A panic bar — an exit device, in the trade — is the horizontal bar across an exit door that unlatches the door when somebody pushes against it. Its whole purpose is that a crowd moving toward a door in a hurry can get through it without anyone knowing how the lock works. That is also why the code cares about it: the question is never whether the bar is nice to have, it is whether people can leave.
Who decides
Georgia's building and fire codes are based on the International Building Code and the International Fire Code with state amendments, and the fire marshal or building official for your jurisdiction applies them to your building. Which doors need panic hardware depends on what the space is used for (its occupancy classification), how many people it is designed to hold, and whether the door is part of the required exit path. Those are questions about your building, not rules an article can settle, so we will not quote an occupant-load number as though it were the law. What we can tell you is what the inspector usually checks, because that part is consistent.
Where panic hardware usually shows up
- Assembly spaces. Restaurants, bars, churches, gyms, event rooms and similar places where a lot of people gather. Above an occupant load the code sets, every door in the exit path that has a lock or latch needs to open with a single push.
- Schools and daycare. Educational occupancies are treated the same way once the room or the building passes the threshold the code sets for them.
- High-hazard spaces. Where hazardous materials are stored or used, panic hardware is expected on the exit doors regardless of how few people work there.
- Electrical and equipment rooms. The electrical code asks for outward-swinging doors with panic hardware on rooms holding large equipment, so the person who caused the fault can get out backward.
- Any door where the owner wants it. Nothing stops a business from fitting an exit device on a door that does not require one, and many do, because it is the hardware least likely to trap anybody.
What the inspector looks for
Once a door has an exit device, the code is specific about how it has to behave, and these are the points that get checked.
- One motion, no knowledge. A push on the bar releases every latch on the door. No key, no thumbturn, no second lock, no chain or slide bolt added later. An extra deadbolt on a panic door is the single most common violation we see.
- The bar spans at least half the door. The push pad has to be wide enough that somebody hitting the door anywhere near the middle unlatches it. A narrow pad set to one side does not qualify.
- Mounted at the right height. The code puts the bar in a band roughly waist high — generally between 34 and 48 inches off the floor. A device fitted where the old hardware happened to be is not always inside it.
- It swings the right way. A door serving enough people to require panic hardware also has to swing in the direction of exit travel. A bar on a door that opens inward does not fix the door.
- Listed hardware. The device carries a listing mark for panic hardware, and on a fire-rated door it is labeled fire exit hardware, which is a different listing: it cannot be dogged open, and the door has to latch by itself every time it closes.
- No dogging on a fire door. Holding the latch retracted on a non-rated door during business hours is fine. On a rated door it defeats the door, and inspectors look for the hex-key holes that show it has been done.
The main-entrance exception
Stores and some other occupancies are often allowed a key-operated lock on the main entrance instead of panic hardware, provided the lock is readily distinguishable as locked, a sign beside the door says it is to remain unlocked when the building is occupied, and the official accepts it. Whether your door qualifies is exactly the kind of thing the fire marshal decides, so ask before you rely on it.
What usually fails
Not the missing bar — a door with no panic hardware where one is required is usually caught at the build-out. The failures we are called to fix are additions and neglect: a deadbolt fitted after a break-in, a chain through the bar overnight that is still there at ten in the morning, a broken spring that no longer retracts the latch, a bent strike, a closer so stiff the door is effectively locked, or a cheap unlisted device bought online that the inspector will not accept.
What to do
If you are building out a space, ask the fire marshal's office which doors need exit devices before the hardware is ordered; the answer costs nothing and it is binding. If you already have panic doors, walk them: push each bar with one hand and watch the door swing clear, look for any lock that is not the bar, and read the label on the device. Anything that fails that walk we can inspect, adjust or replace — same-day when the schedule allows, with a free written estimate on the hardware first.
