EMERGENCY OVERVIEW
Odorless, colorless, non-flammable liquefied gas. Simple Asphyxiant 鈥? This product does not contain
oxygen and may cause asphyxia if released in a confined area. Maintain oxygen levels above 19.5%.
Carbon dioxide acts as a weak narcotic at high concentrations (30,000 ppm). Inhalation of high
concentrations of carbon dioxide can cause reduced hearing acuity, changes in respiration and
increased blood pressure and pulse. Contact with liquid product may cause frostbite or freezing
burns in exposed tissues. Contents under pressure. Use and store below 125 掳F.

EYE EFFECTS: Contact with evaporating liquid may cause frostbite.
SKIN EFFECTS: Contact with liquefied product may cause frostbite upon evaporation. Frostbite effects are a
change in color of the skin to gray or white, possibly followed by blistering. Skin may become inflamed and
painful.
INGESTION EFFECTS: Ingestion is unlikely. Contact with liquid may cause frostbite.
INHALATION EFFECTS: Depending on concentration and duration of exposure carbon dioxide may cause
increased respiration, headache, mild narcotic effects, increased blood pressure and pulse, and asphyxiation.
Symptoms of overexposure to carbon dioxide become more apparent when atmospheric oxygen is decreased to
15-17%. Chronic harmful effects are not known from repeated inhalation of concentrations below the
PEL/TLV.
Product may also act as asphyxiant. Effects of oxygen deficiency may include: rapid breathing, diminished
mental alertness, impaired muscular coordination, faulty judgement, depression of all sensations, emotional
instability, and fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness
may result, eventually leading to convulsions, coma, and death.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: None known.
POTENTIAL ENVIRONMENTAL EFFECTS: Not expected to be toxic to fish and wildlife.
4. First Aid Measures
EYES: Never introduce ointment or oil into the eyes without medical advice! In case of freezing or cryogenic
"burns" caused by rapidly evaporating liquid, DO NOT WASH THE EYES WITH HOT OR EVEN TEPID
WATER! Remove victim from the source of contamination. For contact with small amounts of liquid, open
the eyelids wide to allow the liquid to evaporate. For contact with large amounts, rinse with a low pressure
stream of cool water for 15 minutes. Refer the victim to an ophthalmologist for treatment and follow up. If the
victim cannot tolerate light, protect the eyes with dark glasses. The use of bandages is not recommended as
keeping the eyelids closed or exerting pressure on the eyelid may cause further damage.
SKIN: For dermal contact or frostbite: Remove contaminated clothing and flush affected areas with lukewarm
water. DO NOT USE HOT WATER. A physician should see the patient promptly if contact with the product
has resulted in blistering of the dermal surface, frostbite, or in deep tissue freezing.
INGESTION: A physician should see the patient promptly if frostbite has occurred.

INHALATION: PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE TO CARBON DIOXIDE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH
SELF-CONTAINED BREATHING APPARATUS. Conscious persons should be assisted to an
uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important.
Unconscious persons should be moved to an uncontaminated area, given mouth-to-mouth resuscitation and
supplemental oxygen. Further treatment should be symptomatic and supportive.

FIRE AND EXPLOSION HAZARDS:
Nonflammable. Cylinder may vent rapidly or rupture violently from pressure when involved in a fire situation.
EXTINGUISHING MEDIA:
None required. Use as appropriate for surrounding materials.
FIRE FIGHTING INSTRUCTIONS:
Firefighters should wear respiratory protection (SCBA) and full turnout or Bunker gear. Continue to cool fire-
exposed containers until well-after flames are extinguished.
6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment (See Section 8). Stop the flow
of gas or remove cylinder to outdoor location if this can be done without risk. Ventilate enclosed areas. If
leak is in container or container valve, contact the appropriate emergency telephone number listed in Section 1
or call your closest BOC location.
7. Handling and Storage
Electrical Classification: Non-Hazardous.
This liquefied gas is noncorrosive and may be used with all common structural materials.
Dry carbon dioxide can be handled in most common structural materials. Moist carbon dioxide is generally
corrosive by its formation of carbonic acid. For applications with moist Carbon Dioxide, 316, 309 and 310
stainless steels may be used as well as Hastelloy 庐 A, B, & C, and Monel 庐. Ferrous Nickel alloys are slightly
susceptible to corrosion. At normal temperatures carbon dioxide is compatible with most plastics and
elastomers. Some metals (i.e.: carbon steel) will become brittle at low temperatures and easily fracture.
Use only in well-ventilated areas in accordance with manufacturer's and BOC instructions. Do not tip, drag,
slide or roll cylinders. Use a suitable hand truck for cylinder movement. Valve protection caps must remain in
place unless container is secured with valve outlet piped to use point. If user experiences any difficulty
operating container valve discontinue use and contact supplier. Do not insert any object (i.e.: screwdriver) into
valve cap openings as this can damage the valve causing leakage.

