Are you curious to know about the Panic bars and their testing? If yes, you are at the right place. Generally, panic bars are emergency/Panic exit devices or crash bars. These are quick door-opening mechanisms used for emergency exits. After installation, Panic Bars Testing is mandatory to check its safe and reliable functionality.
The panic bars are installed in the form of horizontal bars or push pads. Also, inspection and testing are done by the OSHA inspectors in the USA. Further, to broaden your knowledge about the setting of Panic bars, their testing, and more, read this brief post.
How to install the Panic Bars?
The panic bars installation procedure requires measuring and marking the installation points on the door. It ensures ease of accessibility for the average height, which fits everyone. This process must comply with applicable USA standards for safe usage during emergencies.
The panic bars are mandatory for doors in public buildings, educational facilities, hospitals, and entertainment venues. Now, take a look at the quick steps for installing the crash bars:
Choose the right type of Panic bar
The Panic bars are available in traditional and modern styles. These differ in features and ease of accessibility. The main exit bars are:
- Surface vertical rod panic bars
- Concealed vertical rod panic bars
- Side latch panic bar levers
- Rim Panic Bars
- Mortise panic bars
It is crucial to choose a suitable Panic bar first. Then opt for Electronic, Fire-rated, or Alarmed styles in your selected crash bars.
Examine the door and mark it
While getting ready with your toolkit and Panic bar, examine the exit door. Remember, you can fix the Panic bars on the wooden or metal doors. So, verify the door frame first and select a suitable panic bar before you begin the panic bars installation procedure.
Afterward, measure and mark the installation points as per the US government and local area standards, where the accurate mounting height is 34-48 inches above the floor. Also, confirm that the bar is installed on the egress side of the door and that it complies with local building codes and fire safety regulations.
Drill holes and mount the panic bar
Drill the holes at the points you marked recently using the accurate sizes of anchors and screws. Now, install the panic bar using the provided screws and anchors. Fasten them properly for smooth operation.
Install the strike plates (latch-based Panic bars)
If you are using latch-based Panic bars, such as Rim or side latch exit bars, then strike plate installation is mandatory. The strike plate ensures that the latch is engaged properly and functions smoothly. Hence, attach the strike plate to the door frame, ensuring it is properly aligned for smooth operation.
Here, you are all set with the panic bars installation. Now, test the panic bars to check their functionality.
How to conduct Panic Bars Testing?
The key role of testing a panic bar is to ensure its safety and smooth operation. This includes verifying the mechanism of the Panic bar to open it with minimal force. The test often involves applying force to the bar while a door is loaded, simulating an emergency scenario. This ensures the door can be opened with a maximum force of 220N.
Multiple tests are performed to ensure the smooth and secure function of the Panic bars. If you want to understand the procedure of testing a panic bar, then walk through these key points:
- The panic bar is first tested for its durability. The exit bar is placed in a test fixture, simulating a door, and operates at a maximum rate of 15 cycles per minute.
- The Emergency operation test is conducted before and after the endurance examination.
- It ensures that a force of 66N or less can unlatch the door. The device must operate when pressure is applied to the push pad or crossbar.
- Afterward, an Ambient exposure test is conducted by exposing the device to high temperatures. It assures that the product can withstand high temperatures.
- The low temperature test is also performed to check the device’s ability to operate well if subjected to low temperatures.
- The preloading test is done for Grade 1 panic devices. It simulates the actual loads on the device before starting the cycle test.
OSHA Regulations and Code Compliance for Panic Bars Installation and Testing
OSHA generally stands for the Occupational Safety and Health Administration. This sets a few of the regulations that need to be followed. The key mission of this US federal agency within the Labor Department is to ensure safe and healthy working conditions. So, to install, test, and use the crash bars, one must follow the OSHA regulations:
- Exit doors must be unlocked, and employees must be permitted to open them from the inside at all times without keys, tools, or special knowledge.
- Devices such as panic bars that lock only from the outside are allowed on exit egresses.
- Exit route doors must be free of any device or alarm that could restrict emergency use if the alarm or other gadgets fail.
- Remember that non-compliance with these regulations can result in significant fines, legal liabilities, or even closure of the premises.
The codes one must know for the Panic bar fixing
International Building Code (IBC) and International Fire Code (IFC)
- Assembly (Group A) and Educational (Group E): Occupancies with an occupant load of 50 or more persons.
- High Hazard (Group H): occupancies, regardless of occupant load.
NFPA 101: Life Safety Code
- Assembly, Educational, and Daycare: occupancies with an occupant load of 100 or more persons.
- High Hazard occupancies with an occupant load exceeding 5 persons.
Wrapping up
Panic bars play a crucial role in emergency preparation, offering a quick and safe way to exit buildings during critical situations. The crash bars are installed as per OSHA rules and building codes.
This ensures these life-saving devices function reliably when needed most. By adhering to regulatory standards and conducting Panic Bars Testing, property owners can remain compliant, protect lives, and promote safer environments across public and private spaces.
