Gulf of Mexico Shelf Region Waste Management Procedures Oxygen Contents The section on Oxygen contains the following: Topic Version 2, October 2011 See Page Before You Begin 2 Oxygen (compressed) 3 Oxygen, refrigerated liquid (cryogenic liquid) 7 Page 1 of 9 Gulf of Mexico Shelf Region Waste Management Procedures Oxygen Before you begin Description Inert gas transported in: cylinders as a compressed gas tanks as a cryogenic liquid. Regulated by DOT only because of the pressure and temperature at which it is transported. Leaks of oxygen (while a temperature or pressure hazard to personnel) are not a serious environmental issue. Twenty-one percent of the air we breathe is oxygen. Category Unused oxygen is not a waste. Any quantity of oxygen remaining in the cylinder or tank can be used or should be returned to the vendor as unused product. Analysis Not required Accumulation Compressed oxygen should remain in the original cylinder Cryogenic liquid oxygen should remain in the original tank If cylinder is unusable [damaged], empty and punctured or has the valve removed: It may be placed in scrap metal bin. Waste Reduction Minimize wasteful practices (i.e., overuse or excessive usage, return excess purchases to vendor) Use all of contents Send to another location that can use it Return empty cylinder (or tank) or any unused portion of a cylinder (or tank) to vendor Disposal Recordkeeping Version 2, October 2011 Return to vendor for credit Maintain a copy of manifest offshore and at shore base facilities while shipping papers are active.
