CAS:74-86-2
RTECS #:AO9600000
&gt; Wt:99.

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

LD50 LC50 Mixture:LD50:(ORAL) NONE REPORTED.
Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACUTE: INHALATION: ACETYLENE IS A
    SIMPLE ASPHYXIANT. IT SHOULD BE NOTED THAT BEFORE SUFFOCATION COULD
    OCCUR, THE LOWER FLAMMABILITY LIMIT OF ACETYLENE IN AIR WOULD BE
    EXCEEDED; POSSIBLY CAUSING BOTH A N OXYGEN DEFICIENT AND AN
    EXPLOSIVE ATMOSPHERE. EXPOSURE TO MODERATE CONCENTRATIONS MAY CAUSE
    DIZZINESS, HEADACHE AND UNCONSCIOUSNESS. EYE/SKIN CONTACT: NONE.
    CHRONIC: ACETYLENE IS A NON-TOXIC GAS THA T HAS NO CHRONIC HARMFUL
    EFFECTS EVEN IN HIGH CONCENTRATIONS. ACETYLENE HAS BEEN USED AS AN
    ANESTHETIC.
Explanation of Carcinogenicity:ACETYLENE IS NOT LISTED BY NTP, OSHA OR
    IARC.
Effects of Overexposure:SEE HEALTH HAZARDS.
Medical Cond Aggravated by Exposure:NONE.

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

First Aid:INHALATION: REMOVE PERSON TO FRESH AIR. IF NOT BREATHING,
    ADMINISTER ARTIFICIAL RESPIRATION. IF BREATHING IS DIFFICULT,
    ADMINISTER OXYGEN. OBTAIN PROMPT MEDICAL ATTENTION. EYES: NOT
    APPLICABLE. IMMEDI ATELY FLUSH W/POTABLE WATER FOR AT LEAST 15
    MINUTES, SEEK ASSISTANCE FROM MD . SKIN: NOT APPLICABLE. FLUSH
    W/COPIOUS AMOUNTS OF WATER. CALL MD . INGESTION: NOT APPLICABLE.

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

Autoignition Temp:=305.C, 581.F
Lower Limits:2.5%
Upper Limits:81%
Extinguishing Media:CARBON DIOXIDE, DRY CHEMICAL, WATER.
Fire Fighting Procedures:USE NIOSH APPRVD SCBA & FULL PROTECTIVE EQUIP
    . SHUT OFF SOURCE OF ACETYLENE IF POSS. EXTING FIRE ONLY IF FLOW
    CAN BE STOPPED. KEEP ADJACENT CYLS COOL BY SPRAYING LG AMTS OF
    WATER UNTIL FIRE BUR NS ITSELF OUT & CYLS ARE COOL. IF FLAME IS
    EXTINGUISHED & ACETYLENE CONTINUES TO ESCAPE, EXPLO RE-IGNITION
    COULD OCCUR.

    REACTIVITY - 3. HMIS RATINGS:HLTH - 1; FLAMMABILITY - 4; REACTIVITY
    - 3. EXCESSIVE HEAT/FIRE WILL CAUSE FUSIBLE METAL PRESS RELIEF
    DEVICE TO MELT ALLOWING ACET YLENE TO ESCAPE. CYLS MAY RUPTURE
    VIOLENTLY IF SIDEWALLS ARE EXPOS TO DIRECT FLAME IMPINGEMENT.
    ACETYLENE IS (SUPP DATA)

==================  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 FUSIBLE
    METAL PRESSURE RELIEF DEVICE, CONTACT YOUR SUPPLIER.

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

Handling and Storage Precautions:STORE & USE W/ADEQ VENT. CYLS SHOULD

    BARRICADE OF NON-COMBUST MATL AT LST 5 FT HIGH HAVING FIRE
    RESISTANCE RATING OF AT LST 1/2 HR. STO R >2,500 CU FT IS
    PROHIBITED IN BLDGS W/OTHER OCCUPANCIES. THERE SHOULD BE NO SOURCES
    OF IGNITION.
Other Precautions:CYLS SHOULD E STORED UPRIGHT W/VALVE PROT CAP IN
    PLACE & FIRMLY SECURED TO PVNT FALLING/BEING KNOCKED OVER. POST "NO
    SMOKING/OPEN FLAMES" SIGNS IN STOR/USE AREAS. ALL ELEC EQUIP SHOULD
    BE EXPLO-PROOF  IN STOR AREAS. STOR AREAS MUST MEET NEC FOR CLASS 1
    HAZ AREAS. DO NOT ALLOW STOR TEMP TO EXCEED 125F (52C). (TOX INFO)
