b. Extinguish any fire, flame our source of ignition (including
cigarettes, pipes and pilot lights) before changing the gas
cylinder.
c. Change cylinders with caution.
d. Ensure that the gas cylinder valve(s) is/are closed before
disconnecting an empty cylinder or before removing any
plastic cap or plug on the outlet connection of the
replacement cylinder.
Never use tools on cylinder valves, hand wheels or levers.
Note. Cylinders with threaded connections have a left-
hand thread. For cylinders with self-sealing clip-on valves,
ensure that the regulator cap is closed before
disconnection.
e. Ensure that the replacement cylinder connections are
gastight. Any leaking vapour will have a distinctive odour.
Test by brushing soapy water around the connections -
bubbles will form if vapour is leaking.
NEVER USE A NAKED FLAME
f. It is essential that the correct pressure regulator, with the
correct pressure setting and capacity for the installation,
be used in accordance with the manufacturers
instructions.
g. In the case of a pressure regulator or a gas appliance
which relies upon a sealing washer to maintain a gastight
joint, it is essential to check that the washer is present
and that it is sound and correctly positioned prior to
making the connection.
h. Where connections are designed to be tightened with a
spanner, it is essential that a spanner of the correct size is
used and that the union is firm - hand tightness is not
sufficient.
When self sealing valves are incorporated in a gas cylinder,
connections should be made in accordance with the
manufacturer's instructions and tools should not be used.
