In what application is a remote valve operator most likely to be located outside the machinery space when the valve itself is located within the machinery space?
• Fire safety and explosion risk in different piping systems (fuel, compressed air, potable water, seawater) • Location and purpose of remote shutdowns/remote-operated valves on ships • Regulatory focus on controlling flammable liquids from a safe location outside machinery spaces
• Which of these systems would be the most dangerous if a pipe were to rupture and catch fire inside the machinery space? • On which type of line would you most expect the regulations or company procedures to require emergency remote closure from outside the space? • Think about past casualty reports: which fluid is most often associated with machinery space fires and requires rapid isolation?
• Identify which medium is flammable versus non‑flammable • Consider which line, if it fails, could feed or spread a machinery space fire the fastest • Recall that remote valves located outside the machinery space are often intended for emergency shutdown during a fire
