What kind of compartment design do gasoline tankers under DOT 406 typically have?

Gasoline tankers classified under DOT 406 are specifically designed with multiple compartments. This design allows for the transportation of different grades of fuel simultaneously or for partial loading strategies. Each compartment is equipped with baffles to help prevent sloshing of the liquid during transit, which enhances stability and control when the tanker is in motion.

The multiple compartment design is also critical for maintaining safety. In the event of a spill or leak, having different compartments can help contain the incident and minimize environmental impact while providing flexibility in transport options. This feature is essential for meeting regulatory requirements and ensuring the safe handling of hazardous materials during transportation.

Other designs, such as round, single, or square compartments, do not provide the same level of functionality, safety, or regulatory compliance as the multiple compartment design used in DOT 406 gasoline tankers. These alternative shapes or configurations do not typically meet the specific needs for the transport of hazardous materials, emphasizing why the multiple compartment design is the correct choice for gasoline tankers.
