PHYSICAL DATA
| Boiling point (‘F.) |
: @ 1 atm –109.3F (-78.5oC) |
| Triple point (‘F.) |
: @ 1 atm 76 (-56.66oC and 75.1 lbs/sqin.a) |
| Vapor pressure (psia) |
: @ 68F (20C) 831 psia (56,5 atm)
|
| Solubility in water |
: @ 68F (20C), 1 atm 87.8% by volume |
| Vapor density (lb/cu ft) |
: @ 68F (20C), 1 atm 0.115 |
| Specific gravity (AIR=1) |
: @ 68F (20C), 1 atm 1.53 |
| Liquid density (lb/cu ft) |
: @ -35 (-37oC) 11 atm 68.74 |
| Specific gravity (H20=1) |
: Solid @ -110F (-79C),1 atm 1.56 |
| Appearance and odor |
: Carbon dioxide
is colorless and odorless as gas or
liquid.
It is stored in containers under its
own vapor pressure.
If the pressure is suddenly relieved,
the liquid rapidly
cools as it evaporates and sublimes,
forming dry ice
at –109.3F (-78.5C) |
HEALTH HAZARD DATA
THRESHOLD LIMIT VALUE
TLV = 5000 ppm [TLV-STEL (Short Term Exposure
Limit) = 15000 ppm (1.5% by vol.)]
SYMPTOMS IF INGESTED, CONTACTED
WITH SKIN, OR VAPOR INHALED
Carbon dioxide does not
support life and may produce immediately
hazardous atmospheres. At a concentration
In excess of 1.5%, carbon dioxide may produce
hyperventilation, headaches, visual disturbances,.
tremor, loss of consciousness and, death.
Symptoms of exposure In the concentration
ranges of 1.5-5% may be highly variable,
but typical symptoms of carbon dioxide intoxication
include the following:
| Co2 concentration |
: Symptoms |
| 3-6% |
: Headaches, dyspnea, perspiration |
| 6-10% |
: Headache, dyspnea, perspiration,
tremors, visual disturbance, unconsciousness |
| Over 10% |
: Unconsciousness |
If the concentration of carbon
dioxide exceeds 10%, unconsciousness can
occur without warning, preventing self-rescue.
At much higher concentrations, carbon dioxide
displaces the oxygen in air below levels
necessary to support life.
TOXICOLOGICAL PROPERTIES
Carbon dioxide is a minor but
important constituent of the atmosphere,
averaging about 0.03% or 300 ppm by volume.
At higher concentrations it affects the
respiratory rate. Additional symptoms are
described above.
RECOMMENDED FIRST AID
TREATMENT
Persons suffering from the
toxic effect of carbon dioxide should be
moved to areas with normal atmosphere. SELF
CONTAINED BREATHING APPARATUS MAY BE NECESSARY
TO PREVENT TOXIC EXPOSURE OR ASPHYXIATION
OF RESCUE WORKERS. Assisted respiration
and supplemental oxygen should be given
if the victim is not breathing. Frozen tissues
should be flooded or soaked with tepid water
(105-115F; 41-46C). DO NOT USE HOT WATER.
Cryogenic burns, which result in blistering
or deeper tissue freezing, should be seen
promptly by a physician.

| Hazardous polymerization |

STEPS TO BE TAKEN IN
CASE MATERIAL IS RELEASED OR SPILLED
Carbon dioxide in small quantities will
vaporize leaving behind carbon dioxide "snow"
(a combination of dry ice and water ice
where atmospheric moisture is present).
Ventilate indoor areas well to avoid hazardous
carbon dioxide concentrations. Ventilate
well and avoid contact with cold vapors
or dry ice. Carbon dioxide is a heavy gas
and will remain in low spots without assisted
ventilation
WASTE DISPOSAL METHOD
When disposing of bulk quantities
of Carbon dioxide from refrigerated storage
tanks, always dispose of Carbon dioxide
outside in a well ventilated location away
from work areas, where vapors can disperse,
vent to the atmosphere slowly since rapid
depressurization of the container will cause
the formation of solid carbon dioxide (dry
ice) internally, requiring longer periods
to vaporize and risking to the vessel.
SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION
(Specify type)
Use self-contained breathing
apparatus in oxygen-deficient atmospheres
or where carbon dioxide exceeds 1.5%. CAUTION!
Respirators will not function. Use may result
in asphyxiation.
VENTILATION (Natural
or mechanical where gas is present)
| Local exhaust - Special |
May be useful at point
sources of Co2 vapors. |
| Mechanical - General - Other |
Where low lying areas are not naturally
ventilated. Vents should be situated
to avoid higher than normal concentration
of helium in work areas. |
| Protective Gloves |
Loose fittings gloves of impermeable
material such as leather when working
with cold liquid, solid, or vapor. |
| Eye protection |
Safety glasses are recommended when
handling high-pressure cylinders and
in areas where vapors are discharged. |
| OTHER PROTECTIVE EQUIPMENT |
None |
SPECIAL PRECAUTIONS
& PACKINGS
SPECIAL LABELING INFORMATION
Carbon dioxide shipment must be in accordance
with Department of Explosives, Government
of India regulations using the "NON
FLAMMABLE GAS" label.
SPECIAL HANDLING RECOMMENDATIONS
Prevent contact of liquid Co2,
cold vapors, or carbon dioxide "snow"
with exposed skin. Prevent entrapment of
liquid in closed systems. Never use direct
flame to heat a compressed gas. Also avoid
dragging, rolling, or sliding, even for
a short distance. Use a suitable hand truck.
SPECIAL STORAGE RECOMMENDATIONS
Store liquid containers in
well ventilated areas. Storage should not
be in heavy traffic areas to prevent accidental
knocking over or damage from passing or
falling objects. Storage areas should be
free of combustible material. Avoid exposure
to areas where salt or other corrosive chemicals
are present.
*
See the conditions of storage licence in
Form III with reference to Rule 49 &
50 of SMPV (V) Rules.
OTHER RECOMMENDATIONS
OR PRECAUTIONS
In applications where temperatures
less than -20F (-29C) are expected, avoid
the use of carbon steel and other materials
which become brittle at low temperatures.
Compressed gas should not be refilled except
by qualified producers of compressed gases.
Shipment of a compressed gas without the
permission of the owner is a violation of
DoE. The atmosphere in areas in which Co2
gas may be vented and collected should be
tested with a portable or continuous monitoring
Co2 gas analyzer
