The placard on a tanker serves as an important safety feature, providing critical information about the type of hazardous materials being transported. These placards display specific symbols and color codes that indicate the nature of the cargo, such as flammability, toxicity, or radioactivity. This information is crucial for emergency responders and personnel handling the tanker, as it helps them assess risks and take appropriate safety measures in case of an accident or spill.
The hazard class of the substance being carried
The placard on a tanker carrying hazardous materials will tell you the class of the hazard (flammable, explosive, corrosive, etc). If you have access to the North American Guide or a similar reference, the placard will also tell you something a bit more specific about the identity of the hazardous material - its category, or sometimes its chemical name.

The most common radioactive product carried in a tanker is uranium hexafluoride. If I was under a tank of this, I would put four placards on it: radioactive, corrosive, dangerous when wet and inhalation hazard. Technically all you need is the first two, but you could put the other two on and still be okay.
