Exposing building. Tables 5.6.1(a) through 5.6.1(e) of NFPA 80A provide multiple allowable adjustments in the required separation distance. The appropriate table must be selected based on the construction of the exposed building. Since the exposed building is of combustible exterior construction, refer to Table 5.6.1(a). Since the required separation is 20 ft, a 50 percent reduction in spacing would be needed to accomplish the builder’s goal of a 10-ft separation. Per the table, the installation of an automatic exposure protection sprinkler system over the entire wall, including the glass windows, would allow for a 50 percent reduction in the required spacing.There are several factors that allow for reductions in the separation distance. These include fire-resistant exposed walls with 3-hour minimum resistance, automatic closers over wall openings with ¾-hour minimum protection, installing automatic sprinkler exposure protection over wall openings, or installing automatic sprinkler exposure protection over the entire exposed wall surface. Depending on which options are chosen and the construction of the exposed walls, the separation may be allowed to be reduced anywhere from 50 percent up to the elimination of the requirement for a separation distance altogether (0-ft separation). In reality, a 0-ft separation may not be allowed due to required property set-backs, fire department access, or local ordinances, so additional research is recommended.Where automatic sprinkler systems are utilized for exposure protection, NFPA 13, Standard for the Installation of Sprinkler Systems, gives designers some direction for protection of windows, wall surfaces, combustible cornices, and combustible roofs. Exposure protection sprinkler systems

A door that measures 3-ft wide by 7-ft high. The second floor contains three evenly spaced 3-ft by 4-ft windows. There are no internal fire separations. For simplicity, we will assume that the exposing building has a flat, noncombustible roof that will not contribute to the fire. The average fire loading in the building is 7 lb/ft2 (light severity) and the interior wall and ceiling finishes have an average flame spread index of 30 (moderate severity). Since the more severe of these two classifications must be used, the exposing building will be classified as having a moderate severity rating. Assume that the exposed building is of combustible exterior siding and is also two stories, 100-ft wide and 30-ft tall with two evenly spaced rows of three windows measuring 3-ft wide by 4-ft tall. The windows are ordinary single-plate glass windows that project inwards 2 inches from the exterior wall surface. In order to make full use of the property, the builder’s desired building separation is 10 feet.First: Calculate w/h and h/w for the exposing building.w = 100 feet h = 30 feet w/h = 100/30 = 3.33h/w = 30/100 = 0.30The larger of these two values must be used, so use w/h = 3.33Second: Calculate the percentage of openings for the exposing building.5 windows @ 3 ft x 4 ft = 5 x 3 x 4 = 60 ft21 door @ 3 ft x 7 ft = 3 x 7 = 21 ft2Total area of exposed side = 30 ft

Exterior end walls where no fire separations exist.” The height of the exposing structure should be the height expected to contribute to the exposing fire. These two dimensions are used to calculate the width/height (w/h) or height/width (h/w) ratio. The larger of the two ratios is used. The percentage of openings is calculated by taking the total surface area of door and window openings on the exposing wall divided by the total surface of the exposing wall and multiplying by 100. The larger of the w/h or h/w ratios, along with the severity and the percentage of openings are applied to Table 4.3.7.3 from NFPA 80A (see Figure 3 below) to figure the Guide Number. The Guide Number is multiplied by the lesser dimension of the width or the height of the exposing wall, and 5 feet is added to the product of those two numbers. This yields the required separation distance. Figure 3. Table 4.3.7.3. Guide Numbers for Minimum Separation Distances.

Figure 4 (the featured image at the top of this article) shows a two-story building with an exposing face that is 30-ft tall and 100-ft wide. The first floor has two evenly spaced windows measuring 3-ft wide by 4-ft high and

Our affordable, self-adhesive, laminated vinyl signs can save valuable time in an emergency situation by drawing attention to rated assemblies, life-saving apparatus, and other emergency supplies. Our signs indicate protective fire-rated assembly walls in your place of business to fire fighters, contractors, and inspectors. Additionally, they can prevent damage from accidental drilling and tearing. Fire Wall Signs are OSHA-compliant and made to the highest quality standards.Fire Wall Signs assumes no responsibility for the integrity of the wall upon which a sign may be affixed.703.5 Marking and identification.Where there is an accessible concealed floor, floor-ceiling or attic space, fire walls, fire barriers, fire partitions, smoke barriers and smoke partitions or any other wall required to have protected openings or penetrations shall be effectively and permanently identified with signs or stenciling in the concealed space. Such identification shall:Be located within 15 feet (4572 mm) of the end of each wall and at intervals not exceeding 30 feet (9144 mm) measured horizontally along the wall or partition. Include lettering not less than 3 inches (76 mm) in height with a minimum 3/8-inch (9.5 mm) stroke in a contrasting color incorporating the suggested wording, “FIRE AND/OR SMOKE BARRIER—PROTECT ALL OPENINGS,” or other wording.
