Fires require fuel, oxygen, and heat. Fuel sources include trees, bushes, wood, furniture, books, and paper. Oxygen is abundant in the air. Fires can start from natural disasters like earthquakes or volcanoes, or from human causes such as negligence, drought, or lightning. Proper fire prevention includes disposing of ashes safely, having smoke detectors and fire extinguishers, creating a fire escape plan, and being careful with any potential fire sources. Fire damage results in loss of lives and property, financial costs, and environmental impacts. It is important to take even small fire risks seriously and know how to use extinguishers to prevent larger disasters.
