A recon team observes a rolled-over MC 312 tank. The container most probably contains a

• A. Cryogenic liquid
• B. Nonhazardous liquid
• C. Corrosive liquid
• D. Flammable gas

Answer: (C)

The main idea here is that the tank’s design tells you what it’s built to carry. The MC-312 designation identifies a non‑pressurized cargo tank specifically used for corrosive liquids. These tanks are constructed with corrosion-resistant materials and linings to handle acids like sulfuric or hydrochloric acid, making them the most likely to be encountered in a rollover when the contents are corrosive. Cryogenic liquids require highly insulated, vacuum‑protected equipment, and flammable gases are typically carried in pressurized vessels, while nonhazardous liquids aren’t assigned to this corrosive-design tank. So, the most probable content after a rollover of this tank is a corrosive liquid.
