The fire department is a group of brave people who help prevent fires and put them out if they happen. They have big trucks that can carry water and tools to help save people and homes. The fire department is like a superhero team that always stands ready to help when there is a fire or an emergency. They wear special clothes and helmets that protect them from the heat and flames of a fire. They also teach people how to be safe and prevent fires from happening in the first place. It's important to always listen to the fire department and follow their instructions to stay safe.
