Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Reactivity
The substance may polymerize. Reacts violently with oxygen and oxidants. This generates fire and explosion hazard.
Chemical stability
Stable
Possibility of hazardous reactions
Highly flammable ... Dangerous fire ... risk.The gas is heavier than air and may travel along the ground; distant ignition possible.The unsaturated aliphatic hydrocarbons, such as 1-BUTENE, are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. In the presence of various catalysts (such as acids) or initiators, compounds in this class can undergo very exothermic addition polymerization reactions. May react with oxidizing materials. Aluminum borohydride reacts with alkenes and in the presence of oxygen, combustion is initiated even in the absence of moisture.

Persistence and degradability
Cell free extracts and suspensions of microorganisms isolated from soil or water and raised on ethylene were found to epoxidize 1-butene to butene-1,2-epoxide(1,2). Methanotrophic bacteria isolated from soil and water were found to epoxidize 1-butene(3). Pure cultures of Pseudomonas oleovorans grown on octane oxidized 1-butene to 1-butene-3-ol(4). Bacteria isolated from soil and water and raised on propane were found to epoxidize 1-butene(5). Alkenes can be utilized by a wide range of microorganisms and are catabolized via several routes(6). These include the oxidation of a terminal methyl group leaving the double bond intact and resulting in unsaturated alcohol, aldehyde and fatty acid or oxidation of the double bond resulting in the formation of epoxide, diol compounds and possibly hydroxyacids(6).
Bioaccumulative potential
An estimated BCF of 14 was calculated for 1-butene(SRC), using a log Kow of 2.40(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-butene can be estimated to be 44(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-butene is expected to have very high mobility in soil.
Other adverse effects
no data available
Disposal methods
ProductThe 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.
