Question 1 of 27070

Q

How many portable fire extinguishers are required in the machinery space of a 260 GT towing vessel with 2400 B.H.P.?

🔍 Key Concepts

• 46 CFR Subchapter M requirements for towing vessel fire protection • How gross tonnage (GT) and total brake horsepower (B.H.P.) affect the number and size of required portable extinguishers in machinery spaces • Differences between B-II and the post-2016 40-B:C rating, and why they’re listed together

💭 Think About

• First, identify the correct table in 46 CFR that specifies the minimum number and type of extinguishers for towing vessel machinery spaces based on GT and horsepower—what row and column would a 260 GT, 2400 B.H.P. vessel fall into? • Ask yourself whether the regulation cares more about total horsepower, number of propulsion engines, or just the fact that it’s a machinery space on a towing vessel of this size. • Compare what the table shows for vessels just below and just above 260 GT / 2400 B.H.P.—does the required number of B-II extinguishers jump at a particular threshold?

✅ Before You Answer

• Verify you are looking at the correct CFR table for towing vessels (Subchapter M), not fishing or passenger vessels. • Confirm whether the requirement is for B-II size (or 40-B:C equivalent) and not a mix of sizes. • Double-check that the number you pick matches the machinery space requirement, not accommodation or galley spaces.
