This standard replaces HG 20660-2000 The Grades of Toxicity Harm and Explosion Danger of Chemical in Pressured Vessels from the implementation date hereof. The standard drafting group has revised this standard through the extensive investigation and study, careful summarization of practical experience, reference to new laws, regulations and relevant standards and codes, and on the basis of widely soliciting for opinions. The main technical contents of this standard are: general provisions, terms and symbols, basic requirements, classification for hazard of toxicant, classification for hazard of explosive (5 clauses in total) as well as annexes and explanation of provisions. The following main changes have been made with respect to HG 20660-2000: ① the clause “application scope” is revised and merged into the clause “general provisions”; ② the clause “terms and symbols” is added; ③ the clause "basic requirements" is added; ④ the clause “classification principle” is revised and divided into two clauses, i.e., classification for hazard of toxicant and classification for hazard of explosive. The quantity and content of classified chemical media are added; ⑤ the former Annex A “basis for classification for hazard of toxicant” is deleted; ⑥ the former Attached Table 1 is changed to Annex A “Classification data sheet for hazard of toxicity of chemical mediums”. ⑦ the former Attached Table 2 is changed to Annex B “Data sheet of hazard of explosion in chemical mediums” This standard is proposed by and under the jurisdiction of China Petroleum and Chemical Industry Federation.

A.0.2表A.0.1中化学介质的分类分级评分依据见表A.0.2。表A.0.1中化学介质的毒物危害指数的计算按A.0.2公式计算。表A.0.1中化学介质的最后定级采用毒物危害指数(THI)数值与国家的产业政策相结合的方法。 (A.0.2) 式中： THI——毒物危害指数； ki—分项指标权重系数； Fi——分项指标积分值。 化学介质毒性危害程度的最后定级采用毒物危害指数数值与国家产业政策相结合的方法。 轻度危害(Ⅳ级)：THI<35； 中度危害(Ⅲ级)：THI≥35~<50； 高度危害(Ⅱ级)：THI≥50~<65； 极度危害(I级)：THI≥65。 根据IARC致癌性分类确认为人类致癌物(G1组)的，直接定为I级(极度危害)。 列入中国政府禁止使用名单的物质，直接列为I级(极度危害)。 列入中国政府限制使用(含贸易限制)名单的物质，毒物危害指数低于高度危害分级的，直接列为Ⅱ级(高度危害)；毒物危害指数在极度或高度范围内的，依据毒物危害指数进行定级。 |
