🔍 Key Concepts

• 46 CFR Subchapter I requirements for fire main systems on cargo and miscellaneous vessels • Specific provisions for outlet valves and hydrants on exposed decks • Environmental protection requirements, especially freezing conditions

💭 Think About

• Which of the choices specifically addresses the problem that can occur to fire main outlets on exposed decks in cold climates? • Does 46 CFR require every listed action, or does it focus on a particular type of protection for these deck hydrants? • Think about what is practical and inspectable at each Coast Guard inspection versus what must be built into the system’s design.

✅ Before You Answer

• Look up the exact wording in 46 CFR Subchapter I, in the section covering fire main systems and hydrants. • Confirm whether the regulation mentions glass enclosures, internal examination every inspection, or protection against freezing for exposed deck outlets. • Verify if the regulation groups several requirements together or highlights one specific protection measure for hydrants on exposed decks.
