Fire alerts are warnings that alert people to the presence of a fire. They can come in the form of SIRENS, which are loud, high-pitched noises that can be heard from a distance. SIRENS are often used by fire departments to alert people to evacuate an area or to take other safety measures. Fire alerts can also come in the form of visual signals, such as flashing lights or smoke signals. Fire alerts are important for keeping people safe and helping to prevent the spread of fires.
