Question 565 Deck Safety

The correct answer is C) shut off the fuel supply. The reasoning for this is that the first and most important action in a fuel fire is to stop the fuel source. Shutting off the fuel supply will stop the fuel from continuing to feed the fire, which is the most critical step in controlling the situation. Applying carbon dioxide (A) or starting the fire pump (B) may help extinguish the fire, but they do not address the root cause of the issue, which is the continued flow of fuel. Battening down the engine room (D) could contain the fire, but does not directly address stopping the fuel source. By shutting off the fuel supply first, this allows the fire to be more easily contained and extinguished using other firefighting methods. This is the recommended first action per standard marine firefighting procedures.
