Question 1 of 31048

How many B-II or post 2017 40-B:C fire extinguishers must be in the machinery space of a 75-foot-long fishing vessel propelled by engines with 1200 brake horsepower?

🔍 Key Concepts

• 46 CFR Subchapter C or T fire extinguisher tables for machinery spaces on fishing vessels • How vessel length and total brake horsepower (BHP) affect the number and size (B-II or 40-B:C) of required extinguishers • Difference between portable extinguishers and any required fixed fire-extinguishing system in the machinery space

💭 Think About

• First, decide which regulation table applies to a 75-foot fishing vessel with 1200 BHP. Is it treated as an "under 90 feet" vessel, and does horsepower cross any threshold in the table? • Check whether the table calls for a minimum number of B-II (or 40-B:C) extinguishers in machinery spaces, and whether an additional extinguisher is required when horsepower exceeds a certain value. • Consider whether the presence (or absence) of a fixed fire system in the machinery space would change the number of required portable extinguishers.

✅ Before You Answer

• Verify in the correct CFR table how many B-II (or post-2017 40-B:C) extinguishers are required for a vessel over 65 ft but under 90 ft in length in the machinery space. • Check if 1200 BHP crosses any listed horsepower breakpoint that increases the required number of extinguishers. • Confirm that you are counting only the machinery space requirement, not total extinguishers for the entire vessel.
