SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking.
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with water spray, powder, carbon dioxide.
EXPLOSION Gas/air mixtures are explosive. 1,3-Butadiene vapours are uninhibited and may form polymers in vents or flame arresters of storage tanks, resulting in blockage of vents.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools.
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
 
EXPOSURE
AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!

INHALATION Cough. Drowsiness. Blurred vision. Nausea. Sore throat. Unconsciousness. Respiratory paralysis.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
EYES Redness. Pain. Blurred vision.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. NEVER direct water jet on liquid (extra personal protection: self-contained breathing apparatus).
Fireproof. Separated from incompatible materials: see chemical dangers. Cool.

PHYSICAL STATE; APPEARANCE:
COLOURLESS COMPRESSED LIQUEFIED GAS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The gas is heavier than air, and may travel along the ground; distant ignition possible. Liquid 1,3-butadiene floats and boils on water.

CHEMICAL DANGERS:
The substance can under specific circumstances form peroxides, initiating explosive polymerization. The substance may polymerize due to warming with fire or explosion hazard. Shock-sensitive compounds are formed with copper and its alloys (see Notes). The substance decomposes explosively on rapid heating under pressure. Reacts vigorously with oxidants and many other substances, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 10 ppm; 22 mg/m3 (as TWA, A2) (ACGIH 1992-1993).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the respiratory tract. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system , resulting in lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the bone marrow and liver. This substance is probably carcinogenic to humans. May cause heritable genetic damage in humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

ENVIRONMENTAL
DATA
NOTES
Piping material for this gas must not contain over 63% of copper. Use of alcoholic beverages enhances the harmful effect. The odour warning when the exposure limit value is exceeded is insufficient.
