Fires are bright, hot flames that occur when materials like wood or paper burn. They can happen naturally, like during a lightning storm, or be started by people, such as when cooking or using a campfire. Fires provide warmth and light, but they can also be dangerous if they spread out of control. When a fire burns, it consumes oxygen and releases smoke and heat. Firefighters, often using special equipment like hoses and fire trucks, work hard to put out fires and keep people safe. Understanding how to prevent fires, such as using smoke detectors and having fire extinguishers, is important for everyone.
