It is the in[ent of the U. B. C. that the basemen[ be actually used <br />and classified as a Group A Occupancy in order to require sprinklers where the <br />basement is laz�er than 1500 square feet in t7oor area. <br />In the case of a multioccupancy basement, which includes a Group :� Occu- <br />pancy, the entire area af [he basement would require sp:inklers. <br />3. Exhibition and display raoms. This code requirement came about as a <br />direct :esult of the �(cCormick Place Fire on Januarv I6, t967, in Chicaeo. <br />McCormick Place consis[ed of [hree levels and con[ained a main exhibit area of <br />3?0,000 squaze fze[ on the upper fevel. Both the upper level and lower level <br />were in the final stages of readiness for a housewares exhibition and werc <br />heavily laden wiv� combustibles when the r"ue broke out. The fire was reoorted <br />to have originated in [he storage area behind an exhibie boo[h on the upper Ievel. <br />The upper leve( �vas almost totally desvoyed, and considerable dam�ge oc- <br />curred to the lower level (2). <br />Ordinarily, assembly occupancies are mnsidered eo have a very lo�a fire <br />loading, and [hereiore automatic fire-sprinklerproteccion has natbeen required <br />for the building. The need for built-in fire suppression in an assembly occu- <br />pancy which c:�� be used for exhibi[ion or display purposes was c;early orought <br />out by �� r, �1cCormick Place fire. The display booths are mostoften cons¢ucted <br />wich combustible materials, and the storaee area behind the booths is a recep[a- <br />cle for combuseible ma[erials and packing ooxes. Thus, withouc buil[-in fire <br />suppression che lazee quan[i[ies of combuscible materials and laree areas com- <br />bine [o creaee an eseessive hazard. � <br />4. Stairs. As assembly occupr, cies cone�in large numbers of occupants, it is <br />imperacive tha[ the exits de av;,daoie for use �nd stainvays no[ be subjected [o <br />any fire hazards which could render them unusable. Th�s, the code requires <br />sprinklers to be ins[alled in endosed usable soace below oroverastairwav in the <br />lisred assembly occupancies [o prorece aeainst the common prac«ce of sroring <br />combustible materials in [hese enclosed soaces. The reference to Section 3309 <br />(� is ro c�ll �[[en[ion to the code prohibi[ion aeainst enclosed usable space under <br />a s[ainvay in an exic enclosure. <br />�. Other areas.
