Fire rated doors serve a purpose. They are manufactured in a way that is to help reduce the spread of fire and smoke. Fire rated doors allow occupants time to safely exit the structure during a fire or to allow for an area of refuge within the building that protects them until fire service can arrive. These fire rated doors are also part of the building's design and serve to protect fire service personnel during fire suppression. When the door is not properly latched in its frame it loses its effectiveness. When they are not properly maintained they are of no value during a fire making the design and purpose of the door obsolete.
Fire Rated Metal Door
Fire Rated Wooden Door
Fire doors are composed of a combination of materials, including steel, gypsum and other fire resistant materials. Some have fire rated windows, which must be listed for use. These windows may include wire mesh glass, liquid sodium silicate between to window panes, ceramic glass or borosilicate glass. Fire doors are needed when a door has an "exit" sign near or on it, when a door leads to stairwells and horizontal exits, or when a door heads to a hazardous area such as a room used to store flammable liquids. All fire rated doors and frames must be equipped with labels indicating they have met all testing requirements. The label must be provided by a certified testing agency, such as Underwriters Laboratory. It may be embossed or mechanically fastened to the door itself. Labels must indicate the door's fire rated duration such as 90 minutes and may not be painted over or tampered with in any way.
The labels will typically be located on the door near the fire rated door hardware or on the door frame.
