NFPA 80 – Standard for Fire Doors and Other Opening Protectives is the standard that includes detailed information about fire door assemblies. This standard is referenced by the model codes, in addition to the information that is included in the codes with regard to fire doors. The model codes mandate the location of fire doors, and the amount of protection the opening protectives must provide, and NFPA 80 includes more specific information about the construction, testing, and maintenance requirements of the fire door assemblies.
The walls surrounding certain areas in a building are required to be fire-resistance-rated. For example, exit enclosures for stairwells are typically surrounded by fire-resistant construction, to protect the stairwell as a safe means of egress during a fire. In some applications, fire-resistant partitions separate a room or area from the rest of the building to slow the spread of smoke and flames. An example of this would be an apartment building, where each apartment is surrounded by fire barriers which help to keep the fire contained to the apartment of fire origin, while protecting adjacent apartments and the egress corridor. These fire barriers would be of no value if the openings passing through the walls were not protected by fire door assemblies.
The video below is an introduction to the requirements for fire door assemblies. Most of the concepts addressed in the introductory video are covered in more detail in other segments of the ShortCodes course.
