Safety distance is one of the crucial methods to prevent serious accidents caused by dangerous chemical. This article analyzed domestic and international typical accidents caused by insufficiency of safety distance, compared the domestic laws, standards and requirements related to safety distance with the international counterparts, and summarized the constitutive approach for safety distance all over the world. To solve the problem that no specific standards about chemical's safety distance have been established in China and to constitute the determination method of chemical's safety distance for China, the consequence assessment method together with the consideration of the main factors affecting safety distance of chemical were employed. It will be contributive to the improvement of national chemical administration as well.
