Nitrous oxide storage

Do not park trucks with mixed loads adjacent to oxygen or nitrous oxide storage areas except while loading or unloading.

The sources of acetylene, nitrous oxide, and sometimes air are usually steel cylinders of the compressed gases purchased from specialty gas or welders gas suppliers. Thus, several compressed gas cylinders are usually found next to atomic absorption instrumentation and the analyst becomes involved in replacing empty cylinders with full ones periodically. Safety issues relating to storage, transportation, and use of these cylinders will be addressed in Section 9.3.7. The acetylene required for atomic absorption is a purer grade of acetylene than that which welders use. 

Nitrous oxide is synthesized, or produced, by heating ammonium nitrate (NH4N03) and then condensing out the water and filtering impurities. The gas is then compressed and turned into liquid for storage in tanks, cylinders, or cartridges. 

Storage. Nitrous oxide is supplied under pressure in cylinders, which must be maintained below 25°C. Cylinders containing premixed oxygen 50% and nitrous oxide 50% (Entonox) are available for analgesia. The constituents separate out at -7°C, in which case adequate mixing must be assured before use. 

Storage and transport In addition to soiling, stains due to yellowing, caused by antioxidants in plastic films and cartons together with nitrous oxides in the air (combustion engines) and cationic substances " ...
