Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACUTE: CARBON DIOXIDE IS AN ASPHYXIANT
    AND POWERFUL CEREBRAL VASODILATOR. IF CONCENTRATION  REACHES 10% OR
    MORE, SUFFOCATION CAN OCCUR. INHALING HIGH CONCENTRATIONS CAN LEAD
    TO COMA OR DEATH. AT LOW C ONCENTRATIONS, INHALATION OF CARBON
    DIOXIDE CAN CAUSE  NAUSEA, DIZZINESS, VISUAL DISTURBANCES, SHAKING,
    HEADACHE, MENTAL CONFUSION, SWEATING, INCREASED HEARTBEAT, AND
    ELEVATED BLOOD PRESSURE AND RESPI RATORY RATE. HIGH CONCENTRATIONS
    OF CO2 IN AIR MAY CAUSE EYE IRRITATION OR DAMAGE. CHRONIC:
    REVERSIBLE EFFECTS ON  ACID-BASE BALANCE IN BLOOD, BLOOD PRESS, AND
    CIRCULATORY SYSTEM MAY OCCUR AFTER PROLO NGED EXPOSURE TO ELEVATED
    CO2 LEVELS.
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 WITH OUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. AT
    A MINIMUM, SELF-CONTAINED BREATHING APPARATUS PERSONAL PROTECTIVE
    EQUIPM ENT 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, PLACEFROSTBITTEN 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 BEIN 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:STORE CYLINDERS UPRIGHT FIRMLY SECURED
    IN DRY,  WELL-VENTILATED AREA AWAY FROM HEAT, DIRECT SUNLIGHT,
    HEAVY TRAFFIC AREAS AND EMERGENCY EXITS. AVOID PHYSICAL DAMAGE.
    ISOLATE FROM INCOMPATIBLE CHEMICAL S. DO NOT ALLOW AREA WHERE
    CYLINDERS ARE STORED TO EXCEED 125F. KEEP CYLINDERS AWAY FROM
    MOISTURE.
Other Precautions:USE ONLY CONTAINERS AND EQUIPMENT ( PIPES, VALVES,
    FITTING, ETC) DESIGNED FOR USE WITH CARBONDIOXIDE. AVOID GETTING
    CARBON DIOXIDE IN YOU. DO NOT EAT OR DRINK WHILE HANDLING
    CHEMICALS. BE AWARE OF SIG NS OF DIZZINESS, FATIGUE, OR ANY
    EXPOSURE TO FATAL CONCENTRATIONS OF CARBON DIOXIDE.

=============  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 MECHANICAL-RESISTANT GLOVES FOR HANDLING
    CYLINDERS.
Eye Protection:SAFETY GLASSES, GOGGLES, OR FACE-SHIELDS AS NEEDED FOR
    EYE PROTECTION.
Other Protective Equipment:USE BODY PROTECTION APPROPRIATE FOR TASK.
