In TDG, what does the term 'dangerous goods' refer to?

The term 'dangerous goods' in TDG refers specifically to substances that pose a risk during transportation. This includes materials that can be flammable, corrosive, reactive, or toxic, and thus have the potential to harm people, property, or the environment if not properly handled and transported. Understanding this definition is crucial for ensuring safety in transport operations, as it emphasizes the importance of classifying and managing hazardous materials correctly.

In contrast, materials that have no risk to health or safety, and items that are secure in any environment do not fall under the definition of dangerous goods since they do not pose a threat during handling or transport. Similarly, goods that can be easily replaced do not inherently have any qualities that classify them as dangerous. Recognizing the specific characteristics that make some substances hazardous informs the necessary precautions for transport, including labeling, packaging, and emergency response strategies.
