    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others as members of a team, group, organisation or community.

    Note:
  • The learner demonstrates the understanding that in an underground mining environment effective teamwork is of utmost importance in transporting people, equipment and materials by means of hoisting infrastructure. 

  • UNIT STANDARD CCFO ORGANISING 
    Organise and manage themselves and their activities responsibly and effectively.

    Note:
  • The learner demonstrates understanding that activities, tools and equipment have to be managed effectively in the shaft and hoist environment is as important to contribute to the efficiency of those systems as to be supported by them. 

  • UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively, using visual, mathematical and/or language skills in the modes of oral and/or written presentations.

    Note:
  • The learner demonstrates the ability to communicate effectively with co-workers in the shaft and hoist environment, in order to ensure safe and effective hoisting operations. 

  • UNIT STANDARD CCFO SCIENCE 
    Use science and technology effectively and critically showing responsibility towards the environment and health of others.

    Note:
  • The learner demonstrates an understanding of and ability to use advanced mining equipment and technology in terms of operating the hoist, related equipment and communications systems. 

  • UNIT STANDARD CCFO DEMONSTRATING 
    Demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation.

    Note:
  • The learner demonstrates understanding that various systems contribute to the overall safety and productivity of an underground working environment, and that it is as important to contribute to the efficiency of those systems as to be supported by them.

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

    UNIT STANDARD NOTES 
    Terminology:

    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 and Safety Act, 1996 (Act No. 29/1996), and Minerals Act and Regulations, 1991 (Act No. 50/1991).
  • Mandatory Codes of Practice.
  • SABS and other relevant standards.
  • Chief Inspector of Mines' Directives.

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

    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, then 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 candidate 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 candidate is able to 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, namely appropriateness, fairness, manageability, integration into work or learning, validity, direct, authentic, sufficient, systematic, open and consistent.

    Motivation with respect to number of Specific Outcomes:

    Even though there are less than four specific outcomes in this unit standard it represents a whole competency. It is NOT merely a description of tasks, jobs or procedures but it focuses on outcomes of activity. It also has a broad application across a range of contexts as stipulated in the unit standard.

    In addition this unit standard is considered as a milestone of learning in the sector. It is worth recognizing in its own right, as it is attributable to and achievable by an individual.

    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.
