ICMC RECERTIFICATION SUMMARY AUDIT REPORT Standard of Practice 6.2: Operate and monitor cyanide facilities to protect worker health and safety and periodically evaluate the effectiveness of health and safety measures. ® in full compliance with CC&V is: ❑ in substantial compliance with Standard of Practice 6.2 ❑ not in compliance with Summarize the basis for this finding: CC&V is in FULL COMPLIANCE with Standard of Practice 6.2 requiring the operation operate and monitor cyanide facilities to protect worker health and safety and periodically evaluates the effectiveness of health and safety measures. The operation has determined the appropriate pH for limiting the evolution of HCN gas during mixing and production activities.The operations procedures detail the importance of maintaining the solutions above pH 10 to minimize the potential for HCN gas formation.The pH levels are monitored in the control room and samples are taken with a pH monitor to confirm instrumentation is working effectively. The operation uses a combination of fixed and personal monitors for HCN level monitoring.A fixed HCN detection system, SensAlert, is in place at the operation.The monitors are located at the ADR1,ARD2, PSES,and the HG Mill.The operation also utilizes portable gas monitors, MX6 multi gas detectors,which are used the measure HCN in the person's immediate environment.They are available for use in the ADR control rooms, PSES control room, Process Laboratory, Crusher control room, Millwright shop and in the warehouse. Both the fixed and portable units alarm at 4.7 ppm low and 10.0 ppm high. CC&V has identified activities and areas where the exposure to harmful concentrations of cyanide is possible. For such activities,the operation has operating procedure, Procedure 2 for Personal Protective Equipment in place that state the PPE requirements for key activities in both standard conditions and spill cleanup/HCN/CN detox conditions. Example of conditions where a portable HCN monitor is required include, Solution> 1%,Truck Unloading, Solution Precipitate, Dry Process and H2O2 CN Detox. Example of where SCBA is required is HCN Gas> 10ppm. The operation has a procedure that dictates what personnel must do when the HCN monitor alarm sounds. The HCN monitors, both static and personal, are set to alarm at 4.7 ppm and 10 ppm.The operation has dictated the actions to be taken in the event of an alarm including actions to re-enter the area. Portable and fixed HCN monitors are maintained,tested,and calibrated as per manufacturer requirements. All fixed monitors are calibrated monthly as part of the preventative maintenance program and there is a relevant Cyanide Code Procedure.All portable monitors are calibrated when docked through an online system. Calibration records and preventative maintenance records were sighted by the Auditor. Warning signs in English have been placed where cyanide is used, advising workers that cyanide is present_ There is also a specific procedure detailing the required PPE for activities in standard and spill conditions. No smoking signs are posted throughout the operational areas. Showers, low-pressure eyewash stations, and dry powder fire extinguishers are strategically located throughout the operation in the cyanide areas.The showers and eyewash stations are checked daily and monthly and the fire extinguishers monthly. The operations labelled cyanide tanks and lines and clearly indicated by strategically placed signage that cyanide is present.Additionally, Danger Cyanide signage is located at the entrances to all facilities where cyanide is present. Safety Date Sheets(SDS),first aid procedures, and informational materials on cyanide safety were available in the language of the workforce in areas where cyanide is managed. SDSs(as part of the ERP)are located in each of the control rooms and intranet. First aid materials and information on cyanide safety is included in CC&V Mine July 28,2017 Name of FaalRfty Signature of Lead Auditor Date July 2017 Golder Report No.1663584-003-R-RevO 20 ASSOClates
