Question 1 of 27070

Your vessel must have a B-II fire extinguisher. Which extinguisher fulfills this requirement? (small passenger vessel regulations)

🔍 Key Concepts

• USCG fire extinguisher classifications for small passenger vessels (e.g., B-I vs B-II) • Minimum agent weight/capacity required for a B-II extinguisher, especially for CO₂ vs dry chemical vs foam • Tables in 46 CFR Subchapter T that list acceptable extinguisher sizes and types

💭 Think About

• First, decide which of the choices are even Type B extinguishers suitable for flammable liquids (fuel, oil) likely to be on a small passenger vessel. • Then compare the size/capacity of each option to what is required for a B-II rating—ask yourself which one is large enough to qualify as B-II rather than B-I. • Think about how CO₂, dry chemical, and foam are rated differently—does a small weight of CO₂ or dry chemical usually correspond to a higher or lower rating?

✅ Before You Answer

• Verify in 46 CFR Subchapter T (small passenger vessels) which extinguisher sizes (in pounds or gallons) correspond to B-II rating. • Check which listed options are clearly too small and would more likely match a B-I rating based on their size. • Confirm that the extinguisher you choose is a portable, USCG-approved Type B-II unit, not just any fire extinguisher.
