*  Exposure Controls/Personal Protection  *
Respiratory Protection:OXYGEN-DEFICIENT ATMOSPHERES ARE IN THE
    FLAMMABLE RANDE.  DO NOT ENTER!    RESPIRATORS WILL NOT
    FUNCTION.
Ventilation:NATURAL OR MECHANICAL WHERE GAS IS PRESENT.
Other Protective Equipment:LEATHER SLEEVES, LEATHER APRON AND OTHER
    STANDARD PROTECTIVEEQUIPMENT FOR CUTTING AND WELDING.
Supplemental Safety and Health
MECHANICAL VENTILATION FOR ENCLOSED STORAGE AREAS MUST MEET NATIONAL
    ELECTRICAL CODE REQUIREMENTS FOR CLASS 1, GROUP A. AVOID HAZARDOUS
    MIXTURES AND SOURCES OF IGNITION.FORMATION OF EXPLOSIVE COPPER A
    CETYLIDES CAN BE AVOIDED BY USING COPPERALLOYS PROVED SUCCESSFUL
    THROUGH USE IN INDUSTRY.
*  Product Identification  *
Product ID:ACETYLENE, ETHYNE, ETHINE
*  Composition/Information on Ingredients  *
Ingred Name:ACETYLENE, ETHYNE, ETHINE
*  Hazards Identification  *
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NOOSHA:NO
Health Hazards Acute and Chronic:DO NOT ENTER AREAS WITHIN THE
    FLAMMABLE RANGE DUE TO THE IMMEDIATE FIRE AND EXPLHAZARD. 
    ACETYLENE IS A SIMPLE ASPHYXIANT, IRRITANT, AND ANESTHETIC.
Effects of Overexposure:SYMPTOMS SUCH AS HEADACHES, DIZZINESS,
    SHORTNESS OF BREATH, & LOSS OF CONSCIOUS-NESS MAY OCCUR IF THE GAS
    IS PRESENT IN QUANTITIES SUFFICIENT TO DILUTE THE OXY CONCENTRATION
    IN AIR. SYMPTOMS OF ANOXIAOCCUR ONLY WHEN THE GAS
    CONCENTRATIONSARE WITHIN THE FLAMMABLE RANGE AND THE MIXTURE HAS
    NOT IGNITED.
Medical Cond Aggravated by Exposure:ACETYLENE IS A SIMPLE ASPHYXIANT,
    FOR .5 - 1 HR. THERE IS NO EXPERIMENTAL EVIDENCE  OF CHRONIC
    HARMFUL EFFECTS.
*  First Aid Measures  *
First Aid:FIRST DEGREE & MINOR SECOND DEGREE THERMAL BURNS FROM FIRES
    DEGREE BURNS SHOULD BE COVERED IN THECLEANEST MATERIAL AVAIL.SEEK
    IMMED. PHYS ICIAN AID. PERSONS SUFFERING FROM LACKOF OXY SHOULD BE
    MOVED TO NORMAL ATMOS. AREA. CPR SHOULD BE GIVEN IF THE VICTIM IS
    NOT BREATHING.
*  Fire Fighting Measures  *
Flash Point Method:CC
Upper Limits:2.5%
Extinguishing Media:CARBON DIOXIDE, DRY CHEMICAL, HALON        
Fire Fighting Procedures:STOP GAS FLOW.  USE WATER SPRAY TO KEEP
    CYLINDERS OR OTHER CONTAINERS COOL. KEEPALL CLEAR SINCE CONTAINERS
    CAN RUPTURE VIOLENTLY. SEE CGA SAFETY BULLETIN SB-4.
Unusual Fire/Explosion Hazard:ACETYLENE IS EXTREMELY FLAMMABLE &
    EXPLOSIVE.IT BURNS WITH INTENSELY HOT FLAME. WIDE FLAMMABLE LIMITS.
     IGNITES EASILY.  STAYS IN POCKETS RATHER THAN DISSIPATE.
*  Accidental Release Measures  *
Spill Release Procedures:VENTILATE AREA TO PREVENT FLAMMABLE MIXTURE
    FROM  FORMING.REMOVE SOURCES OF IGNITION, HEAT, SPARKS, ETC. AVOID
    ENTERING AREA OF FLAMMABLE ATMOSPHERE. CAREFULLY REMOVE CYLINDERS
    WITH SLOW LEAKS TO A RE MOTE OUTDOOR AREA.CONTACT AIR PROCUCTS FOR
    ASSIST.
*Handling and Storage  *
Handling and Storage Precautions:USE IN WELL VENTILATE AREA.ALWAYS KEEP
    CYL. SECURE& UPRIGHT.OPEN/CLOSE VALVES SLOWLY.SEE CGA PAMP P1KEEP
    AWAY FROM HEAT. SEGREGATE FULL/EMPTY CYLINDER
Other Precautions:AVOID HAZARDOUS MIXTURES AND SOURCES OF IGNITION. 
    COMPRESSED GAS CYL. SHOULDN'TBE REFILLED EXCEPT BY QUALIFIED
    PRODUCERS OF COMPRESSED GAS. AVOID EXSPOSURE TO AREAS WHERE SALT OR
    OTHER CORROSIVE CHEM ICALS ARE PRESENT.
*  Physical/Chemical Properties  *
Vapor Pres:*SEE BELOW
Vapor Density:*SEE BELOW
Solubility in Water:*SEE BELOW
Appearance and Odor:PURE ACETYLENE IS COLORLESS & ODORLESS.  IMPURITIES
    GENERATE GARLIC-LIKE ODOR.
*  Stability and Reactivity Data  *
Stability Indicator/Materials to Avoid:NO
OXYDIZERS SUCH AS OXYGEN & HALOGENS.FORMS EXPLOSIVE COMPOUNDWITH
    COPPER,BRASS,COPPER SALTS,HG&HG SALTS,K,AG&AG SALTS,HNO
Stability Condition to Avoid:NEVER UTILIZE FREE GAS OUTSIDE CYL.  NEVER
    EXPOSE TO HEAT.  AVOID MECHANICAL SHOCKS TO CONTAINERS OF
    ACETYLENE.
Hazardous Decomposition Products:ACETYLENE WILL DECOMPOSE INTO
    ELEMENTAL CARBON & HYDROGEN   UNDER THE ABOVE CONDITIONS.
*  Disposal Considerations  *
Waste Disposal Methods:DO NOT ATTEMPT TO DISPOSE OF RESIDUAL GASEOUS   
     ACETYLENE IN CYLINDERS. RETURN TO AIR PRODUCTS FORDISPOSAL.
