Description
Notes
Elements and Performance Criteria
No information
Databases may be:
electronic databases (such as Access, DB, Oracle)
other electronic forms (such as spreadsheets)
card files
other paper based systems.
Hazard identification and analysis process may include
hazard and operability (HAZOP) studies
hazard analysis (HAZAN) studies
other company specified procedures.
Scheduling may include:
electronic project planning tools (such as MS Project)
other specialised planning software
paper techniques.
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.

Assessment context and methods
Assessment for this unit of competency will be on a plant. 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.
Typically this unit will be assessed by a shut down planning project. It may not be appropriate to wait until the shut down planning is completed, as it may be desirable to test for competence before taking a major role in a shut down. In this case a simulation should be used.
This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of what if scenarios both on the plant (during demonstration of normal operations and walk-throughs of abnormal operations) and off the plant.
Critical aspects
Competence must be demonstrated in the ability to undertake a structured analysis of the activities to be completed during the shut down and then undertaking the planning in a systematic manner.
Consistent performance should be demonstrated. In particular look to see that:
the plan minimises the time of the shut down
the plan identifies and addresses safety, health and environment issues
required activities/tasks are actively sought, broken into their components and scheduled
plant drawings (eg, P&IDs) and engineering specifications are interpreted correctly
priorities for action consider all relevant factors.
This will typically be assessed by a major shut down project on an operating plant. One complex project, or a number of simple projects, are required to demonstrate competence. As shut down planning is usually a team activity, it is appropriate to assess the technician while they undertake this activity as part of the team, provided competence in all aspects can be demonstrated.
Resource implications
Assessment will require access to an operating 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 scenarios/case studies/what ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.
Other assessment advice
In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.
It may be appropriate to co-assess this unit with:
BSBCMN402A Develop work priorities
BSBCMN411A Monitor a safe workplace
BSBFLM405A Implement operational plan
BSBFLM504A Facilitate work teams
BSBFLM505A Manage operational plan
PMACOM400A Develop plant documentation.
Essential knowledge
Competence includes an understanding of the operation of the plant and its units. It requires the ability to:
identify all necessary sequences of activities to ensure safe and efficient shut down
identify health and safety implications associated with plant shut downs and formulate risk controls by applying the hierarchy of control (it is not expected that the candidate will be able to conduct technical hazard analysis procedures but they should be able to interpret and use the outcomes of such analyses)
negotiate with a range of people to obtain the best outcome for the shut down from the conflicting priorities
use planning tools to develop and modify complex plans/schedules.
