1. ALL medical oxygen cylinders (in Australia) are black in colour with a white neck or shoulder. If the cylinder is not as above then it should not be used.
2. A full cylinder is denoted by a plastic dust cover around the valve of the cylinder. The cylinders are considered empty if this cover is removed. Once the dust cover has been removed dispose of the cover and do not place it back on the cylinder. Leave the cover on until the cylinder is required for use.
FITTING THE REGULATOR
1. Remove the dust cover from the cylinder. The regulator will only fit on to the cylinder one way. The indexing pin holes on the cylinder correspond to the indexing pins on the regulator.
