What type of tanker is classified as MC-331?

The classification of an MC-331 tanker refers specifically to a pressure cargo tank. These tankers are designed to transport gases under high pressure, typically with a maximum design pressure of about 100 psi. They are equipped with features such as pressure relief valves and are constructed from materials that can withstand the inherent risks associated with transporting pressurized materials.

Pressure cargo tankers are distinctive in their ability to carry gases in a liquid state at elevated pressures, making them suitable for transporting materials like propane, butane, and other liquefied gases that require pressurization to maintain their liquid form. Understanding the specific classification of these tankers is crucial for firefighters, as it informs their response strategies when dealing with incidents involving such vehicles.

This contrasts with other types of tankers, such as cryogenic tankers, which are designed for transporting liquefied gases at extremely low temperatures, flammable liquid tankers that carry flammable liquids, and refrigerated tankers that transport substances requiring refrigeration. Each of these other types has unique construction, safety features, and operational protocols tailored to their specific cargo requirements.
