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

PURPOSE OF THE UNIT STANDARD 
To recognise the competence of learners who are able to operate a non-continuous furnace as used in some molten glass production operations.

The qualifying learner is able to:
  • Operate components of the furnace and ancillary equipment or machinery.
  • Commission and establish normal operating conditions from a cold furnace.
  • Maintain normal operating conditions and address abnormal or emergency conditions in a furnace.
  • Shut down a furnace.

    A non-continuous furnace comprises of furnace, heating system (electric and or gas), feed system (manual conveyors and vibratory), tapping system (that maybe continuous or batch and may require titling or lifting the furnace).
    Safety and dust handling facilities are considered to be part of the whole 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 energy supply failure or down stream shutdown has occurred.

    5. Interpret and understand operating/production instructions ensuring any specific operating criteria for the operating period/shift is adhered to. 

    ASSESSMENT CRITERION 6 
    6. Monitor and record what must be produced and process operation is in accordance with instructions 

    ASSESSMENT CRITERION 7 
    7. Identify trends, abnormal conditions, and deviations from normal values and make appropriate adjustments to the process variables to keep process operation in accordance with instructions. 

    ASSESSMENT CRITERION 8 
    8. Carry out feeding and tapping in accordance with instructions and adhere to all safety, and environmental and quality assurance practices in accordance with site specific requirements. 

    SPECIFIC OUTCOME 3 
    Address abnormal or emergency conditions in a furnace and shut down a furnace. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Identify and report abnormal, emergency, hazardous conditions and other non-routine conditions and take actions 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. Safety and environmental requirements are maintained conditions addressing abnormal or emergency conditions and conditions normal operating conditions are re-established. 
    ASSESSMENT CRITERION RANGE 
    Actions may 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.
     

    ASSESSMENT CRITERION 3 
    3. Pre-shutdown activities are conducted on the furnace and ancillary equipment according to instructions. 

    ASSESSMENT CRITERION 4 
    4. Communicate information concerning shut down to appropriate people conditions and check and carryout routine servicing/maintained conditions in accordance with instructions and best practice. 


    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.
