4 development and career advancement within the broader constituencies of the Ventilation, Occupational Health and Safety (VH&S) community. This will contribute to providing a better and safer working place for all people in the Mining industry in the Republic of South Africa. It will assist those occupational health and safety professionals who play an increasingly complex and crucial role in ensuring that the health and safety of employees have a well-grounded and comprehensive understanding of the key issues that are essential to meet these high demands. It covers the key issues involved at ground level and is designed to cover general health and safety issues with the specifics being incorporated in the Elective category. 3. There is a critical need in the industry to recognise learner competence regarding essential operations associated with a healthy, safe and productive working environment. A typical learning pathway in this field would start with this qualification and proceed to the National Certificate: Mine Ventilation, NQF Level Curriculum Structure Knowledge Subjects Number Title NQF Level Credits KS-01 Emergency Preparedness for Mine Ventilation (001) KS-02 Mine and Mineral Legislation for Ventilation (001) KS-03 Mine Ventilation Engineering Practice (001) KS-04 Occupational Hygiene Practice (001) 3 13 Total Knowledge Credits: 40 Practical Skills Modules Number Title NQF Level Credits PM-01 Select, check, use and maintain ventilation and occupational hygiene measurement instruments PM-02 Compile mine occupational environmental condition reports PM-03 Inform workers and management regarding sub standard mine occupational environmental conditions.

5 Practical Skills Percentage: 22% Workplace Percentage: 48% 1.3. International Comparability Mining activities occur in many countries all over the world, although the South African mining industry is more diverse than that of most other countries The international comparability exercise was conducted by comparing the outcomes of the proposed South African Qualifications to those in Qualifications, skills programmes and training courses of a number of countries with established mining industries. The reason for comparing against those countries is: Australia: International best practice. New Zealand: International best practice. United Kingdom: International best practice. India: Strong emerging economy. Zambia: African country (SADC).Botswana: African country (SADC).Namibia: African country (SADC). The above has determined that the countries chosen to benchmark this Qualification against were selected based on proven best practice within similar mining conditions. The United Kingdom, United Kingdom, New Zealand and Australia are considered best practice because many aspects of their mining operations relate and compare to similar aspects of mining operations within the South African industry. However, mining practices and standards are influenced world-wide by the presence of large multinational companies such as Anglo American, Rio Tinto, BHP Billiton and others. Training programmes in occupational hygiene and ventilation do not exist in the SADC region. No SADC countries have specific occupational hygiene and ventilation training programmes in place. It was found that the majority of occupational hygiene and ventilation training was conducted by South African companies in the SADC region. Therefore it was difficult to find any comparisons. This Qualification could not be compared with equivalent qualifications from a range of other countries because they do not have the specialisations in ventilation / environmental control as we do in South Africa. Rather the courses and programmes are in occupational health and safety. The ventilation areas are contained in mining operations programmes. Differences in training in South Africa are created through the need to comply with South African legislative requirements and specialisation in ventilation. Training in the area of OHS in South Africa has shown to be in V04-May2013 Page 5

6 demand in several countries of the SADC region and further a field in sub- Saharan Africa. It can be concluded that the proposed qualifications compares favorably with Qualifications and course presented internationally, on the following basis: a. There is a progression of learning (learning pathway).b. Although systems in the various countries scanned have different level indicators, there is a clear correlation between lower, intermediate and higher levels on the one hand, and related competencies on the other Entry Requirements 1. Successful completion of the National Foundational Learning competence level one. 2.
