Storage of Medical Gases

  • At temperatures below -7 degrees centigrade liquefaction and separation of the individual gases in the cylinder can occur .This may lead to delivery of an uneven mixture. If an entonox cylinder has been stored at low temperatures it should be layed flat at a temperature > 5 degrees centigrade over 24 hours and then inverted several times in order to allow remixing of the gases.
  • The gases must be stored in an appropriate facility, CD cylinders should be stored flat.
  • Store cylinders in a well-ventilated dry environment. Appropriate signage should be written on the storage area.
  • Keep away from sources of heat or ignition.
  • Transportation of gas cylinders should follow guidelines with the appropriate sticker in the vehicle. Take care when moving cylinders. Do not roll them.
  • They should be aligned in correct date of replenishment order. Gases should be replaced once they become 1/4 full. It is wise to have a spare cylinder of oxygen stored as occasionally a valve may leak on a cylinder.
