� cc G: }ligh onc-s[ory bul]dings:�- kfi en a building is sta[ed �s 1 = 2, or more <br /> stories, the number of s[c�r±es co be used ir. [he formula depends upon <br /> the use being made of the building. For er.ample consider a 1 = 3-story <br /> building. If the building, is being used for t�igh-p�led stock, or for <br /> rack storage, the building would probably be conside�•ed as 3 stories and, <br /> in addition, an increased �percentage for occupancy ma� be warraneed. <br /> However, if the build:.ng is being used for steel fabrica[ian and the extra <br /> height ie provided only to facilitate movement of objecta by a crane, the <br /> building would probab.ly be considered ac a 1-story building and a decreased <br /> nercentage for occupancy may be varrante�. <br /> Hote 7: If a building is expo�ed within 150 feet, normally some percentage increase <br /> for exposure will be made. <br /> ho[z 8: Where wood ehingle roofs could contribute to spreading firec, add 500 gpm. <br /> Note 9: Any noncombustible building is considered to warrant an 0.8 coefficient. <br /> Note 10: Dwellings;- For groupings of 1-family and small 2-family dwellings not <br /> exceeding 2 stories in height, the following short methad may be used. <br /> (For other residential buildings, the regular method should be used.) <br /> Exposure distances Suggested required fire flow <br /> Over 100' S00 gpm <br /> 31-100' 750-100Q <br /> 11-30' 1000-1500 <br /> 10' or less 1500-2000* <br /> *If the buildings are continuous, use a minimum of 2500 gpm. <br /> Also consider Note 8. <br /> Ouiline of Procedure <br /> A. Determine the type of constxuction. <br /> B. Determine the ground floor are!t. <br /> C. Determine the height in stories. <br /> D. Using tables in the Appendia, determine the required fire flov to the nearest 250 epn. <br /> E. De[ermine the increase or decrease for occupancy and apply to the value obtained <br /> in D above. Do not round off the ansWer. <br /> F. Determine [he decrease, if any, for sutomatic sprinkler protectioa. Do not round <br /> ,� off [he value. <br /> v� � Deteraine the to[al increase for exposures. Do not round oEf [he value. <br /> -3- <br />
