Petra Diamonds Limited Sustainability Report 201220HEALTH AND SAFETYHealth and SafetyInstilling a safety culture continuedSafety continuedAlthough the majority of our recorded LTIs are of a low level of severity, we remain focused on improving our performance further. We take a range of steps to mitigate high risk issues, including: $ encouraging reporting of incidents and near misses;$ reviewing and updating policies, codes of practices and methods for risk assessments;$ the standardisation of documentation;$ initiatives to address employee behaviour as well as our health and safety culture, such as training and competitions;$ improved control of contractors; and$ increased safety inspections. Dealing with the human factorFollowing careful analysis of historic LTIs we have concluded that the primary cause of most accidents recorded at our operations is human error rather than intrinsically unsafe conditions. Behaviour we have identified that leads to injuries includes complacency, failure to follow procedures, wearing incorrect Personal Protective Equipment ("PPE"), incorrect use of equipment, failure to recognise hazards, 'poor housekeeping' and inadequate warning, amongst others. We believe that health and safety-consciousness is a way of life that needs to extend to outside the workplace.We therefore focus safety programmes on reinforcing correct, while correcting errant, behaviour. This is mostly achieved via special safety initiatives, competitions and awareness campaigns (especially over holiday periods) that all form part of the integrated health and safety programmes at operations. We supplement this with strict disciplinary measures for staff who do not adhere to procedures, ranging from mandatory retraining to, in extreme cases, dismissal.Petra's safety philosophyDespite this focus on behaviour, it remains vital to Petra to ensure that the physical conditions in which our employees work are as safe as possible. We follow a safety philosophy that recognises that if the energies at play (i.e. electrical, gravitational, kinetic, etc.) are removed, the likelihood of an accident occurring decreases dramatically. The following generic risks have been identified for special attention:$ Vehicles - Trackless Mobile Machinery ("TMMs") including light vehicles, and underground Railbound Machinery: At South African mines, it is mandatory to have Codes of Practice in place for TMMs and Railbound Machinery, due to the high incidence of accidents and injuries involving these vehicles in the mining industry. We go beyond the legal requirements and take great care to limit the risk involved with the use of vehicles by closely regulating how they come into contact with other vehicles and pedestrians.$ Guarding of machinery: Preventing access to the moving parts of machinery and the prevention of 'nip points' by the installation of proper guards on all machinery remains an important consideration in the avoidance of accidents. It is therefore also regarded to be one of the '10 Deadly Sins' (which carry heavy disciplinary sanction) to operate any machine without proper guards in place.$ De-energise and isolation/lockout: Working on machinery which is not correctly isolated or fully locked out has the potential to cause serious injuries or death. We have therefore implemented stringent lock-out procedures which are considered fail-safe if applied correctly. No work is to be performed until the energies involved (electrical, gravitational, kinetic, etc.) have been removed or locked out as far as is possible, and normal operations do not proceed until the area has been declared safe and the lock-out removed or the system has been re-energised.$ Lifting operations: Lifting operations are one of the daily activities at Petra's mines with the greatest potential for causing injury. Not only do gravitational forces present hazards of injury through falling objects and physical strains, but there is also potential for nip points developing as well as significant damage to facilities and equipment. For this reason, thorough risk assessments are performed on all lifting operations and procedures put in place to minimise the risks involved with lifting.$ Working at heights: When employees need to perform any tasks at height, the risk of injury increases. Although there are mandatory standards for any work at heights, great care is taken to optimise the conditions and procedures followed when such work is performed.All Petra's mines have well-equipped and trained emergency response teams to deal with major incidents such as fire, flooding and FOG. However, our philosophy is that 'prevention is better than cure', and all necessary systems and procedures are in place to minimise the likelihood of such emergencies occurring.Safety performance in FY 2012¹:OperationLTIFRFIFRTIFRShifts lost as a result of injuries and fatalitiesMilestones inFY 2012Cullinan0.280.003.02206Finsch 0.580.001.951341 million FFSKoffiefontein1.790.002.24 327Kimberley Underground1.150.137.55449Helam0.850.0013.261127,000 FFPSSedibeng4.820.0013.759478,000 FFPSStar5.720.005.72846,000 FFPSWilliamson0.000.3520.35 17Three years without an LTI to March 2012Group,276Notes:1. The safety statistics above include all permanent employee and contractor incidents.2. In FY 2012, a traffic accident occurred within the Williamson mine lease perimeter, involving two contractors from Zenith Security Services; one of the two was seriously injured and the other very sadly passed away. The accident was reported to the local authorities. Whilst the accident is considered to be the responsibility of the direct employer (i.e. the contractor) according to local law, the Williamson mine carried out its own investigation into the matter.

