Question 1 of 27070

On an uninspected vessel which sizes of fire extinguishers are considered to be semi-portable?

🔍 Key Concepts

• Portable vs. semi-portable fire extinguishers on uninspected vessels • The size designation system for fire extinguishers (I, II, III, IV, V) • Which sizes are typically hand-carried vs. those that are mounted or on wheels

💭 Think About

• Which extinguisher sizes are small enough for one person to easily carry and operate by hand? • Which sizes are large enough that they are usually mounted in place or require more effort to move, but are not fixed piping systems? • Think about where the line is usually drawn between truly portable extinguishers and the larger, semi-portable units in USCG practice.

✅ Before You Answer

• Confirm how the USCG defines "portable" vs. "semi-portable" in the applicable fire protection regulations (46 CFR Part 25 / 46 CFR Part 193 as background). • Check which sizes (I–V) are most commonly listed as "portable" only, and which are grouped as "semi-portable" in tables or requirement charts. • Make sure the group you pick does not include the very smallest hand extinguishers and does not include the very largest fixed or wheeled systems.
