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

PURPOSE OF THE UNIT STANDARD 
Learners who demonstrate competence as described in the outcomes of this Unit Standard will understand the importance and practical application of drawings related to gas installations.

The qualifying learner is able to:
  • Explain the role of drawings and specifications.
  • Identify drawings and symbols used on a construction.
  • Read and interpret process diagrams (P&IDs).
  • Produce a dimensioned, free-hand construction site drawing of a proposed or existing gas system.
  • Apply information from drawings in construction activities.

    This unit standard will contribute to the full development of any learner within the gas installations environment, by providing recognition, further mobility and transportability within the field. The knowledge, skills and understanding demonstrated in this unit standard are essential for upliftment, social and economic transformation in the gas installation environment.
