Identify Risk Establish the Context Analyse Risk Evaluate Risk Treat Risk Communicate & Consult Monitor & Review Risk Assessment Figure 3: Waihi Risk Management Process At least once a year, and following any major incident on site or safety alert from another site or industry, a site wide risk register is reviewed and updated by department managers, technical specialists, mine safety representative and mine operators. This holistic review includes assessment of all significant risks concerning electricity at the mining operation. Each risk is given context, assigned a consequence and likelihood index and then plotted on the risk opportunity matrix. If the resultant risk ranking is not deemed satisfactory, a number of additional controls are introduced to bring the residual risk ranking down to an acceptable level. The risk register includes the following elements for each risk: • A description of the risk • A list of existing controls • The current consequence rating • The current likelihood ratings (with existing controls) • The resulting assessed current risk level • A list of future controls • The person accountable for control of the risk • A cross reference to the Action Management System (INX) for any future controls • The target consequence ratings • The target likelihood ratings
