SPRINKLERS The car house has been completely equipped with automaticaisle sprinklers in the longitudinal bays and curtain sprinklersalong the transfer table pits. The aisle sprinkler heads areattached at intervals of 7 ft. to pipe lines suspended from theceiling girders at about the height of the tops of the car win-dows. One line of sprinklers extends down the center of eachbay, but no heads are installed in the aisles between tracksfrom which the concrete roof columns rise. Three curtainsprinkler heads protect the end of each bay at the transfer tablepit. The sprinkler system which was installed by the Inter-national Sprinkler Company, Philadelphia, Pa., is supplied withwater from a 35,000-gal. tank on the roof over the oil andsand storage.
