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

LD50 LC50 Mixture:NO DATA PROVIDED BY MANUFACTURER
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA: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 UNCONSCIOUSNE S.

    LUNGS CAUSE UNCONSCIOUS NES.
Medical Cond Aggravated by Exposure:NO DATA PROVIDED BY MANUFACTURER

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

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
    OVEREXPOSURE TO ACETYLENE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH
    SELF-CONTAINED BREATHING APPARATUS AND BE COGNIZANT OF EXTREME FIRE
    AND EXPLOS ION HAZARD. INHALATION: CONSCIOUS PERSONS SHOULD BE
    ASSISTED TO AN UNCONTAMINATED AREA AND INHALE FRESH AIR. QUICK
    REMOVAL FROM THE CONTAMINATED AREA IS MOST IMPORTANT. UNCONSCIOUS
    PERSONS SHOULD BE M OVED TO AN UNCONTAMINATED AREA, GIVEN
    MOUTH-TO-MOUTH RESUSCITATION AND SUPPLEMENTAL OXYGEN. MEDICAL
    ASSISTANCE SHOULD BE SOUGHT IMMEDIATELY.

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

Autoignition Temp:=296.1C, 565.F
Lower Limits:2.2
Upper Limits:80-85
Extinguishing Media:CARBON DIOXIDE, DRY CHEMICAL
Fire Fighting Procedures:IF POSSIBLE, STOP FLOW OF ESCAPING GAS. USE
    WATER SPRAY TO COOL SURROUNDING CONTAINERS. KEEP PERSONNEL AWAY
    SINCE HEATED OR BURNING CYLINDERS CAN RUPTURE VIOLENTLY. FLAMMABLE
    OVER AN EXTREMELY WIDE RA NGE IN AIR.
Unusual Fire/Explosion Hazard:GASEOUS ACETYLENE IS SPONTANEOUSLY
    COMPUSTIBLE IN AIR AT PRESSURES ABOVE 30 PSIA.(207 KPA).IT REQUIRES
    A VERY LOW INGNITION ENERGY SO THAT FIRES WHICH HAVE BEEN
    EXTINGUISED WITHOUT STOPPING THE FLOW O F GAS CAN EASILY REIGNITE
    WITH POSSIBLE EXPLOSIVE FORCE.

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

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
    APPROPRIATE PROTECTIVE EQUIPMENT. IF LEAK IS IN USER'S EQUIPMENT,
    BE CERTAIN TO PURGE PIPING WITH AN INERT GAS PRIOR TO ATTEMPTING
    REPAIRS. IF LEAK IS IN  CONTAINER OR CONTAINER VALVE, CONTACT THE
    CLOSEST LIQUID AIR CORPORATION LOCATION.
Neutralizing Agent:NO DATA PROVIDED BY MANUFACTURER

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

Handling and Storage Precautions:USE ONLY IN WELL-VENTILATED AREAS.
    VALVE PROTECTION CAPS MUST REMAIN IN PLACE UNLESS CONTAINER IS
    SECURED WITH VALVE OUTLET PIPED TO USE POINT. DO NOT DRAG, SLIDE OR
    ROLL CYLINDERS. USE A SUITABLE HAN D TRUCK FOR CYLINDER MOVEMENT.
    USE A PRESSURE REDUCING REGULATOR WHEN REMOVING GAS FROM THE
    CYLINDER
Other Precautions:EARTH-GROUND AND BOND ALL LINES AND EQUIPMENT
    ASSOCIATED WITH THE ACETYLENE SYSTEM. ELECTRICAL EQUIPMENT SHOULD
    BE NON-SPARKING OR EXPLOSION PROOF. COMPRESSED GAS CYLINDERS SHOULD
    NOT BE REFILLED EXCE PT BY QUALIFIED PRODUCERS OF COMPRESSED GASES.

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

Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR
    SELF-CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR
    EMERGENCY USE.
Ventilation:HOOD WITH FORCED VENTILATION. TO PREVENT ACCUMULATION ABOVE
    THE LEL.  IN ACCORDANCE WITH THE ELECTRICAL CODES.
Protective Gloves:PVC OR RUBBER IN LABORATORY; AS REQUIRED FOR CUTTING
    & WELDING.
Eye Protection:SAFETY GOGGLES OR GLASSES.
Other Protective Equipment:SAFETY SHOES, SAFETY SHOWER.
Work Hygienic Practices:NO DATA PROVIDED BY MANUFACTURER
Supplemental Safety and Health
POSSIBLE INCREASING FIRE INTENSITY AND EXPLOSION HAZARD IF CYLINDERS
    ARE SO PILED OR STACKED THAT BURNING GAS ESCAPING FROM A MELTED
    FUSE PLUG (PRESSURE RELIEF DEVICE) PLAYS ON OTHER CYLINDERS. PER SA
    MMS: THIS NSN IS FOR GAS ONLY. FILLED CYLINDER NSN:
    6830-00-144-4958. EMPTY CYLINDER: 8120-00-285-4733.

Toxicological Information:AS A NARCOTIC GAS OR INTOXICANT CAUSES
    HYPERCAPNIA. REPEATED EXPOSURES TO TOLERABLE LEVELS HAS NOT SHOWN
    DELETERIOUS EFFECTS. THE MAJOR PROPERTY IS THE EXCLUSION OF AN
    ADEQUATE SUPPLY OF OXYGEN TO THE  LUNGS.
