Hazards

Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic: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
Explanation of Carcinogenicity:ACETYLENE IS DEFINED AS A SIMPLE
ASPHYXIANT.
Effects of Overexposure:INHALATION: LOW CONCENTRATION (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 UNCONSCIOUSNES S.

First Aid

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE TO ACETYLENE.RESCUE PERSONNEL SHOULD BE EQUIPPED
W/SELFCONTAINED BREATHING APPARATUS & BE COGNIZANT OF EXTREME
FIRE & EXPLOSION HA ZARD. INHALATION: CONSCIOUS PERSONSSHOULD BE
ASSISTED TO AN UNCONTAMINATED AREA & INHALE FRESH AIR. QUICK
REMOVAL FROM CONTAMINATED AREA IS MOST IMPORTANT.UNCONSCIOUS
PERSONS GIVE RESUSCITATION.

Fire Fighting

Flash Point:GAS
Autoignition Temp:Autoignition Temp Text:****
Lower Limits:80-85
Upper Limits:2.2
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/BURNING CYLINDERS CAN RUPTURE.
Unusual Fire/Explosion Hazard:IT REQUIRES A VERY LOW IGNITION ENERGY SO
THAT FIRES WHICH HAVE BEEN EXTINGUISH W/O STOPPING FLOW OF GAS CAN
EASILY REIGNITE W/POSSIBLE EXPLOSIVE FORCE.

Accidental Release

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
APPROPRIATE PROTECTIVE EQUIP. IF LEAK IS IN USER'SEQUIP.,BE
CERTAIN TO PURGE PIPING W/INERT GAS PRIOR TO ATTEMPTING
REPAIRS.IF LEAK IS IN CONTAINR OR CONTAINR VALVE CONTACT CLOSEST
LIQUID AIR CORP.

ASSOCIATED W/ACETYLENE SYSTE M.

Exposure Controls

Respiratory Protection:POSITIVE PRESSURE AIR LINE W/MASK OR
SELFCONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR
EMERGENCY USE.
