Ten Points about Cylinder Safety

1

Always read the labels and Safety Data Sheet 
(SDS) before use.

2

Store cylinders upright and use in 
well-ventilated, secure areas away from 
pedestrian or vehicle thoroughfares.

3

Ensure cylinders are appropriately secured 
and guarded against being knocked violently 
or being allowed to fall.

4

Wear safety shoes, glasses and gloves when 
handling, connecting and using cylinders.

5

Ensure cylinders are appropriately restrained 
to mechanical lifting/handling devices prior 
to movement.

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

Never repaint or disguise markings and 
damage on cylinders. 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. 

Ensure cylinder value is closed before moving 
or disconnecting equipment. 

Before operating a cylinder valve:

•  Ensure that the system you are connecting 

the cylinder into is suitable for the gas and 
pressure involved. 

•  Cylinder valves should not be open unless a 

pressure regulator has been fitted.

•  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
