Exit devices are hardware components installed on doors to allow for quick and easy egress in emergencies. They are commonly found in commercial buildings and are designed to be operated with minimal effort, often requiring just a push or a pull to open the door. These devices help ensure that occupants can exit safely and swiftly during situations like fires or other emergencies. Typically, exit devices include features such as panic bars or push bars, which activate the door latch when pressed. They are often used in conjunction with fire safety regulations to meet safety codes and ensure compliance. Proper installation and maintenance of exit devices are crucial for effective emergency evacuation.
