🔍 Key Concepts

• CO2 fixed fire-fighting systems and how they extinguish fires (oxygen displacement and cooling) • Importance of a sealed / closed compartment for gas-based extinguishing agents • Effect of ventilation and airflow on gas concentration in a protected space

💭 Think About

• What does CO2 need to do inside the space to put the fire out, and what happens if fresh air can easily enter? • How would opening doors, hatches, or ventilators affect the concentration of CO2 around the fire? • Which option best maintains a high concentration of CO2 around the fire for long enough to cool and smother it?

✅ Before You Answer

• Identify which choices increase air supply or ventilation to the compartment and which reduce it • Ask: In which situation will CO2 stay inside the compartment instead of leaking out? • Confirm that the chosen option allows CO2 to reach and maintain its effective concentration without being diluted by outside air
