    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    Assessment of learner achievements takes place at providers accredited by a relevant ETQA (RSA, 1998b) for the provision of programs that result in the outcomes specified for this unit standard. Anyone assessing a learner against this unit standard must be registered as an assessor with a relevant ETQA. Any institution offering learning that will enable achievement of this unit standard must be accredited as a provider with a relevant ETQA. The relevant ETQA according to the moderation guidelines and the agreed ETQA procedures will oversee moderation of assessment and is responsible for moderation of learner achievements of learners who meet the requirements of this unit standard. 

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    Essential embedded knowledge will be assessed through assessment of the specific outcomes in terms of the stipulated assessment criteria. Learners are unlikely to achieve all the specific outcomes, to the standards described in the assessment criteria, without knowledge of the listed embedded knowledge. This means that for the most part, the possession or lack of the knowledge can be directly inferred from the quality of the learner's performance. Where direct assessment of knowledge is required, assessment criteria have been included in the body of the unit standard.

    Credited learners understand and can explain:
  • Legal and site-specific requirements
  • What explosion barriers are
  • The principle and different types of explosion barriers
  • The importance of installing explosion barriers
  • The examination and use of personal protective in this regard
  • The examination of the tools, equipment and materials and the importance of examining the above
  • Why permission, where applicable, is obtained to enter the workplace
  • The dangers of entering a workplace without obtaining permission
  • How the designated workplace is examined and hazards and risks, pertaining to health and safety, are dealt with
  • The importance of dealing with hazards and risks
  • How the location where explosion barriers are to be installed is identified
  • The installation of the explosion barriers
  • Why the immediate vicinity is continuously assessed and hazards and risks pertaining to health and safety are dealt with
  • Why tools and equipment are cleaned in accordance with specified requirements
  • Why the workplace is cleaned to comply with specified good-housekeeping requirements.
  • That defective tools and equipment are dealt with in a manner consistent with specified requirements.

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems and make decisions using critical and creative thinking. Note: The ability of the learner to identify problems in terms of installing explosion barriers and making recommendations in this regard indicates that he/she can solve problems. 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others as a member of a team/group/organisation/community.

    UNIT STANDARD CCFO ORGANISING 
    Organise and manage oneself and one's activities responsibly and effectively. Note: The identification of the correct instruments and procedure will indicate that the learner can organise and manage activities in his/her working environment. 

    UNIT STANDARD CCFO COLLECTING 
    Collect, organise and evaluate information. Note: The ability of the learner to collect information on explosion barriers will indicate proficiency in collecting, organising and evaluating information. 

    UNIT STANDARD CCFO COMMUNICATING

    UNIT STANDARD ASSESSOR CRITERIA 
    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 learner 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 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.
