    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    Terminology:

    Specified requirements:
    Specified requirements include legal and site-specific requirements and are contained in one or more of the following documents:

    Legal:
  • Relevant Acts: e.g. Mine Health & Safety Act, 1996 (Act no 29/1996), and Minerals Act and Regulations, 1991 (Act no 50/1991).
  • Mandatory Codes of Practice.
  • SANS and other relevant Standards.
  • Chief Inspector of Mines' Directives.

    Site specific:
  • Hazard Identification and Risk Assessments (HIRA).
  • Occupational Health and Safety Risk Management Programme.
  • Voluntary Codes of Practice.
  • Managerial Instructions.
  • Mine Standard Procedures.
  • List of Recorded OH&S Risks.
  • Working Guides.
  • Equipment and Materials Specifications of 1993.

    Notes to Assessors:

    Assessors should keep the following principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Remember we want to declare the person competent in terms of the title. Where assessment at title level is unmanageable, focus assessment around each specific outcome, or groups of specific outcomes.
  • Make sure evidence is gathered across the entire range, wherever it applies. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the learner is able to perform in the real situation.
  • Do not focus the assessment activities on each assessment criterion. Rather make sure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • The assessment criteria provide the specifications against which assessment judgements should be made. In most cases, knowledge can be inferred from the quality of the performances, but in other cases, knowledge and understanding will have to be tested through questioning techniques. Where this is required, there will be assessment criteria to specify the standard required.
  • The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the learner can achieve the outcomes again and again and again. This means assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.
  • All assessments should be conducted in line with the following well documented principles of assessment: appropriateness, fairness, manageability, integration into work or learning, validity, direct, authentic, sufficient, systematic, open and consistent.

    Unit Standard Justification:

    Level:

    Attribute; Level; Justification:
  • Skills; Level 2; The skills required have some variety but are still fairly simple.
  • Procedures; Level 2; Although the procedure is known and familiar (as level 1) it is not as repetitive.
  • Context; Level 2; Routine and familiar.
  • Knowledge; Level 3; Relevant theoretical knowledge is required to be fully competent.
  • Information processing; Level 3; Interpretation as opposed to basic processing is required.
  • Problem Solving; Level 2; The learner will only have to apply given solution to known/familiar problems.
  • Orientation of activities; Level 3; Directed, with some autonomy.
  • Application of responsibility; Level 3; Learner's output is quality checked.
  • Orientation of scope of responsibility; Level 2; Some responsibility for quantity and quality, and possible responsibility for guiding others.

    Average Level: 22/9 = 2.44.
    Actual Level Assigned: 2.

    Credits:

    Total hours required by the learner to achieve the required outcome:

    Activity; Hours:
  • Classroom Teaching; 10 hours.
  • On-The-Job Training; 18 hours.
  • Mentoring required; 0 hours.
