What is a common feature of all classes of dangerous goods?

The categorization of dangerous goods by hazard type is a fundamental principle in the transportation and handling of these materials. This classification is essential for ensuring safety and compliance with regulations. Different classes of dangerous goods, such as flammable liquids, corrosives, explosives, and toxic substances, are grouped based on their specific risks and properties. This systematic approach allows personnel to clearly understand the hazards associated with each type of material and apply the appropriate safety measures, protective gear, and handling procedures.

By recognizing the potential dangers associated with various classes, emergency responders can also act more effectively in the event of an incident, minimizing risks to life and the environment. Hence, understanding that all classes of dangerous goods are categorized by hazard type is crucial for anyone involved in the transportation, storage, or handling of these materials.
