Question 1093Deck Safety70% to pass
If you are unable to stop a diesel engine by any other means, you should _______________.
AI Explanation
The correct answer is B) discharge a CO2 extinguisher in the air inlet.
If you are unable to stop a diesel engine by any other means, discharging a CO2 extinguisher into the air inlet is the correct action to take. CO2 extinguishers work by displacing oxygen, which will effectively starve the engine of the air it needs to continue running, causing it to shut down.
The other options are incorrect because securing the starting air supply valve (A) or the jacket water (D) would not immediately stop a running engine, and pulling off the distributor cap (C) would not work on a diesel engine, which does not have a distributor.
