CYLINDER ADVICE

1. On no account should anyone attempt to loosen or remove a valve from a charged
(gas filled) cylinder. Additionally, on no account should anyone remove a valve from
an empty cylinder unless they have the specific authority to do so, and the necessary
knowledge and equipment to avoid damage to either the valve or the cylinder.
2. Luxfer gas cylinders supplied for SCUBA and SCBA are designed specifically for
that purpose and must not be used under any circumstance for any other purpose
whatsoever & must only be used by properly trained personnel.
3. A cylinder containing gas under pressure could be dangerous if used for anything other
than its intended purpose. All SCUBA and SCBA cylinders must be used with a breathing
regulator so as to protect the diver from the full pressure of gas inside the cylinder.
4. Do not alter or modify this gas cylinder, to do so may cause harm or danger to
the user or individuals. Alterations or modifications invalidate the original design and
approvals given by regulatory authorities. The pressure containment of the cylinder
may be seriously impaired by unauthorized modification.
5. Do not attempt to saw, drill holes or weld attachments onto the cylinder.
6. Do not place this gas cylinder in hot or boiling water, close to heat sources such as
radiant heaters, storage heaters, radiators, open fires or appliances that generate heat etc.
7. Do not discharge a cylinder in an uncontrolled manner as this may result in the pressure
jet causing injury & risk to a diver through reduced breathing potential.
8. Do not completely empty a cylinder & leave the valve open as this may allow the
ingress of moisture into the cylinder, which could facilitate corrosion.
9. Ensure that a cylinder is only filled with dry, oil free air from an approved storage
source or via a correctly serviced & functioning compressor.
10. Should a cylinder leak after filling, as shown by a stream of bubbles leaving the cylinder
after immersion in a tank of water, under no circumstances should the cylinder be used, even
if the bubbles are small & infrequent. In such cases, the cylinders must be depressurised &
taken to an Authorized Re-Test Centre for examination/testing by a competent person.
11. The stamped markings on a cylinder are important for the servicing and filling of
the cylinder and must not be altered or changed
12. Do not stand or store gas cylinders for anything but short periods of time on concrete floors,
wet decking or wet wooden racks or stillages. Cylinders should be stored on dry surfaces.
13. Do not throw the cylinder, or drop it from a height as it may cause damage to the
cylinder & or/valve. Indents & other damage may result from impacts, which in turn
could impair the integrity of the cylinder.
14. Do not throw the cylinder onto a fire for it may rupture violently.
15. Gas cylinders should not be used for target practice. Do not throw darts or fire
arrows, air guns or more powerful weapons at gas cylinders. To do so is irresponsible
and could result in a serious incident.
16. Do not attempt to crush squeeze or run over a gas cylinder. Do not use it as a battering tool,
hammer, doorstop, load support, as a stop to prevent closure of scissors action machinery,
jacks or other equipment, or for any other purpose other than for which it was made.
