The correct answer is: They have unique placards for specific hazards such as anhydrous ammonia

A key feature of Canadian transportation placards for hazardous materials is that they have unique placards for specific hazards, such as anhydrous ammonia. This specificity is critical in the handling and transportation of hazardous materials, as it provides immediate visual information that can aid emergency responders and personnel in identifying the materials involved. These unique placards are designed to convey important information regarding the particular risks associated with the chemicals being transported, enabling them to take appropriate safety measures and respond effectively in case of an incident. The inclusion of unique placards for specific materials allows for a more detailed risk assessment than more general hazard indications, ensuring that individuals can quickly recognize the type of hazard they may be facing. This is especially important in emergencies where identifying the substance rapidly can significantly influence the response strategy and help prevent further incidents.
