What is a Panic Bar?
Panic bars, also known as crash bars, push bars, or exit devices, are a crucial component in modern building safety. These devices allow for quick and efficient evacuation during emergencies. This article delves into the purpose, functionality, and some intriguing aspects of panic bars.
A panic bar is a type of door-opening mechanism found on emergency exit doors. It is a horizontal bar fixed across the width of the door, which, when pushed, unlatches the door allowing for swift exit. This design ensures that in the event of an emergency, such as a fire or other threat, individuals can exit the building quickly and safely.
Why are Panic Bars Used?
- Safety in Emergencies: The primary purpose of panic bars is to ensure a safe and rapid evacuation during emergencies. They allow doors to be opened easily under pressure, preventing bottlenecks and trampling.
- Compliance with Safety Regulations: Many building codes and safety regulations mandate the installation of panic bars on emergency exits to ensure public safety.
- Prevention of Unauthorized Entry: While allowing exit from the inside, panic bars can restrict entry from the outside, adding a layer of security.
Interesting Facts About Panic Bars
- Historical Development: The invention of the panic bar is attributed to Carl Prinzler and Vonnegut in response to the tragic 1903 Iroquois Theatre fire in Chicago, which claimed over 600 lives.
