What should you do if transporting flammable liquids and the label indicates a "Poison Inhalation Hazard"?

Use no placard
Placard vehicle with "POISON" only
Placard vehicle with both "POISON" and "HAZARDOUS"
Consult local authorities for placarding

The correct answer is: Placard vehicle with both "POISON" and "HAZARDOUS"

When transporting flammable liquids that also carry a "Poison Inhalation Hazard" label, correct placarding is critical for safety and regulatory compliance. The requirement to display both "POISON" and "HAZARDOUS" placards stems from the need to effectively communicate the dual hazards associated with the materials being transported. The presence of a flammable liquid indicates a risk for fire or explosion, while the "Poison Inhalation Hazard" signifies another layer of danger, particularly concerning inhaling toxic vapors. The combined presence of these hazards necessitates clear and visible warnings to inform emergency responders and others on the road about the specific risks associated with the cargo. Using both placards ensures that the vehicle's hazardous nature is fully understood, allowing for appropriate precautions by those who may come into contact with it, including emergency services in the event of an accident. Therefore, employing both "POISON" and "HAZARDOUS" placards helps promote safety and adheres to the relevant regulatory guidelines for transporting such materials.
