Waihi Gold operates a CARDAX system and all visitors and uninducted persons must sign in and out at Security every time they come onto site. Visitor management liosks (tablets) are located at Moresby Ave and Baxter Rd Security, and require the visitor to complete a short induction. Underground visitors will also be required to be logged in via the visitor’s book located in the Technical Services / Reception area. They will also be tagged on with their allocated Underground guide and documented on the Visitors Guide sign on sheet. 10.7.1 Methods of accounting for personnel Waihi mine operation is spread out over a large area. To ensure all personnel on site can be accounted for, the following personnel accounting methods are used at Waihi: • CARDAX – an electronic card system used to enter all active mining areas. This requires an authorized access card to enter these locations. A report can be run from various locations which will identify where and when personnel have entered the mining areas. • Underground areas have a sign in and sign out book located at the Amenities building Reception area. This is to capture any personnel who may be visiting or authorized for a short term visit to site. • Shift attendance sheets – all crews are required to sign in as present on arrival to their mining area. • Underground tag board. • Deployment sheets with locations and activities for the current shift. Dependent on the situation a combination of the above accounting methods may need to be implemented. 10.7.2 Employee Emergency Contact Records All employment records are kept in the HR management data base complete with details of emergency contacts for all employees working at Waihi mine sites. Contractors are required to have a contactable representative that will advise Waihi personnel of emergency details of their workers. Contractor emergency details are also stored in the Site Cardax system with their induction records. 10.7.3 Trial Evacuations Trial evacuations are to be conducted periodically to test the Emergency response plan and to ensure that employees have an understanding of their requirements. These trial evacuations are to be recorded on the “Trial Evacuation Report” and all debrief notes included. Any corrective actions that result from this process are to be entered into INX. 11.0 EMERGENCY RESPONSE CAPABILITIES Waihi Operation has set up its own emergency response capabilities to respond in an emergency situation.
