Which type of extinguishers are permitted on inspected vessels?

• A. Foam extinguishers
• B. Carbon dioxide extinguishers
• C. Dry chemical extinguishers
• D. All of the above

Answer: (D)

Extinguishers on inspected vessels must be Coast Guard‑approved and suitable for the fires you’re likely to encounter at sea, covering a range of fire types. Foam extinguishers handle both flammable liquids and ordinary combustibles, making them useful in areas with engines and galley related risks. Carbon dioxide extinguishers are great for electrical fires and equipment spaces because they don’t leave residue, though they can be dangerous in occupied spaces due to oxygen displacement. Dry chemical extinguishers are versatile and effective on Class A, B, and C fires, providing broad protection. Because all three types serve different, common maritime fire scenarios and are permitted when properly approved, the correct answer includes all of them.
