🔍 Key Concepts

• Properties of carbon dioxide (CO₂) as a fixed fire extinguishing medium on ships • Difference between cooling vs smothering (oxygen displacement) as extinguishing methods • Which fire classes (A, B, C, D, K) are typically suited for CO₂ systems

💭 Think About

• Ask yourself: Does CO₂ work mainly by cooling the fire or by taking away oxygen? Which option best reflects that? • For a large machinery-space fire, would you want the CO₂ discharged slowly over time, or rapidly to quickly change the atmosphere in the space? • Consider whether CO₂ is known to be chemically corrosive to equipment, or relatively clean and residue-free.

✅ Before You Answer

• Identify which choice describes smothering vs cooling more accurately for CO₂. • Recall which fire class deals with flammable liquids and whether CO₂ is commonly used for that class. • Eliminate any option that contradicts the basic, well-known property that CO₂ systems leave no corrosive residue on machinery and equipment.
