Hazards

Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Effects of Overexposure:INHALATION: LOW CONCENTRATIONS CAUSE SYMPTOMS
SIMILAR TO THAT OF BEING INTOXICATED. HIGHER
CONCENTRATIONS SO AS TO EXCLUDE AN ADEQUATE SUPPLY OF OXYGENTO THE
LUNGS CAUSE UNCONSCIOUSNESS.

First Aid

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY. INHALATION:
MOVE/ASSIST PERSON TO UNCON- TAMINATED AREA AND BREATH FRESH AIR.
IF NOT BREATHING GIVE CPR AND SUPPLEMENTAL OXYGEN. MEDICAL
ASSISTANCE SHOULD BE SOU GHT IMMEDIATELY.

Fire Fighting

Flash Point:GAS
Autoignition Temp:Autoignition Temp Text:*BELOW
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 CONTIANERS.KEEP PEOPLE AWAY
SINCE HEATED/BURNING CYLINDERS CAN RUPTURE VIOLENTLY
Unusual Fire/Explosion Hazard:GASEOUS ACETYLENE REQUIRES LOW IGNITION
ENERGY SO EXTINGUISHED FIRES W/O STOPPEDGAS FLOW CAN EASILY
REIGNITE WITH POSSIBLE EXPLOSIVE FORCE. DOES NOT DISSIPATE.

Accidental Release

Spill Release Procedures:EVACUATE AREA. USE APPROPRIATE PROTECTIVE
EQUIP. IF LEAK IS IN USER'S EQUIP, BE CERTAIN TO PURGE PIPING
WITH INERT GAS PRIOR TO ATTEMPTING REPAIRS.IF LEAK IS IN CONTAINER
