Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:SOLID CARBON DIOXIDE (DRY ICE), IS A
    WHITE, OPAQUE SOLID WHICH RELEASES COLORLESS GAS. THE SOLID
    SUBLIMATES TO GAS QUICKLY AT STANDARD CONDITIONS, FORMING FOG IN
    AIR. THE MAIN HAZARDS ASSOCIATED WITH  CARBON DIOXIDE ARE RELATED
    TO CARBON DIOXIDE GAS FORMATION AND THE COLD TEMPERATURE OF THE
    SOLID AND EVOLVED GAS. ACUTE:CONTACT WITH SOLID CARBON DIOXIDE OR
    COLD GAS CAN CAUSE FROSTBITE TO SKIN, EYES,  AND OTHER EXPOSED
    TISSUE. CARBON DIOXIDE GAS IS AN ASPHYXIANT AND POWERFUL CEREBRAL
    VASODILATOR. INHALING HIGH CONCENTRATIONS OF CARBON DIOXIDE CAN
    LEAD TO COMA OR DEATH. AT LOW CONCENTRATIONS INHALA TION CAN CAUSE
    (SEE TOXICOLOGICAL)
Explanation of Carcinogenicity:CARBON DIOXIDE IS NOT FOUND ON THE
    FOLLOWING LISTS: FEDERAL OSHA Z LIST, NTP, CAL/OSHA, IARC, AND
    THEREFORE IS NOT CONSIDERED TO BE, NOR SUSPECTED TO BE A
    CANCER-CAUSING AGENT BY THESE AGENCIES.
Effects of Overexposure:INHALATION: LOW CONC.: NAUSEA, DIZZINESS,
    VISUAL DISTURBANCES, SHAKING, HEADACHE , MENTAL CONFUSION,
    SWEATING, INCREASED HEARTBEAT, ELEVATED BLOOD PRESS., INCREASED
    RESPIRATORY RATE. HIGH CONC: MAY CA USE EYE IRRITATION, EYE DAMAGE,
    COMA, DEATH. REVERSIBLE EFFECTS ON ACID-BASE BALANCE IN BLOOD,
    BLOOD PRESS., AND CIRCULATORY SYSTEM. COLD GAS CONTACT: CAN LEAD TO
    FROSTBITE, DERMATITIS, RED, CRACKED,  IRRITATED SKIN, WITH EYES CAN
    CAUSE PAIN, REDNESS, BURNS, AND SEVERE EXPOSURE COLIC CAUSE
    BLINDNESS. MOIST AIR MAY LEAD TO CARBONIC ACID, AN EYE IRRITANT.
Medical Cond Aggravated by Exposure:DISORDERS INVOLVING THE "TARGET
    ORGANS" MAY BE AGGRAVATED BY CARBON DIOXIDE OVEREXPOSURE. TARGET
    ORGANS: RESPIRATORY SYSTEM, CARDIOVASCULAR SYSTEM, EYES.

=======================  First Aid Measures  =======================

First Aid:RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE
    TO THIS PRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. AT
    A MINIMUM, SELF-CONTAINED BREATHING APPARATUS PERSONAL PROTECTIVE
    EQUIPME NT SHOULD BE WORN. REMOVE VICTIM TO FRESH AIR, AS QUICK AS
    POSSIBLE. TRAINED PERSONNEL SHOULD GIVE OXYGEN OR CPR AS NECESSARY.
    IN CASE OF FROSTBITE, PLACE FROSTBITTEN PART IN WARM WATER. DO NOT
    USE HO T WATER. IF WARM WATER IS NOT AVAILABLE, WRAP THE AFFECTED
    PART IN BLANKETS. ENCOURAGE VICTIM TO GENTLY EXERCISE THE AFFECTED
    PART WHILE BEING WARMED. GET MEDICAL ATTENTION.

