Section 3 : HAZARD IDENTIFICATION
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.

Route of entry:
Inhalation, skin and eye contact.
Effects of acute exposure  
Eye contact:
Can cause frostbite (liquid form).
Vapor may cause a stinging sensation.
Skin contact:
Can cause frostbite (liquid form).
No adverse effects from gas.
Inhalation:
May cause dizziness.
Asphyxiant.
Can cause vomiting.
May result in unconsciousness.
May cause excitation, excess salivation, rapid breathing.
May cause headaches and drowsiness.
May cause stinging of the nose and throat.
Ingestion:
Not a likely route of exposure.
Effects of chronic exposure:
Damage to retinal ganglion cells and central nervous system may occur due to the presence of carbon dioxide.
Reproductive effects:
Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental animals.
Section 4 : FIRST AID MEASURES
Skin contact:
Remove contaminated clothing.
Treat for frostbite if necessary by gently warming affected areas.
Consult a physician.
Eye contact:
Immediately flush eyes with plenty of water for at least 15 minutes.
Consult an ophthalmologist.
Inhalation:

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.
Not considered a potential route of exposure.
Section 5 : FIRE FIGHTING MEASURES
Flammability:
Not flammable.
Conditions of flammability:
Will not burn.
Extinguishing media:
Use appropriate extinguishing media for surrounding fire.
Special procedures:
Self-contained breathing apparatus required.
Firefighters should wear the usual protective gear.
Cool fire exposed containers with water spray.
Personnel should be evacuated, if necessary, to upwind area.
Remove containers from fire area if without risk.
Auto-ignition temperature:
Not applicable.
Flash point (C), method:
Not applicable.
Lower flammability
limit (% vol):
Not applicable.
Upper flammability
limit (% vol):
Not applicable.
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.
Section 6 : ACCIDENTAL RELEASE MEASURES
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.
Section 7 : HANDLING AND STORAGE
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.
Section 8 : EXPOSURE CONTROLS / PERSONAL PROTECTION
Precautionary Measures  
Gloves/Type:
Insulated neoprene.
Respiratory/Type:
NIOSH/ MSHA air purifying respirator for concentrations up to 10 times TLV; air supplied for higher concentrations.
Eye/Type:
As per local regulations.
Footwear/Type:
Safety boots per local regulations.
Clothing/Type:
Wear adequate protective clothes.
Other/Type:
Eye wash facility should be in close proximity.
Emergency shower should be in close proximity.
Ventilation requirements:
Mechanical ventilation is satisfactory. Ensure oxygen concentration remains above 19.5% and Carbon Dioxide concentration does not exceed 5000 ppm,
Local exhaust at points of emission preferred.
