🔍 Key Concepts

• 46 CFR fire protection requirements for towing vessels under 100 gross tons • Table for minimum number and type of hand portable fire extinguishers based on vessel length and horsepower • Difference between B-I and B-II (or 5-B vs 20-B / 40-B:C) extinguishers and where they are required

💭 Think About

• First, decide which regulatory table applies to a 98 GT towing vessel with 1500 B.H.P.—is it treated like an "uninspected towing vessel" under 100 GT? • Next, think about how many separate spaces normally require extinguishers (accommodation spaces, control spaces, galley, and machinery space). Does the question say the number is including machinery space or only for the machinery space? • Consider how increasing B.H.P. affects the required number/size of extinguishers in the machinery space—does higher horsepower change the count or just the type/size?

✅ Before You Answer

• Verify the correct CFR table that lists hand portable extinguishers for towing vessels <100 GT with specified B.H.P. • Check how many extinguishers are required in machinery spaces versus other spaces, and whether the question wants the total number on board. • Confirm the required size class (B-II / 40-B:C) for the machinery space of a 1500 B.H.P. towing vessel under 100 GT.
