🔍 Key Concepts

• USCG fire extinguisher size classifications using Roman numerals (I, II, III, IV, V) • Difference between hand-portable, semi-portable, and fixed fire-extinguishing equipment • Where smaller extinguishers are typically located and how they are operated by one person

💭 Think About

• Think about which types of extinguishers are intended to be carried and operated by a single crew member without mechanical assistance. • Consider which types of extinguishing systems are permanently installed versus those that can be moved around the vessel. • Ask yourself: on small boats and around machinery spaces, what size and type designation is usually stamped on the label of the loose, carry-around extinguishers?

✅ Before You Answer

• Verify how the Coast Guard defines portable vs. semi-portable vs. fixed fire extinguishing equipment in 46 CFR. • Check which Roman numerals (I–V) are associated with units that can be lifted and used by one person. • Confirm that fixed systems are not labeled only by small Roman numerals, but by system type and protected space.
