SMIC’s Shanghai site first attained OHSAS 18001 (Occupation Health and Safety Assessment Series) certification from the British Standard Institute in September 2003; subsequently, all other sites also received OHSAS 18001 certification. SMIC's safety and health management is based on the framework of the OHSAS 18001 management system, and uses information technology to continually improve our "Plan-Do-Check-Act" (P-D-C-A) cycle to prevent accidents and improve employees' safety and health.
