🔍 Key Concepts

• 46 CFR requirements for fire main systems and hoses on offshore supply vessels (check Part 108 or Part 27 depending on vessel type and size) • Details about hose markings and storage in machinery spaces (engine rooms) • Specifications for fire hose couplings and thread standards on U.S. vessels

💭 Think About

• Look at each choice and ask: is this an explicit regulatory requirement, or does it sound like a convenient practice that might NOT actually be required? • Consider whether a fire hose being removed in heavy weather would increase or reduce safety and readiness for immediate use. • For the coupling threads, think about whether the regulation would specify exact thread counts for standard sizes, and why that might be important on a fleet of vessels and shore connections.

✅ Before You Answer

• Verify in 46 CFR whether fire hoses are required to be permanently attached and ready for use at engine room hydrants. • Check if there is a specific CFR citation that requires the vessel’s name to be marked on the fire hose itself (not just on equipment generally). • Confirm whether the CFR actually lists thread-per-inch specifications for 1 1/2" and 2 1/2" hose couplings, and if so, whether they match the values in choice B.
