Elements and Performance Criteria

1. Co-ordinate planned shutdown
   • Use maintenance schedules to plan and co-ordinate shutdown of power generation system.
   • Follow procedures to shut down process supplies.
   • Follow organisational safety and standard operating procedures to initiate appropriate isolations and shut down systems.
   • Inspect system and record and report further maintenance requirements.
2. Respond to unplanned shutdown
   • Respond to unplanned shutdown immediately.
   • Initiate appropriate isolations, identify and locate cause of unplanned shutdown.
   • Rectify, isolate and or contain faulty plant where possible to allow continued production.
   • Follow procedures to shut down process supplies where fault cannot be rectified.
   • Assess effects of unplanned shutdown to determine impact on operations.
   • Communicate unplanned shutdown to appropriate personnel and power authorities, as required.
3. Record and report shutdown data
   • Record shutdown and corrective action processes.
   • Report shutdown information to relevant personnel and power authorities as required.

Performance Evidence

A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit, and must be able to provide evidence that they can:

co-ordinate planned shutdown of a power generation system within a pulp or paper manufacturing facility, at least twice in line with required enterprise intervals, and complete the following tasks after shut down:

inspect the system for these maintenance requirements

complete routine maintenance when shutting down the power generation system

complete basic records for shutdown processes and maintenance requirements

follow safe working practices when shutting down up the power generation system

use electronic and other control systems to control equipment during operations

communicate effectively, through written and verbal means, with others, in the work area when co-ordinating the planned shutdown of a power generation system

respond to one unplanned or emergency shutdown, which can be a real time event or by scenario, implement responses appropriate to the cause and complete a basic report on corrective action processes.
