Question 220Safety & Environmental - 1st Asst/Chief70% to pass
During onboard training with your engineers you review the various firefighting agents available for use onboard a ship. Which of the following statements describes carbon dioxide as an extinguishing agent?
AI Explanation
The correct answer is A.
Carbon dioxide is an effective extinguishing agent that can be applied through a fixed or semi-fixed system, or from a portable extinguisher. It is useful for inerting (reducing oxygen) a compartment or for putting out small local fires. This is because carbon dioxide acts by displacing oxygen, thereby depriving the fire of the necessary element for combustion.
The other options are incorrect because: B describes the properties of foam, not carbon dioxide; C describes dry chemical agents, not carbon dioxide; and D describes water mist, not carbon dioxide.
