Elements and Performance Criteria
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 guidelinesenvironmental regulations and guidelines Australian and other standardslicence 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. |
Hazards | Hazards include one or more of the following:extreme coldbrittle fractureelectricitygases and liquids under pressure structural hazardsstructural collapseequipment failuresindustrial (machinery, equipment and product)equipment or product massnoise, rotational equipment or vibrationplant services (steam, condensate and cooling water)working at heights, in restricted or confined spaces, or in environments subjected to heat, dusts or vapoursflammability and explosivityhazardous products and materialsunauthorised personnelsharp edges, protrusions or obstructionsslippery surfaces, spills or leaksextreme weatherother hazards that might arise |
Routine problems | Routine problems are predictable and have known solutions and include one or more of the following:operating temperatures not maintainedunstable/sub-optimal operation (e.g. icing, moisture and fouling)critical variables and outputs out of range |
Non-routine problems | Non-routine problems are unexpected problems, or variations of previous problems and must be resolved by applying operational knowledge to develop new solutions, either individually or in collaboration with relevant experts, to:determine problems needing actiondetermine possible fault causesdevelop solutions to problems which do not have a known solutionfollow through items initiated until final resolution has occurredreport problems outside area of responsibility to designated personOperational knowledge includes one or more of the following:procedurestrainingtechnical information, such as journals and engineering specificationsremembered experiencerelevant knowledge obtained from appropriate people |
Start up/shut down | Start up/shut down includes the following:start up and shut down to/from normal operating conditionsstart up and shut down to/from isolated, cold or emptystart up and shut down to/from other conditions/situations experienced on the plant |
Procedures | All operations must be performed in accordance with relevant procedures.Procedures are written, verbal, visual, computer-based or in some other form, include one or more of the following:emergency procedureswork instructionsstandard operating procedures (SOPs)safe work method statements (SWMS)formulas/recipesbatch sheetstemporary instructionsany similar instructions provided for the smooth running of the plant |
Operate | Operate is to monitor, adjust/make change to the production unit and/or its component items to meet specifications, by one or both of the following:manually in the plant using local controller in the plant |
Product | Product includes anything produced by a process step and so includes:intermediate products, such as the product from one process step, which then becomes the feed for another |
