Hazards may include, but not be limited to: chemical hazards; thermal hazards; manual handling hazards; guarding of machinery requirements; illumination of work area; rubbish and combustibles in area; leakage of steam; leakage of fuel; obstructions in the work area; fire; noise; vibration; water and working at heights.
Operational checks may include, but not be limited to: quality of steam supply; cooling water system; condenser operation; position and operation of valves and fittings; cylinder drainage system; lubrication system, speed control, vibration level, steam reticulation line pressure, and operation of control/safety devices.
Personal Protective Equipment (PPE) may include, but not be limited to: prescribed under legislation, regulation, codes of practice, and workplace policies and practices; hard hat; safety boots; gloves; high visibility clothing; breathing, hearing, sight, skin and sun protection; fall-arrest equipment such as harnesses and lanyards, horizontal lines and inertia reel.
Pre-operational safety checks may include, but not be limited to: steam supply system; position and operation of steam turbine valves; safety devices; overspeed shut-down; pressure relieve devices; speed governor; exhaust system; auxiliary equipment and lubrication system.
Procedures may include, but not be limited to: manufacturer’s guidelines (instructions, specifications or checklists); industry operating procedures and workplace procedures (work instructions, operating procedures, checklists).
Recorded may include, but not be limited to: operations and maintenance of steam turbine equipment; difficulties or issues; environmental issues; recommendations for future work; results; costs; hazards; incidents or injuries; dangerous occurrences or equipment malfunctions using log books; proformas; production reports and maintenance records.










A simulator is a device used especially in training to reproduce the conditions of the working situation, enabling tasks to be learned and practised safely and economically.
Shut down checks may include, but not be limited to: checks of cooling down process; steam supply isolated; load on steam turbine; auxiliary equipment shut-down; cylinder drain system and isolation from any common connection.
Start-up checks may include, but not be limited to: position and operation of valves and fittings; operation of lubrication system; operation of drainage system; steam quality; heat input; operation of auxiliary equipment; freedom of rotation of steam turbine; steam turbine warm up; operation of steam traps and steam line purge systems; warm up of reticulation system and reticulation line pressure.
All industrial equipment where steam acts on a steam turbine or rotor to cause a rotary motion with any or all of the following features: attached condensers; multi-wheeled; multi-staged heat exchange extraction process, and speed greater than 3600 rpm may include axial flow, back pressure, condensing, impulse, non-condensing, pass out, radial flow, reaction and velocity compounding steam turbines with a power output of greater than 500kW. The operation may be assisted by remote indicators of plant status and other parameters monitored (e.g. central control stations), in wet, noisy, dusty or hot areas or during continuous operation.
Steam turbine emergencies and contingencies may include, but not be limited to: identification of type of emergency; isolation of steam supply; selection and application of appropriate firefighting equipment; notification of upstream steam supplier and operation of steam turbine only when safe to do so.
Testing may include, but not be limited to: loss of a major auxiliary controls response checks; stand-by plant tests; valves operating checks; emergency governor operation test; performance tests and alarm and protection tests.

EVIDENCE GUIDE
9) 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
9.1)

Successful assessment of this unit meets the competency requirement of state and territory WHS Regulations, including licensing.
State/territory WHS regulators have mandated the use of Assessment Instruments and Instructions for Assessment for this unit which have been endorsed by the national body responsible for WHS matters.

Critical aspects of evidence required to demonstrate competency in this unit
9.2)

Compliance with organisational and site policies and procedures including quality requirements and state or territory legislation applicable to workplace operations.
Compliance with WHS and environmental regulations, policies and procedures.
Effectively communicate and work safely with others in the work area.
Identify hazards associated with the operation of the steam turbine and put in place effective hazard controls for those hazards identified.
Effectively start-up, monitor and shutdown a steam turbine which meets the definition of this licence class.
Control and monitor any ancillary equipment which may be connected or interfaced to the steam turbine.
Compliance with Commonwealth, state or territory regulations for the acquisition of a regulatory authority licence.

Context of and specific resources for assessment
9.3)

Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instrument.
Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace.
Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is made available to suit the assessment and the workplace.
Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints.
Assessment is to comply with relevant appropriate standard requirements.
Applicants must have access to:
PPE for the purpose of the Performance Assessment.
Appropriate safety equipment in safe condition
Appropriate steam turbine and associated equipment in safe condition
Communication equipment, where applicable.

Method of assessment
9.4)

Assessment must be conducted using the endorsed Assessment Instruments. These Instruments provide advice on their application.
The use of simulators in the assessment of this unit of competency is acceptable.
Assessment may be in conjunction with the assessment of other units of competency.
Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstances, but is able to be transferred to other circumstances.

Concurrent assessment and relationship with other units
9.5)

Further information about endorsed Assessment Instruments may be obtained from state and territory WHS regulators.
