Elements and Performance Criteria

1. Contribute to decommissioning planning
   • Apply process understanding to the planning process
   • Identify the role and purpose of the plant and equipment
   • Ensure the work is coordinated effectively with others involved on the work site
   • Identify process conditions and apply to hazard studies
   • Undertake investigations following on from hazard studies
   • Obtain materials necessary to complete the work and check against job requirements
   • Obtain tools and equipment necessary to carry out the work and check for correct operation and safety
   • Prepare plans to ensure that procedures are performed in the correct sequence
   • Obtain approvals where necessary from appropriate authorities to ensure decommissioning process proceeds in accordance with the plan
   • Complete all appropriate documentation
2. Isolate and decontaminate equipment/unit according to procedures
   • Interpret and apply decommissioning plan
   • Identify and use appropriate safety equipment and materials
   • Isolate and decontaminate equipment components
   • Dispose of contaminated materials or components
   • Complete required documentation
3. Inspect, test and notify completion of work
   • Select tools and equipment appropriate to the testing/inspection requirements and utilise in accordance with manufacturer specifications and legislative requirements
   • Test/inspect in accordance with requirements
   • Ensure compliance with work health and safety (WHS) legislative requirements for risk assessment prior to disposal
   • Ensure any required additional work is undertaken/initiated
   • Notify work completion

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.
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) limited head spaces or overhangs working at heights, in restricted or confined spaces, or in environments subjected to heat, noise, 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
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 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
Documentation	Documentation includes one or more of the following: operating procedures WHS and environmental legislative requirements manufacturer specifications appropriate authority approvals (e.g. local councils, road authority, sewerage, stormwater, electricity, water and telephone) quality assurance inspection and test reports
Plant/pipeline systems	This unit of competency includes all items of equipment and unit operations which form part of the pipeline system including, as relevant to a particular plant/pipeline: pipes valves operating units electrical and electronic components programmable logic controllers (PLCs)/distributed control systems DCS) or other plant controls cathodic protection (CP) pressure/flow/temperature, regulation and meters
Tools, materials and equipment	Tools, materials and equipment include one or more of the following: hand tools power operated tools plant emergency equipment electrical and electronic test equipment gas detectors air compressor water pump
