This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Those learners who demonstrate competence as described in the outcomes of this unit standard will be able to operate a furnace to melt materials and produce molten glass or an equivalent process.

The qualifying learner is able to:
  • Operate components of the furnace and the ancillary equipment or machinery.
  • Maintain normal operating conditions in a furnace.
  • Address abnormal, emergency and banked (idle) conditions in a glass melting furnace. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Learners accessing this unit standard will have demonstrated competence regarding:
  • Health, safety, environmental and quality issues and technology relevant to processing (chemical) materials.
  • Operating an integrated batch mixing plant.
  • Operating equipment.
    Where learners do not have the relevant expertise, appropriate adjustments must be made to the learning programme. 

  • UNIT STANDARD RANGE 
    Establishment of normal conditions is typically required after an abnormal situation such as a sustained power failure or down stream shutdown has occurred. 

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Operate components of the furnace and the ancillary equipment or machinery. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Describe components of the furnace with reference their function, method of operation and operating instructions . 
    ASSESSMENT CRITERION RANGE 
    1. Components include equipment, machinery, and control system(s) that are indefinable as separate parts or units with in the furnace `system`. (Typical examples of components are burners, electrodes, feeder, dust extraction and process control system).
     

    ASSESSMENT CRITERION 2 
    2. Conduct pre start-up checks according to instructions. 

    ASSESSMENT CRITERION 3 
    3. Components are checked started and maintained in the specified sequence accordance with process operating requirements and instructions. 

    ASSESSMENT CRITERION 4 
    4. Take remedial action (including stopping and maintaining) when a component does not operate in accordance with requirements or in accordance with site specific instructions. 
    ASSESSMENT CRITERION RANGE 
    Remedial action includes shut down and use of standby unit, repair or call-out of designated person.
     

    SPECIFIC OUTCOME 2 
    Maintain normal operating conditions in a furnace. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Interpret operating/production instructions ensuring understanding of what must be produced and any specific operating criteria for the operating period/shift. 

    ASSESSMENT CRITERION 2 
    2. Process operation is monitored and recorded in accordance with instructions. 

    ASSESSMENT CRITERION 3 
    3. Identify trends and deviations from set values are and make appropriate adjustments to process variables to keep process operation in accordance with instructions. 

    ASSESSMENT CRITERION 4 
    4. Adhere to Safety, and environmental instructions and quality assurance practices in accordance with site specific requirements. 

    SPECIFIC OUTCOME 3 
    Address abnormal, emergency and banked (idle) conditions in a furnace. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Identify abnormal, hazardous or non routine conditions (banked/idling/soaking) take actions in accordance with instructions within time frames that are accepted best practice. 
    ASSESSMENT CRITERION RANGE 
    Abnormal conditions are situations where normal process operation cannot continue for reasons that cannot be corrected by normal adjustment of process variables, hazardous conditions are situations which place people, environment, and or equipment at risk.
     

    ASSESSMENT CRITERION 2 
    2. Abnormal or hazardous conditions are reported and normal operating conditions are re-establish in accordance with instructions and safety and environmental requirements are maintained when addressing abnormal or emergency conditions in accordance with instructions and or best practice. 
    ASSESSMENT CRITERION RANGE 
    Actions may be include addressing the problem personally, instructing subordinate to address problem or calling for expert help such as an artisan, manager or other technical expert. Best practice is the action or activity accepted by the relevant industry and experts as appropriate under given or equivalent circumstances.
     


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    The Educational Training Quality Assurance Body (ETQA), for the Chemical Industry in consultation with GEN/FETQA will accredit providers offering learning towards this standard and will register assessors. They will also appoint the internal and external moderators. 

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE

    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems in which responses display that responsible decisions using critical and creative thinking have been made regarding the quality of the molten glass produced, state of the equipment and machinery used, material mixed and safety. 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others as a member of a team and organisation as is required to ensure that the batching activities proceed effectively complying with instructions and the downstream process requirements. 

    UNIT STANDARD CCFO ORGANISING 
    Organise and manage oneself and one`s activities responsibly and effectively to conduct work efficiently and enjoyably. 

    UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information to ensure productivity in the plant and quality of molten glass prepared. 

    UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively using visual, mathematical and/or language skills in the modes of oral and/or written persuasion ensuring that records comply with instructions and best practice and that relevant people know status of the melting operation. 

    UNIT STANDARD CCFO SCIENCE 
    Use science and technology effectively and critically, showing responsibility towards the environment and health of others whilst ensuring that glass produced is in accordance with instructions/specifications thereby minimizing wastage of material and energy. 

    UNIT STANDARD CCFO DEMONSTRATING 
    Demonstrating and understanding of the world as a set or related systems by recognising that problem solving contexts do not exist in isolation in that efficient melting is critical in the production of glass products in an integrated production operation which is achieve through attention to detail and completing work correctly. 

    UNIT STANDARD CCFO CONTRIBUTING 
    Contribute to the full personal development of each learner and the social and economic development of society at large, it must be the intention underlying any programme of learning to make an individual aware of the importance of reflecting on and exploring a variety of strategies to learn more effectively; participating as responsible citizens in the life of local, national and global communities; being culturally and aesthetically sensitive across a range of social contexts by undertaking and accepting responsibility for work that has impact on co-workers and a large production operation which as significant impact on the national economy including export of glass products and provision of glass products used by local citizens.
