Which UN hazard class includes explosives?

The United Nations (UN) hazard class that includes explosives is Class 1. This classification specifically pertains to materials and items that are considered explosives, including a variety of substances that can produce an explosive effect under certain conditions. Class 1 is further divided into several divisions that address different types of explosives, such as those that are used in military applications, blasting agents, and pyrotechnics.

Understanding the classification system is crucial for anyone working with hazardous materials, as it helps in identifying the potential risks associated with different substances and ensures the proper handling, packaging, and transportation measures are taken to mitigate any dangers. In contrast, the other classes relate to other types of hazardous materials, such as gases, flammable liquids, and solids, which do not encompass explosives. This highlights the specificity of Class 1 in addressing the unique hazards posed by explosive materials.
