PURPOSE OF THE UNIT STANDARD 
This unit standard reflects the skills, values and knowledge required by people in the field of Small Scale Mining who are required to manufacture explosives on site for surface excavations.

People credited with this unit standard are able to:
  • Calculate the amounts of the ingredients needed to manufacture the required explosives.
  • Collect and mix the components into a uniformly blended explosives product.
  • Record and account for both the ingredients and the explosives produced.
  • Carry out basic maintenance and housekeeping on the mixing equipment. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in:
  • Communication and mathematical literacy at NQF Level 2.
  • Occupational Health and safety at NQF Level 2.
  • Information Technology at NQF Level 2.
  • Handle, store and transport explosives at NQF Level 2.
  • Basic understanding of operations in surface mines and quarries at NQF Level 2.

    ASSESSMENT CRITERION 3 
    The equipment and tools are cleaned to ensure there are no residual explosives and/or an environmental problem in accordance with operational requirements. 

    ASSESSMENT CRITERION 4 
    The equipment and tools are examined for sub-standard conditions and maintained to ensure there are no hazards in the manufacture of explosives, in accordance with operational requirements. 


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing a learner or moderating the assessment of a learner against the qualification must be registered as an assessor with the relevant Education, Training, Quality, Assurance (ETQA) Body, or with an ETQA that has a Memorandum of Understanding with the relevant ETQA.
  • Any institution offering learning that will enable the achievement of this qualification must be accredited as a provider with the relevant Education, Training, Quality, Assurance (ETQA) Body, or with an ETQA that has a Memorandum of Understanding with the relevant ETQA.

    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.
