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
Routine problems	Routine problems must be resolved by applying known solutions. Routine problems are predictable and include one or more of the following: iced lines high levels in pots/vessels smoke from flare flame out lack of header purge flow flash back inconsistent header composition blockage cold feed to warm header 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.
Abnormal conditions	Abnormal conditions include one or more of the following: weather loss of pilot fuel loss of utilities flame out high flare system back pressure cross connection between dissimilar systems
Responding to abnormal conditions	Responding to abnormal conditions includes the following: determining problems needing action accessing and applying relevant technical and plant data applying appropriate problem solving techniques to determine possible fault causes rectifying problem using appropriate solution within area of responsibility following through items initiated until final resolution has occurred reporting problems outside area of responsibility/ability to resolve to designated person
Flare system	The flare system includes one or more of the following: elevated flare ground flare vents (sometimes called ‘cold flare’) The flare system includes all items from the safety relief device through to the flare inclusive.
Hazards	Hazards include one or more of the following: access and exclusion zone heat blow backs leaks/loss of containment (LOC) ineffective isolations inadequate ventilation air ingress liquid carryover high liquid levels in knock out pots/separation vessels contraction and expansion (cold vapours) dislodgement of burning coke noise cryogenic temperatures radiation liquid hammer
Visual inspection	As relevant to the type of flare, visual inspection includes one or more of the following: pilot flame condition burn pattern ice on header lines vessel levels damage or deterioration smoke density
Logs and reports	Logs and reports include one or more of the following: paper or electronic based verbal/radio reports reporting items found which require action
