What is one characteristic of a Low Pressure Chemical Cargo Tank?

A defining characteristic of a Low Pressure Chemical Cargo Tank is that it generally has a maximum capacity of 7,000 gallons. These tanks are specifically designed to transport chemicals at lower pressures, typically not exceeding 25 PSI, which allows for a larger volume of hazardous liquid to be transported securely. The design and capacity of these tanks accommodate the lower pressures required for the safe transport of various chemical materials.

The other options describe characteristics that do not apply to Low Pressure Chemical Cargo Tanks. For instance, the statement about always being pressurized above 60 PSI contradicts the tank's purpose, which is to operate safely below that pressure. The mention of solid material transport is irrelevant since these tanks are primarily for liquids. Lastly, the shape of Low Pressure Chemical Cargo Tanks is not typically flat and rectangular; they often have a cylindrical shape to handle pressure and ensure structural integrity during transport.
