How is a material classified as a hazardous material?

A material is classified as a hazardous material based on its potential to pose a risk to health, safety, or property during transportation. This classification is essential because it helps in identifying substances that, when transported, could cause harm to people, the environment, or property if not handled, stored, or transported properly.

For example, hazardous materials can include flammable liquids, toxic substances, corrosive materials, and explosives. The key factor in this classification is the inherent properties of the substances and their effects on human health and safety, rather than factors like cost, common usage, or quantity.

Materials that are classified as hazardous require specific handling and packaging requirements, labeling, and documentation to ensure safety throughout the transport process. This is crucial for minimizing risks and ensuring that emergency responders can effectively manage incidents involving hazardous materials.
