🔍 Key Concepts

• 46 CFR 25.30-20 – Fire extinguishing equipment required on uninspected vessels • How required extinguishers change with total brake horsepower (B.H.P.) in machinery spaces • Difference between B-I and B-II hand portable extinguishers and how they are counted

💭 Think About

• Locate the correct horsepower range in the CFR table that includes 1,400 B.H.P. and see what it specifies for machinery spaces on towing vessels. • Ask yourself whether the table is asking for total number of extinguishers of a certain type, or a combination of sizes that together meet the requirement. • Compare what is required just below 1,400 B.H.P. and just above it to understand how the regulation scales with increasing horsepower.

✅ Before You Answer

• Verify you are in 46 CFR 25.30-20 and in the row for ‘Towing vessels (uninspected)’ or equivalent category, not passenger or inspected vessels. • Confirm that you are reading the column for B-II hand portable extinguishers in machinery space, not fixed systems or other locations. • Double-check that the B.H.P. range you select actually includes 1,400 B.H.P. and that you are not using a range that tops out below or starts above 1,400.
