What is the standard weight of the CO2 fire extinguisher used on Coast Guard boats?

• A. 5-pound
• B. 2.5-pound
• C. 10-pound
• D. 20-pound

Answer: (A)

The five-pound CO2 extinguisher is used because it offers a practical balance between effectiveness and handling for Coast Guard boats. It provides enough CO2 to rapidly smother typical electrical or small fuel fires that are common aboard smaller vessels, while remaining light and compact enough to be carried and aimed quickly by a crewmember in cramped spaces like near engines or electrical panels. A two-and-a-half-pound unit is often too small to reliably control a fire before it grows, whereas larger units (ten or twenty pounds) are heavy, harder to maneuver in confined areas, and not as practical for quick use on a small boat. So the standard choice is the five-pound extinguisher.
