Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (ERG, 2016)|Combustible. Above 77 °C explosive vapour/air mixtures may be formed.

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2016)

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Irritating to the skin and eyes.

Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in covered containers as far as possible.

1-Dodecene was reported as a compound present in the exhaust of gasoline engine powered vehicles concns not provided(1). 1-Dodecene was qualitatively identified as a semi-volatile emission during the combustion of agricultural plastics(2).

URBAN/SUBURBAN: 1-Dodecene was qualitatively detected in air samples collected in central Paris, France, autumn of 1972(1). It was qualitatively detected in the air of Leningrad, 1976, and 5 other Russian cities(2,3). INDOOR AIR: 1-Dodecene was qualitatively identified as a volatile organic compound released from textile floor coverings(4).

practically nontoxic

1-Dodecene was emitted in unknown amounts from natural plant species chamise, whitethorn, and valley oak in the California Central Valley(1).

1-Dodecene's production and use as a chemical intermediate(1) may result in its release to the environment through various waste streams. It is also released from exhaust of gasoline powered vehicles(2) and during the combustion of plastics(3).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 5900(SRC), determined from a structure estimation method(2), indicates that 1-dodecene is expected to be immobile in soil. Volatilization of 1-dodecene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.25 atm-cu m/mole(SRC), using a fragment constant estimation method(3). 1-Dodecene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.0159 mm Hg(4). However, adsorption to soil is expected to attenuate volatilization. Pure culture studies indicate that 1-dodecene has the potential to biodegrade under aerobic conditions in soil(5-7), but the rate of biodegradation in soil is unknown(SRC).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 5900(SRC), determined from an estimation method(2), indicates that 1-dodecene is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 4.25 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.3 hr and 120 hr, respectively, but these rates are expected to be attenuated by adsorption(SRC). The half-life for volatilization from a model pond, which takes into account adsorptive processes, is 17 months(8,SRC). According to a classification scheme(5), an estimated BCF of 310(SRC), from an estimated log Kow of 6.10(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is high. Pure culture studies indicate that 1-dodecene has the potential to biodegrade under aerobic conditions in water(9-11), but the rate of biodegradation is unknown.|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-dodecene, which has a vapor pressure of 0.0159 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-dodecene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 9.961 hr(SRC), calculated from its rate constant of 39X10-12 cu cm/molecule-sec at 25 °C(3) determined using a structure estimation method(3).

The rate constant for the vapor-phase reaction of 1-dodecene with photochemically-produced hydroxyl radicals has been estimated as 38X10-12 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 10 hr at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of 1-dodecene with ozone has been estimated as 1.2X10-17 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 23 hrs at an atmospheric concentration of 7X10+11 ozone radicals per cu cm(1).

An estimated BCF of 310 was calculated for 1-dodecene(SRC), using an estimated log Kow of 6.10(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 high.

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-dodecene can be estimated to be 5900(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-dodecene is expected to be immobile in soil(SRC).

The Henry's Law constant for 1-dodecene is estimated as 4.25 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 1-dodecene is expected to volatilize rapidly from moist soil and water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 1.324 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 120 hours(SRC). However, the volatilization half-life does not take into account the effects of adsorption. An estimated Koc of 5900 (SRC), from a log Kow of 6.10 (SRC) and a regression-derived equation (3), suggests that volatilization could be attenuated by adsorption to suspended solids and sediments in water (SRC). This is apparent from the results of two EXAMS model runs, one in which the effect of adsorption was considered, yielding an estimated half-life of 39 days in a model pond 2 m deep, and one in which the effect of adsorption was ignored, yielding an estimated half-life of 45 hr in a model pond 2 m deep (4). 1-Dodecene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces will occur(SRC). The potential for volatilization of 1-dodecene from dry soil surfaces is not expected(SRC) based upon an estimated vapor pressure of 0.0159 mm Hg 25 °C(SRC).
