In this article, we will explore in detail the nine classes of dangerous goodshighlighting their importance and the necessary precautions for their transportation.



What is considered dangerous goods

Dangerous goods are materials or products that, due to their chemical or physical properties, may pose a risk to health, safety, property or the environment. The classification of these goods is crucial to ensure proper and safe handling, especially during the
transport of dangerous goods by road

International regulations, such as those of the UN, establish nine main classes of dangerous goods, each with its own characteristics and handling requirements.

Class 2: Gases

Gases can be flammable, non-flammable or toxic. This class ranges from domestic gases such as propane to industrial gases such as chlorine. Gas cylinders should be handled with care to avoid leaks and explosions.

Class 3: Flammable liquids

This class includes liquids that emit flammable vapors at relatively low temperatures, such as gasoline, alcohol and paints. Flammable liquids are common in various industries, making their safe handling essential to prevent fires and explosions.
