C04-5 Appendix III IITF Chemistry Laboratory Cylinders for Disposal.pdf

This is an appendix documenting gas cylinders designated for disposal from the IITF Chemistry Laboratory. The inventory includes 19 total cylinders across ten distinct gas types and mixtures, ranging in size from lecture bottles to large cylinders. The cylinders are manufactured by Scott Company, General Gases, Matheson TRI GAS, HNU Systems Inc., and Scotty II Analyzed Gases. Specific contents include UN 1956 N.O.S mixture calibration gas (4 large cylinders from Scott Company), unknown calibration medium cylinders (3 from Scott Company), UN1072 oxygen (1 medium from General Gases), UN 1066 nitrogen in multiple sizes (3 total units across large, medium, and lecture bottle sizes), non-flammable/non-toxic span gas (2 lecture bottles from HNU Systems Inc.), CAN Mix 114 Ethylene 99.5% (1 lecture bottle), and CAN Mix 112 Butane 99.0% (1 lecture bottle). The appendix includes photographs of the various cylinders in their current condition, showing both large pressurized cylinders and smaller lecture bottles with visible weathering and corrosion consistent with items awaiting disposal.
