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, 

fittings, 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 fittings empty the 

cryogenic container of liquid 

contents and release any vapor 

pressure in a safe manner. 

External valves and fittings 

can become extremely cold. 

Personnel must wear protective 

gloves and eye protection 

whenever removing parts or 

loosening fittings. 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-

off gas contacts a worker’s skin 

or eyes, the affected tissues 

should be promptly flooded 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 flame 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 refilled unless 

the unit has been repaired and re-certified.

Incidents which require that such practices be followed 

include: highway accidents, immersion of a container in 

water, exposure to extreme heat or fire, 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
