Understanding Emergency Exit Hardware
Emergency exit devices are designed to allow fast and safe egress during emergencies. These include hardware like push bars, rim devices, vertical rods, and alarm-equipped exits. Their purpose is to simplify exiting without keys, twisting knobs, or special knowledge.
In Friendswood, most commercial buildings must follow local building codes based on the International Building Code (IBC) and NFPA guidelines. The right exit hardware keeps your facility compliant and helps protect lives in an emergency. If you're not sure where to begin, see our guide on why exit hardware is a must-have for commercial properties.
What Is a Panic Bar?
A panic bar is a spring-loaded metal bar installed horizontally across the inside of a door. When pressed, it unlatches the door instantly—allowing anyone to exit quickly in an emergency. Panic bars are specifically designed for spaces that host the public or large groups of people.
They are required on many fire exits and emergency exits in Friendswood and must meet UL and ANSI standards. Most panic bars are fire-rated and paired with automatic door closers to ensure the door latches after each use.
What Is a Crash Bar?
Crash bars are very similar to panic bars in design and appearance. The term "crash bar" is often used informally and may refer to any push-bar style exit device. In practice, however, crash bars are usually installed in buildings where emergency egress is not legally required.
While they function the same way, crash bars may not be fire-rated or code-compliant, especially for occupancy-sensitive areas. They are popular in gyms, storage facilities, and employee-only exits where convenience is a higher priority than code enforcement.
Panic Bar vs. Crash Bar: Key Differences
The biggest difference lies in legal classification. Panic bars must meet UL305 and ANSI/BHMA A156.3 standards, while crash bars may not. Panic bars are required by law in specific occupancies like schools, churches, and theaters.
Crash bars, on the other hand, can be generic push bars without certification. They often lack fire rating and may include features like mechanical dogging (which keeps the door unlatched) that panic bars are prohibited from having.
For fire exits, a panic bar must be installed in tandem with fire-rated doors and door closers. Learn more in our post on selecting fire-rated panic hardware for code-compliant installations.
Code Compliance: When Each Is Required
Panic bars are required by code on egress doors serving assembly areas with an occupant load of 50 or more. This includes classrooms, restaurants, retail spaces, and gyms in Friendswood.
Crash bars may be used on employee exits or secondary doors without public access, but should not be substituted on fire exits or doors with code-mandated egress hardware.
Safety and Security Considerations
Panic bars offer superior reliability and safety under pressure. They’re tested for impact, heat, and accessibility compliance. When connected to exit alarms, they also help secure emergency-only doors against unauthorized use.
Crash bars can still be effective, but lack fire protection and long-term durability, making them best for low-risk doors where code compliance is not a factor.
Installation and Maintenance Tips
Proper installation is crucial for both types of hardware. Mounting height, bar length, and door material all affect performance. Fire-rated panic bars should always be paired with compatible components to maintain UL compliance.
If your bar doesn’t latch properly, see our guide on adjusting panic bars that don’t latch. Regular inspection and lubrication help extend the life of both panic and crash bars.
Which One Should You Choose?
Choose a panic bar if your door serves the public or is required by code to function as a fire exit. Choose a crash bar only if the door is for staff-only use and code compliance isn’t required.
If you're unsure, consult our team or check your local occupancy classification. You can also browse our guide on where to source commercial hardware in Friendswood TX to explore certified options.
