The components of a medical oxygen cylinder are the cylinder itself, which is measured on water capacity. Cylinders have various numbers stamped into the shoulder of the cylinder. The serial number is one of the main numbers. They also have manufacturer dates or test dates as well. The cylinders have a 10-year life cycle before they go in for re-testing. If they go in for re-testing and pass the test, then they get signed off for another 10 years. The colour of the cylinder is pure white with a white shoulder. So completely white cylinder. The cylinders have various labels on them. They will have a barcode label which we use to track our cylinders and it also includes all of that information on that shoulder of the cylinder. So serial numbers and test dates and such like.

It will also have a label with the supplier's name on it and contact details. You will also have a product label on the cylinders with some safety information, details of what's exactly contained within the cylinder, what the product is. It will have the manufacturer's contact details on it. It will have a fill date and expiry date of the product. So that's the gas inside the cylinder.

It will have a pressure, which is how high the cylinder is charged to. And it will have a contents label as well, telling you how much gas is inside that cylinder. The cylinders are fitted with regulators. Most cylinders these days are fitted with what we would call an integral regulator. So the regulator's attached to the cylinder, cannot be removed.

The regulator has a gauge on it, which tells you at all times how much gas is contained within the cylinder. It will have a flow selector on the top of the cylinder, which allows you to select the flow rate per minute depending on the requirements. It will have a quick connector Schrader connect and you can plug various ancillary devices into that, things like resuscitators, or demand valves. The other thing on the regulator is a charging point, which will be blanked off but behind a dust cap. And that is where the cylinders are filled at the production facility.
