A Panic Bar, also known as a crash bar or exit device, is a safety mechanism installed on doors to provide a quick and easy way to exit a building during emergencies. It typically consists of a horizontal bar that, when pushed, unlatches the door, allowing it to open outward. This design is especially useful in crowded places, ensuring that people can evacuate swiftly without fumbling for a doorknob. Panic bars are commonly found in public buildings such as schools, hospitals, and theaters, where large groups of people may need to exit quickly. They are often required by building codes and safety regulations to enhance emergency preparedness. The installation of a panic bar can significantly improve safety during fire drills or other urgent situations.
