70% to passYour vessel is carrying a cargo of Ethyl methacrylate, which has caught fire. Which extinguishing agents should be used?
AWater, dry chemical or chemical foam.
BCarbon dioxide, dry chemical or chemical foam.
CCarbon dioxide, dry chemical, or alcohol foam.
DWater fog, dry chemical or chemical foam.
AI Explanation
The correct answer is B) Carbon dioxide, dry chemical or chemical foam. Ethyl methacrylate is a flammable liquid, and the best extinguishing agents for this type of fire are carbon dioxide, dry chemical, or chemical foam. Water is not recommended as it can cause the fire to spread, and alcohol foam would not be effective on a fire involving this type of chemical. The Coast Guard regulations specify these extinguishing agents as the appropriate choices for fires involving flammable liquids like ethyl methacrylate.
