🔍 Key Concepts

• Look closely at the fixed firefighting symbols shown in the Auxiliary Machinery Flat on SF-0044 (especially the gas discharge symbols and sprinkler/drenching symbols). • Think about which systems are normally used for machinery spaces with fuel and oil present versus accommodation or storage spaces. • Consider the difference between a local application water/drenching system and a total-flooding gas system in an enclosed machinery flat.

💭 Think About

• On the plan, what type of fixed system piping or discharge heads are actually drawn inside the Auxiliary Machinery Flat? Compare their symbols to those in the main machinery space just below. • For a fire that is already "out of control" in an enclosed machinery flat, which type of fixed system is designed to quickly smother the entire volume of the space rather than just cool or wet surfaces? • Which of the listed agents (water, drenching, CO2, Halon) is most appropriate for flammable liquids and energized machinery in a confined space, and which ones are more suited to accommodation or deck areas?

✅ Before You Answer

• Verify the legend/symbol on the drawing that identifies CO2 discharge heads or lines in the Auxiliary Machinery Flat. • Confirm whether there is any drenching or sprinkler symbol actually installed in that specific flat, or if those appear only in other areas. • Make sure your choice matches both: (1) the system actually shown in that space on SF-0044 and (2) the suitability for machinery-space fuel/oil fires.
