Ten Points about Cylinder Safety
1
Read labels and Material Safety Data Sheet
(MSDS) before use.
2
Store upright and use in well ventilated,
secure areas away from pedestrian or vehicle
thoroughfare.
3
Guard cylinders against being knocked
violently or being allowed to fall.
4
Wear safety shoes, glasses and gloves when
handling and connecting cylinders.
5
Always move cylinders securely with an
appropriate trolley. Take care not to turn the
valve on when moving a cylinder.
6
Keepinacool,wellventilatedarea,away
from heat sources, sources of ignition and
combustible materials, especially flammable
gases.
7
Keepfullandemptycylindersseparate.
8
Keepammonia-basedleakdetection
solutions, oil and grease away from cylinders
and valves.
9
Never use force when opening or closing
valves.
10
Don’t repaint or disguise markings and
damage. If damaged, return cylinders to BOC
immediately.
Cylinder Valve Safety
When working with cylinders or operating
cylinder valves, ensure that you wear
appropriate protective clothing – gloves, boots
and safety glasses.
When moving cylinders, ensure that the valve is
not accidentally opened in transit.
Before operating a cylinder valve:
•Ensurethatthesystemyouareconnecting
the cylinder into is suitable for the gas and
pressure involved.
•Ensurethatanyaccessories(suchashoses
attached to the cylinder valve, or the system
being connected to) are securely connected.
A hose, for example, can potentially flail
around dangerously if it is accidentally
pressurised when not restrained at both ends.
•Standtothesideofthecylindersothat
neither you nor anyone else is in line with the
back of the cylinder valve. This is in case a
back-plug is loose or a bursting disc vents. The
correct stance is shown in the diagram above.
When operating the cylinder valve:
•Openitbyhandbyturningthevalvehand-wheel
anti-clockwise. Use only reasonable force.
•Ensurethatnogasisleakingfromthecylinder
valve connection or the system to which the
cylinder is connected. DO NOT use ammonia-
based leak detection fluid as this can damage
