Introduction Organic peroxides is an important chemical raw material. In industrial production, except for a few used as oxide initiators, epoxidizers, reducing agents, and bleaching fungicides, the vast majority are used as polymerization initiators for olefinic monomers, curing agents for thermosetting resins, crosslinking agents for elastomers, and oxidants for organic synthesis. At present, there are about 70 kinds of Organic peroxides that have been industrialized abroad. In China, the development of Organic peroxides started late, and there are about 20 kinds of Organic peroxides. With the continuous development of synthetic resin industry, it is expected that the number and variety of Organic peroxides will increase significantly in the future. However, Organic peroxides is a special chemical raw material, which is flammable, explosive, easily decomposed, and extremely sensitive to heat, vibration or friction [z]. Therefore, it is necessary to understand the hazard characteristics and safety evaluation methods of Organic peroxides and take corresponding safety measures for its manufacture, use, storage and transportation
