Storage of cylinders
Cylinders should always be fully charged, ready for use. The minimum
pressure for stowage on an appliance is 250 bar.
Prior to recharging, cylinders must be examined externally for evidence
of high heat exposure, corrosion, scratches or gouges that have
penetrated to the carbon fibres or other evidence of significant damage.
If there is any doubt about the suitability of the cylinder for recharge,
return it to the State PPE&C Management Centre.
Always check to be sure the hydrostatic retest date is within the
prescribed period and that the cylinder is properly labelled to indicate its
hydrostatic test.
Filling cylinders
Cylinders can only be filled (charged) by trained persons at approved
filling stations.
The cylinder is hydrostatically tested every five years by the State PPE&C
Management Centre.
