As the fire separation distance increases, the fireresistance rating requirements are reduced, based on the- occupancy group under consideration. [Table at end of document.] Recommended Practice for Protection of Buildings from Exterior Fire Exposures This recommended practice provides recommendations concerning separation distances between buildings to limit exterior fire spread based on exterior openings and other construction features. It also addresses means of protection, including types of protection, evaluation, selection, and application. It also addresses means of protection, including the evaluation, selection, and application of different types of protection. Fire Walls. A common path of travel exists in the initial portion of the exit access where a space is arranged so that occupants within that space can travel in only one direction to reach any of the exits or to reach the point at which they have the choice of two paths of travel to two different remote exits. If a building designer desires to have a larger building without upgrading the construction type and without installing sprinklers throughout the building, they would be required to use fire walls to separate the building into, building code wise, two separate buildings.

(PDF, 253 KB), Fire Protection Research Foundation report: "Separation Distances in NFPA Codes and Standards" (PDF, 4 MB) For our Group A-3 building, which could be a church or gymnasium, the required fire wall would have to have an hourly fire resistance rating of 3 hours per Table 706.5. You are not permitted to print copies of the material from this subscription. Enclosed parking garages do not have this exception and would require a 1-hour exterior wall unless the fire separation distance is 30 feet or greater.
