Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:TARGET ORGANS:LUNGS AND CENTRAL
    NERVOUS SYSTEM. ACUTE- SIMPLE ASPHYXIANT. MAY CAUSE ANESTHETIC
    EFFECTS, DIZZINESS, DEEP BREATHING, NAUSEA & UNCONCIOUSNESS.
    INHALATION OF ACETONE SOLVENT MAY CAUSE DIZZ INESS, RESPIRATORY
    IRRITATION. ORAL:INGESTION IS UNLIKELY. EYES/SKIN:NONE. ACETONE
    CAUSES IRRITATION. CHRONIC- UNKNOWN.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:IRRITATION OF RESPIRATORY TRACT, EYES AND SKIN;
    HEADACHES, DIZZINESS, SHORTNESS OF BREATH, LOSS OF CONSCIOUSNESS,
    HEADACHE, NAUSEA, VOMITING, FATIGUE, DERMATITIS
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH A HISTORY OF
    RESPIRATORY DISORDERS MAY BE AT INCREASED RISK FROM EXPOSURE.

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

First Aid:GET MEDICAL ATTENTION IF SYMPTOMS PERSIST. INHALED:REMOVE TO
    FRESH AIR. PROVIDE OXYGEN/CPR IF NEEDED. TREAT SYMPTOMATICALLY &
    SUPPORTIVELY. KEEP VICTIM WARM & QUIET. EYES:NONE NORMALLY
    REQUIRED. CONSU LT A PHYSICIAN IF DIRECT CONTACT OCCURS.
    IMMEDIATELY FLUSH WITH LOW PRESSURE, COOL WATER FOR AT LEAST 15
    MINUTES. KEEP EYELIDS OPEN. SKIN:WASH WITH SOAP & WATER.
    INGESTION:NONE NORMALLY REQUIRED.

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

Flash Point:FLAMMABLE GAS
Autoignition Temp:Autoignition Temp Text:565F
Lower Limits:2.2
Upper Limits:80 - 85
Extinguishing Media:DRY CHEMICAL, CARBON DIOXIDE. COOL CYLINDERS WITH
    WATER SPRAY.
Fire Fighting Procedures:ONLY SAFE WAY TO EXTINGUISH FIRE IS TO STOP
    THE FLOW OF GAS. IF FLOW CANNOT BE STOPPED, LET FIRE BURN ITSELF
    OUT WHILE COOLING WITH WATER FOG. STAY UPWIND.
Unusual Fire/Explosion Hazard:EXTREMELY FLAMMABLE AND EXPLOSIVE. IT MAY
    DECOMPOSE VIOLENTLY IN ITS FREE STATE UNDER PRESSURE IN EXCESS OF
    15 PSIG. IT BURNS WITH AN INTENSELY HOT FLAME.

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

Spill Release Procedures:WEAR PROTECTIVE EQUIPMENTS. VENTILATE AREA.
    REMOVE SOURCES OF IGNITION, HEAT, SPARKS. STOP LEAK IF YOU CAN DO
    IT WITHOUT RISK OR REMOVE CYLINDERS WITH SLOW LEAKS TO A REMOTE,
    OUTDOOR LOCATION. AVOID E NTERING AREA OF FLAMMABLE ATMOSPHERE.
    CALL VENDOR.
Neutralizing Agent:NOT RELEVANT

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

Handling and Storage Precautions:STORAGE OF 2500 CUBIC FEET OR LESS IS
    PERMISSIBLE WITHIN BUILDING. STORAGE IN EXCESS OF 2500 CUBIC FEET
    SHOULD BE OUTDOORS.
Other Precautions:EXTREMELY FLAMMABLE. SECURE CYLINDER IN UPRIGHT
    POSITION. STORE AWAY FROM INCOMPATIBLES AND HEAT. ACETYLENE STORED
    IN CYLINDER IS DISSOLVED IN ACETONE. INSPECT FUSE PLUGS ON TOP &
    BOTTOM OF CYLINDERS.  POST "NO SMOKING OR OPEN FLAME" SIGNS.

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

Respiratory Protection:OXYGEN-DEFICIENT ATMOSPHERES ARE IN FLAMMABLE
    RANGE. DO NOT ENTER. IT MAY IGNITE/EXPLODE. AIR PURIFYING
    RESPIRATOR WILL NOT FUNCTION. POSITIVE-PRESSURE AIR LINE WITH MASK
    OR NIOSH-APPROVED SELF-CONTAI NED BREATHING APPARATUS IN
    EMERGENCIES.
Ventilation:MECHANICAL (GENERAL AND/OR LOCAL EXHAUST, EXPLOSION-PROOF)
    VENTILATION TO MAINTAIN EXPOSURE BELOW PLV.
Protective Gloves:WELDER'S GLOVES; PVC OR RUBBER IN LAB
Eye Protection:SAFETY GLASSES OR WELDER GOGGLES
Other Protective Equipment:LEATHER SLEEVES, LEATHER APRON AND OTHER
    STANDARD PROTECTIVE EQUIPMENT FOR CUTTING AND WELDING, SAFETY SHOES
Work Hygienic Practices:OBSERVE GOOD PERSONAL HYGIENE PRACTICES AND
    RECOMMENDED PROCEDURES.
Supplemental Safety and Health
USE ONLY IN WELL VENTILATED AREAS. HANDLE CYLINDERS WITH CARE. OPEN AND
    CLOSE VALVES SLOWLY.
