Product Manual - Perma-Cyl
®
w/ FlexFill™ Piping Option
General
While Chart equipment is designed and built to the most
rigid standards, no piece of mechanical equipment can
ever be made 100% foolproof. Strict compliance with
proper safety and handling practices are necessary when
using a cryogenic manifold device or other compressed
gas equipment. We recommend that all of our customers
re-emphasize safety and safe handling practices to all their
employees and customers. While every possible safety
feature has been designed into the Perma-Cyl
®
MicroBulk
Storage System w/ FlexFill
™
Piping Option and safe
operations are anticipated, it is essential that the customer
carefully read and fully understand all Warning and Caution
notes listed below.
Warning! The Perma-Cyl tank, with its
stainless steel support system
is designed, manufactured, and
tested to function normally for
many years of service. It is never
safe to drop a liquid cylinder or
let it fall over in oxygen or any
cryogenic service. In the event
a liquid cylinder is inadvertently
dropped, tipped over, or abused,
slowly raise it to its normal
vertical position and immediately
open the vent valve to release
any excess pressure in a safe
manner. As soon as possible,
remove the liquid product from
the vessel in a safe manner.
If the vessel has been used in
oxygen service, purge it with an
inert gas (nitrogen). If damage is
evident or suspected, return the
unit to Chart prominently marked
“LIQUID CYLINDER DROPPED,
INSPECT FOR DAMAGE”.
Warning! Any welding that is done on the
outside of the Perma-Cyl System
can cause loss of vacuum and
will VOID any warranty on the
unit.
Warning! Before removing cylinder parts
or loosening ttings, completely
empty the liquid cylinder of
liquid and release the entire
vapor pressure in a safe manner.
External valves and ttings can
become extremely cold and may
cause painful burns to personnel
unless properly protected.
Personnel must wear protective
gloves and eye protection
whenever removing parts or
loosening ttings. Failure to do
so may result in personal injury
because of extreme cold and
pressure in the cylinder.
Caution! Only use replacement equipment
which is compatible with liquid
oxygen and has been cleaned
for oxygen use. Do not use
regulators, ttings, hoses, etc.,
which have been previously
used in compressed air service.
Failure to comply with these
instructions may result in serious
damage to the liquid cylinder and
personal injury.
Caution! All valves on an empty Perma-
Cyl system should always be
kept closed to protect the inner
vessel and plumbing from being
contaminated.
Safety Bulletin
Portions of the following information are extracted from
Safety Bulletin SB-2 from the Compressed Gas Association,
Inc. Additional information on oxygen, nitrogen, argon, and
cryogenics is available from the CGA.
Cryogenic containers, stationary or portable, are from time
to time subjected to assorted environmental conditions of
an unforeseen nature. This safety bulletin is intended to call
attention to the fact that whenever a cryogenic container
is involved in any incident whereby the container or its
safety devices are damaged, good safety practices must be
followed. The same holds true whenever the integrity or
function of a container is suspected of abnormal operation.
Incidents which require that such practices be followed
include: highway accidents, immersion of a container in
