Typical Cylinder Handling
Checklist
CAUTION: Only persons who have had
specific 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 must 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 an appropriate trolley for larger cylinders.
4.6
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.
4.6.1
The cylinder valve should be FULLY opened
(slowly, anticlockwise) using the appropriate cylinder
key or handwheel where fitted 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.
4.6.2
To close the valve, turn the spindle or
handwheel clockwise. Hand pressure only should
be used to close the valve.

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 control panel is observed to be
operating on its backup bank, replacements for
the empty cylinders must be made available
immediately.
5.1.3
Check manifold pressure gauges for
abnormal conditions.
5.1.4
Check control panel 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;
(b)
all system pressures are normal;
(c)
all alarms are showing as normal;
(d)
the manifold line isolating valve is open;
and
