SECTION 3. HAZARDS IDENTIFICATION
Carbon dioxide is a nonflammable liquefied compressed gas packaged in cylinders under its own
vapor pressure of 838 psig at 70 掳F (21.1 掳C). High concentrations can cause rapid suffocation and
can also increase respiration and heart rate. Contact with liquid may cause frostbite. Avoid
breathing gas. Self contained breathing apparatus (SCBA) may be required by rescue workers.

POTENTIAL HEALTH EFFECTS:
INHALATION: Carbon dioxide is an asphyxiant. Concentrations of 10% or more can produce
unconsciousness or death.
EYE CONTACT: Contact with liquid or cold vapor can cause freezing of tissue.
SKIN CONTACT: Contact with liquid or cold vapor can cause frostbite.
ROUTE OF ENTRY: Inhalation

Pub # 310-408
SYMPTOMS: Headache, sweating, rapid breathing, increased heartbeat, shortness of breath,
dizziness, mental depression, visual disturbances, and shaking.
CHRONIC EFFECTS: None established.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: None
CARCINOGENICITY: Carbon dioxide is not listed by NTP, OSHA or IARC.
SECTION 4. FIRST AID
INHALATION: Persons suffering from overexposure should be moved to fresh air. If victim is not
breathing, administer artificial respiration. If breathing is difficult, administer oxygen. Obtain
prompt medical attention.
EYE CONTACT: Contact with liquid or cold vapor can cause freezing of tissue. Gently flush eyes
with lukewarm water. Obtain medical attention immediately.
SKIN CONTACT: Contact with liquid or cold vapor can cause frostbite. Immediately warm
affected area with lukewarm water not to exceed 107 掳F.
NOTES TO PHYSICIAN: There is no specific antidote. Treatment for overexposure should be
directed at the control of symptoms and the clinical condition.
SECTION 5. FIRE AND EXPLOSION
FLASH POINT: AUTOIGNITION: FLAMMABLE LIMITS:
Not Applicable Nonflammable
EXTINGUISHING MEDIA: Carbon dioxide is nonflammable and does not support combustion.
Carbon dioxide is an extinguishing agent for class B and C fires. Use extinguishing media
appropriate for the surrounding fire.
HAZARDOUS COMBUSTION PRODUCTS: None known.
FIRE FIGHTING PROCEDURES: Evacuate personnel from danger area. Carbon dioxide is
nonflammable. If possible, without risk, remove cylinders from fire area or cool with water. Self
contained breathing apparatus (SCBA) may be required for rescue workers.
UNUSUAL HAZARDS: Upon exposure to intense heat or flame, cylinder will vent rapidly and or
rupture violently. Most cylinders are designed to vent contents when exposed to elevated
temperatures. Pressure in a container can build up due to heat and it may rupture if pressure relief
devices should fail to function.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Evacuate all personnel from affected area. Increase ventilation to release area and monitor
oxygen level. Use appropriate protective equipment (SCBA). If leak is from cylinder or cylinder
valve call the Air Products emergency telephone number. If leak is in user鈥檚 system close cylinder
valve and vent pressure before attempting repairs.
SECTION 7. HANDLING AND STORAGE
STORAGE: Cylinders should be stored upright in a well-ventilated, secure area, protected from the
weather. Storage area temperatures should not exceed 125 掳F (52 掳C). Storage should be away
from heavily traveled areas and emergency exits. Avoid areas where salt or other corrosive
materials are present. Valve protection caps and valve outlet seals should remain on cylinders not
connected for use. Separate full from empty cylinders. Avoid excessive inventory and storage
time. Use a first-in first-out system. Keep good inventory records.
HANDLING: Use a suitable hand truck for cylinder movement. Never attempt to lift a cylinder by
its valve protection valve cap. Never apply flame or localized heat directly to any part of the
cylinder. Do not
MSDS # 1005 Carbon Dioxide Page 2 of 6
Pub # 310-408
allow any part of the cylinder to exceed 125 掳F (52 掳C). High temperature may cause damage to
cylinder and/or premature failure of pressure relief device which will result in venting of cylinder
contents. If user experiences any difficulty operating cylinder valve discontinue use and contact
supplier. Never insert an object (e.g., wrench, screwdriver, pry bar, etc.) into valve cap openings.
Doing so may damage valve causing a leak to occur. Use an adjustable strap wrench to remove
over-tight or rusted caps.
Only the proper CGA connections should be used, never use adapters. Use piping and equipment
adequately designed to withstand pressures to be encountered. If liquid product is being used
ensure steps have been taken to prevent entrapment of liquid in closed systems. The use of
pressure relief devices may be necessary. Use a check valve or other protective apparatus in any
line or piping from the cylinder to prevent reverse flow.
Carbon dioxide is compatible with all common materials of construction. Pressure requirements
should be considered when selecting materials and designing systems.
Use a 鈥淔ULL鈥?, 鈥淚N USE鈥?, and 鈥淓MPTY鈥? tag system on cylinders. This will reduce the chances of
inadvertently connecting or operating the wrong cylinder.
SPECIAL REQUIREMENTS: Always store and handle compressed gases in accordance with
Compressed Gas Association, Inc. (ph. 703-979-0900) pamphlet CGA P-1, Safe Handling of
Compressed Gases in Containers. Local regulations may require specific equipment for storage or
CAUTION: Compressed gas cylinders shall not be refilled except by qualified producers of
compressed gases. Shipment of a compressed gas cylinder which has not been filled by the owner
or with the owner鈥檚 written consent is a violation of federal law.
SECTION 8. PERSONAL PROTECTION / EXPOSURE CONTROL
ENGINEERING CONTROLS: Provide ventilation and/or local exhaust to prevent accumulation of
carbon dioxide concentrations above 5000 ppm.
Emergency Use: Self contained breathing apparatus (SCBA) or positive pressure airline
with mask and escape pack are to be used in oxygen deficient atmosphere. Air purifying
respirators will not provide protection.
EYE PROTECTION: Safety glasses are recommended when handling, connecting, or
disconnecting cylinders, and when pressurizing systems
OTHER PROTECTIVE EQUIPMENT: Safety shoes and leather work gloves when handling

SECTION 11. TOXICOLOGICAL INFORMATION
Carbon dioxide is an asphyxiant. It initially stimulates respiration and then causes respiratory
depression. High concentrations result in narcosis. Symptoms in humans are as follows:
1% Slight increase in breathing rate
2% Breathing rate increases to 50% above normal. Prolonged exposure
can cause headache and tiredness.
3% Breathing increases to twice the normal rate and becomes labored.
Weak narcotic effect. Impaired hearing, headache, increase in blood
pressure and pulse rate.
4-5% Breathing increases to approximately four times the normal rate,
symptoms of intoxication become evident and slight choking may be
5-10% Characteristic sharp odor noticeable. Very labored breathing,
headache, visual impairment and ringing in the ears. Judgment may be
impaired, followed within minutes by loss of consciousness.
50-100% Unconsciousness occurs more rapidly above 10% level. Prolonged
exposure to high concentrations may eventually result in death from
SECTION 12. ECOLOGICAL INFORMATION
No adverse ecological effects are expected. No adverse ecological effects are expected. Carbon
dioxide does not contain any Class I or Class II ozone depleting chemicals. Carbon dioxide is not
listed as a marine pollutant by DOT (49 CFR 171).
SECTION 13. DISPOSAL
UNUSED PRODUCT / EMPTY CYLINDER: Return cylinder and unused product to supplier. Do not
