Question

In response to an incident involving a jackknifed tractor trailer, you arrive and size up the situation. From your position, you only have a side view of the tractor trailer. You know it is an:

a) MC 331
b) MC 338
c) MC 312/DOT 412
d) MC 306/DOT 406

Answer 1

The subject of this question is Physics and the grade level is High School. The correct option for the type of tractor trailer involved in the incident is MC 306/DOT 406.

Step-by-step explanation:

The subject of this question is Physics and the grade level is High School. To identify the type of tractor trailer involved in the incident, we look at the given options: a) MC 331, b) MC 338, c) MC 312/DOT 412, and d) MC 306/DOT 406. To determine the correct option, we need to understand the different classifications of tractor trailers used in the transportation of hazardous materials.

The correct option can be determined based on the codes mentioned. In this case, MC 331 refers to a trailer used to transport liquefied gases, such as propane. MC 338 is used for compressed gases, such as hydrogen. MC 312/DOT 412 is used for flammable liquids, while MC 306/DOT 406 is used for non-flammable and non-combustible liquids.

Since the question states that the incident involves a jackknifed tractor trailer, it is most likely carrying a fluid that caused the incident. Therefore, the correct option in this case would be MC 306/DOT 406, which is used for non-flammable and non-combustible liquids.
