Which type of fire extinguishers are permitted on inspected vessels?

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

Answer: (D)

On inspected vessels, portable fire extinguishers must be Coast Guard–approved or listed by a recognized testing laboratory. A variety of extinguisher types are allowed because each type serves different fire scenarios that could occur on a boat. Foam extinguishers are effective for fires involving ordinary combustibles and flammable liquids, carbon dioxide extinguishers work well in enclosed spaces and on electrical fires where a clean discharge is needed, and dry chemical extinguishers (often ABC) mix versatility by handling Class A, B, and C fires. Because all three types are commonly approved for marine use and can be maintained to meet the vessel’s fire safety plan, all of these types are permitted on inspected vessels as long as they are properly maintained and appropriately located.
