I was curious how a Fire door is defined?
From the 2018 NFPA Glossary of Terms:
Fire Door: The door component of a fire door assembly.
Fire Door Assembly: Any combination of a fire door, a frame, hardware, and other accessories that together provide a specific degree of fire protection to the opening.
Why the question??? May help also with the answer
OHHH I am not an engineer, so you can discount my reply if you want, and I cannot do math.
I will be adding all interior fire doors to our PM system. My safety guy is under the impression that if it has a closer its a fire door. I'm assuming short of checking each label there is no hard rule?
In terms of the building and life safety codes, Fire Door Assemblies are not required in non-fire resistant rated barriers. Door labels and closing hardware are not a determinate factor in identifying fire door assemblies, fire resistant barriers are the determining factor. You may need to consult the original construction plans to identify the fire resistant barriers.
