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.
   • Interpret and apply decommissioning plan
   • Identify and use appropriate safety equipment and materials
   • Isolate and decontaminate equipment components as required
   • Dispose of contaminated materials or components as required
   • 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 OHS legislative requirements for risk assessment prior to disposal
   • Ensure any required additional work is undertaken/initiated
   • Notify work completion.

Required Skills

This describes the essential skills and knowledge and their level required for this unit

Required skills

Demonstrated knowledge and ability to plan the decommissioning process arrange resources as required coordinate own work and the work of others including onsite contractorsoperators interpret and solve operational problems as they arise and take appropriate action document the decommissioning and recommendations for safe storagemaintenancedisposal

Required knowledge

Competence to include the ability to apply and explain chemistry of materials involved principles of operation of the process principles of operation of the equipment involved all items on a schematic of the plant and the function of each correct methods of stopping plant items function of major components HAZOP study process and the interpretation of findings results and impact of a HAZAN study hazardous substances legislation the process of hazard identification risk assessment and control sources of hazard information such as Material Safety Data Sheets safe disposal methods of materials and equipment decontamination processes

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for the Training Package
Overview of assessment	Assessment of this unit should include demonstrated competence on actual plantpipeline and equipment in a work environment The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency Simulation may be required to allow for assessment of parts of this unit It is possible that a simulation will be required to ensure that the technician is competent before taking a significant role in a decommissioning activity Decommissioning is an infrequent activity and so it may not be practical or equitable to wait for an actual decommissioning to occur to use this as the basis for assessment Simulation should be based on the actual plant and will include walk throughs of the relevant competency components Simulations may also include the use of case studies scenarios and role plays This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of whatif scenarios both on the plant during demonstration of normal operations and walkthroughs of abnormal operations and off the plant
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster Consistent performance should be demonstrated In particular look to see that potential problems are recognised the range of possible causes can be identified and analysed and the most likely cause determined appropriate timely action is taken obvious problems in related plant areas are recognised and an appropriate contribution made to their solution These aspects may be best assessed using a range of scenarioscase studieswhat ifs as the stimulus with a walk through forming part of the response These assessment activities should include a range of problems including new unusual and improbable situations which may have been generated from the past incident history of the plant incidents on similar plants around the world hazard analysis activities and similar sources
Context of and specific resources for assessment	Assessment will require access to a plant over an extended period of time or a suitable method of gathering evidence of operating ability over a range of situations A bank of scenarioscase studieswhatifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions
Method of assessment	In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units In a major hazard facility it may be appropriate to assess this unit concurrently with relevant OHS units
Guidance information for assessment	Assessment processes and techniques must be culturally appropriate and appropriate to the oracy language and literacy capacity of the assessee and the work being performed

Range Statement

The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Codes of practice/ standards	Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
Context	This competency unit includes the functions of : liaison with manufacturers, engineering personnel, designers, maintenance personnel participation in hazard and operability studies (HAZOP) and hazard analysis studies (HAZAN) removal of plant and equipment from service, which may include: 'mothballing' storage disassembly demolition decontamination of equipment disposal of equipment and waste. This competency unit includes the understanding and application of: OHS regulations especially those related to plant codes of practice disposal procedures and regulations. All operations are performed in accordance with standard operating procedures.
Health, safety and environment (HSE)	All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State 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	Procedures may be written, verbal, computer-based or in some other form. They include: all work instructions standard operating procedures formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant. For the purposes of this Training Package, 'procedures' also includes good operating practice as may be defined by industry codes of practice (eg Responsible Care) and government regulations.
