Question 161Safety & Environmental - 1st Asst/Chief
70% to passYour vessel is carrying a cargo of Methyl Ethyl Ketone (MEK), which has caught fire. Which extinguishing agents should be used?
ACarbon dioxide, dry chemical, or water foam.
BCarbon dioxide, dry chemical, or water fog.
CCarbon dioxide, dry chemical, or alcohol foam.
DWater fog, dry chemical, or alcohol foam.
AI Explanation
The correct answer is C) Carbon dioxide, dry chemical, or alcohol foam. Methyl Ethyl Ketone (MEK) is a flammable liquid that requires specialized extinguishing agents. Carbon dioxide and dry chemical extinguishers are effective for extinguishing MEK fires, as they smother the fire by displacing oxygen. Alcohol-resistant foam is also recommended, as it is designed to work on fires involving polar solvents like MEK. The other options are incorrect because water fog and regular water foam are not recommended for MEK fires. Water can actually spread the fire, and regular foam may not be effective on the polar solvent.
