【 Importance of keeping fire/smoke doors closed 】

    Smoke and fire doors usually refer to the doors located in the stairway, elevator, cable well, flue, etc., used to maintain the fire integrity and heat insulation of the fire escape channel, and provide an escape route. The fire door is usually closed, and it needs to be opened when there are people walking around. Because the place where the fire door is installed is usually the channel where the personnel often walk, especially the large flow of personnel such as large shopping malls and commercial residential buildings, if the evacuation stairwell is set up in its internal closed fire door, it can effectively delay the fire and smoke to the stairwell and the fire passage in the event of a fire, and win precious time for the evacuation of personnel. Therefore, it is necessary to keep the normally closed fire door in the normally closed state, and it must not be convenient to open the door or lock the fire door in order to prevent theft. In order to strengthen the public's safety awareness that normally closed fire doors should always be closed, the word "should always be closed" must be used on fire doors.

    Conventional fire doors are divided into the following types:

a) Fireproof glass door

    It is composed of stainless steel profiles, fireproof glass and fireproof hardware accessories, with good lighting and strong permeability. When there is a fire, the glass door can see the opposite situation clearly and reduce the occurrence of accidents.

b) Fireproof wooden doors

    Use refractory wood or refractory wood products as the door frame, door frame, door panel, if the door filler material, then fill the human body non-toxic and harmless fire insulation material, and with fireproof hardware accessories composed of a certain fire performance of the door.

  c) Fireproof steel door

    Because crowded places need to set fire doors in the escape channel, the interior of the steel fire door is filled with a fireproof material with certain fire resistance, which can be used to block the spread of fire when the fire occurs, and plays an indispensable role in the fire fighting work. The fire (smoke) door must be kept closed regularly to avoid losing the barrier function!
