Application
This unit of competency applies to operators who are responsible for operating and maintaining primary annealing equipment within the manufactured mineral products industry. This unit does NOT include secondary processes involved in reheating of glass for laminating or toughening processes, which are covered by PMC552041C Operate process ovens. This competency includes the operation of all ancillary equipment. This competency is typically performed by operators working either independently or as part of a work team. At all times they would be liaising with other members of the team. |

Required Skills
|
Required skills |
Required skills include: recognising process conditions which will lead to out of specification production implementing the enterprise's standard procedures and work instructions and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of the process and equipment reading and numeracy to interpret workplace documents and technical information |
Required knowledge |
Required knowledge includes: composition and nature of the glass startup and shutdown processes setup and annealing/conditioning process temperature and temporary and permanent stress pre-annealing, annealing and post-annealing processes construction and limitations of the reheating equipment out of specification situations quality problems such as: poor optics distortion excessive breakage non-uniform break pattern incorrect cross bend excessive bow scratches poor glass shape distinguish between causes of faults such as: raw materials/ribbon faults equipment types of defects/faults electrical/instrumental |
Evidence Required
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | It is essential that the reheating equipment be understood and that the importance of critical material properties, settings and readings is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that: temperatures and stress parameters are maintained within limits equipment set up is completed in accordance with work instructions startup and shutdown occur first time signals and alarms are responded to immediately process measurements are continually made, observed and interpreted quality is maintained to customer specifications. Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency. |
Context of and specific resources for assessment | Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. Assessment will occur over a range of situations which will include disruptions to normal, smooth operation. Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions. |
Method of assessment | In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units. Individual enterprises may choose to add prerequisites or co-requisite units relevant to their processes. |
Guidance information for assessment | Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Procedures | All operations are performed in accordance with standard procedures and work instructions |
Finishing equipment | This unit includes finishing equipment applicable to each of the specific areas of glass products manufacture, including: flat glass packaging, bottles and jars |
Equipment | Equipment may include: lehr and associated equipment gas burners instrumentation computers measuring and recording equipment communication equipment hand tools safety clothing and equipment |
Typical problems | Typical problems may include: process problems equipment problems quality problems temperature and strain problems equipment problems quality problems loss of utilities |
Occupational health and safety (OHS) | All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence |
