🔍 Key Concepts

• 46 CFR requirements for fire pumps and piping on tankships • Purpose of a pressure gauge in a fire main system • Location in the system where pressure is most usefully monitored during firefighting

💭 Think About

• Think about where the pressure needs to be known to confirm the fire pump is performing properly for the whole system, not just one outlet • Consider which location will reflect the pump’s actual output to the fire main, regardless of which stations are in use • Ask yourself which option would give the operator a reliable reading whenever the pump is running, without depending on a specific hose or station being in use

✅ Before You Answer

• Verify which point in the system represents the pump’s output to the fire main, not a specific user point • Check that the gauge location would allow monitoring even if no fire stations are actively discharging water • Confirm that the selected point gives a consistent, system-wide indication of pump performance, not just local pressure at one station
