Question 1 of 31048

What is the minimum number of 20-B hand portable fire extinguishers required on board a 105 GT uninspected towboat built in 2017 with a 7500 B.H.P. plant (including the machinery space)?

🔍 Key Concepts

• 46 CFR Part 25, Subpart 25.30 – Firefighting equipment on uninspected vessels • Difference between hand-portable and semi-portable fire extinguishers and whether they BOTH count toward the total • How vessel length and propulsion horsepower affect the number of required extinguishers on uninspected towing vessels

💭 Think About

• First, identify the correct CFR table for fire extinguishers on uninspected motor vessels and confirm it applies to towing vessels of 105 GT built after 2010. • Ask yourself: does the machinery space requirement add extra extinguishers beyond the basic number for the vessel’s size, or is it already included in the base number? • Consider how a very high brake horsepower (B.H.P.) plant (7500 BHP) might trigger additional requirements for fire extinguishing equipment compared with low‑power vessels.

✅ Before You Answer

• Verify in 46 CFR 25.30-20 and 25.30-80 which category this towboat falls into and which table row applies. • Confirm how many 20-B or larger hand-portable extinguishers are required for a vessel of this length and type, before adding for machinery spaces. • Double-check whether any required semi-portable (fixed-location) extinguishers are separate from the hand-portable count the question is asking about.
