When are placards required for Table 1 commodities?

Placards are required for Table 1 commodities regardless of the quantity being transported. Table 1 commodities are classified as those that pose significant hazards due to their nature, such as highly toxic substances or materials that may react vigorously. The requirement for placarding at all amounts highlights the potential severity of risks associated with these materials, ensuring that emergency responders and others can recognize the presence of hazardous materials immediately.

This blanket requirement emphasizes the importance of communication in hazardous material transportation. By mandating placards for every amount, it ensures that the risks are clearly marked, allowing for proper handling and emergency response measures to be in place.

In contrast, there are specific regulations for Table 2 and other commodities where placards become necessary only at certain weight thresholds, such as above 1001 lbs or when mixed with other materials. Thus, Table 1’s stipulation for placarding all amounts underlines the heightened risk these materials present in any quantity.
