaks
Levels	Levels include, as appropriate to the site, one or more of the following: chemical storage levels lubricating oil levels water and gas levels battery levels drain levels
Lease maintenance areas requiring checking	Lease maintenance areas requiring checking include one or more of the following: land erosion fence and gate integrity weeds and other growth actions of feral or other fauna other required items
Identified faults	Identified faults include one or more of the following: instrumentation failure/malfunction electrical failure/malfunction mechanical failure/malfunction control system failure/malfunction mismatch between flow rates and system requirements wear, tear and corrosion of plant and equipment
