How Fire Door Maintenance Ensures Real Safety

Fires are considered to be natural or they can also be man-made. In forests, they are required for natural re-growth of plant species and these fires are started through lightning or by the heat of the sun. Without fire, man is not able to do a lot of things like cook food, heat metal and many others. However, when fire occurs in structures and buildings, it is considered a detriment because this fire can also claim lives and damage expensive property.

There are minimum standards for the components of a fire rated door. A fire door maintenance inspector can make sure that all components are verified. There are two kinds of hardware used for doors and to classify them according to type will ensure that the fire door will function as indicated.

Here are the some tips on what door inspectors are going to check:

The surface of the door and frame – There should be no open holes or breaks on the surfaces because this will make the door less fire-proof. Fire needs only a small crack to be able to penetrate the core of the door, which will make it useless as a protective door. Take note that fire doors are just coated with a special material so that fire won’t be able to burn it for a while. After the indicated threshold, the door will also succumb to the heat and will disintegrate.

Intact vision light frames, glazing and glazing beads – They should all be in place and accurately fastened. These are inspected, in case the door has the above mentioned parts. glass fire doors

Secure and aligned frame, door and hinges – Other components are non-combustible as well and are functioning without apparent signs of breakage or damage. Fire rated door sets must be properly fitting to avoid the escape of fire from one area to another.

Measurement of door clearance – Should the inspector find out that the clearance is above ¾ of an inch, they will request for repair of the clearance until distance under the door bottom does not exceed the said measure. Improper clearance, which can be more than what is prescribed will ruin the capacity of the fire door since the seal may not be able to cover all the gaps when subjected to fire.

No missing parts – The inspector will be able to identify which parts are missing during the inspection. This is to make sure that no gaps or holes will be present on the door because this is practically a great hazard. Should there be missing parts, there will be a request for replacement of these parts.

Functioning self-closing device – The active door should be able to close from a fully open position. Fire doors must be self-closing because the protection from fire should be automatic, even when there is no one around the place when a fire has started. As the heat intensifies, the intumescent seal expands, limiting the extent of fire to a certain area.
