The hazard class of a two-liter bottle of material is Flammable Liquid. If the description also said Poison Inhalation Hazard you should:
Answer: B
Placard the vehicle with both the POISON and hazard class placards.
Some hazard materials may require that multiple placards be displayed to identify all dangers. Any shipping label containing the warning, INHALATION HAZARD dictates that the POISON INHALATION HAZARD or POISON GAS placards be displayed along with any other identifiers for the classification of materials. The amount of material being transported does not affect the decision to display these placards.
All choices
- APlacard the vehicle POISON only if no other cargo requires it.
- BPlacard the vehicle with both the POISON and hazard class placards.
- CPlacard the vehicle POISON and remove all other placards.
Why the other answers are wrong
A. Placard the vehicle POISON only if no other cargo requires it.
Choice A is wrong because the POISON placard must be displayed along with other hazard class placards, not only if no other cargo requires it.
C. Placard the vehicle POISON and remove all other placards.
Choice C is wrong because you must not remove other required placards when POISON placards are needed; multiple placards must be displayed together.
