🔍 Key Concepts

• Review 46 CFR requirements for fixed fire-extinguishing systems on uninspected vessels • Know which traditional systems (foam, CO₂, steam) are still considered acceptable under modern regulations • Distinguish between systems commonly used for machinery spaces on small vessels vs older/obsolete systems

💭 Think About

• Ask yourself: Which of these systems can practically and safely be installed in an enclosed machinery space on a small uninspected vessel? • Consider which systems are still commonly found and discussed in current USCG guidance, rather than older, legacy systems. • Think about which option provides effective fire suppression without leaving excessive residue or damaging equipment.

✅ Before You Answer

• Verify which systems are specifically mentioned in 46 CFR Part 25 – Requirements for Lifesaving, Firefighting, and Miscellaneous Equipment for uninspected vessels. • Eliminate any options that are largely obsolete or no longer approved for new installations on small craft. • Confirm that your choice is a fixed system normally used to protect engine rooms or machinery spaces, not just portable firefighting equipment.
