�_ , <br /> CITY OF EVERETT ' <br /> BUILDING DIVISION <br /> Title Date <br /> evator Cable Slots for High-Rise Buildings March 24, 1988 <br /> U.B.C. 1807(h)(3)/5105 <br /> Code Section: 1807(h) ELEVATORS (3) h 5105. Elevator hoistways <br /> shall not be vented through an elevator machine room. Cable slots <br /> entering the machine room shall be sleeved beneath the machine room <br /> floor and extend to not less than 12" below the shaPt vent to <br /> inhibit the passage of smoke into the machine room. <br /> DISCUSSION: <br /> The sleeve system prescribed by the Code for high-rise buildings <br /> does not, in fact, inhibit smoke from entering the machine room. <br /> The elevator industry has designed a gasket system consisting of <br /> the installation of 1" high-density Pelt sandwiched between two <br /> pieces of 16 gauge galvanized shaet steel, slotted to allow passage <br /> of the hoist cables only. This assembly overlaps the Ploor <br /> penetration on all sides a minimun of 2 inches. <br /> POLICY: : It shall be the policy of the City of Everett that the <br /> ass�b y described above is the equivalent to that prescribed by <br /> the Code and will be allowed by the Building Official without <br /> Purther appeal. <br /> Issued by: <br /> ?im Tyler <br /> Building Official <br /> 3226H <br />
