PURPOSE OF THE UNIT STANDARD 
This unit standard is for anyone who has to practice self-management principles responsibly and effectively during the installation and re-installing of castable/mouldable refractory materials by applying scientific techniques and solving related problems during refractory installation or maintenance processes.

A person credited with this unit standard is able to:
  • collect information and organise activities for castable/mouldable refractory materials installation and repair,
  • install castable/mouldable refractory materials,
  • remove and re-instate damaged castable/mouldable refractory materials,
  • perform end of work activities.

    This unit will contribute to the full development of the learner within the refractory construction environment by providing recognition, further mobility and transportability within the field of construction. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and progression within the construction and civil engineering contexts. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills, knowledge and understanding on:
  • Literacy and numeracy NQF 2,
