When Can a Fire Door Be Propped Open?

Lastly, section 8.3. 3.1 states that any door required to have a fire protection rating must comply with NFPA 80, which requires self-closing devices on the doors. So, any fire-rated door is not permitted to be wedged or propped open.

When should fire doors be wedged open?

Fire doors should be closed at all times, unless certified fire door retainers have been fitted. Fire door retainers hold fire doors open until a fire alarm is set off, closing it once the alarm has been triggered.

Is it okay to prop open a fire door?

Don't prop open the door with wedges or by bending the closing mechanism. Aside from possibly rendering the fire door inoperable due to physical damage, propping open fire doors will allow products of combustion to migrate into other areas and contribute to the spread and severity of the fire.
