If during the course of handling or moving cylinders, one or more of them should start to fall over,
stand well back and allow them to fall. Do not attempt to catch them, or serious back injury may
result.
Cylinders in the horizontal position should be righted carefully. Crouch at the valve end
of the cylinder,
check that the valve is closed and that the valve guard is securely attached, then keeping a straight
back lift that end of the cylinder whilst walking forward. Ensure that the cylinder is secure before
walking away.
Cylinders should never be dropped or hit sharply, and all due care taken to avoid knocking them over.
Cylinders should never be subjected to direct heating or allowed to come into contact with electrical
supplies.
6.2.3 Leaking Cylinder
If a cylinder is found to be leaking and the cylinder is stored inside then it must be removed from the
building and allowed to vent off to atmosphere. However, because the helium is an asphyxiate, under
no circumstances must any person enter the room that the cylinder is in unless wearing a self
contained breathing apparatus.
If it is possible to open the doors to allow the gas to escape outside then this is best done. It is
important to ensure the safety of all other persons likely to be affected by the leaking gas and is
therefore best to evacuate the people concerned until all of the helium has dissipated. If the cylinder
cannot be removed to outside and nobody is able to enter the room, then contact the fire brigade who
have the correct equipment. Do not allow anybody to re-enter the evacuated area until it is safe to do
so.
6.3 Fire
If there is a fire the gas in the cylinder will not burn. However there is a risk of the cylinder exploding.
As the cylinder gets hotter, the gas inside expands, and will eventually reach a point where the walls
of the cylinder cannot hold the pressure any longer, causing an explosion. If at all possible, remove
the cylinders from the fire to a safe position well away from the heat, as it is the heat that causes the
expansion. If it is not possible to remove the cylinders then the cylinders must be kept cool by using a
hose to pour water on the cylinders until the fire brigade arrive where they will take over. Remove all
unnecessary staff to a safe distance and keep the public away.
6.4 Site Safety
The site should be kept clean and tidy. Members of the public should not be allowed to wander
around freely.
All ropes and ratchet straps should be tidied away when not in use.
Systems and procedures should be in place for maintenance and repairs.
•
Electrical equipment must be isolated and locked off with the key held by the person working on
the equipment.
•
All personnel must be informed of any work being carried out