PRODUCT NAME: CARBON DIOXIDE, REFRIGERATED LIQUID
Use a pressure reducing regulator when connecting cylinder to lower pressure piping or systems. Do not heat
containers by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap
in the discharge line to prevent hazardous back flow into the system.
Protect containers from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked
areas and emergency exits. Containers should be stored upright and firmly secured to prevent falling or being
knocked over. Full and empty cylinders should be segregated. Use a "first in-first out" inventory system to
prevent full containers being stored for excessive periods of time.
Never allow any unprotected part of the body to touch uninsulated pipes or vessels containing cryogenic fluids.
The extremely cold metal will cause the flesh to stick and tear when you attempt to remove it.
Stationary customer site vessels should be operated in accordance with the manufacturer's and BOC's
instructions. Do not attempt to repair, adjust or in any other way modify the operation of these vessels. If there
is a malfunction or other type of operations problem with the vessel, contact the closest BOC location
immediately for assistance.
Due to the extremely cold liquid, uninsulated transfer lines may condense air. The liquefied air may flash off
nitrogen, leaving an oxygen enriched liquid. Do not allow the liquefied air to contact oils, greases, or other
combustible materials such as asphalt and motor oil.
For additional information, consult the Compressed Gas Association (CGA) pamphlets P-1, G-6 Carbon
Dioxide, G-6.1 Standard for Low Pressure Carbon Dioxide Systems at Consumer Sites, G-6.3 Carbon Dioxide
Filling and Handling Procedures for Beverage Plants, and SB-2. Never carry a compressed gas cylinder or a
container of a gas in cryogenic liquid form in an enclosed space such as a car trunk, van or station wagon. A
leak can result in a fire, explosion, asphyxiation or a toxic exposure.
8. Exposure Controls, Personal Protection
ENGINEERING CONTROLS:
Use local exhaust in combination with general ventilation to control air contaminants to at or below acceptable
exposure guidelines and maintain atmospheric oxygen at 19.5%.
EYE/FACE PROTECTION:
Wear chemical goggles with faceshields where contact with liquid is possible.
SKIN PROTECTION:
Insulated gloves are recommended for cryogenic liquids.
RESPIRATORY PROTECTION:
For emergency release use a positive pressure NIOSH approved air-supplying respirator systems (SCBA or
airline/escape bottle) using a full-face mask and at a minimum Grade D air.
OTHER/GENERAL PROTECTION:
Safety shoes, emergency eyewash stations

peroxide and aluminum or magnesium may explode.
HAZARDOUS POLYMERIZATION: Will not occur.
11. Toxicological Information
SKIN AND EYE: Gas is non-irritating. Liquid may cause tissue damage.
INHALATION: Acidosis, adrenal cortical exhaustion, and other metabolic stresses have resulted from
prolonged continuous exposure to 1-2% carbon dioxide (10,000 ppm 鈥? 20,000 ppm). The ACGIH TLV of
5,000 ppm is expected to provide a good margin of safety from asphyxiation and undue metabolic stress
provided sufficient oxygen levels are maintained in the air. Increased physical activity, duration of exposure,
and decreased oxygen content can affect systemic and respiratory effects resulting from exposure to carbon
dioxide.
OTHER: Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and
experimental animals.
Exposure of female rats to 60,000 ppm carbon dioxide for 24 hours has produced toxic effects to the embryo
and fetus in pregnant rats. Toxic effects to the reproductive system have been observed in other mammalian
species at similar concentrations.
Chronic, harmful effects are not known from repeated inhalation of low (3 to 5 molar %) concentrations.
