Which of the following is a characteristic of carbon dioxide extinguishers?

Effective on Class A fires
Creates a foam effect on fires
Disperses quickly and cools surrounding air
Leaves a residue after use

The correct answer is: Disperses quickly and cools surrounding air

The characteristic of carbon dioxide extinguishers is that they disperse quickly and cool the surrounding air. When carbon dioxide is released from the extinguisher, it rapidly expands and produces a cooling effect due to its low temperature. This process helps to displace oxygen around the fire, effectively suffocating it and interrupting the fire's chemical reaction. In contrast, other types of extinguishers may serve different purposes or reactions. For example, carbon dioxide extinguishers are not effective on Class A fires, which typically involve materials like wood, paper, or textiles; they are primarily designed for Class B (flammable liquids) and Class C (electrical) fires instead. Additionally, unlike foam extinguishers, carbon dioxide does not create a foam effect on fires. Lastly, carbon dioxide leaves no residue after use, making it ideal for applications where cleanliness is paramount, such as in laboratories or data centers.
