Understanding Emergency Exit Hardware
Emergency exit hardware is designed to allow safe and rapid egress from a building during emergencies. These devices are typically installed on exit doors in commercial buildings, schools, warehouses, and public facilities.
Exit hardware ensures people can open the door by pushing a bar—without the need to twist knobs or fumble with locks. In emergencies, especially where crowd panic is likely, this design saves lives.
Two common types are panic bars and crash bars. Though they serve similar functions, the differences lie in construction, compliance, and use-case scenarios.
What Is a Panic Bar?
A panic bar is a spring-loaded metal bar that spans horizontally across the inside of an exit door. It unlatches the door when pushed and is specifically designed for emergency egress.
Panic bars are required on doors in buildings that accommodate large numbers of people, including schools, churches, and retail spaces. They're also mandated by the International Building Code (IBC) in many situations.
These devices must meet ANSI and UL standards to qualify as panic hardware. Want to learn more? See our article on choosing fire-rated panic bars.
What Is a Crash Bar?
“Crash bar” is a more general term, often used colloquially to describe any push bar on a door. Some crash bars are certified panic devices, but not all of them are.
Crash bars might be used on non-egress doors, warehouse roll-up doorways, or service exits where code does not specifically require panic hardware. They may look similar but lack the same safety certifications.
When people refer to crash bars, they could be talking about older models or less-regulated push bars that do not meet panic hardware standards.
Panic Bar vs. Crash Bar: Key Differences
The terms are often used interchangeably, but there are critical distinctions between panic bars and crash bars. Here’s a breakdown:
- Certification: Panic bars are tested and certified to meet life safety codes. Crash bars may not be.
- Usage: Panic bars are required on designated emergency exits in high-occupancy buildings. Crash bars can be used on secondary or low-traffic doors.
- Code Compliance: Panic bars meet ANSI A156.3 and UL 305 standards. Crash bars may not meet any code requirements.
- Build Quality: Panic bars are built with stronger materials and safety features. Crash bars may have looser tolerances and lower-grade construction.

Code Compliance: When Each Is Required
Fire codes and building regulations often dictate the use of panic hardware. Panic bars are required on exit doors serving rooms with 50 or more occupants in most commercial buildings.
Crash bars, unless they meet the same standards, are not considered compliant for those exits. Installing the wrong type can lead to failed inspections and safety violations.
If your door also needs to be fire-rated, be sure the panic bar includes UL labeling. Learn more from our guide on selecting compliant fire-rated hardware.
Safety and Security Considerations
Panic bars provide fast, one-motion egress, which is critical in emergencies. They’re designed to work under pressure—even if someone is pushing at the wrong angle.
They also secure the door from the outside, acting as a lock when paired with alarm systems or electric strikes.
Crash bars may not always engage or re-latch properly, especially if they’re older or low-grade. That poses risks in both fire scenarios and break-ins.
For added security, consider pairing your panic bar with a proper door closer. See our article on how to pick the right door closer.
Installation and Maintenance Tips
Installing panic hardware requires precision. Misalignment can prevent the latch from engaging, rendering your emergency exit useless.
We recommend hiring a licensed locksmith familiar with code requirements. Panic Bar King Katy provides professional installation, adjustment, and testing to ensure smooth function.
If your panic bar isn’t latching, don’t ignore it—check out our guide on adjusting a panic bar that won’t latch.
Routine maintenance includes checking tension, lubricating moving parts, and testing for alignment and door closer function.
Which One Should You Choose?
If your building is open to the public or holds more than 50 people, go with a certified panic bar. It meets code, reduces liability, and keeps people safe.
Crash bars may be suitable for storage areas or doors not designated as emergency exits. They’re cheaper, but they lack safety certifications.
If you’re unsure which one is appropriate for your door, our team can inspect your setup and provide a recommendation.

Common Myths About Panic and Crash Bars
- “They’re the same thing.” – False. Only panic bars are tested and approved for emergency egress.
- “Any push bar is code compliant.” – Wrong. Only certified models meet code.
- “They’re only needed in large buildings.” – Not true. Any public-use building may require them depending on occupancy.
- “They’re too expensive.” – Not when you consider the cost of fines or liability after an incident.
