Fire Door Failure
Fire doors are sometimes rendered unable to provide its listed fire resistance by ignorance of the intended use and associated restrictions and requirements, or by improper use. For example, fire doors are sometimes blocked open, or carpets are run through them, which would allow the fire to travel past the fire barrier in which the door is placed. The door's certification markings are displayed both on the door leaves and the fire door frames, and should not be removed or painted over during the life of the building.
Sometimes fire doors have apparently very large gaps at the foot of them, an inch or two even, allowing air movement, such as in dormitory facilities. This can lead the occupants of a building to question their status as 'real' fire doors. Testing of fire doors include a maximum door undercut of 3/4 inch. Corridors have a fire rating of one hour or less, and the fire doors in them are required by code to have a fire rating of 1/2 or 1/3 hr, the intent of which is mainly to restrict smoke travel.

“Not till the fire is dying in the grate,
Look we for any kinship with the stars.
Oh, wisdom never comes when it is gold,
And the great price we paid for it full worth:
We have it only when we are half earth.
Little avails that coinage to the old!”

But were stopped by the door of a tomb—
By the door of a legended tomb;
And I said—” What is written, sweet sister,
On the door of this legended tomb?”
She replied—”Ulalume—Ulalume!—
‘Tis the vault of thy lost Ulalume!””
—Edgar Allan Poe (1809–1849)
