Which class of dangerous goods includes explosives?

The class of dangerous goods that includes explosives is Class 1. This classification specifically pertains to materials and articles that are capable of undergoing a rapid chemical reaction, leading to explosions or the production of flammable gases under certain conditions.

Explosives in Class 1 are subdivided further into different divisions that categorize them based on their characteristics and associated risks, such as whether they are stable or susceptible to detonation. This class is critical in aviation and transportation regulations, as the handling and transport of explosives require stringent safety measures to prevent accidents and ensure public safety.

In contrast, the other classes represent different types of hazardous materials: Class 2 pertains to gases; Class 3 is for flammable liquids; and Class 4 involves solids that are flammable or that may spontaneously combust. Each class addresses specific safety concerns associated with the particular nature of the goods involved, but explosives distinctly fall under Class 1 due to their inherent risk of detonation.
