Series MicroBulk Delivery System
Safety Summary
While every possible safety precaution has been taken to
ensure safe operation and maintenance of the Orca CO
2
Series delivery system, it is imperative that all persons
having contact with the Orca delivery system become
thoroughly familiar with all maintenance, safety precautions,
and procedures contained in this product manual. If for any
reason any part or parts of this manual become confusing
or the information provided is not completely understood
contact a Technical Service Representative at Chart Inc.
1-800-400-4683 before proceeding with the operation or
repair of the vessel.
Compatibility and Cleaning
Always keep the Orca delivery system clean and free from
grease and oil. Use care when cleaning with high-pressure
water or steam cleaning equipment. DO NOT direct the
cleaning nozzle into the electronic components. When
replacing components, use only parts which are considered
compatible with liquid oxygen. Do not use regulators,
ttings, or hoses, which were previously used in compressed
air or carbon dioxide environments. Use only oxygen
compatible sealants on threaded connections. All new joints
should be leak tested with an oxygen compatible leak test
solution at a minimum of 35 psig. Failure to comply with
these instructions may result in serious personal injury,
death, or damage to the container.
Caution! Before removing any parts or
loosening of ttings empty the
cryogenic container of liquid
contents and release any vapor
pressure in a safe manner.
External valves and ttings
can become extremely cold.
Personnel must wear protective
gloves and eye protection
whenever removing parts or
loosening ttings. Failure to do
so may result in personal injury
due to the extreme cold and tank
pressure. Accidental contact of
liquid gases to skin or eyes may
cause a freezing injury similar to
a burn.
Warning! If cryogenic liquid or cold boil-
o gas contacts a worker’s skin
or eyes, the aected tissues
should be promptly ooded or
soaked with tepid water (105-
115°F; 41-46°C). DO NOT USE
HOT WATER. A physician should
examine cryogenic burns that
result in blistering or deeper
tissue freezing promptly.
Warning! Do NOT use open ame in or
around the plumbing cabinet.
Use warm water if thawing of
components is necessary.
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 at www.cganet.com.
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.
Good safety practices dictate the contents of a damaged or
suspect container be carefully emptied as soon as possible.
Under no circumstances should a damaged container be left
with product in it for an extended period of time. Further, a
damaged or suspect container should not be relled unless
the unit has been repaired and re-certied.
Incidents which require that such practices be followed
include: highway accidents, immersion of a container in
water, exposure to extreme heat or re, and exposure to most
adverse weather conditions (earthquake, tornadoes, etc.) As a
general rule, whenever a container is suspected of abnormal
operation, or has sustained actual damage, good safety
practices must be followed.
