SAFE HANDLING

Caution
O
nly use replacement equipment which is compatible
with liquid oxygen and has been cleaned for oxygen
use. Do not use regulators, fittings, hoses, etc., which
have been previously used in compressed air service.
Similarly, do not use oxygen equipment for com-
pressed air. Failure to comply with these instructions
may result in serious damage to the liquid cylinder.
Caution
Dura-Cyl/Cryo-Cyl Series cryogenic liquid cylinders
should be moved using an appropriate liquid cylinder cart
or dolly. Do not roll liquid cylinders by handling rings.
Dura-Cyl/Cryo-Cyl Series liquid cylinders must be used
and stored in a vertical position except for normal cart or
dolly movement. Do not lay, store, or ship a liquid cylinder
on its side. When necessary to transport a liquid cylinder
by truck, use a power lift gate, crane, or inclined ramp to
lower the liquid cylinder. If the truck bed and dolly are
not at the same height, do not attempt to manually lift or
slide a liquid cylinder on or off a tuck bed. Failure to com-
ply with these procedures may result in damage to the
liquid cylinder.
This section describes and illustrates proper cylinder
h
andling procedures. Major considerations for liquid
cylinder handling are summarized as follows:
•
Dura-Cyl/Cryo-Cyl Series should be moved only
by utilizing an appropriate cylinder cart, roller
base, or overhead hoist. See section 17 for ap-
proved equipment.
•
Do not roll a liquid cylinder by the handling ring.
•
Dura-Cyl/Cryo-Cyl Series cylinders should always
be stored and operated in a vertical position.
•
Never lay, store, or ship a cylinder on its side.
•
When loading (or unloading) a cylinder onto a
truck, use a power lift gate, crane, or an inclined
ramp. Never attempt to manually lift or slide a liq-
uid cylinder on or off of a truck bed.
Dura-Cyl/Cryo-Cyl Series liquid cylinder can be safely
handled by using a cylinder cart, roller base, or an
overhead hoist. When moving the unit, keep the unit
upright at all times except for those instances when it
is slightly tipped for loading or unloading.
Dura-Cyl/Cryo-Cyl Series liquid cylinders are durable
liquid cylinders designed to withstand common han-
dling; however, abusing a unit may damage the liquid
cylinder to the extent that it must be returned to the
factory for repair.
Preferred Lifting Procedure
The Dura-Cyl/Cryo-Cyl Series liquid cylinders are pro-
vided with a ring on the top of the liquid cylinder. The
ring is designed to protect the plumbing components
and should not be used to handle or lift the liquid cylin-
ders. The ring is attached to the cylinder with two or
four posts. Each post has a lifting hole in it that can
be used to lift or attach a handling cart.
To lift a Dura-Cyl/Cryo-Cyl Series liquid cylinder, at
-
tach the properly sized hooks and chains into both of
the holes and lift vertically. Figure A shows how a
chain system can be used to lift the liquid cylinder. The
spreading bar is the preferred method, but the double
chain system is acceptable.
