Question 602 Deck Safety

70% to pass

A deck-stowed 40-foot container is giving off smoke, and one end is discolored from heat. The cargo is valuable and easily damaged by water. You want to extinguish the fire without further damage if possible. What action should you take?

A Connect a portable line from the ship's fixed system and discharge CO2 into the container.
B Cool the exterior of the container with water and close all vents; then keep it cooled until it can be off-loaded.
C Pierce the container and discharge 6 or more portable CO2's then add more CO2 hourly.
D Flood the container with water and disregard any cargo damage as the fire threatens the entire vessel.
AI Explanation

The correct answer is C. The reasoning behind this is that the priority in this situation is to extinguish the fire without further damaging the cargo, if possible. Discharging CO2 into the container (option A) could potentially damage the cargo, and flooding the container with water (option D) would certainly damage the cargo. Cooling the exterior of the container with water (option B) may not be sufficient to extinguish the fire. Option C, which involves piercing the container and discharging portable CO2 extinguishers, is the best approach as it allows for the fire to be extinguished without causing excessive damage to the cargo. The addition of more CO2 hourly helps to ensure the fire remains extinguished.
