4.6 Typical Cylinder Handling
Checklist
CAUTION: Only persons who have had
specictraininginthesafetyofmedicalgases,
manual handling techniques and cylinder
changing procedures should be allowed to
change cylinders on medical gas manifolds or
medical equipment.
• Safety shoes should be worn at all times. When
moving larger cylinders, wear heavy protective
gloves (preferably textile or leather). Keep all
items clean and grease/oil free.
• Do not smoke or use naked lights.
• When handling smaller cylinders, the use of
protective gloves may be inconvenient. Extra
care should be taken to avoid injury and to
make sure that hands are free from oil or
grease BEFORE the cylinders are handled.
• Do not knock cylinders against each other or
other solid objects.
• Do not drop or drag the cylinders.
• Do not use cylinders as rollers or wheel
chocks.
• Do not lift any cylinder by its valve or cap
• Use appropriate trolley for larger cylinders.
4.7 Cylinder Operation
CAUTION: Undue force should not be
used to open or close cylinder valves, or to attach
connectors to cylinders.
CAUTION: ALL cylinder valves should be
opened gently. TAPPING the operating key GENTLY
with a soft-faced (copper) mallet is acceptable but
undue force should not be used. If it is obvious
that injury or damage could arise from trying
to open a sticking valve, the cylinder should be
removed from service and returned to the supplier
as a faulty cylinder.
CAUTION: Opening cylinder valves SLOWLY
will prevent a sudden rise in pressure in the
system. It is at this time when there will be most
stress on components and when most explosions
will occur due to adiabatic compression of any oil
or grease that may be present.
4.7.1 The cylinder valve should be FULLY opened
(slowly, anticlockwise) using the appropriate
cylinder key or handwheel where tted and then
turned clockwise a quarter turn.
CAUTION: If there is any leakage of gas
the cylinder should be removed from service and
returned as faulty. DO NOT attempt to tighten
gland nuts etc, as this may cause damage to the
valve.
4.7.2 To close the valve, turn the spindle or
handwheel clockwise. Hand pressure only should
be used to close the valve.
5. Maintenance Procedures
A competent person who is conversant with
the maintenance of high-pressure medical gas
installations and any special national conditions,
which may apply, must carry out all maintenance.
Preventative maintenance contracts are available
from BEACONMEDÆS for installations within the
U.K., overseas distributors will be able to supply
similar contracts in other areas.
WARNING: OBTAIN A WORK PERMIT
(OR EQUIVALENT FOR OVERSEAS) BEFORE
COMMENCING ANY WORK ON A MEDICAL GAS
INSTALLATION.
5.1 Daily Inspection
5.1.1 Check visual indicators for correct function
and damage.
5.1.2 If the ERM is observed to be in operation
on its “emergency reserve” bank, replacements
for empty cylinders should be made available
immediately.
5.1.3 Check manifold pressure gauges for
abnormal conditions.
5.1.4 Check ERM for unusual noises or
vibrations.
5.2 Weekly
5.2.1 Check that all cylinders are properly
secured and that batch labels are correct and in
date.
5.3 Quarterly
5.3.1 Ensure that:
(a) when the duty (primary) manifold is
running the reserve (secondary) manifold cylinders
are full;
