3. Hazards Identification
EMERGENCY OVERVIEW
Oxygen levels below 19.5% may cause asphyxia. Carbon dioxide exposure can cause nausea and
respiratory problems. High concentrations may cause vasodilation leading to circulatory collapse.

Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
No adverse effects anticipated.
SKIN EFFECTS:
No adverse effects anticipated.
INGESTION EFFECTS:
No adverse effects anticipated.
INHALATION EFFECTS:
Carbon dioxide is the most powerful cerebral vasodilator known. Inhaling large concentrations causes rapid
circulatory insufficiency leading to coma and death. Asphyxiation is likely to occur before the effects of carbon
dioxide overexposure. Chronic, harmful effects are not known from repeated inhalation of low concentrations.
Low concentrations of carbon dioxide cause increased respiration and headache.
Effects of oxygen deficiency resulting from simple asphyxiants 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.
Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental
animals.

4. First Aid Measures
EYES:
Never introduce oil or ointment into the eyes without medical advice! If pain is present, refer the victim to an
ophthalmologist for further treatment and follow up.
SKIN:
No adverse effects anticipated.
INGESTION:
Not anticipated.
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.

6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user's equipment,
be certain to purge piping with inert gas prior to attempting repairs. 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
MSDS: G-8
Revised: 6/7/96 Page 3 of 7
PRODUCT NAME: CARBON DIOXIDE, GAS
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 ?A, B, & C, and Monel ? Ferrous Nickel alloys are slightly
susceptible to corrosion. At normal temperatures carbon dioxide is compatible with most plastics and
elastomers.
Use only in well-ventilated areas. Carbon dioxide vapor is heavier than air and will accumulate in low areas.
Valve protection caps must remain in place unless container is secured with valve outlet piped to use point. Do
not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure reducing
regulator when connecting cylinder to lower pressure (<3000 psig) piping or systems. Do not heat cylinder 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 cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked
areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 125oF (52oC).
Cylinders 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 cylinders being stored
for excessive periods of time.
For additional storage recommendations, consult Compressed Gas Association's Pamphlet P-1.
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.
Maximum use for potable water 100 mg/l.

IDLH (Carbon Dioxide): 50,000 ppm
ENGINEERING CONTROLS:
Use local exhaust to prevent accumulation of high concentrations so as to reduce the oxygen level in the air to
less than 19.5% and the carbon dioxide concentration below the exposure limit.
EYE/FACE PROTECTION:
Safety goggles or glasses as appropriate for the job.
SKIN PROTECTION:
Protective gloves of any material appropriate for the job.
