What placard should be used with an inhalation hazard load?

The correct placard for an inhalation hazard load is the poison placard. Inhalation hazards are substances that can cause serious health effects when they are inhaled, and they often fall under the classification of toxic materials. The poison placard is specifically designated for these types of hazardous materials, indicating a significant risk to human health through inhalation exposure.

Using the poison placard alerts drivers, handlers, and emergency responders to the potential dangers associated with the load, enabling them to take appropriate precautions when transporting or responding to incidents involving such materials. The visual cue provided by the poison placard is widely recognized and helps ensure safety measures are effectively enacted during the transportation process, thereby highlighting the importance of proper labeling in hazardous materials management.