=====================  Fire Fighting Measures  =====================

Extinguishing Media:NON-FLAMMABLE, INERT GAS. USE EXTINGUISHING MEDIA
    APPROPIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:WEAR FIRE FIGHTING PROTECTIVE EQUIPMENT AND
    FULL FACE-PIECE SELF-CONTAINED BREATHING APPARATUS. COOL FIRE
    EXPOSED CONTAINERS WITH WATER SPRAY.
Unusual Fire/Explosion Hazard:CO2 DOES NOT BURN. CONTAINERS MAY BURST
    IN FIRE. DUSTS OF REACTIVE METALS (MAGNESIUM, ZIRCON, TITANIUM
    ALLOYS), MAY IGNITE AND EXPLODE IN PRESENCE OF CO2. MIXTURES OF CO2
    WITH SODIUM AND POTASSIUM ALL OYS ARE IMPACT SENSITIVE AND EXPLODE
    VIOLENTLY. IN PRESENCE OF MOISTURE, CESIUM OXIDE IGNITES ON CONTACT
    WITH CO2.

==================  Accidental Release Measures  ==================

Spill Release Procedures:UNCONTROLED RELEASES SHOULD BE RESPONDED TO BY
    TRAINED PERSONNEL USING PRE-PLANNED PROCEDURES. PROPER PROTECTIVE
    EQUIPMENT SHOULD BE USED. LOCATE AND SEAL SOURCE OF LEAKING GAS.
    ALLOW GAS, WHICH IS HE AVIER THAN AIR, TO DISSIPATE. MONITOR
    SURROUNDING AREA FOR CARBON DIOXIDE AND OXYGEN LEVELS. ATTEMPT TO
    CLOSE MAIN SOURCE VALVE PRIOR TO ENTERING AREA. IF NOT ABLE, ALLOW
    GAS TO RELEASE IN-PLACE.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

======================	Handling and Storage  ======================

Handling and Storage Precautions:DO NOT HANDLE SOLID CO2 WITH BARE
    HANDS. USE HEAVY GLOVES OR ICE TONGS. HANDLE BLOCKS OF DRY ICE
    CAREFULLY, AS INJURIES CAN OCCUR IF ONE IS ACCIDENTALLY DROPPED ON
    THE FEET. NEVER STORE DRY ICE IN A S TANDARD REFRIGERATOR, COOLER,
    OR FREEZER DESIGNED FOR FOOD STORAGE.
Other Precautions:CONTAINERS OF SOLID CARBON DIOXIDE SHOULD BE STORED
    UPRIGHT, FIRMLY SECURED TO PREVENT FALLING. CONTAINER SHOULD BE
    VENTED, NEVER STORE DRY ICE IN A GAS-TIGHT CONTAINER.TO PREVENT
    BUILD-UP  OF GAS. CO NTAINERS SHOULD BE THERMALLY INSULATED AND
    KEPT AT LOWEST POSSIBLE TEMPERATURE.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:USE SUPPLIED AIR RESPIRATOR IF CARBON DIOXIDE
    LEVELS ARE ABOVE RECOMMENDED LIMITS OR DURING EMERGENCY RESPONSE TO
    RELEASE OF THIS PRODUCT. IF APPROPRIATE, INSTALL AUTOMATIC
    MONITORING EQUIPMENT TO DET ECT THE LEVELS OF CARBON DIOXIDE AND
    OXYGEN.
Ventilation:PROVIDE ADEQUATE NATURAL, LOCAL EXHAUST, AND/OR
    MECHANICAL(GENERAL) VENTILATION AS NEEDED TO PREVENT ACCUMULATION
    ABOVE THE TWA.
Protective Gloves:WEAR LOW TEMPERATURE PROTECTIVE GLOVES.
Eye Protection:SAFETY GLASSES, GOGGLES, OR FACE-SHIELDS. FACE-SHIELD
    MUST BE WORN FOR LIQUID.
Other Protective Equipment:USE BODY PROTECTION APPROPRIATE FOR TASK.
Work Hygienic Practices:NORMAL WORK HYGENIC PRACTICES.
