Which tanker is designed to haul corrosives?

• A. MC 331
• B. MC 312
• C. MC 338
• D. MC 307 / DOT 407

Answer: (B)

The key idea is that corrosives require a tanker built specifically to resist chemical attack. A corrosives-rated chemical tank is designed as a non-pressurized vessel with interior lining and materials chosen to withstand strong acids and bases. That lining—often a corrosion-resistant coating or lining like glass-lined or epoxy—prevents the tank from being damaged or leaking when transporting corrosive liquids. Other tanker designs serve different purposes. Tankers intended for flammable liquids focus on safe containment of flammable vapors and may not have the corrosion-resistant interior required for acids and bases. Tanks designed for high-pressure gases or for cryogenic liquids are built for entirely different contents and pressures, not for corrosives. So the tanker best suited for hauling corrosives is the corrosion-resistant, non-pressurized chemical tanker designed for that service.
