What is the significance of placards in the Transport of Dangerous Goods?

Placards play a crucial role in the Transport of Dangerous Goods by providing a clear and immediate warning of the type of hazards that may be present. These visual indicators are essential for ensuring the safety of everyone involved in the transportation process, including drivers, emergency responders, and the general public.

By displaying specific symbols and colors associated with different types of dangerous goods, placards enable individuals to quickly recognize potential risks, such as flammability, toxicity, or environmental hazards. This not only helps in ensuring proper handling and emergency response but also assists in compliance with regulatory requirements established by transportation authorities.

In contrast, other options do not align with the primary purpose of placards. For instance, they are not intended to indicate the destination of goods, provide promotional messages, or identify shipping companies. This clarifies that while other aspects of transportation are essential, the primary function of placards is centered around hazard awareness and safety communication.
