CO2

CO2: When released in sufficient quantities, carbon dioxide displaces oxygen from the surrounding area, effectively smothering the fire by removing its essential element for combustion. This makes CO2 an effective extinguishing agent for certain types of fires, especially those involving flammable liquids or electrical equipment. However, it's important to note that using CO2 for fire suppression can be dangerous in confined spaces as it may displace breathable air and pose a risk to human health.
