<br />Appendix A is deleted. <br /> <br />Appendix B is amended to read as follows: <br /> <br />Appendix B <br />Fire Flow Calculations <br /> <br />The following information is a summary and is provided to assist in <br />understanding the required fire flow calculation method. Refer to the Insurance <br />Services Organization's (ISO) Fire Suppression Rating Schedule for actual <br />calculations. Where any question or discrepancy exists Fire Suppression Rating <br />Schedule should be followed. <br /> <br />The ISO's method for calculation of fire flows consider the square footage, <br />type of construction, type of occupancy, exposure, and communication of the <br />building to be protected. The required fire flow ("F") is determined as follows where: <br /> <br />A effective area <br />C = construction coefficient* <br />o = occupancy factor* <br />E = exposure factor* <br />M = communication factor* <br />F = required flow <br /> <br />F= 18(0)(E)(M)(C)(vlA) <br /> <br />The effective area is the sum of 100% of the ground floor and 50% of all additional <br />floors. The final result is rounded to the nearest 250 gpm up to 2500 gpm and to the <br />nearest 500 gpm beyond 2500 gpm. <br /> <br />*See the ISO Fire Suppression Rating Schedule for details on calculation. <br /> <br />Residential Construction <br /> <br />F or one and two family dwellings not exceeding two stories in height, the following <br />fire flows shall be used. <br /> <br />Distance between buildings Required fire flow <br />Over 1 00 feet 500 gpm <br />31 - 100 feet 750 gpm <br />11 - 30 feet 1000 gpm <br />10 feet or less 1500 gpm <br /> <br />C:\TEMPlmark's tire code 2-6-02.doc <br /> <br />- 11 - <br />
