Question 829 Deck Safety

The correct answer is C. Carbon dioxide (CO2) is considered a fire extinguishing agent and is included in the list of approved extinguishing agents for use on board vessels. CO2 is an effective fire extinguisher because it displaces oxygen, thereby depriving the fire of the necessary element to sustain combustion. This makes CO2 a suitable choice for extinguishing fires on vessels where the risk of electrical or flammable liquid fires is present. The other options (A, B, D) are incorrect as they do not accurately describe the role of CO2 as a fire extinguishing agent on board vessels.
