What term is used for a container on a tank vehicle that carries flammable liquids with a capacity of at least 450 liters?

The term that specifically refers to a container on a tank vehicle designed to carry flammable liquids with a capacity of at least 450 liters is "Cargo Tank." This terminology is commonly used in regulations and standards related to transporting hazardous materials, including flammable liquids. Cargo tanks are engineered to handle the risks associated with transporting dangerous goods, ensuring the safety of both the transport vehicle and the surrounding environment.

Cargo tanks are designed with specific features like pressure resistance, venting systems, and often specialized lining materials to prevent leaks and spills. This ensures compliance with safety regulations and helps mitigate the potential impact in the event of an incident.

In contrast, a fuel tank typically refers to a reservoir for fuel, which can be found in various vehicles and machinery, but does not necessarily conform to the specifications of a cargo tank intended for transport. A storage tank is generally a large stationary container for storing liquids but isn't necessarily associated with vehicles or the transport of hazardous materials. A transport vessel is a broader term that can refer to any means of transporting goods, including ships, trucks, or planes, and does not specifically denote the characteristics required for a container used in the transport of flammable liquids.
