What would be the most probable cause for a high-pressure alarm to be activated in a low-pressure CO2 fixed fire extinguishing system?

🔍 Key Concepts

• Behavior of CO2 pressure in response to temperature changes • How a low-pressure CO2 storage tank is kept at its normal operating pressure (chillers/cooling system) • Difference between loss of CO2 vs. rise in CO2 pressure

💭 Think About

• Which option would cause the pressure inside the CO2 tank to increase, not decrease? • How would a failure of the cooling or refrigeration system affect the CO2 pressure in the tank? • Do leaks (of CO2 or air) normally make system pressure go up or go down?

✅ Before You Answer

• Identify which choices would more likely cause low pressure instead of high pressure. • Think about the relationship: higher temperature → higher pressure in a closed tank of liquefied gas. • Recall the purpose of the tank cooling system in a low‑pressure CO2 installation and what happens when it fails.

The pilot cylinder discharge valve is leaking.

The tank cooling system has malfunctioned.

An excessive amount of insulation has been installed on the tank and piping.

An air leak has developed in the tank.
