How many classes of dangerous goods are there?

The classification of dangerous goods is based on the criteria set by various regulatory bodies, and according to the United Nations, there are nine distinct classes of dangerous goods. These classes categorize materials based on their specific hazardous characteristics, ensuring proper handling, transport, and storage.

The first class is for explosives; the second class includes gases; the third pertains to flammable liquids; the fourth covers flammable solids; the fifth class encompasses oxidizing agents and organic peroxides; the sixth class is for toxic and infectious substances; the seventh class is designated for radioactive materials; the eighth class includes corrosive substances; and the ninth class is a catch-all for various other dangerous goods that do not fit into the previous categories.

This classification system is crucial for ensuring safety in transportation and handling, as different classes require different safety measures and precautions. Therefore, recognizing that there are nine classes is essential for anyone involved in the shipping or handling of dangerous goods.
