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.
