- Do not drop
cylinders or permit them to strike anything violently.
transported by truck must be fastened securely in an upright position
so that they will not fall or strike each other.
- Always chain
gas cylinders upright to a wall, cylinder truck, cylinder rack
- Caps used
for valve protection should be kept on the cylinders at all times
except when the cylinder is actually being used or charged. Cylinders
cannot be transported without safety caps. A cylinder's cap should
be screwed all the way down on the cylinder's neck ring and should
fit securely. Do not lift cylinders by the cap. The cap is for
valve protection only.
- Do not use
cylinders for rolling, supports, or any purpose other than the
transportation and supply of gas.
- Open cylinder
valves SLOWLY. Do not use a wrench to open or close a hand wheel
type cylinder valve. If it cannot be operated by hand, the valve
should be repaired. Cylinders returned to Stores with damaged
valves will be repaired and repair charges will be charged back
to user department.
- Do not attempt
to repair cylinder valves or their relief devices while a cylinder
contains gas pressure.
- Before attaching
cylinders to a connection, be sure that the threads on the cylinder
and the connection mate are of a type intended for the gas service.
- Do not permit
oil or grease to come in contact with cylinders or their valves.
- Do not charge,
ship or use any cylinder which is not provided with a legible
decal that identifies its contents.
should be stored in a well ventilated area away from flames, sparks
or any source of heat or ignition. Keep cylinders away from electrical
- Do not expose
cylinders to an open flame or to any temperature above 130 degrees
- Oxygen cylinders
(empty or full) in storage should be seperated from fuel-gas cylinders
and combustible materials by a minimum distance of 20 feet or
by a barrier at least 5 feet high having a fire-resistance rating
of at least one-half hour.
- Do not store
flammable gas cylinders with oxygen or nitrous oxide cylinders
adjacent to oxygen charging facilities.
- Full and
empty cylinders of all gases should be stored seperately and identified
by signs to prevent confusion.
may be stored outdoors but should be protected from the ground
to prevent bottom corrosion. Where extreme temperatures prevail,
cylinders should be stored so they are protected from the direct
rays of the sun.
should not be exposed to continuous dampness, stored near salt
or other corrosive chemicals or fumes. Corrosion may damage cylinders
and cause their valve protection caps to stick.
use the proper regulator for the gas in the cylinder.
- Always check
the regulator before attaching it to a cylinder. If the connections
do not fit together readily, the wrong regulator is being used.
- Always "crack"
the cylinder valve (open it slightly and close it immediately)
before attaching a gas regulator to any cylinder - except a hydrogen
or fuel gas cylinder.
- Wipe the
outlet with a clean, dry, lint-free cloth once the cylinder valve
has been cracked. The threads and mating surfaces of the regulator
and hose connections should be cleaned before the regulator is
- Always use
a cylinder wrench or another tightly fitting wrench to tighten
the regulator nut and hose connections.
- Do not crack
hydrogen and fuel-gas cylinder valves - merely wipe out the outlet
connections with a clean, dry, lint-free cloth.
- Attach the
regulator securely before opening the valve wide.
- Stand to
the side of the regulator when opening the cylinder valve.
- Tag leaking
cylinders or cylinders with stuck valves and move to a safe, secure
