Navigating Hazards: The Classes of Dangerous Goods

In the logistics industry, having a comprehensive understanding of dangerous goods is paramount for professionals involved in transportation, storage, and handling operations. Dangerous goods, also known as hazardous materials, encompass substances and articles that possess inherent risks and hazards during their transportation. Knowledge about dangerous goods and their classification is crucial for logistics professionals to ensure the safety of individuals, protect the environment, and safeguard property.

Transporting and handling dangerous goods without proper knowledge and adherence to regulations can have severe consequences, including accidents, injuries, environmental damage, and legal repercussions. Therefore, it is essential for logistics professionals to be well-versed in the nature of dangerous goods, their classification, and the associated precautions and procedures.

Classes of dangerous goods

Dangerous goods are classified into different classes based on their specific propertiesand associated hazards. The United Nations (UN) has developed a classification system that is widely used internationally. The classes of dangerous goods are as follows:

Class 1: Explosives

Substances and articles that have the potential to cause an explosion.

Divided into six divisions based on their characteristics and risks.

Class 2: Gases

Compressed,liquefied, or dissolved gases that can be flammable, toxic, or asphyxiating.

Divided into three divisions:

  • Flammable gases
  • Non-flammable gases
  • Toxic gases.
Class 3: Flammable Liquids

Liquids with a flashpoint below a certain temperature that can easily ignite and sustain a fire.

Examples include gasoline, alcohol, and certain solvents.

Class 4: Flammable Solids

Substances Liable to Spontaneous Combustion; Substances that Emit Flammable Gases When in Contact with Water

Divided into three divisions:

  • a) Flammable solids: Solids that can readily ignite under normal conditions.
  • b) Substances liable to spontaneous combustion: Substances that can ignite spontaneously without an external ignition source.
  • c) Substances that emit flammable gases when in contact with water: Substances that can release flammable gases when they come into contact with water.
Class 5: Oxidizing Substances and Organic Peroxides

Divided into two divisions:

  • a) Oxidizing substances: Substances that provide oxygen and support combustion.
  • b) Organic peroxides: Compounds that can release oxygen and are prone to self-reactivity and combustion.
Class 6: Toxic and Infectious Substances

Divided into two divisions:

  • a) Toxic substances: Substances that can cause harm or be lethal when exposed to living organisms.
  • b) Infectious substances: Substances containing pathogens (such as bacteria, viruses, or fungi) that can cause disease in humans or animals.
Class 7: Radioactive Materials

Materials that emit ionizing radiation and require special precautions for their handling, storage, and transport.

Class 8: Corrosive Substances

Substances that can cause damage to living tissues or corrode materials they come into contact with, such as acids and alkalis.

Class 9: Miscellaneous Dangerous Substances and Articles

Substances and articles that possess dangerous properties but do not fall under the previous classes.

Examples include lithium batteries, environmentally hazardous substances, and elevated temperature substances.

Each class of dangerous goods has specific packaging, labelling, and handling requirements to ensure safe transportation and storage. It is essential to adhere to these classifications and associated regulations to mitigate risks and protect people, property, and the environment.
