Question 1 of 31093

What is the minimum number of Type B-II hand portable fire extinguishers required to be aboard a 3,000 BHP, 99 GT uninspected harbor tug?

🔍 Key Concepts

• 46 CFR Part 25 – Requirements for fire extinguishing equipment on uninspected vessels • Distinction between Type B-I and Type B-II portable fire extinguishers and their relative capacity • How brake horsepower (BHP) and gross tonnage (GT) affect the required number and type of extinguishers

💭 Think About

• First, determine which specific table in 46 CFR Part 25 applies to an uninspected towing vessel (harbor tug) of 3,000 BHP and 99 GT. What column and row would you be in? • Ask yourself: for machinery spaces on uninspected vessels of this size and horsepower, does the regulation specify only Type B-I, only Type B-II, or a combination? • Once you find the total required fire-extinguishing capacity, convert that requirement into an equivalent number of Type B-II units using the relative capacity values given in the regulation.

✅ Before You Answer

• Confirm in the regulation that you are using the correct vessel category (uninspected towing vessel/harbor tug), not passenger or inspected vessels. • Verify whether the required capacity can be met by multiple Type B-I units OR fewer Type B-II units, and then focus only on the number of Type B-II units that would satisfy the rule. • Double-check that you are reading the correct BHP bracket for 3,000 BHP and not a bracket just below or above it.
