Your vessel is carrying a cargo of Methyl Ethyl Ketone (MEK), which has caught fire. Which extinguishing agents should be used?

Correct Answer: Option C — Carbon dioxide, dry chemical, or alcohol foam.

Methyl Ethyl Ketone is a polar solvent that dissolves standard protein or aqueous film-forming foams. Alcohol-resistant foam is specifically engineered to form a protective polymeric membrane over the fuel surface, preventing the solvent from breaking down the foam blanket. Carbon dioxide and dry chemical are also effective.
