2 Electrical Engineers and Consultants perhaps not understanding all of the applicable regulations for Mines & Industrial Plants. Electricians and Electrical Contractors not up to date on regulations due to lack of upgrade training. Huge projects are putting significant demands on inspection oversight. Unapproved equipment being sold and incorporated into projects. Installations being performed that are not meeting minimum standards which affect reliability and safety OESR vmesf1.0 Electrical Safety Authority 2012 GETTING TO ZERO

3 ESA Service Review of pre tender Engineered plans and specs Field review of installation Product Approvals Advisory Services Documentation Benefit to Mines Reduce or eliminate change orders related to errors in electrical design Ensure field installation does not sacrifice design integrity Ensure that equipment is legal for use and suitable for your operation Information portal on application of Codes & Regulations Understand amount of defects being installed by Contractor and project division OESR vmesf1.0 Electrical Safety Authority 2012 GETTING TO ZERO

4 ESA Service Cold eye review of existing electrical system Plan reviews Advisory Services Code & Reg. Training CSA Z462 Product Approvals Benefit to Mines Identify deviations from minimum standards that will affect reliability and safety Ensure new proposed installations meet the Code and Regs. Ask the questions regarding elect. Maintenance and new work, eliminating rework Ensure qualified staff know how to install and maintain correctly. Improves system integrity Understanding Arc Flash and training on proper selection/application of PPE Approve equipment that is found to be unapproved OESR vmesf1.0 Electrical Safety Authority 2012 GETTING TO ZERO

5 ESA sponsored initiative within the Ontario mining community Venue bringing key electrical safety stakeholders together to: Share important safety initiatives; Share interpretation of codes and standards to improve consistency; Identify current trends, weaknesses and gaps in mining electrical safety; Drive Industry Change for enhanced Electrical Safety; Meetings held bi annually, Spring & Fall OESR vmesf1.0 Electrical Safety Authority 2012 GETTING TO ZERO

7 ESA receives data from various resources to compile this report. Ontario Coroner s Office Ministry of Labour (MOL) Office of the Fire Marshal (OFM) Workers Safety and Insurance Board of Ontario (WSIB) Canadian Institute for Health Information (CIHI) Statistics Canada At the time of writing, the Coroner s reports for 2009 and 2010 are only partially completed due to pending investigations and confirmations. Where there are discrepancies in the number of fatalities reported by MOL and ESA, ESA uses the data provided by the Coroner. Electrocution an accidental death caused by the contact with electricity. Fatality an injury resulting in a death

32 ring the investigation, ESA found: The primary conductor was within 4 m of the house. Horizontal clearance met the 2009 OESC. 5 aluminum extension ladders were set up against the house. Workers were leap frogging them as they installed the soffit. Victim attempted to move one of the extension ladders and it touched the energized primary line. He was killed instantly. Burn marks can be seen at the point of contact on the power line and ladder. No disconnection request was made by the workers or homeowner.
