=====================  Hazards Identification  =====================

Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:PRODUCT IS UNDER PRESSURE. DO NOT
    PUNCTURE OR INCINERATE. AVOID EXPOSURE TO TEMPERATURES ABOVE 120F
    OR OPEN FLAME. EXCESSIVE INHALATION OF VAPORS MAY BE FATAL. VAPORS
    REDUCE AVAILABLE OXYGEN IN AIR. R EDUCED OXYGEN LEVELS TO 12-14%
    PRODUCE SYMPTOMS OF ASPHYXIATION I.E. DROWSINESS, LOSS OF
    COORIDINATION, INCREASED PULSE RATE, NARCOSIS, CARDIAC
    SENSITIZATION AND DEEPER RESPIRATION. MATERIAL CAN INDUC E CARDIAC
    SENSITIZATION TO EPINEPHRINE AND CARDIAC ARRHYTHMIA. SKIN IRRITANT.
    DIRECT EXPOSURE OF SKIN TO LIQUID MAY CAUSE FROSTBITE. EYE
    IRRITANT.
Explanation of Carcinogenicity:NOT LISTED
Effects of Overexposure:OVEREXPOSURE WILL PRODUCE THE SYMPTOMS OF
    REDUCED OXYGEN: ASPHYXIATION, DROWSINESS, LOSS OF COORDINATION,
    INCREASED PULSE RATE, NARCOSIS, CARDIAC SENSITIZATION AND DEEPER
    RESPIRATION.
Medical Cond Aggravated by Exposure:ANEMIA, ASTHMA, DERMAL SENSITIVITY
    AND LOW BLOOD PRESSURE.

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

First Aid:EYE CONTACT: FLUSH WITH WATER FOR 15 MINUTES, INCLUDING UNDER
    EYELIDS. GET MEDICAL HELP. SKIN CONTACT: FLUSH WITH WATER. TREAT
    FOR FROSTBITE IF NECESSARY BY BATHING AREA WITH LUKEWARM WATER. GET
    MEDIC AL ATTENTION. INHALATION: REMOVE TO FRESH AIR. KEEP AT REST.
    RESTORE AND/OR SUPPORT BREATHING AS NEEDED. GET PROMPT MEDICAL
    ATTENTION. INGESTION: INGESTION IS NOT CONSIDERED A POTENTIAL ROUTE
    OF EXPOS URE.

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

Flash Point Method:TCC
Autoignition Temp:Autoignition Temp Text:NA
Lower Limits:NA
Upper Limits:NA
Extinguishing Media:CARBON DIOXIDE, DRY CHEMCIAL OR FOAM. WATER MAY BE
    USED TO COOL CONTAINERS EXPOSED TO THE FIRE TO REDUCE PRESSURE
    BUILDUP.
Unusual Fire/Explosion Hazard:CYLINDERS ARE UNDER PRESSURE AND MAY
    RUPTURE UNDER FIRE CONDITIONS. DECOMPOSITION MAY PRODUCE
    HYDROCHLORIC AND HYDROFLUORIC ACID. EXPOSURE TO HEAT OR PROLONGED
    EXPOSURE TO SUN MAY CAUSE BURSTING.

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

Spill Release Procedures:VENTILATE AREA, ESPECIALLY LOW PLACES WHERE
    HEAVY VAPORS MAY COLLECT. REMOVE OPEN FLAMES. ISOLATE HAZARD UNTIL
    ALL GAS HAS DISPERSED. WATER SPRAY MAY BE USED TO REDUCE VAPORS.

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

Handling and Storage Precautions:STORE IN A CLEAN, COOL, VENTILATED
    AREA AWAY FROM SOURCES OF IGNITION AND OXIDIZING AGENTS. MAINTAIN
    TEMPERATURE AT LESS THAN 120F. STORE AS A LEVEL 1 AEROSOL (NFPA
    30B). OVER HEATING, PRESSURIZING, O R RUSTING CAN CAUSE CAN TO
    BURST RESULTING IN SERIOUS PERSONAL INJURY.
Other Precautions:EMPTY CONTAINERS RETAIN RESIDUE; FOLLOW ALL LABEL
    WARNINGS EVEN AFTER CONTAINER IS EMPTY. DISPOSE OF EMPTY CONTAINER
    ACCORDING TO REGULATIONS. DO NOT REUSE THE CONTAINER.

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

Respiratory Protection:UNDER NORMAL USE OF THIS PRODUCT NO RESPIRATORY
    PROTECTION IS RQUIRED. SELF- CONTAINED BREATHING APPARATUS IS
    REQUIRED IF A LARGE RELEASE OCCURS.
Ventilation:NORMAL VENTILATION FOR STANDARD PRODEDURES IS GENERALLY
    ADEQUATE. LOCAL EXHAUST SHOULD BE USED WHEN LARGE AMOUNTS ARE
    RELEASED.
Protective Gloves:LINED NITRILE OR NATURAL RUBBER GLOVES.
Eye Protection:CHEMICAL SPLASH GOGGLES SHOULD BE WORN WHEN HANDLING
    LIQUID.
Work Hygienic Practices:AVOID INHALATION OF VAPORS AND REPEATED OR
    PROLONGED CONTACT OF LIQUID WITH SKIN OR CLOTHING. DO NOT TAKE
    INTERNALLY.
Supplemental Safety and Health
MECHANICAL VENTILATION SHOULD BE USED IN LOW PLACES. *PRODUCT NAME: PC
