Question 1 of 27070

According to Coast Guard Regulations (46 CFR Part 95.50), how many B-II hand portable fire extinguishers are required in a space containing two 4000 bhp main propulsion diesel engines?

🔍 Key Concepts

• 46 CFR Part 95.50 – especially the table that lists minimum number of B-II extinguishers by total brake horsepower (bhp) of propulsion machinery in one space • How to sum the total bhp when there are multiple engines in the same machinery space • Difference between B-I vs B-II hand portable fire extinguishers and when each size is required

💭 Think About

• First, add up the total brake horsepower for the two main engines in that ONE space. What total bhp do you get? • Next, find the correct bhp range for that total in the 46 CFR 95.50 table and note how many B-II extinguishers it requires. • Finally, check whether the regulation wants the number per engine or per machinery space based on total bhp.

✅ Before You Answer

• Be sure you are using total bhp in the space, not the bhp of just one engine. • Confirm you are reading the correct row and column for B-II hand portable extinguishers in the 46 CFR 95.50 table. • Verify that you are not accidentally mixing requirements for fixed systems or semi-portable extinguishers with the requirement for hand portable B-II units only.
