In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

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

PURPOSE OF THE UNIT STANDARD 
This standard is aimed at people who work or intend to work within a large process operation in the chemical or similar industry, and seek recognition for skills essential for operating within a chemical system.

Those learners who acquire the outcomes of this standard will know about and be able to contribute to the maintenance of a system, pertaining to the chemical industry.

For the purpose of this standard the following is understood as a system:
  • Equipment operated in combination to achieve a desired result in a chemical or related process operation
  • Operating a system included the integrated operation of the equipment that makes up the system


    The qualifying learner is able to:
  • Explain the role of an operator in the maintenance function
  • Prepare the system for maintenance
  • Prepare the work area for maintenance
  • Accept system back after maintenance is completed 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • Learners accessing this unit standard will have demonstrated competence against the unit standards or the equivalent; - Establish equipment start up conditions, Start up equipment, Shut down equipment, Contribute to maintenance of equipment

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
