B) Even if the law does not require a truck to display a placard, the driver of the truck is required to carry documentation of the chemical being transported.
C) A tanker truck that displays a “Please drive carefully” placard is likely not carrying a hazardous material and should be considered safe to approach.
D) Any tanker truck or train that carries a hazardous material is required by federal law to display a warning placard, regardless of the quantity it is carrying.
Ans: B

- If you are the first unit to arrive at a scene and observe any signs suggesting that a hazardous materials incident has occurred, you should:
A) place yellow or red police tape around the danger zone and begin moving bystanders away from the scene.
B) remain upwind from the scene if possible and immediately call the hazardous materials response team.
C) don gloves, a mask, and a gown and begin moving injured patients away from the area surrounding the incident.
