 ABOUT THE PT INCO MAJOR HAZARD STANDARDS

These Standards are designed to address the major safety hazards at PT Inco. For each major
hazard they define the full range of available controls that could be implemented to address all
aspects of the hazard in the context of industry best-practice.

Compliance with these Standards comprises a long-term management goal for the site, as does our
commitment to zero injury for all workers. It is not expected that all areas of operation could be in
complete compliance with all aspects of each Standard, just as it is not expected that all risk can be
eliminated from any mining and processing operation.

However, the concept of best practice includes a commitment to ongoing improvement, and these
Standards provide a means of measuring and guiding that progress. A baseline audit will be
conducted in 2006 to measure compliance with all 18 Major hazard Standards, and this in turn will
form the basis for improvement plans in all Departments that will result in progressive reduction of risk
of injury from accidents.

Standar ini dirancang untuk mengatur bahaya keselamatan utama di PT Inco. Untuk tiap bahaya
utama yang sudah mempunyai pengendalian dengan jangkauan penuh yang dapat diterapkan untuk
mengatur semua aspek bahaya dalam konteks praktek-praktek terbaik dalam industri.

Pematuhan terhadap standar ini terdiri dari tujuan manajemen jangka panjang di lokasi, sebagaimana
halnya komitmen kami untuk menuju nihil cidera bagi pekerja. Tidaklah diharapkan bahwa semua
area operasi dapat seluruhnya mematuhi semua aspek dari setiap standar, sebagaimana yang tak
diharapkan bahwa semua risiko dapat dieliminasi dari setiap operasi penambangan dan pengolahan.

Namun demikian, konsep tentang praktek-praktek terbaik termasuk merupakan suatu komitmen
untuk terus menerus mengupayakan peningkatan, dan Standar ini memberikan suatu cara untuk
mengukur dan memberikan pedoman kemajuan itu. Suatu audit sebagai garis dasar akan dilakukan
pada tahun 2006 untuk mengukur kepatuhan terhadap seluruh 18 Standar Bahaya Utama, dan ini
pada gilirannya akan membentuk suatu basis dalam melakukan peningkatan yang bakal memberikan
hasil pengurangan secara progressiv terhadap risiko cedera yang terjadi akibat kecelakaan.