Petra Diamonds Limited Sustainability Report 201221HEALTH AND SAFETYHealth and SafetyInstilling a safety culture continuedOccupational illnessesWe have stringent occupational illness policies in place across our operations in line with our objective of recording zero harm. However, the nature of our operations and the long latency of many occupational illnesses means that monitoring plays a key role in addressing these issues. All formal agreements with trade unions at our mines include provisions relating to occupational health and safety (apart from at Kimberley Underground where such an agreement is currently being negotiated). Each South African operation has a formal management-worker committee which provides input into occupational health and safety programmes, whereas Williamson in Tanzania has an informal system whereby the mine's HSE representatives forward matters for consideration at the senior safety committee meetings.The major causes of occupational illnesses at our operations are noise induced hearing loss ("NIHL"), respiratory illnesses, and injuries resulting from repetitive activities.Our approach to tackling these issues is based on rigorous ongoing monitoring of individuals and workplaces, as well as the provision of PPE in the case of NIHL and respiratory illnesses. We have a particular focus on reducing NIHL, in line with South African Mine Health and Safety Council targets. Focusing on employees most exposed to noise, we undertake regular testing of employees and contractors at risk of NIHL and investigate any shifts in which noise levels exceed set levels. In addition we have issued improved hearing protection equipment to affected staff and provided additional training. We recorded seven new cases of occupational illnesses during FY 2012, comprising five cases of NIHL, one case of respiratory illness and one case of occupational dermatitis. In addition, most of our operations have wellness programmes in place for staff which focus on issues such as diabetes, alcohol and drug usage, obesity, hypertension, mental health and other possible personal health problems that could affect our employees.CommunityThe key community health issues which impact our operations are HIV/AIDS, tuberculosis and, at the Williamson mine, malaria.HIV/AIDSHIV/AIDS is a significant risk to our workforce as well as to the long-term health of our host communities. We have robust plans to manage this risk at our operations and are in the process of developing a Group wide HIV/AIDS policy.We devote significant resources to tackling the problem and during FY 2012 we conducted more than 6,000 examinations of employees and dependents.We provide Voluntary Counselling and Testing ("VCT") and Anti-Retroviral Treatment ("ART") free of charge to all employees and dependants. More than 1,600 employees underwent VCT during FY 2012, 187 individuals were registered on our Chronic Disease Management Programme and 40 were placed on ART. Throughout the Year we undertook a number of initiatives at our operations to increase awareness and understanding of HIV/AIDS. These included: $ campaigns at our operations to promote uptake of VCT amongst employees and dependents; $ provision of condoms; and$ educational and awareness programmes to dispel myths about the disease and fight discrimination.We also work closely with trade unions and NGOs at a number of operations to improve the delivery of our HIV/AIDs treatment and prevention programmes. TuberculosisThe link between HIV/AIDS and tuberculosis is well known and we provide testing and counselling for tuberculosis at a number of our operations. Tuberculosis is completely curable and we have implemented the internationally recommended Directly Observed Treatment Short Course Strategy at our South African and Tanzanian operations. We recorded five new cases of tuberculosis at our operations during FY 2012.Malaria and waterborne diseasesMalaria is a significant health issue at the Williamson mine in Tanzania, representing 17% of all reported illnesses at the nearby Mwadui village hospital. Williamson has put in place a plan to control mosquitos through the rehabilitation of disturbed land that offers breeding places and has provided mosquito nets in cooperation with Government programmes.Waterborne diseases such as dysentery and typhoid are also a significant issue in the communities around Williamson. The mine's water treatment plant provides clean water to the operation and to Mwadui village and other surrounding communities via established potable water points. In addition, all water sources, dams and discharge ponds undergo quarterly testing. Mwadui Hospital at WilliamsonThe Williamson mine is based in Mwadui, a rural town southeast of Mwanza in the Shinyanga region of northern Tanzania. The Mwadui Hospital was established by the Williamson mine in the 1950s to provide comprehensive medical services free of charge to Williamson employees and their families. In addition, the hospital also services members of the surrounding community at a nominal cost. The Mwadui hospital, which Petra owns and operates, is the only hospital in the Kishapu district where the Williamson mine is located and is fully equipped for small to medium surgical procedures and includes a pharmacy, reproductive health facility, outpatient department, laboratory, X-ray and mortuary. The facility services between 400 and 600 people on a monthly basis. In addition, the hospital has been designated to pilot various health programmes in conjunction with the Tanzanian Government and the relevant NGOs. The programmes include mother and child health, malaria prevention, VCT and ART. These services are provided free of charge to Mwadui and the contiguous communities.The Mwadui hospital at Williamson services between 400 and 600 people on a monthly basis
