🔍 Key Concepts

• Fixed CO2 fire-extinguishing systems for machinery spaces • Why ventilation is critical when CO2 is discharged • What equipment must stop to contain the CO2 and prevent feeding the fire

💭 Think About

• When CO2 is released into an enclosed space, what has to happen to the airflow so the gas can reach and stay at the proper concentration? • If fans or blowers keep running, what will they do to the CO2 and the smoke in the space? • Think about which type(s) of ventilation would remove or dilute the CO2 from the protected space.

✅ Before You Answer

• Identify all types of ventilation that can move air in and out of the space • Consider whether both supply and exhaust affect the CO2 concentration • Verify that the shutdown scheme is designed to keep CO2 inside the protected space, not let it escape.
