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

LD50 LC50 Mixture:NONE SPECIFIED BY MANUFACTURER.
Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACETYLENE HAS BEEN USED AS AN
    ANESTHETIC, BUT IT ACTS AS A SIMPLE ASPHYXIANT IF PRESENT IN
    CONCENTRATIONS HIGH ENOUGH TO DEPRIVE LUNGS OF OXYGEN. EXPOSURE IN
    OXYGEN-DEFICIENT ATMOSPHERES CAN CAUSE DIZ ZINESS, LOSS OF
    CONSCIOUSNESS & DEATH; HOWEVER, LOWER FLAMMABLE LIMIT OF ACETYLENE
    IN AIR IS REACHED(EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT.
Effects of Overexposure:HLTH HAZ: BEFORE SUFFOCATION COULD OCCUR.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

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

First Aid:ELIM ALL POSS SOURCES OF IGNIT. INHAL: REMOVE VICTIM TO FRESH
    AIR. ASSISTED RESP & SUPPLEMENTAL OXYGEN SHOULD BE GIVEN IF THE
    VICTIM IS NOT BRTHG. RESCUE PERS MAY REQ NIOSH/MSHA APPRVD SCBA.
    EYES: FLU SH W/POTABLE WATER FOR A MINIMUN OF 15 MINS. SEEK ASIST
    FROM MD. SKIN: FLUSH W/COPIOUS AMTS OF WATER. CALL MD. INGEST: CALL
    MD IMMEDIATELY.

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

Lower Limits:2.5%
Upper Limits:80%
Extinguishing Media:DRY CHEMICAL, CARBON DIOXIDE AND WATER.
Fire Fighting Procedures:WEAR NIOSH/MSHA APPRVD SCBA & FULL PROT EQUIP.
    SHUT OFF SOURCE OF ACETYLENE, IF POSS. USE WATER SRRAY TO COOL FIRE
    EXPOS CYL. SMALL FLAME (SUPP DATA)
Unusual Fire/Explosion Hazard:EXCESS HEAT/FIRE EXCEEDING
    212F(TEMPERATURE OF BOILING WATER) WILL CAUSE FUSABLE SAFETY PLUGS
    TO RELEASE ALLOWING ACETYLENE TO ESCAPE & IF IGNIT (ING 2)

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

Spill Release Procedures:EVACUATE IMMEDIATE AREA. ELIMINATE ANY
    POSSIBLE IGNITION SOURCE & PROVIDE MAXIMUM EXPLOSION PROOF
    VENTILATION. SHUT OFF SOURCE OF ACETYLENE IF POSSIBLE. ISOLATE ANY
    LEAKING CYLINDER & CONTACT THE SUPP LIER.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

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

Handling and Storage Precautions:STORE IN A COOL, WELL-VENT PLACE AWAY
    FROM OPEN FLAMES & OTHER IGNITION SOURCES. DO NOT STORE W/IN 20
    FEET OF OXYGEN OR OTHER OXIDZIERS.
Other Precautions:STORE CYLINDERS IN AN UPRIGHT POSITION. FOLLOW
    GENERAL SAFETY PROCEDURES FOR HANDLING COMPRESSED GAS CYLINDERS
    FOUND IN CGA PAMPHLET P-1.

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

Respiratory Protection:NONE. USE NIOSH/MSHA APPROVED RESPIRATOR
    APPROPRIATE FOR EXPOSURE OF CONCERN .
Ventilation:LOCAL EXHAUST: SUFFICIENT TO KEEP AREA BELOW 2% ACETYLENE
    CONC. MECH: EXPLOS PROOF. NATURAL/MECH WHERE GAS IS PRESENT.
Protective Gloves:IMPERVIOUS GLOVES .
Eye Protection:ANSI APPRVD CHEM WORKERS GOGGLES.
Other Protective Equipment:NONE SPECIFIED BY MANUFACTURER.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
Supplemental Safety and Health
VAP DENS: 0.07314 LB/CU FT. SOLUB IN H*2O: 1.7 SCC/100CC H*2O @ 32F.
    FIRE FIGHT PROC: MAY BE PUT OUT BUT IF LGE FLAME IS PRESENT, LET IT
    BURN, PROVIDED PERS/BUILDING STRUCTURE IS NOT IN DANGER. IF FLA ME
    IS EXTING & ACETYLENE CONTINUES TO ESCAPE AN EXPLOS RE-IGNIT COULD
    OCCUR. FOLLOW INSTRUCTS FOUND IN CGA (ING 7)

==================  Physical/Chemical Properties  ==================

    THE ABSENCE OF AIR OR OXYGEN, BE MADE TO EXPLODE VIOLENTLY (I.E.
    DECOMP (ING 6)

====================  Disposal Considerations  ====================

Waste Disposal Methods:IF PRACTICAL, MOVE CYLINDER TO SAFE OUTSIDE AREA
    AWAY FROM ANY SOURCE OF IGNITION. ALLOW THE CYLINDER TO DISCHARGE
    SLOWLY INTO ATMOSPHERE & CONTACT THE SUPPLIER. DISPOSE OF IN
    ACCORDANCE WITH LOCAL, S TATE & FEDERAL REGULATIONS .
