List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |

| 2.5 | Monitor work and plant, as required |
|
3 | Prepare plant for return to service | 3.1 | Confirm work is complete and site/plant has been left in acceptable condition |
| 3.2 | Accept handover from work party |
| 3.3 | Obtain authority to de-isolate |
| 3.4 | Execute authorised de-isolation plan |
| 3.5 | Sign off the de-isolation, as required |
| 3.6 | Reverse purge as required by plan for return to service |
| 3.7 | Execute authorised plan for return to service |

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include the ability to:
implement prepared isolation/de-isolation plan
read and interpret technical documentation and drawings/graphics
interpret safety data sheets (SDS)
undertake tests and interpret test results
complete required paperwork
apply procedures to control releases and remove energy and materials.
Evidence must be provided that demonstrates knowledge of:
isolation philosophy of organisation
isolation and preparation plan for work
plant energy sources and their methods of being de-energised and isolated
hierarchy of isolations
methods of proving isolations
methods and equipment used for purging and ventilation
decontamination methods and requirements for various materials and situations
as low as reasonably practicable (ALARP) concept
importance of appropriate rates of change for pressure and temperature for vessels and other plant
significance of time allowed for draining, purging and ventilation
fluid dynamics relating specifically to draining piping systems, including:
the ability of a liquid to ‘hang-up’ in pipework, the importance of identifying high point vents to release gas/vapours and low point drains to release liquids
determining the amount of liquid drained from a piping section to ascertain that draining has been effective/prove drainage
the potential effects (e.g. damage to tanks or vessels) of vacuum by not draining correctly (e.g. by pulling a vacuum behind a slug of liquid)
organisation procedures, including those covering:
safety, emergency and hazard control
work permit systems
communications
environmental management
standard operating procedures (SOPs).
The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence.
The collection of performance evidence is best done from a report and/or folio of evidence drawn from:
a single project which provides sufficient evidence of the requirements of all the elements and performance criteria
multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria.
A third-party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team.
Assessment should use a real project in an operational workplace. Where this is not possible or practical, assessment must occur using a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept).
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
In addition, the assessor or anyone acting in subject matter expert role in assessment must demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they must assess with a subject matter expert who does meet these requirements.
Technical competence can be demonstrated through one or more of:
relevant VET or other qualification/Statement of Attainment
appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
Currency can be demonstrated through one or more of:
being currently employed undertaking the type of work being assessed
being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
conducting on-the-job training/assessments of the type of work being assessed
being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work
