Question 544 Deck General

The correct answer is B) Open-bed containers may be used to transport hazardous materials if the cargo is properly secured. The reasoning behind this is that open-bed containers are an acceptable way to transport hazardous materials, as long as the cargo is properly secured and segregated per the regulations. The other answer choices are incorrect: A) This statement about portable cargo tanks of flammable, cryogenic liquids is true, but it does not directly address the handling and stowage of containerized hazardous materials. C) A portable cargo tank containing a cryogenic liquid must be shipped on deck, but this does not apply to standard containerized hazardous materials. D) A container with tear gas would display a placard reading "Tear Gas" rather than "Irritant."
