TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / 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. 
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. 
In case of fire: keep cylinder cool by spraying with water. 
EXPOSURE
AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN! 

Inhalation Cough. Sore throat. Dizziness. Headache. Drowsiness. Blurred vision. Nausea. Unconsciousness. 
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. See Skin. 
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 PACKAGING & LABELLING

1,3-BUTADIENE ICSC: 0017
IMPORTANT DATA
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. As a result of flow, agitation, etc., electrostatic charges can be generated. The vapours are uninhibited and may form polymers in vents or flame arresters of storage tanks, resulting in blockage of vents.

CHEMICAL DANGERS: 
The substance can under specific circumstances (exposure to air) 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: 
TLV: 2 ppm as TWA; A2 (suspected human carcinogen); (ACGIH 2004). 
MAK: Carcinogen category: 1; Germ cell mutagen group: 2; (DFG 2004).
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, resulting in leukemia. 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.
PHYSICAL PROPERTIES
Boiling point: -4℃
Melting point: -109℃
Relative density (water = 1): 0.6
Solubility in water: none (0.1 g/100 ml)
Vapour pressure, kPa at 20℃: 245
Relative vapour density (air = 1): 1.9
Flash point: -76℃
Auto-ignition temperature: 414℃
Explosive limits, vol% in air: 1.1-16.3
Octanol/water partition coefficient as log Pow: 1.99
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. 
Card has been partly updated in October 2004 and April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
