Catastrophic hazards management

We recognise the exceptional nature of such events and have developed specific programmes to actively identify, monitor and mitigate catastrophic hazards within our industrial business. We review our management of catastrophic risks to understand whether they are adequately controlled. We require our industrial assets to put in place appropriate management and mitigation measures. 

Our approach supports consistency across the business for the identification and management of catastrophic hazards, according to leading practice. Our HSEC&HR policies and standards address the catastrophic hazards that present a material risk to our operations, setting out the requirements for the prevention of potentially catastrophic events. 

Catastrophic incidents may arise due to natural causes (flood, earthquake, drought) or due to infrastructure or equipment failure (tailing storage facility failure), or both. Climate change will increase physical risks to our assets and related infrastructure, largely driven by extreme weather events and water-related risks such as flooding or water scarcity.

We identify and manage catastrophic hazards through:

• A five-point risk scale: We classify the severity of potential incidents on a five-point scale from 1 (negligible) to 5 (catastrophic) – and seek to control the potential causes of catastrophic hazards at all times.
• Group fatal hazard protocols (FHPs): Our FHPs provide mandatory requirements to manage common fatal hazards at our industrial assets. Our Safety Standards provide mandatory requirements to manage fatal and/or catastrophic hazards that exist in selected industrial assets. 
• Risk register: We require all our industrial assets to maintain a register of potential catastrophic hazards and to conduct regular verification of the implementation of critical controls, which our industrial commodity departments and Group HSEC&HR review through quarterly reporting.
• Assurance: Group Internal Audit and Assurance’s (GIAA) internal audit programme considers management of our catastrophic hazards and critical control management, using experienced internal and external expert assessors. The Board HSEC Committee reviews the results of these audits, together with their key findings, observations, and recommendations for good practice, as well as the corrective actions implemented by the industrial assets to strengthen their management of the identified risks.
• Monitor: our industrial commodity departments monitor, through to closure, actions for controlling catastrophic hazards that are identified by the GIAA team during their audits. This team returns to the industrial assets 12 to 18 months later to verify that the findings are substantively addressed and that any identified corrective actions have been closed effectively. Our Board HSEC Committee reviews the status and results of these reports.

We plan, design, construct, operate, maintain and monitor our surface and underground mines, water and tailings storage facilities, smelters, refineries and other infrastructure and equipment in a manner consistent with leading international guidelines and standards,  such as the Canadian Dam Association and Global Industry Standard for Tailings Management (GISTM). Our approach is designed to prevent incidents and protect our people, assets, communities, the environment, and other stakeholders.

Our industrial assets regularly assess their need for emergency equipment, facilities and other resources against their HSEC risk register. We require emergency response preparedness through various measures, including:

• The appointment, training and equipping of rescue teams;
• Procedures for responding to specific emergency situations;
• The provision of firefighting equipment as required by the risk assessment;
• A first aid management plan supported by appropriate medical equipment and services;
• The provision of appropriate equipment to assist in rapid containment and recovery of environmental spills;
• A process for dealing with hazardous substances and dangerous goods identified as being at risk of causing an emergency on site; and
• Assets are expected to undertake an annual simulation emergency exercise to test their ERP. These include the involvement of external emergency services when appropriate.

Our TSF Framework requires our industrial assets to develop and maintain TSF-specific Emergency Preparedness and Response Plan (EPRPs) to ensure their readiness to respond in the event of a failure. The EPRP is to provide information on managing the emergency response to a potential TSF failure event that presents a risk to people and the environment. 

Each industrial commodity department (excluding oil, which does not have TSFs) has appointed an Accountable Executive and has a Responsible Person and Engineer of Record at each industrial asset. 

For all ‘Very High’ and ‘Extreme’ consequence-classified TSFs, an Independent Tailings Review Board is in place. Third-party assurance of our TSFs is undertaken by internationally recognised leading dam consultants, typically on a rolling 12- to 18-month basis.

Our online Tailings Manager Academy (TMA) develops the knowledge of our employees with TSF-related responsibilities. It was developed with the assistance of external subject matter experts. The TMA is aligned with leading industry guidelines and standards, such as the Canadian Dam Association and GISTM, and covers all aspects of tailings management, from geotechnical and hydrotechnical engineering, environmental and closure actions to emergency response planning and social performance. The TMA includes competency tests and, to support our diverse portfolio of industrial assets.

We continue to manage closed TSFs responsibly post closure. We regularly inspect our facilities, and external experts conduct independent inspections and reviews.
