Project DescriptionTraining, discussions and reviews will include operations, maintenance, shipping/receiving,purchasing, and contractors at the planning, operations and closure stages of the project. MaterialSafety Data Sheets (MSDS) and the Workplace Hazardous Material Information System(WHMIS) will be utilized to screen and classify materials.Hazardous materials and wastes require special handling and training procedures. All employeeswill be provided with training under the umbrella of the WHMIS system so that they can identifyhazardous materials; know how to obtain appropriate information on special handling proceduresrequired, i.e., know where MSDS are to be found and how to read them; precautions required andprotective equipment required; know how to label and package hazardous materials and wastes;know where and how hazardous wastes are to be stored; and how wastes are to be disposed of.Records of completion of WHMIS training will be kept for all employees.Employees who are tasked with receiving, off loading and storing potentially hazardous materialsor involved in the storage and shipment off-site of hazardous wastes will receive hazardousmaterials handling training. This training will be directed at ensuring that appropriate employeesknow how hazardous materials are to be packaged, handled and labelled during transport andduring storage. Similarly this training will be directed at ensuring that appropriate employeesknow how to package, label and ship hazardous wastes including proper record keeping andmanifesting.2.6.7 EquipmentTable 2.6-1 presents a list of the production equipment required on site. Major equipmentreplacements were not required with the 14 year mine life due to the declining ore requirementsas the mine matures which results in declining equipment hour requirements.One 18 m 3 hydraulic excavator was chosen as the primary waste mining unit with a 17 m 3 frontend loader as the back up. The front end loader is the primary ore loading unit. The haulage fleetwas designed to be 180 tonnes in carrying capacity.Mining has been scheduled to occur 360 days a year, 24 hours per day.2.7 Waste and Water Management2.7.1 Tailings Management FacilityThis section describes the basic design, construction, operation and closure concepts for theTailings Management Facility (TMF).2.7.1.1 Site SelectionThe site of the TMF has not been finalized. An alternative assessment process is under way tofinalize selection of the optimum site in terms of volumetric considerations (ratio of storagevolume to dam volume), proximity to the process plant, and aquatic impacts.January 2008 Hackett River Project – Project Proposal Sabina Silver CorporationReport Version B.1 2–30 Rescan Environmental Services Ltd.
