Which portable fire extinguisher should be used on a class C fire on board a vessel?
AI Explanation
The correct answer is A) Carbon dioxide.
Carbon dioxide (CO2) fire extinguishers are the appropriate choice for a Class C fire, which involves energized electrical equipment. CO2 extinguishers are effective at smothering the fire without damaging the electrical components, as opposed to water-based extinguishers which could short out the equipment.
The other options are not suitable for Class C fires. Foam extinguishers (B) are meant for Class A and B fires involving ordinary combustibles. Water extinguishers (C) can conduct electricity and should not be used on energized electrical fires. Carbon tetrachloride (D) was formerly used but is now banned due to its toxicity.
