The OZ Minerals Sustainability Standards adopted during 2008, incorporate safety and health aspects, and provide a uniform framework for managing safety and health across the company.

The development and implementation of safety management systems has occurred at each of our operations. At Century, Golden Grove, Rosebery and Sepon operations and across our exploration activities these systems are aligned with AS4801 - Occupational health and safety management systems. Our Rosebery operation has been certified to AS4801.

Safety and health audits

During 2008, OZ Minerals conducted health and safety audits at all operations. Some of these focused on management systems while others focused on fatal risk reduction.

A combination of external and internal resources, using a number of different audit protocols, was used to carry out the audits.

Rosebery was audited against AS4801 and also underwent a fatal risk audit, while Century had several fatal risk audits.

Both external and internal auditors audited Golden Grove and Sepon against the OZ Minerals Sustainability Standards.

These audits identified opportunities for improvement, which are tracked and reviewed quarterly by the Executive Sustainability Committee and the Board Sustainability Committee.

The following table summarises the different types of audits completed at our operations during 2008.
