Your vessel is carrying a cargo of Ethyl methacrylate, which has caught fire. Which extinguishing agents should be used?

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

Ethyl methacrylate is a flammable monomer that can polymerize if exposed to heat. Chemical foam, carbon dioxide, and dry chemical are approved extinguishing agents. These agents suppress the fire without introducing water, which could potentially trigger hazardous polymerization reactions or cause the burning liquid to spread.
