SAFETY PERFORMANCE

We are committed to meeting the highest standards of corporate citizenship by protecting the health and safety of our employees.

Safety is critical to our corporate values and a key component of operational excellence. An injury free workplace sends our people safely home to their families and friends. We strive to create a working environment where accidents do not occur and in which employees, contractors and the public are not exposed to health and safety hazards. Good safety performance also delivers economic benefits. Our workforce is more productive, with fewer days lost to injury. Fewer injuries also result in lower insurance and workers’ compensation premiums. A safe workplace is also more attractive to prospective employees and contractors.

Where we have operational control, we have implemented standards, practices and plans to communicate our safety expectations and guide our activities. We continue to improve our safety processes and procedures, conduct regular inspections of our facilities and have well developed incident reporting and emergency response systems. We emphasize training and competency within our workforce and promote communication through regular safety meetings, work permitting processes and internal reporting.
