T;he value ob[ained in Number 2 above may be reduced by up [o SO% for cor,lece �' <br /> au[oc�a[ic sprinkler protection. Where buildings are ei[her fire resistive or non- <br /> combus[i�le construction, and have a lou fire hazard, [he reduction may be up to 75i. <br /> The percentage reduction made for an au[omar.ic sprink�er system vill depend upo� the <br /> ex[ent [o which the sys[em is judged to reduce [he possibility of fires spreadin¢ <br /> uithin and beyond [he fire area. Normally this reduc[ion w:11 not be the maximuc� <br /> allowed wichout proper sys[em supervision including ua[er flow and valves. <br /> 4. To [he value obtained in No. 2 above a percentage should be added for <br /> struc:ures exposed e:ithin 150 feet by the fire area under consideration. This <br /> percentage shall depend upon the height, area, and constructio❑ of the buildin <br /> being er.posed, [he separation, openings in [he exposed buildin <br /> exposure, the g�s� <br /> buildin Pr�vision of automa[ic sprinklers and/or ou'tsidessprinklerseinCthef <br /> 8�s) exposed, the occupancy of the exposed building(s) , and che effect of <br /> hillside locations on the possible spr�ad of fire. <br /> The percen[age for any one side generally shou]d not exceed the following lini[s <br /> for the separa[ions shown: <br /> Separation <br /> 0-10 fee[ Percentage <br /> 11-30 ZS% <br /> 31-60 Z� <br /> 61-100 15 <br /> 101-150 10 <br /> 5 <br /> The total percentage shall be the sum of the percentages for all sides, but shall <br /> ; noC exceed 75X. <br /> 5• The value obtained ia No. 2 above is reduced by [he percentage (if any) <br /> determined in No. 3 above and increased by the percentage (if any) determined in <br /> No. 4 above. <br /> The fire flow shall not exceed 12,000 gpm nor be less [han 500 gpm. <br /> Note 1: The guide is not expected to necessarily provide an adequate value for <br /> lumber yards, petroleum storage, refinertes, grain elevators, and large <br /> chemical plants but may indicate a minimum value for these haza:ds. <br /> Note 2: Judgment must be used for business, inductrial, and other occupancie� <br /> not specifically mentioned. <br /> Nu[e 3: Consideration should be given to the configuration of the building(S) <br /> being considered and to [he fire c'epartment accessibility. <br /> Note 4: Wood frame struct_ures separatad by less than 10 feet shali be considered <br /> as one fire area. <br /> No[e 5: Party Walls:- Normally an unpierced party (co!rmon) aa11 nay varran[ up <br /> to a lOX exposure charge. <br /> � <br /> . -Z- <br />
