| | 2.5 | Process variations/irregularities to procedures are recoded as necessary |
3 | Control process variations and monitor operations | 3.1 | Historical data on plant operations are used to assist the identification of problems and all available information processed to identify potential faults |
| | 3.2 | Required set point/output changes are undertaken to meet plant area and process requirements |
| | 3.3 | Production is adjusted in response to test results and control panel information |
| | 3.4 | Key process and environmental variables are monitored and appropriate action taken |
| | 3.5 | Controller settings are adjusted in accordance with procedures with advanced control features utilised as appropriate |
| | 3.6 | Plant area is optimised in accordance with guidelines |
| | 3.7 | Calibration operations are made as appropriate |
| | 3.8 | Coordination with stakeholders external to the plant area is undertaken as required |
| | 3.9 | Adjustments and variations to specifications/schedules are recorded and communicated to appropriate personnel |
4 | Facilitate planned and unplanned process start-ups and shutdowns | 4.1 | Procedures to planned startup and shutdown processes are selected and applied |
| 4.2 | Procedures to unplanned shutdown processes are selected and applied where required |
| | 4.3 | Required emergency responses are implemented |
| | 4.4 | Necessary information is communicated to all personnel affected by events |
| | 4.5 | Required information is logged regularly |
5 | Respond to alarms or out of specification conditions and control hazards | 5.1 | System(s) affected by the alarm or condition are identified, prioritised and appropriate action taken |
| 5.2 | Alarm or incidents are responded to promptly by following procedures |
| | 5.3 | Any out of specification material is dealt with in accordance with procedures and the problem/solution communicated to appropriate personnel |
| | 5.4 | Incident information is recorded as required and details of the alarm and action taken communicated to the next shift at change over |
| | 5.5 | Incidents are followed up to confirm that appropriate action has been taken |
| | 5.6 | Hazards in the production/processing work area are identified and the risks arising from those hazards assessed |
| | 5.7 | Measures to control risks are implemented in line with procedures and duty of care |
6 | Resolve other problems within scope of responsibility | 6.1 | Possible problems in equipment, control systems or process are identified to determine problems needing action |
| 6.2 | Possible fault causes are established and problems rectified using appropriate solution within area of responsibility |
| | 6.3 | Initiated control actions are followed through until final resolution has occurred with problems outside area of responsibility reported to designated person |
Consistently:
recognise early warning signs of equipment/processes needing attention or with potential problems
determine and analyse the range of possible plant problem causes and the most likely cause
take appropriate action to ensure a timely return to full performance
recognise obvious problems in related plant areas and make an appropriate contribution to their solution
Distinguish between causes of problems/alarms/fault indications, such as:
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
software problems
Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems
Avoid backtracking, work flow interruptions or wastage
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
Interactions between control loops
Interactions between plant units within the entire plant
The architecture and location of the glass process/production equipment
Specific glass plant process operations
Interactions between glass plant items/processes
Glass product specifications and tolerances
Systems operating parameters
System integrity limits
Process control philosophies and strategies
Emergency shutdown procedures
Basic science of upstream and downstream glass processes
Impact of external factors (e.g. variations in weather and feed)
Complex process drawings (e.g. piping and instrumentation diagrams (P&ID), probability of failure on demand (PFD) and cause and effect)
Basis of control for glass processing plant/s
Instrumentation and control systems, including feed forward, feedback and open control
Instrumentation and control system components (e.g. relevant primary sensing devices, final control elements, and transducers/transmitters)
Control loops, including P&ID control, set points, controlled variable and indicated variable
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
Organisational procedures
Assessors must:
hold training and assessment competencies as determined by the National Skills Standards Council (NSSC) or its successors
have vocational competency in the furnishing industry at least to the level being assessed with broad industry knowledge and experience, usually combined with a relevant industry qualification
be familiar with the current skills and knowledge used and have relevant, current experience in the furnishing industry.
Assessment methods must confirm consistency of performance over time rather than a single assessment event and in a range of workplace relevant contexts.
Assessment must be by observation of relevant tasks with questioning on underpinning knowledge and, where applicable, multimedia evidence, supervisor’s reports, projects and work samples.
Assessment is to be conducted on single units of competency or in conjunction with other related units of competency. Foundation skills are integral to competent performance in the unit and should not be assessed separately.
Assessment must occur on the job or in a workplace simulated facility with relevant process, equipment, materials, work instructions and deadlines.
Access is required to control systems for glass processing plant and equipment, workplace documentation, procedures and job requirements.
