SIM 03-06-03 SIMRAC Silicosis Control Programme -- Phase 2 6th January 2005 Motivation SIMRAC is a partner in the WHO/ILO initiative for the global elimination of silicosis. Since its establishment in 1994, SIMRAC has funded projects in dust measurement and control, but silica exposure, with related silicosis and tuberculosis, remains a priority challenge for the mining industry. It is essential to evaluate the existing practice in relation to control requirements, set exposure reduction targets and established best practice to meet these targets for silica exposure. In addition, new technologies for preventing or allaying dust pollution should be reviewed and research conducted, if necessary. This project is to research the containment/elimination of silicosis in the South African mining industry as identified in regional and national workshops. Proposals for the tracks are NOT being sought at this stage. SIMRAC is seeking an overall Project leader and 3 project track leaders who will form a team to collaborate with the Mine Health and Safety Council in managing and shaping this important project. An invitation is extended to experienced research managers to apply for these 4 positions by submitting a detailed curriculum vitae with a covering letter explaining which position is being sought, with which research institution they are or will be affiliated, their relevant personal experience and an indication of the anticipated number of working days required and daily remuneration rate sought. In addition, researchers interested in specific components of any of the three tracks should submit a curriculum vitae and covering letter detailing the component/s in which they have a specific interest. These contributors will be contacted and considered by SIMRAC and the management team once the 4 individuals have been appointed. Part A: Dust Measurements and Reporting Previous SIMRAC research and the lack of progress in eliminating silicosis highlighted the problem of measurement, analysis and reporting of respirable dust exposures. SIMRAC has prioritised dust measurement and reporting as an area for research in the Silicosis Control Programme. Primary outputs Evaluate the techniques used in South African mines for determination of exposure to respirable crystalline silica. This includes the sampling instrumentation; sampling strategies, sample analysis, quality assurance/control and reporting which will be compared with best practice. Review and assess techniques used in South African laboratories for respirable silica analysis on filter samples and the implementation of an international quality control check with standard samples on the laboratory analysis performance. Develop standard samples for instrument calibration for quartz analysis. Develop a manual of best practice for the assessment of exposure to respirable crystalline silica. Will include but not be limited to appropriate air sampling equipment, air sampling equipment preparation, field survey procedures including filter handling, sampling strategies, gravimetric determination, analytical methodologies for crystalline silica, laboratory quality assurance and reporting. Develop a manual of best practice to assess the engineering and other control measures in place to minimise exposure to crystalline silica.

This needs to be re-established using current educational methods and technology, which have developed in the intervening years, to raise awareness about dust exposure and health effects. SIMRAC has targeted the area of human resources training/ technology transfer as one of the priority areas for the Silicosis control programme. Close collaboration is required with the dust measurement and dust control projects on silicosis elimination.
