SEE Table 1 and Table 2 for details. The pure substances and mixtures of hazardous chemicals shall be classified in accordance with the provisions of GB 30000.2, GB 30000.3, 4.1.2 The method for determining the threshold quantity of hazardous chemicals is as follows. 4.2 Identification index for major hazard installations 4.2.1 Production units and storage units in which the quantity of hazardous chemicals equals or exceeds the threshold quantity specified in Table 1 and Table 2 are considered to be major hazard installations. The quantity of hazardous chemicals present in the unit, according to the number of categories of hazardous chemicals, is divided into the following two cases. 4.2.3 For mixtures of hazardous chemicals, if the mixture is of the same hazard category as its pure substance, the mixture is considered as a pure substance and is calculated as a whole. If the mixture is not of the same hazard category as its pure substance, then according to the new hazard category, its threshold quantity shall be considered. 4.2.4 SEE Appendix A for the identification procedures for major hazard installations for hazardous chemicals. 4.3 Grading of major hazard installations 4.3.3 Grading standard of major hazard installations Based on the calculated R value, according to Table 6, the level of major hazard installations for hazardous chemicals is determined.Appendix A(Informative) Identification procedures for major hazard installations for hazardous chemicals ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
