SECTION 4: First aid measures
Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
no data available
Indication of immediate medical attention and special treatment needed, if necessary
If contact of the liquid form of 1,3-butadiene with the skin occurs, frostbite may develop. If frostbite develops, cover the frostbitten part with a warm hand or woolen material. If the fingers or hand are frostbitten, have the victim hold his hand in his armpit next to his body. Then place the frostbitten part in warm water, about 42 deg C (108 deg F). If warm water is not available, or is impractical to use, wrap the affected part gently in blankets. Let the circulation re-establish itself naturally. Encourage the victim to exercise the affected part while it is being warmed.

Incompatible materials
1,2-Butadiene reacts rapidly with ozone under standard laboratory conditions (-78 deg C in methanol) to produce carbon monoxide, acetaldehyde, some peroxidic compounds, and acetic acid.
Hazardous decomposition products
1,2-Butadiene decomposes to complex product mixtures when irradiated at short (147 nm) and intermediate (220-260 nm) wavelength light. Photodecomposition products for the 220-260 nm include: methylacetylene, 1-butyne, and allene. Similar products were found after photolysis 147 nm along with an unidentified polymer.

Persistence and degradability
No biodegradation data regarding 1,2-butadiene were located, however data on its structural isomer, 1,3-butadiene are available(1-4). Laboratory studies employing pure bacterial cultures isolated from lake and soil samples were shown to degrade 1,3-butadiene to 1,2-epoxybutene, however it is not clear what the rate of degradation is under environmental conditions(1-3). The biodegradation half-life of 1,3-butadiene in aerobic waters has been reported as 7 days and the half-life in anaerobic waters was reported as 28 days(4). These data suggest that 1,2-butadiene will also undergo biodegradation under similar conditions(SRC).
Bioaccumulative potential
An estimated BCF of 8 was calculated for 1,2-butadiene(SRC), using an estimated log Kow of 2.06(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low (SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1,2-butadiene can be estimated to be 24(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1,2-butadiene is expected to have very high mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
