Unit of competency

Modification History

Release 1. Supersedes and is equivalent to PMAOPS247A Operate powered separation equipment

Application

This unit of competency covers the skills and knowledge required to operate powered dual phase separation equipment as used in a chemical, oil/hydrocarbons or metalliferous minerals processing or other plant.

This unit of competency applies to operators who are required to start up and shut down the equipment, monitor and adjust process parameters, identify operational problems with separation processes and equipment, including the driver powering the separation equipment, and take appropriate action.

Powered separation equipment can be used for gaseous, liquid and solids separation duties and includes one or more of the following:

• centrifuges
• rotary dryers
• rotary vacuum filters
• flotation cells/columns
• thickeners/clarifiers.

This unit of competency applies to an individual who may work alone although under routine direction and supervision. They may work as part of a team or group and will work in liaison with other shift team members and the control room operator, as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to PMAOPS247A Operate powered separation equipment

Performance Evidence

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:

• start up and shut down powered separation equipment
• monitor and operate powered separation equipment to meet specifications
• recognise early warning signs of equipment/processes needing attention or with potential problems
• determine the most likely cause of routine problems
• take action to ensure a timely return to full performance
• isolate and de-isolate equipment
• identify hazards and apply hazard control procedures.

Knowledge Evidence

Evidence must be provided that demonstrates knowledge of:

• principles of operation of separation plant/equipment
• process parameters and limits, including temperature, pressure, flow and pH
• routine problems, faults and their symptoms and the corrective action to be taken
• relevant alarms and actions
• all items on a schematic of the separator system and functions of each
• physics and chemistry relevant to each unit and the processes used, including kinetic energy effects
• function and troubleshooting of major internal components and their problems, such as internals, supports, nozzles, grids, agitators or scrapers
• hierarchy of control
• hazards that may arise in the job/work environment, and:
• their possible causes
• potential consequences
• appropriate risk controls.

Assessment Conditions

• 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
• must include the use of an appropriate industrial item of separation equipment requiring demonstration of operation, start-up and shutdown procedures and responding to problems
• may use industry-based simulation for part only of the unit 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:

• 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.
