Which tank carrier is designed to haul various chemicals whose pressures do not exceed 40 PSI?

• A. MC 307 / DOT 407
• B. MC 312
• C. Corrosives tanker
• D. MC 331

Answer: (A)

The key idea is matching the tank’s design pressure to the cargo’s pressure. Tanks built for liquids that don’t require high pressure are designed as non-pressurized or low‑pressure units, typically handling up to about 40 psi. The MC 307 / DOT 407 tank is exactly this kind of versatile, low‑pressure chemical carrier, designed to haul a wide range of liquids without pressurizing them above that 40 psi limit. High‑pressure tankers, like MC 331, are meant for liquefied gases under much higher pressures, so they aren’t appropriate for “various chemicals” limited to 40 psi. The corrosives tanker category focuses on the chemical type and often includes specialized liners and features, but it isn’t defined by a 40 psi limit. MC 312 is a low‑pressure option as well, but MC 307 / DOT 407 are the standard, broadly suitable choice for many chemicals within that pressure range.
