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

LD50 LC50 Mixture:SEE TOXICOLOGICAL INFORMATION.
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACUTE: SKIN/EYES: DIRECT CONTACT WITH
    THE LIQUEFIED MATERIAL OR ESCAPING COMPRESSED GAS MAY CAUSE
    FROSTBITE INJURY. INHALATION: PURE SF6 IS OF A LOW ORDER OF
    TOXICITY, BUT MAY ACT AS AN ASPHYXIANT IF  OXYGEN IS REDUCED TO
    BELOW 16%, AS INDICATED BY PALENESS AND POSSIBLE CYANOSIS (BLUE
    SKIN). INGESTION: NOT APPLICABLE (GAS AT NORMAL CONDITIONS).
    CHRONIC: NONE KNOWN.
Explanation of Carcinogenicity:NO INGREDIENTS LISTED IN THIS SECTION.
Effects of Overexposure:SEE HEALTH HAZARDS.

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

First Aid:SKIN: WASH EXPOSED AREA EXTREMELY THOROUGHLY, BUT GENTLY IN
    CASES OF FROSTBITE-LIKE INJURY, W/SOAP & WATER. CONTACT MD IF
    IRRIT/PAIN PERSISTS. EYES: FLUSH W/COPIOUS AMOUNTS OF WARM WATER
    FOR AT LEAST  15 MINUTES. CONTACT MD IF IRRIT, PAIN, SWELLING,
    EXCESSIVE TEARING/PHOTOPHOBIA (PAINFUL SENSITIVENESS TO STRONG
    LIGHT) PERSISTS. INHAL: IMMED REMOVE TO FRESH AIR. IF BREATHING HAS
    STOPPED, GIVE ARTIFI CIAL RESPIRATION. IF BREATHING IS DIFFICULT,
    GIVE OXYGEN PROVIDED A QUALIFIED OPERATOR IS AVAILABLE. CONTACT MD.
    INGEST: NOT APPLICABLE. CALL MD IMMEDIATELY . ADVICE TO MD: NO
    SPECIFIC TREATMENT . TREAT ACCORDING TO SYMPTOMS PRESENT.

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

Extinguishing Media:IF INVOLVED IN A FIRE, USE DRY CHEMICAL OR CARBON
    DIOXIDE FOR SMALL FIRES OR WATER SPRAY, FOG, OR REGULAR FOAM FOR
    LARGE FIRES.
Fire Fighting Procedures:WEAR NIOSH APPROVED SCBA AND FULL PROTECTIVE
    EQUIPMENT . COOL CYLINDERS EXPOSED TO HEAT OF FIRE WITH FLOODING
    AMOUNTS OF WATER. APPLY WATER FROM AS FAR A DISTANCE AS POSSIBLE.
Unusual Fire/Explosion Hazard:FLAME PROPAGATION (VOLUME % IN AIR): NOT
    APPLICABLE. OSHA FLAMMABILITY CLASS: NON-COMBUSTIBLE GAS. CYLINDERS
    MAY EXPLODE IN HEAT OF FIRE. FIRE MAY PRODUCE IRRITATING OR
    POISONOUS GASES.

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

Spill Release Procedures:ALWAYS WEAR RECOMMENDED PERSONAL PROTECTIVE
    EQUIPMENT. EVACUATE UNPROTECTED PERSONNEL. STAY UPWIND. PROTECTED
    PERSONNEL MAY SHUT OFF LEAK IF WITHOUT RISK. PRODUCT WILL DISPERSE
    ITSELF. SPILLS AND RELE ASES MAY HAVE TO BE REPORTED TO FEDERAL
    AND/OR LOCAL AUTHORITIES. SEE THE REGULATORY INFORMATION SECTION
    REGARDING REPORTING REQUIREMENTS.

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

Handling and Storage Precautions:ALWAYS WEAR RECOMMENDED PERSONAL
    PROTECTIVE EQUIPMENT. AVOID BREATHING VAPORS. OBSERVE PRECAUTIONS
    ON CYLINDER LABEL. PROTECT CYLINDER FROM PHYSICAL DAMAGE. PROTECT
    CYLINDERS FROM PHYSICAL DAMAGE, HEA T, AND SUNLIGHT. STORE IN AN
    AREA OF LOW FIRE RISK.
Other Precautions:FOR ADDITIONAL INFORMATION, SEE COMPRESSED GAS
    ASSOCIATION PAMPHLET, "SAFE HANDLING OF COMPRESSED GASES IN
    CONTAINERS", 7TH EDITION, 1984.

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

Respiratory Protection:NIOSH APPROVED SELF-CONTAINED BREATHING
    APPARATUS OR NIOSH APPROVED AIR-SUPPLIED RESPIRATOR IF NEEDED. NOTE
    THAT AN ACCIDENTAL RELEASE OF SF6 MAY REDUCE THE OXYGEN CONTENT OF
    THE LOCAL ATMOSPHERE BELO W 16% (SEE HEALTH HAZARDS SECTION).
Ventilation:GENERAL MECHANICAL VENTILATION.
Protective Gloves:RUBBER GLOVES.
Eye Protection:ANSI APPROVED CHEMICAL WORKERS GOGGLES .
Other Protective Equipment:EYEWASH AND DELUGE SHOWER MEETING ANSI
