Question 1 of 27070

In order to release CO₂ to the machinery spaces from a fixed fire extinguishing system, you must __________.

🔍 Key Concepts

• Fixed CO₂ fire extinguishing systems sequence of operation • Purpose of the pre-discharge alarm before releasing CO₂ • Difference between a control valve in the machinery space and the main CO₂ releasing valve at the cylinder bank

💭 Think About

• Think about what must happen before people could be exposed to CO₂ in the engine room. What safety step is required first? • Which valve actually allows CO₂ to flow from the cylinders into the engine room piping, and which valve only prepares or directs the flow? • Consider whether simply operating valves is enough, or whether a warning to personnel is required by safety practice and regulations.

✅ Before You Answer

• Verify which component activates the local alarm for personnel in the machinery space. • Identify which valve is located near the cylinder bank and which is located outside the protected space as a control station. • Confirm that the correct sequence includes a warning/alarm step before the gas is actually discharged.
