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.
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 the
valve. Approved leak detection fluid can be obtained from a
Messer centre.
• When finished with the cylinder, close the cylinder valve by hand
by turning the valve hand-wheel in a clockwise direction. Use
only reasonable force.
Remember NEVER tamper with the valve. If you suspect the
valve is damaged, DO NOT use it. Report the issue to Messer
and arrange for the cylinder to be returned to Messer.
