• 1.
Capacity: 4,000 - 45,000 gallons Pressure: 100 - 600 psi Used for: Flammable/non-flammable
gases and poisonous gases Cylindrical, non-compartmented steel or aluminum tanks with
rounded heads. They are top loading/unloading, pressure relief, and gauging located inside a
protective housing (dome) mounted on a single anyway.
, o A.
Cryogenic liquid tank car
o B.
Pressure tank car
o C.
High-pressure cargo tank
o D.
Non-pressure liquid cargo tank
Correct Answer
B. Pressure tank car
Explanation
A pressure tank car is the correct answer because it is designed to hold gases under pressure. The
given information states that the tank has a pressure range of 100-600 psi, which aligns with the
purpose of a pressure tank car. It is also mentioned that the tank has top loading/unloading,
pressure relief, and gauging features, which are common characteristics of a pressure tank car. The
other options, such as cryogenic liquid tank car and non-pressure liquid cargo tank, do not match
the given specifications of capacity and pressure.

Pressure: Low-pressure liquids (25 psi or lower). Refrigerated Contents: Liquids are typically Argon,
Ethylene, Hydrogen, Nitrogen, and Oxygen. Has a control valve that is normally located in a
compartment along the side. HAZARD class: 2.2
o A.
Compressed gas tube trailer
o B.
Cryogenic liquid cargo tank
o C.
,Cryogenic Liquid Tank Car
o D.
Low-pressure chemical tank
Correct Answer
C. Cryogenic Liquid Tank Car
Explanation
A cryogenic liquid tank car is the correct answer because it matches all the given characteristics.
Cryogenic liquids such as Argon, Ethylene, Hydrogen, Nitrogen, and Oxygen are typically
transported in this type of tank car. The pressure for these liquids is low (25 psi or lower), and they
are stored at extremely low temperatures. The control valve is usually located in a compartment
along the side of the tank car. Additionally, the hazard class for cryogenic liquids is 2.2, which
matches the given information.

, Correct Answer
A. Dry bulk cargo tank
Explanation
A dry bulk cargo tank is the correct answer because it matches all the given characteristics. It is
also known as a hopper trailer and is used to transport bulk solids such as cement, fertilizers, grain,
and other food products. It has one or more cone-shaped bins and has a capacity of up to 1,500
cubic ft. The PSI of a dry bulk cargo tank is less than 80, which aligns with the information provided.
Therefore, the correct answer is a dry bulk cargo tank.
