How can you recognize hazardous materials?

Recognizing hazardous materials is primarily achieved by looking at the container's label. Labels are specifically designed to provide critical information about the contents, including the type of hazardous material and the risks associated with it. These labels are mandated by regulations, ensuring that they convey important safety information to anyone handling or near the materials.

The label typically includes hazard symbols, handling instructions, and emergency response information. This allows for immediate recognition of dangerous substances and facilitates proper precautions. While other aspects, like a driver’s behavior or the color of a container, might hint at potential hazards, they do not offer the comprehensive and specific information necessary for proper identification and safety. Similarly, the size of the vehicle can indicate a larger amount of cargo but does not specify if any of it is hazardous. Therefore, the container's label remains the most reliable source for recognizing hazardous materials.
