Emergency Overview:
|
| Carbon
Dioxide is a colorless gas or a colorless, cryogenic liquid.
At low concentrations, the gas is odorless. At higher
concentrations it has a sharp, acidic odor. It will act as an
asphyxiant and an irritant. Carbon
Dioxide is a powerful cerebral dilator. At concentrations
between 2 and 10%, Carbon Dioxide can cause nausea, dizziness,
headache, mental confusion, increased blood pressure and
respiratory rate. Above 8% nausea and vomiting appear.
Above 10%, suffocation and death can occur within
minutes.
Contact with the cold gas can cause
freezing of exposed tissue. Moisture in the air can lead to
formation of carbonic acid that can irritate the eyes. All
forms of Carbon Dioxide are noncombustible.
Carbon Dioxide is heavier than air and should
not be allowed to accumulate in low lying areas. |
|

cells and central nervous system may occur due to the presence
of carbon dioxide. |

RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE
VICTIMS OF EXPOSURE TO THIS PRODUCT WITHOUT ADEQUATE PERSONAL
PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing
Apparatus should be worn.
Remove victim(s) to fresh air, as quickly as
possible.
If not breathing qualified personnel should administer
artificial respiration. Get medical attention. |
| If breathing is difficult,
administer oxygen. |
|
| Ingestion:
|
| No first aid should be
needed. |

media for surrounding fire. |
|
| Special procedures:

apparatus required. |
| Firefighters should wear the
usual protective gear. |

| Explosion Data
|
|
| Sensitivity to
mechanical impact: |
| Avoid impact against
container. |
|
| Explosive power:
|
| Closed containers may rupture
or explode due to pressure build-up when exposed to extreme
heat. |
|
|
|
|
| Leak/Spill:
|
| Evacuate all non-essential
personnel. |
| Stop leak without risk.
|
| Wear
gloves and goggles |
Use a self-contained
breathing apparatus.
|
Ventilate area.
Monitor the surrounding area for Carbon Dioxide and Oxygen
levels. Carbon Dioxide must be below the 5000 PPM TLV/PEL level shown
in Section 2 and Oxygen must be at least 19.5% before
personnel may be allowed into the area without self-contained
breathing apparatus.
|
| A portion
of the released liquid may form dry ice. Clear the area
and allow the solid to sublime/ evaporate and dissipate. If
the area must be entered by emergency personnel,
self-contained breathing apparatus, Kevlar gloves, and
appropriate foot and leg protection must be worn. Solid pieces
of dry ice may be picked up with tongs and gloves, placed into
a thermally insulated and vented container and moved to a safe
disposal location. |
|
|
|
|
| Handling procedures
and equipment: |
|
Never allow any unprotected part of the body
to touch uninsulated pipes or vessels that contain cold
fluids. The extremely cold metal of the container will cause
moist flesh to stick fast and tear when one attempts to
withdraw from it.
|
Protect
system components against physical
damage. Check all hoses and transfer equipment before filling
them with the liquid. Replace any worn or cut hoses prior to
use.
|
|
Liquid Carbon Dioxide is extremely cold and is
under pressure. A leak will result in the formation of "Dry
Ice" particles which will be forcibly ejected from the system,
possibly injuring the operator. A complete hose failure can
result in a large release of Carbon Dioxide and violent
movement of the hose and associated equipment, which may cause
severe injury or death. Special care must be taken when
depressurizing and disconnecting hoses.
|
|
Releasing the contents of a liquid-filled line
to atmospheric pressure may result in the formation of a solid
dry ice plug in the line. This plug will prevent further
removal of the liquid behind the plug, resulting in either an
unexpected, rapid release of Carbon Dioxide as the line warms,
or the catastrophic failure of the line as the liquid warms
behind the plug. Sufficient vapor pressure must be applied and
maintained behind the liquid before opening a discharge valve.
This action will prevent the depressurization of the liquid to
the point of solid formation before it exits the line.
|
| Use adequate ventilation.
|
| Avoid inhalation.
|
| Never work on a pressurized
system. |
| If there is a leak, close the
upstream valve, blow down the system by venting to a safe
place, then repair the leak. |
|
| Storage
requirements: |
| Use
storage containers, piping, valves and fittings designed for
storage and distribution of Liquefied Carbon Dioxide and
vaporized (Gaseous) Carbon Dioxide. |
