scope:

The cleaning methods described in this publication are intended for cleaning equipment used in the production, storage, distribution, and use of liquid and gaseous oxygen. This publication does not replace or supersede any regulatory cleaning procedures or cleaning requirements specified by a national authority. Examples of such equipment (illustrative of the primary intent of this publication) are stationary storage tanks, cargo tankers, and tank cars; pressure vessels such as heat exchangers and rectification columns; and associated piping, valves, and instrumentation. The cleaning methods, however, are not limited to this equipment. With proper consideration or modification, these methods may be used in cleaning other oxygen service equipment such as cylinders, cylinder valves, regulators, welding torches, pipelines, compressors and pumps where regulatory requirements do not specify cleaning methods.
