How are dangerous goods defined?

Dangerous goods are defined as articles or substances which may pose a hazard to health, safety, property, or the environment. This definition encompasses a wide range of materials, including chemicals, biological agents, radioactive materials, and more, that can cause harm if not handled properly. The focus is on the potential risks these goods pose during transportation, storage, and use, and is essential for ensuring appropriate safety measures and regulations are implemented to mitigate those risks.

The other options do not accurately reflect the nature of dangerous goods. For instance, stating that these goods are articles or substances posing no risk overlooks the fundamental characteristics that necessitate their classification. Similarly, restricting dangerous goods to only certain metals and chemicals fails to recognize the broad spectrum of materials categorized as dangerous based on their properties and behaviors. Finally, identifying dangerous goods solely as common household items simplifies the issue and disregards the wide range of items that can potentially be classified as dangerous.
