An emergency exit is a designated route or door that allows people to leave a building quickly and safely during an emergency, such as a fire or earthquake. These exits are usually marked with bright signs and are often located away from the main entrances to provide a clear path to safety. Emergency exits are equipped with features like panic bars or push doors, which enable easy access without needing a key. Regular maintenance and clear pathways to these exits are essential to ensure they function properly when needed, helping to protect lives in critical situations.
