The primary use of a fire extinguisher is to put out small fires or control them until the fire department arrives. Fire extinguishers are equipped with various agents that can suppress flames, including water, foam, dry chemicals, or carbon dioxide, depending on the type of fire they are intended to combat. For instance, specific extinguishers are suitable for electrical fires, while others may be designed for flammable liquids. Proper usage and knowledge of which extinguisher to deploy in different situations are critical for safety during fire emergencies, as a quick response can prevent a small fire from becoming a major disaster.
