Posted By Rich Bannister No cylinders should be stored on their sides due to the possibility of mechanical damage to the sides. The bottom of the cylinder is reinforced so that it can be stood on end but the sides aren't. Can't you just tie them to the sides of the cage for stability?

Posted By Coshh Assessor Can't they be stored on their sides in a rack designed for the purpose, to prevent them rolling or falling?

Posted By Son of SkyWalker Could I suggest a simpler approach. Ask your suppliers for their input. They should be able to tell you what is suitable and what is not.

Posted By stephen d clarke Hi, Take a look at the British Oxygen website at: http://www.bocindustrial.co.uk/ and specifically for medical oxygen at: http://www.bocsds.com/uk/sds/ The following will be found and I think in all the oxygen MSDS its the only one that outline whether storage should be horizontal or vertical and relates that to cylinder size E or F 6.4 special precautions for storage – compressed medical oxygen cylinders should be: Stored under cover, preferably inside, kept dry and clean and not subjected to extremes of heat or cold and away from stocks of combustible material. Stored separately from industrial and other non-medical cylinders. Stored to maintain separation between full and empty cylinders. Used in strict rotation so that cylinders with the earliest filling date are used first. Stored separately from other medical cylinders within the store F size cylinders and larger should be stored vertically. E size cylinders and smaller should be stored horizontally. Steve
