PURPOSE OF THE UNIT STANDARD 
This unit standard is for people who assist the leaching operator in the leaching process to obtain maximum extraction of tannin per autoclave of chopped bark, whilst adhering to other agreed standards pertaining to performance, safety, quality, and the environment.

People credited with this unit standard are able to:
  • Operate in close liaison with leaching operators
  • Assist in preparing autoclave and commence leaching process
  • Assist in discharging autoclave at end of leaching cycle
  • Ensures autoclave section is clean at all times 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    A Learner who wishes to enter a learning programme for this Unit Standard must be able to demonstrate:

    i) Competency in mathematical and communication skills equivalent to that of a person who has qualified in these subjects at NQF Level 2;
    ii) An understanding of the basic activities of the tannin extraction process and procedures of the relevant workplace;
    iii) Knowledge and skills in the relevant workplace procedures, health and safety measures equivalent to NQF level 2 requirements. 

    UNIT STANDARD RANGE 
    a) The scope of this Unit Standard covers

    i) The whole environment that can be described as the autoclave section.
    ii) All the personnel involved in all the activities relating to the leaching process.
    iii) All the material that is handled and processed in this work area by the leaching crew.
    iv) All the organisation's work procedures and safety regulations relating to this work area and the leaching crew.
    v) All the relevant OSHACT stipulations which have a bearing on the leaching process and all the other activities in this work area.

    b) The context of this Unit Standard relates to the training of a Learner at NQF Level 3 in the tannin extract leaching process.

    c) The Level assigned to this Unit Standard, i.e. Level 3, is appropriate because it entails the training of a novice in the tannin extract leaching operation and is a progression of the skills acquired from Levels 3 to 4.
