Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and demonstrate the ability to:
identify and control hazards
use schematics and data to monitor plant and optimise performance
isolate the causes of problems and distinguish between causes of problems/alarm/fault indications, including:
instrument failure/malfunction
electrical failure/malfunction
mechanical failure/malfunction
equipment design deficiencies
product parameters (temperature, flows, pressure and levels)
process control system malfunction
power/utility failures
communicate effectively with team, group, supervisors and other personnel
recognise early warning signs of equipment/processes needing attention or with potential problems
take appropriate action to ensure a timely return to full performance
select and apply planned and unplanned start-up shutdown procedures
identify and communicate information required by others
complete written records.
Evidence must be provided that demonstrates knowledge of:
organisation procedures
hazards that may arise in the job/work environment, and:
their possible causes
potential consequences
appropriate risk controls
the function and location of the process/production equipment
interactions between plant items/processes
product specifications and tolerances
systems’ operating parameters
impact of external factors (e.g. variations in weather and feed)
system integrity limits
process control philosophies and strategies
emergency shutdown procedures
specific plant process operations
process-specific science (physics, chemistry and biochemistry) to the level of being able to interpret the science and extract factors controlling the process and product and by-product production rate and quality (e.g. for chemistry interpret the equation for factors controlling rate and yield and also interfering reactions, such as salts and hydrates)
basic science of upstream and downstream processes
emergency shutdown procedures
process drawings, such as piping and instrumentation diagram (P&ID) and process flow diagram (PFD )
cause and effect
control system architecture
basis of control for the plant/s
types of instrumentation and control systems, including feed forward, feedback and open control
types of instrumentation and control system components and their role, including primary sensing devices, final control elements and transducers/transmitters
how control loops and their components, including PID control, set points, controlled variable, indicated variable operate to control the process, and their limitations
interaction between multiple control loops, including cascade control
impacts of changing controller settings and the limits within which changes can be made
effective communication techniques
uninterrupt power supplies (UPS) and its applications and use.
The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence.
The collection of performance evidence:
should occur over a range of situations which include typical disruptions to normal, smooth operation of an operating plant
will typically include a supervisor/third-party report or other evidence focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
may include the use of an appropriate process control system controlling an industrial plant requiring demonstration of operation, start-up and shutdown procedures and responding to problems
may use an appropriate process control system linked to a simulator which simulates an industrial plant requiring demonstration of operation, start-up and shutdown procedures and responding to problems
may use industry-based simulation for all or part of the unit particularly where safety, lack of opportunity or significant cost is an issue.
Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in 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.
Assessment in a simulated environment should use evidence collected from one or more of:
simulator
walk-throughs
pilot plant operation
demonstration of skills
industry-based case studies/scenarios
‘what ifs’.
Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) 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.
