A panic bar, also known as an exit device, is a device installed on doors that allows for quick and easy exit in emergency situations. It is commonly used in public spaces such as schools, office buildings, and hospitals, ensuring the safety and security of individuals in case of a panic or emergency. So, if you’ve ever seen that horizontal bar on a door, now you know it’s more than just a handle – it’s a panic bar!
What is a Panic Bar?
Definition
A panic bar, also known as a crash bar, push bar, or exit device, is a type of door locking mechanism that is specifically designed for emergency exits. It consists of a horizontal bar that is attached to the inside of a door and spans its entire width. When this bar is pushed, it mechanically unlocks the door, allowing for quick and easy exit in case of an emergency.
Purpose
The primary purpose of a panic bar is to ensure the safety of building occupants in situations requiring rapid evacuation. It provides a reliable and efficient means of exit during emergencies, such as fires, natural disasters, or any other event that necessitates a swift evacuation. Panic bars are particularly crucial in buildings with a high occupancy and are required by building codes and regulations.
Types
Panic bars come in various types to cater to different door configurations and requirements. The most common types include:
-
Rim Panic Bars: These are the most widely used panic bars and are surface-mounted on the inside of doors. They are suitable for single doors or double doors with a mullion.
-
Mortise Panic Bars: These panic bars are recessed into the door edge, providing a sleek and less obtrusive appearance. They are often used in commercial buildings or high-end establishments.
-
Vertical Rod Panic Bars: These panic bars are designed for double doors without a center mullion. They use vertical rods to secure the doors at the top and bottom.
-
Concealed Panic Bars: This type of panic bar is hidden within the door itself, ensuring an aesthetically pleasing appearance while still providing emergency exit functionality.
Installation
Installing panic bars requires careful consideration of the door type, local building codes, and the specific panic bar being used. It is recommended to consult with a professional locksmith or a certified panic bar installer to ensure proper installation and compliance with regulations.
During installation, the panic bar is typically aligned horizontally on the inside surface of the door and securely attached using screws or bolts. The latch or locking mechanism is connected to the panic bar and extends into the door frame, ensuring the door remains securely closed when not in use.
Operation
Operating a panic bar is straightforward and intuitive, making it easy for anyone to use in an emergency. When the horizontal bar is pushed, it activates the internal mechanism, retracting the latch and allowing the door to open freely. Panic bars are designed to require minimal force, ensuring that even children, the elderly, or individuals with limited mobility can easily open the door to escape.
In some models, the inside of the panic bar may also be equipped with a lever or knob to release the latch, providing an alternative method to open the door. However, it is important to note that panic bars should only be used in emergency situations and not as a regular exit.
Building Codes and Regulations
Many countries have specific building codes and regulations in place regarding the installation and use of panic bars. These codes often dictate the types, placements, and specifications of panic bars to ensure they function reliably during emergencies.
For example, in the United States, the Occupational Safety and Health Administration (OSHA) and the National Fire Protection Association (NFPA) have established guidelines that require panic bars to be installed on certain types of exit doors. Compliance with these codes is essential to meet safety standards and avoid potential penalties or legal liabilities.
Maintenance
Regular maintenance of panic bars is vital to ensure their proper functioning in emergencies. It is recommended to establish a maintenance schedule and perform routine inspections of the panic bars in your building.
During inspections, check for any signs of wear, damage, or improper operation. Lubricate moving parts as needed, tighten any loose screws or bolts, and verify that the panic bar is secure and properly aligned with the door.
If any issues or concerns are identified during inspections, it is advisable to contact a professional locksmith or panic bar installer for repairs or adjustments.
