A fire extinguisher is a portable device used to put out small fires by releasing a substance like water, foam, or gas. It is designed to quickly stop fires before they spread and is commonly found in homes, offices, and public spaces. Fire extinguishers have a nozzle or hose for aiming the substance at the fire and a lever or trigger to release it. They are an important safety tool for emergencies.
