在纺织品的前处理与后处理中涉及许多化学品及其合成物，其中许多在GHS下都属于危险化学品，如果没有进行分类和标识在其运输与使用过程中将会有潜在的危险，为了减轻化学品对人类健康和生存环境的危害，联合国提出建立化学品统一分类和标识制度全球协调系统(GHS)，这种协调统一的系统将有利于控制和利用化学品，保护人类和自然环境。
实验结果按以下方式进行分类：对于易燃液体，闪点小于23 oC且初沸点≤35oC，归为易燃液体第I类，若初沸点>35oC，归为易燃液体第II类；23oC≤闪点≤60oC，归为易燃液体第III类；60oC< 闪点≤93oC，归为易燃液体第IV类；对于非金属易燃固体，若燃烧时间少于45秒且火焰能通过润湿区；对于金属粉末反应在 5分钟内蔓延到整个样品，则其应采用P.G. II包装；对于非金属易燃固体，若燃烧时间少于45秒且润湿区能阻挡火焰蔓延至少4分钟；对于金属粉末在10分钟内蔓延到整个样品，则应采用P.G. III包装；对于气溶胶，若气溶胶中含易燃成分≤1%，且其燃烧热<20kJ/g，此溶胶为非易燃气溶胶；若气溶胶中含易燃成分≥85%，并且其燃烧热≥30kJ/g，此溶胶为极易燃气溶胶；对于氧化性固体，属于P.G.I的测试样品与纤维素以质量比4:1或1:1混合，平均燃烧时间等于或少于KBrO3与纤维素的混合物（3:2）的平均燃烧时间；属于P.G.II的测试样品与纤维素以质量比4:1或1:1混合，平均燃烧时间等于或少于KBrO3与纤维素的混合物（2:3）的平均燃烧时间；属于P.G.III的测试样品与纤维素以质量比4:1或1:1混合，且不满足P.G. I、II标准。

Abstract:
In the former dealing with textiles after processing involves many chemicals and their compounds, many of which are in the GHS under hazardous chemicals, if not in their classification and identification process will be used to transport potentially dangerous, in order to reduce the chemicals on human health and environment hazards, The United Nations proposed the establishment of a harmonization of classification and labelling of chemicals globally coordinated system system (GHS), which harmonized system will be conducive to the control of chemicals and the protection of human and the natural environment. Experimental results by the following way classification : For flammable liquids, flash point less than 23 oC and early boiling point =35oC, categorized as Class I flammable liquid, and if early boiling point "35oC, categorized as Class II flammable liquid flash point =60oC ;23oC=, classified as Class III flammable liquid =93oC ;60oC< flash point, In section IV category for flammable liquids; For non-metallic flammable solid, if less than 45 seconds and the flames burning through moist areas; For metal powder response within five minutes spread to the entire sample, it should be used P.G. II packaging; For non-metallic flammable solids, If less than 45 seconds burning time zone and to stop the flames spreading material at least 4 minutes; For metal powder in 10 minutes spread to the entire sample should be used P.G. III packaging; For aerosols, which contain flammable ingredients =1% if aerosols, and its burning hot "20kJ/g, the sol-flammable aerosols; If aerosols containing flammable ingredients =85% China, and its burning hot =30kJ/g, for the sol very flammable aerosols; For solid oxide sexual belonging to the test samples and cellulose to P.G.I quality than 4:1 or 1:1 mix, the average burn time equal to or less than KBrO3 and cellulose mixture (3 : 2) the average burning time; The test samples are P.G.II with cellulose mixed to quality than 4:1 or 1:1, the average burn time equal to or less than KBrO3 and cellulose mixture (2:3) of the average combustion time; The test samples are P.G.III with cellulose mixed to quality than 4:1 or 1:1, P.G not meet. I, II standards.
