=============  Composition/Information on Ingredients  =============

Ingred Name:ACETYLENE
CAS:74-86-2
RTECS #:AO9600000
Other REC Limits:NONE SPECIFIED
ACGIH TLV:ASPHYXIANT; 9192

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

Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Health Hazards Acute and Chronic:INHALATION: LOW CONCENTRATIONS (10-20%
    IN AIR) CAUSE SYMPTOMS SIMILAR TO THAT OF BEING INTOXICATED. HIGHER
    CONCENTRATIONS SO AS TO EXCLUDE AN ADEQUATE SUPPLY OF OXYGEN TO THE
    LUNGS CAUSE UNCONSICOUSNE SS. AS A NARCOTIC GAS OR INTOXICANT
    CAUSES HYPERCAPNIA (AN EXCESSIVE AMOUNT OF CARBON DIOXIDE IN THE
    BLOOD). REPEATED *
Effects of Overexposure:*EXPOSURES TO TOLERABLE LEVELS HAS NOT SHOWN
    DELETERIOUS EFFECTS. THE MAJOR PROPERTY IS THE EXCLUSION OF AN
    ADEQUATE SUPPLY OF OXYGEN TO THE LUNGS.
Medical Cond Aggravated by Exposure:ACETYLENE IS DEFINED AS A SIMPLE
    ASPHYXIANT. OXYGEN LEVELS SHOULD BE MAINTAINED AT GREATER THAN 18
    MOLAR PERCENT AT NORMAL ATMOSPHERIC PRESSURE WHICH IS EQUIVALENT TO
    A PARTIAL PRESSURE OF 135 MM HG.

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

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
    OVEREXPOSURE TO ACETYLENE. INHALE: CONSCIOUS PERSONS SHOULD BE
    ASSISTED TO AN UNCONTAMINATED AREA AND INHALE FRESH AIR. QUICK
    REMOVAL FROM THE CON TAMINATED AREA IS MOST IMPORTANT. UNCONSCIOUS
    PERSONS SHOULD BE MOVED TO AN UNCONTAMINATED AREA, GIVEN ARTIFICIAL
    RESPIRATION AND SUPPLEMENTAL OXYGEN. MEDICAL ATTENTION SHOULD BE
    SOUGHT IMMEDIATELY.

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

Flash Point:GAS
Autoignition Temp:Autoignition Temp Text:565F
Lower Limits:2.2
Upper Limits:80-85*
Extinguishing Media:CO2, DRY CHEMICAL. *PURE ACETYLENE IGNITES BY
    DECOMPN ABOVE 30 PSIA (207 KPA):UEL IS 100%IF SUFFT INTENSE IGNITE
    SOURCE.
Fire Fighting Procedures:IF POSS, STOP FLOW OF ESCAPING GAS. USE WATER
    SPRAY TO COOL SURROUNDING CONTAINERS. KEEP PERSONNEL AWAY SINCE
    HEATED OR BURNING CYLINDERS CAN RUPTURE VIOLENTLY.
Unusual Fire/Explosion Hazard:SPONTANEOUSLY COMBUSTIBLE @ PRESSURES
    ABOVE 30 PSIA. A VERY LOW IGNITION ENERGY NEEDED TO REIGNITE
    EXTINGUISHED FIRES. ACETYLENE DOES NOT DISSIPATE READILY.

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

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
    APPROPRIATE PROTECTIVE EQUIPMENT. LEAK IN EQUIP: PURGE PIPING WITH
    AN INERT GAS PRIOR TO REPAIR.IF LEAK IS IN CONTAINER/CONTAINER
    VALVE, CONTACT THE CLOS EST AIRCO LOCATION OR CALL CHEMTREC:
    800-424-9300.

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

Handling and Storage Precautions:PROTECT FROM PHYSICAL DAMAGE. STORE IN
    COOL, DRY, WELL-VENTILATED AREA AWAY FROM HEAVILY TRAFFICKED AREAS
    AND EMERGENCY EXITS. NO TEMP ABOVE 130F. *
Other Precautions:*CYLIN STORED UPRIGHT & FIRMLY SECURED TO PREVENT
    FALLING/BEING KNOCKED OVER. FULL & EMPTY CYLIN TO BE SEGREGATED.
    ROTATE STOCK. USE IN WELL-VENTILATED AREA. POST "NO SMOKING/OPEN
    FLAMES" SIGN, VALVE  PROTECT CAP TO REMAIN IN PLACE UNLESS **

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

Respiratory Protection:POSITIVE PRESSURE AIRLINE WITH MASK OR
    SELF-CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR
    EMERGENCY USE.
Ventilation:HOOD W/FORCED VENTILN. PREVENT ACCUMULN ABOVE LEL. ELEC
    EQUIP TO BE NON-SPARK/EXPLOSIVE PROOF. GROUND/BOND LINES, EQUIP.
Protective Gloves:LAB:PVC/RUBBER.WELDING/CUTTING:AS NEEDED
Eye Protection:SAFETY GOGGLES OR GLASSES.
Other Protective Equipment:SAFETY SHOES.
Work Hygienic Practices:NO SOURCES OF IGNITION IN STORAGE AREA. DO NOT
    ALLOW FREE GAS TO EXCEED 30 PSIA. PROTECT FROM SUDDEN SHOCK & HEAT
    SOURCE
Supplemental Safety and Health
**CNTNR IS SECURED W/VALVE OUTLET PIPED TO USE POINT. DO NOT
    DRAG,SLIDE,ROLL CYLINDERS. USE PROPER HAND TRUCK FOR CYLIN
    MOVEMENT. USE PRESSURE REDUCING REGULATOR FOR CONNECTING CYLIN TO
    LOWER PRESSURE  (3,000 PSIG) PIPING/SYSTEMS. DO NOT HEAT CYLIN TO
    INCREASE DISCHARGE RATE. USE CHECK VALVE/TRAP IN DISCHARGE LINE.
