IBMQI Overview NOISE Adoption Team 11 November 2018

IBMQI Introduction Purpose Manage Noise at Source - “Critical Control” To provide the Mining Industry Leaders with a consolidated industry-wide strategy for an Industry-wide Buy and Maintain Quiet Initiative (IBMQI) as well as a practical path-forward to execute the strategy Manage Noise at Source - “Critical Control” Noise is an Engineering problem Noise source measurements, after-effect analysis etc. – Occupational Health domain Its cheaper to manage noise @ source What is it? A standing decision from mining companies to procure equipment and maintain existing equipment that comply with specific noise emission requirements NOISE Adoption Team 11 November 2018

Noise Measurement & Reporting NOISE Adoption Team 11 November 2018

Noise Measurement Methodology NOISE Adoption Team 11 November 2018

Reporting & Recording Results of Noise Measurements IBMQI Measurements and Standards Subcommittee on 04 May 2017 workshopped the reporting of “individual pieces of equipment”: Step 1: Group equipment type/model into populations based on Activity Area (e.g. S215 Rockdrills used in Stoping Activity Area as a population). Step 2: Conduct noise samples on 5% of the equipment population, as per Activity Area (e.g. 5 samples for an equipment population of 100 S215 Rockdrills per Activity Area). Step 3: Calculate the Logarithmic Average Noise level, for the equipment population, making use of the Noise Measurement results obtained in Step 2 above. NOISE Adoption Team 11 November 2018

Reporting & Recording Results of Noise Measurements Step 4: Report the Logarithmic Average Noise result from Step 3 above for the equipment population for Noise Milestone Tracking purposes and not according to individual measurement results This Logarithmic Average result of the noise measurements for the population of equipment measured will be used for the reporting of Noise Milestone tracking. Note: Should the Logarithmic Average Noise result for the equipment population be greater or equal to 107dB(A), then the entire S215 Rockdrill population used in the Stoping Activity Area is reported as equipment greater or equal to 107dB(A) This individual piece of equipment within the equipment population should be investigated and not reported as an individual piece of equipment exceeding 107dB(A). Step 5: Investigate any individual noise measurement recorded for the sampled equipment population which was equal to or above the Milestone sound pressure limit of 107dB(A).

Noise Reduction of equipment NOISE Adoption Team 11 November 2018

Noise Reduction Process Screening process should now highlight ‘Critical Equipment’ Measure Noise Identify High Noise Emission Machinery Apply Screening Process measure identify prioritize action review List Critical Machines Certification of new design Identify Development Areas per Machine Test New Developments Staircase of OEM Development (MEMSA & Modernisation) Set Industry Target for Improvement Discussions can now be had between Engineer / Health Practitioner / Commodity Expert and the OEM Identifying an improvement programme for respective equipment Target setting and a staircase to develop and/or improve product Testing and Certification of new developments NOISE Adoption Team 11 November 2018

Screening of Critical Noise Equipment Progress OEM Interaction Mining Equipment Manufacturers of South Africa (MEMSA): Introduce the IBMQI to the office bearers. Align the MEMSA members with the IBMQI Process. Screening of Critical Noise Equipment Analysis of Equipment Noise Screening results: 8 Mining Companies submitted Screening results Screening Parameters: Noise Level Number of persons exposed Number of machines at work environment Duration of exposure Confined space Machine vibration Wear parameters Previous improvement ideas Effective hearing protection 90 Equipment Categories Screened Top 10 Critical Noise Equipment identified per Commodity NOISE Adoption Team 11 November 2018

Equipment Screening Tool 2015 Noise repository used Screening Tool Evaluation Challenges Limitations of the Screening process: Limited Access to Mining Companies Noise Repositories Correct understanding and use of the screening tool No Standardised Naming of Equipment Multi-disciplinary input required NOISE Adoption Team 11 November 2018

Conclusion NOISE Adoption Team 11 November 2018

Conclusions We can measure NOISE consistently across the mining industry – Understanding the Risk Value of the Screening Tool: Lead us to an industry (commodity) specific requirement (Best Achievable Requirement) Risk based approach Identification and information on our problematic equipment Avoid ‘Blanket’ approach on noise management initiatives - Prioritization Unlock “cheap” Innovation Assist in maintenance plans – prioritization of critical Noise equipment NOISE Adoption Team 11 November 2018
