SAFETY The electricity industry is an  unforgiving, potentially hazardous  environment where a single wrong  move could result in a series of  dangerous events.  To make sure every employee goes  home safe and sound, Hydro One  is committed to fostering a work  environment where health and safety  are the top priorities each and every  day. This work culture guarantees  that the right people are trained for  the right jobs. It also maintains the  safety of all Hydro One employees  and Ontarians. The aim of the 2013 Health and Safety  Performance Recognition program  was to celebrate individual and  team safety milestone achievements  throughout the Company, as well as to improve the employee health and safety performance  recognition process.  Medical attentions are defined as injuries that require treatment by a medical practitioner and are reported to the Workplace Safety and Insurance Board. The  indicator is calculated as the number  of attentions per 200,000 hours worked. In 2013, Hydro One reported 2.5 incidents per 200,000  hours worked.  Hydro One has seen a steady  decrease in both “near misses” (high  Maximum Reasonable Potential for  Harm incidents) and the number of  preventable motor vehicle accidents  year-over-year. As in previous years,  Hydro One used medical attentions as  a performance indicator to measure  its injury-free workplace goal in 2013. This is in line with the Company’s  strategic objectives and its Journey to Zero initiatives. In June 2013, Hydro One was certified  in the internationally recognized  Occupational Health and Safety  Assessment Series (OHSAS)  18001 standard. This prestigious  certification further enforces the  Company’s commitment to creating a culture of zero workplace injuries. It is also a significant milestone in our history in sustaining our world-class Health and Safety  management system.
