The batch house storage room is where dry glass colorant <br />chemicals are stored. Chemicals included cobalt oxide and nickel oxide. <br />Melting Furnace <br />The glass melting furnace utilizes batch materials in the manufacturing of glass. This is a <br />continuously operating process. The furnace (ceramic refractory lined) melts and holds <br />liquid glass. The refractory brick does not contain hexavalent chromium. <br />As the liquid glass leaves the furnace, it is cooled and formed. The cooling and forming <br />processes are extensive but are necessary in order to manufacture glass that meets the <br />required specification. <br />Glass Forming & Lehr <br />A number of compressed gases are used in the manufacturing. of glass. Their addition to <br />the process occurs during either the forming of the glass or annealing process. <br />Sulfur Dioxide (SO2) is injected into the glass bath lift out area beneath the glass sheet to <br />aid in the prevention of roll marks on the bottom side of the glass, and to prevent the glass <br />from sticking to the rolls. A SO2 dispensing port is located outside the lehr. Two 500 Ib <br />cylinders are located there: one for dispensing and one on standby. There is a third 1 500 <br />Ib cylinder located about 50 feet away as a back up (not connected)Glass Capping <br />The continuous ribbon of glass must be cut into various sizes. The capping table uses <br />cross cutters to do the cutting across the ribbon, with slit cutters to cut width of the ribbon. <br />The glass breaks along the line of least resistance when it is flexed over a high <br />roll. Cutting oil is used in this process - one 55 gallon drum and a 220 gallon tote are <br />located in this area. <br />H:\profile\My Documents\500 E. louise ave (CIA LOF)\9-25-13\909R5003 Emergency Response Procedures.doc <br />Page 5 of 67 <br />Paper Copies are Not Controlled unless stamped in RED "Controlled Document'.
