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 the valve. Approved leak
detection fluid, can be obtained from a BOC Gas & Gear 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
BOC and arrange for the cylinder to be returned to BOC.
