Why fire doors matter
Fire doors are part of the building’s passive fire-protection strategy. When they are in the correct position and operating as intended, they help protect openings in fire-rated assemblies and can limit the movement of smoke and fire. In apartment buildings, doors protecting stairs, corridors, service rooms and other fire separations can be especially important.
A door only provides its intended protection when the complete assembly can function. The door leaf, frame, closer, hinges, latch, glazing, seals and other hardware may all matter depending on the assembly.
What building staff can look for
- Doors wedged, tied or otherwise held open without an approved automatic arrangement.
- A door that does not close fully from the open position.
- A door that reaches the frame but does not latch when it is intended to latch.
- Damaged, loose or missing hardware.
- Holes, severe damage or field modifications to the door or frame.
- Objects, mats or storage that interfere with closing.
- Automatic closers that are disconnected, leaking, damaged or adjusted so the door cannot function properly.
- Magnetic hold-open devices that do not release as intended during an approved test.
Why some fire doors are normally open
Some fire doors are equipped with approved hold-open devices connected to the building’s fire alarm or detection system. In normal conditions the door may remain open for convenience or accessibility; when the releasing condition occurs, the device lets the door close.
That is very different from a wedge, hook, chair or other improvised method of holding a fire door open. Building staff should know which doors are designed to be held open and should report a device that does not release or a door that does not close properly.
The handbook connects fire doors and fire separations with exits, alarms, sprinklers, inspections, records, impairments and day-to-day building operations.

Do not treat exit stairs as storage areas, and do not prop stair or corridor doors open. U.S. Fire Administration guidance specifically warns against propping open exit or stairway doors because they are installed to slow the spread of heat and smoke.
Repairs and alterations
Do not drill, cut, paint over labels, add hardware or make field modifications to a fire door simply because the change seems minor. Repairs and alterations can affect the performance or listing of the assembly. Use qualified service personnel who understand the door type and applicable requirements.
Document deficiencies and corrective action
When staff notice a problem, record the location, door identifier if one exists, observed condition and date. Arrange the appropriate assessment or repair, then document completion. Repeated problems—such as the same door being propped open—may also point to an operational issue that needs training or a building-use solution.
