Unit of competency
Modification History
Release 1. Supersedes and is equivalent to PMASMELT266B Deliver molten metal
Application
This unit of competency covers the skills and knowledge required to transport molten metal, such as used in the aluminium smelting process, using mobile transport equipment and crucibles.
This unit of competency applies to operators who are required to collect filled crucibles for transportation, move the crucible to required location, transfer/siphon molten metal to the destination furnace, and recognise and respond to 'out-of-parameter' issues.
This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members and the control room operator, as appropriate. The operator would be part of a team during start-up and shutdown procedures.
This unit of competency does not require the operation of a central control panel.
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 PMASMELT266B Deliver molten metal
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:
- collect filled crucibles for transportation and move to required location
- transfer/siphon molten aluminium to the destination furnace
- monitor equipment conditions and maintenance requirements and take action
- monitor process parameters and performance and make adjustments according to procedures
- recognise early warning signs of equipment/processes needing attention or with potential problems and take action to ensure a timely return to full performance
- isolate and de-isolate equipment
- identify hazards and apply hazard control procedures
- respond to emergencies
- apply housekeeping procedures, including cleaning the area, removal of contaminants, safety inspections and rectification of issues that could compromise safety.
Knowledge Evidence
Evidence must be provided that demonstrates knowledge of:
- all items on a schematic of the siphon equipment, delivery equipment and functions of each
- basic principles of operation of main equipment items, including siphoning equipment and crucible transport equipment
- basic understanding of the product specifications and variations required on the input and output side
- process parameters and limits (e.g. temperature)
- emergency responses, including those related to:
- leak/loss of containment
- evacuation due to fire or open cell circuit
- loss of power
- excessive emissions of fumes or particulate
- major oil spill
- equipment failure
- typical hazards associated with heat, electricity, hydraulics and pneumatics and high pressure piping and valves, pinch and crush points on conveyor systems, mobile equipment, hazardous materials, banned items, suspended loads and hydration and heat stress, and how to recognise them
- correct use of personal protective equipment (PPE), including specific insulated boots, heat resistant material, full-ventilated suits, full-face masks and other situation-specific equipment.
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 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
