Medical Cond Aggravated by Exposure:INDIVIDUALS WITH A HISTORY OF
    RESPIRATORY DISORDERS MAY BE AT INCREASED RISK FROM EXPOSURE.

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

First Aid:INHALATION: IMMEDIATELY MOVE VICTIM TO FRESH AIR. IF NOT
    BREATHING, GIVE ARTIFICIAL RESPIRATION, PREFERABLY MOUTH-TO-MOUTH.

Lower Limits:2.2
Upper Limits:80-85
Extinguishing Media:USE CARBON DIOXIDE OR DRY CHEMICAL.
Fire Fighting Procedures:STOP GAS FLOW IF POSSIBLE. LET FUEL TO CONSUME
    ITSELF. USE WATER SPRAY TO COOL ADJACENT AREAS. KEEP PERSONNEL
    AWAY. CYLINDERS CAN RUPTURE VIOLENTLY.
Unusual Fire/Explosion Hazard:ACETYLENE HAS DENSITY SIMILAR TO AIR. IT
    DOES NOT READILY DISSIPATE, AND CAN EASILY REIGNITE WITH EXPLOSIVE
    FORCE.

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

Spill Release Procedures:REMOVE PERSONNEL. ELIMINATE IGNITION SOURCES.
    VENTILATE AREA. WEAR PROTECTIVE CLOTHING AND SELF-CONTAINED
    BREATHING APPARATUS. STOP LEAK IF SAFE TO DO SO.

Handling and Storage Precautions:STORE AND USE IN DRY, WELL VENTILATED
    AREAS AWAY FROM SOURCES OF HEAT OR IGNITION. STORAGE AREA SHOULD
    NOT EXCEED 130F.
Other Precautions:PROTECT CYLINDERS FROM PHYSICAL DAMAGE. DO NOT DRAG,
    SLIDE OR ROLL CYLINDERS. DO NOT ALLOW FREE GAS TO EXCEED 15 PSI. DO
    NOT HEAT CYLINDER BY ANY MEANS. STORE UPRIGHT FIRMLY SECURED. KEEP
    VALVE PROTEC TION CAPS IN PLACE.

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

Respiratory Protection:NONE NORMALLY REQUIRED. IF ACETYLENE IS PRESENT
    IN THE AIR USE POSITIVE PRESSURE AIR LINE RESPIRATOR OR
    SELF-CONTAINED BREATHING APPARATUS.
Ventilation:MECHANICAL (GENERAL) AND/OR LOCAL EXHAUST VENTILATION TO
    KEEP EXPOSURE LEVELS BELOW PEL. USE EXPLOSION-PROOF EQUIPMENT.

Supplemental Safety and Health
PURE ACETYLENE CAN IGNITE BY DECOMPOSITION ABOVE 15 PSI. POST NO
    SMOKING OR OPEN FLAMES SIGNS IN STORAGE OR USE AREA. EXPOSURE TO
    THE ACETONE COMPONENT IS UNLIKELY UNLESS CYLINDER IS LEAKING ON ITS
    SI DE. ACETONE IS PRIMARILY A CENTRAL NERVOUS SYSTEM TOXIN CAUSING
    HEADACHE, NAUSEA, DIZZINESS, VOMITING AND FATIGUE.
