CAS:74-86-2
RTECS #:AO9600000
> Wt:99.
Other REC Limits:NONE RECOMMENDED
ACGIH TLV:ASPHYXIANT; 9394

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

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: RESPIRATORY SYSTEM.
    ACUTE- ACETYLENE IS A SIMPLE ASPHYXIANT. IT SHOULD BE NOTED THAT
    BEFORE SUFFOCATION COULD OCCUR, THE LOWER FLAMMABILITY LIMIT OF
    ACETYLENE IN AIR WOULD BE EXPECTED;  POSSIBLY CAUSING BOTH AN
    OXYGEN DEFICIENT AND AN EXPLOSIVE ATMOSPHERE. EXPOSURE TO MODERATE
    CONCENTRATIONS MAY CAUSE DIZZINESS, HEADACHE, AND UNCONSCIOUSNESS.
    EYE CONTACT: NONE. SKIN CONTACT: NONE. IN GESTION: THIS PRODUCT IS
    A GAS. CANNOT BE SWALLOWED OR CONTACTED. CHRONIC- ACETYLENE IS A
    NON-TOXIC GAS THAT HAS NO CHRONIC HARMFUL EFFECTS EVEN IN HIGH
    CONCENTRATIONS. ACETYLENE HAS BEEN USED AS AN A NESTHETIC.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:ASPHYXIANAT, IRRITANT, ANESTHETIC. HEADACHE,
    DIZZINESS, SHORTNESS OF BREATH, LOSS OF CONSCIOUSNESS
Medical Cond Aggravated by Exposure:NONE

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

First Aid:INHALATION: REMOVE TO FRESH AIR. IF NOT BREATHING, ADMINISTER
    ARTIFICIAL RESPIRATION. IF BREATHING IS DIFFICULT, AMINISTER
    OXYGEN. OBTAIN PROMPT MEDICAL ATTENTION. EYE CONTACT: N/R. SKIN
    CONTACT: N/R.  INGESTION: N/R. NOTE TO PHYSICIAN: NONE.

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

Flash Point:GAS
Autoignition Temp:=305.C, 581.F
Lower Limits:2.5%
Upper Limits:81%
Extinguishing Media:CARBON DIXOIDE, DRY CHEMICAL, WATER. KEEP CYLINDERS
    COOL WITH WATER SPRAY.
Fire Fighting Procedures:NIOSH-APPROVED SELF-CONTAINED BREATHING
    APPARATUS MAY BE REQUIRED FOR FIRE FIGHTERS. EVACUATE ALL PERSONNEL
    FROM DANGER AREA. IF POSSIBLE, SHUT OFF FLOW OF ACETYLENE.
    EXTINGUISH FIRE ONLY IF FLOW CAN  BE STOPPED. IF A FLAME IS
    EXTINGUISHED AND ACETYLENE CONTINUE TO ESCAPE, AN EXPLOSIVE
    RE-IGNITION COULD OCCUR.
Unusual Fire/Explosion Hazard:EXCESSIVE HEAT OR FIRE WILL CAUSE
    PRESSURE RELIEF DEVICE TO MELT ALLOWING ACETYLENE TO ESCAPE.
    CYLINDERS MAY RUPTURE VIOLENTLY IF SIDEWALLS ARE EXPOSED TO DIRECT
    FLAME.

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

Spill Release Procedures:EVACUATE IMMEDIATE AREA. ELIMINATE ANY
    POSSIBLE SOURCES OF IGNITION, AND PROVIDE MAXIMUM EXPLOSION-PROOF
    VENTILATION. SHUT OFF SOURCE OF ACETYLENE, IF POSSIBLE. ISOLATE ANY
    LEAKING CYLINDER. IF LEAKIN G FROM CYLINDER, VALVE, OR PRESSURE
    RELIEF DEVICE, CONTACT YOUR SUPPLIER.
Neutralizing Agent:NONE

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

Handling and Storage Precautions:STORE AND USE WITH ADEQUATE
    VENTILATION. CYLINDERS SHOULD BE SEPARATED FROM OXYGEN AND OTHER
    OXIDIZERS BY A MINIMUM DISTANCE OF 20 FT. OR BY A BARRICADE OF
    NON-COMBUSTIBLE MATERIAL AT LEAST 5 FT. HIGH  HAVING A FIRE
    RESISTANCE RATING OF AT LEAST 1/2 HOUR.
Other Precautions:STORAGE IN EXCESS OF 2,500 CU.FT. IS PROHIBITED IN
    BUILDINGS WITH OTHER OCCUPANCIES. DO NOT ALLOW STORAGE TEMPERATURES
    EXCEEDS 125F (52C). PROTECT CYLINDERS FROM PHYSICAL DAMAGE. DO NOT
    DRAG, SLIDE OR  DROP. USE A SUITABLE HAND TRUCK. ELECTRICAL
    EQUIPMENT SHOULD BE NON-SPARKING OR EXPLOSION-PROOF.

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

Respiratory Protection:OXYGEN-DEFICIENT ATMOSPHERS ARE IN THE FLAMMABLE
    RANGE. DO NOT ENTER. AIR PRUIFYING RESPIRATORS WILL NOT FUNCTION.
    USE NIOSH-APPROVED AIR-SUPPLIED RESPIRATORS IN OXYGEN-DEFICIENT
    ATMOSPHERES.
Ventilation:MECHANICAL (GENERAL AND/OR LOCAL EXHAUST, EXPLOSION-PROOF)
    VENTILATION TO ENSURE ACETYLENE DOES NOT REACH ITS LOWER FLAMMABLE
    LIMIT OF 2.5%.
Protective Gloves:WORK GLOVES WHEN HANDLING CYLINDERS
Eye Protection:SAFETY GLASSES WHEN HANDLING CYLINDERS
Other Protective Equipment:SAFETY SHOES RECOMMENDED WHEN HANDLING
    CYLINDERS
Work Hygienic Practices:OBSERVE GOOD INDUSTRIAL HYGIENE PRACTICES AND
    RECOMMENDED PROCEDURES. WASH AFTER HANDLING AND BEFORE EATING,
    DRINKING OR SMOKING.
