Occupational safety and health in industries significantly affects the health of employees. This research based on OHSAS 18001 of British Standards Institution, a Delphi panel of 18 members including government sector, academic and research units, companies, certification companies and private sector was invited to take on a questionnaire investigation. Finally <||>an Occupational Safety and Health Assessment Indicators of Various Industries<||> including five dimensions and 70 indicators were set-up. 800 questionnaire copies were issued to related division chiefs and copies were recovered at valid recovery rate of 20.3%. From the results, 63.8% of chiefs of the enterprises having ISO 14001 were willing to introduce OHSAS 18001, although only. 38.3% of companies did have the certification; though one quarter of the enterprises still needed certification of OHSAS 18001. The main reason of failing to introduce OHSAS 18001 was <||>not required by laws<||> (40.8%), followed by <||>lack of marketing demand<||> (38.0%). Based on the investigations of specialists and enterprises' heads, the importance of every indicator dimension was general evaluated above 'importance' degree (i.e. the policy was feasible); easiness of execution was evaluated between 'ordinary' and 'easy' (i.e. both technology and economy were feasible), all mentinoned above showed that OHSAS 18001 was further promoted on the companies already having ISO 14001 was feasible. And the indicator dimention of <||>occupational safety and health policies<||> was the most one among five ones for importance, easiness of execution, executability and current execution status. On the other hand, enterprise heads thought that among the four major industries, high tech industry had the most indicators should to be executed, which accounting for 85.7%; then followed by heavy industry, accounting for 81.4%. Both light industry and service industries had the best execution current status.
