Fire Door Ratings and Classified Openings.
Fire door openings are classified by their locations in a building. Location determines the length of exposure protection required, based on the potential fire hazard of that particular area. The opening classifications are shown below.
1.Most exterior doors do not require fire rating, unless there is the potential for fire exposure from the outside of the building.
2.Fire-Rated doors are required to be self closing and positive latching.
3.The wall, door frame, door and hardware must all be fire rated.
