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?

Correct Answer: Option C — Pierce the container and discharge 6 or more portable CO2's then add more CO2 hourly.

Piercing a sealed container and discharging multiple portable CO2 units achieves local flooding without flooding the entire ship or causing extensive water damage to valuable cargo, per maritime container firefighting guidelines.
