Question 279 Deck General

70% to pass

Your containership has a container displaying a hazardous cargo placard. The placard has the number 2199 on it. This indicates that it is carrying what cargo?

A Adiponitrile
B Xylenol
C Furan
D Phosphine
AI Explanation

The correct answer is D) Phosphine. The placard number 2199 corresponds to the United Nations (UN) identification number for phosphine, which is a flammable, toxic gas used as a fumigant and in the production of other chemicals. According to the Hazardous Materials Table in the Code of Federal Regulations (49 CFR 172.101), the placard number 2199 is assigned to phosphine. The other answer choices (A, B, and C) do not match the placard number 2199 and therefore are incorrect. Adiponitrile, xylenol, and furan have different UN identification numbers that would be displayed on the placard.
