4.2 Most important symptoms/effects, acute and delayedExcerpt from ERG Guide 130P [Flammable Liquids (Water-Immiscible / Noxious)]: May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryIf this chemical gets into the eyes, irrigate immediately. If this chemical contacts the skin, wash with soap promptly. If a person breathes in large amounts of this chemical, move the exposed person to fresh air at once and perform artificial respiration. ... /1,2-Dichloroethylene/
5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaIf material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. /1,2-Dichloroethylene/
5.2 Specific hazards arising from the chemicalExcerpt from ERG Guide 130P [Flammable Liquids (Water-Immiscible / Noxious)]: 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. (ERG, 2016)

10.2 Chemical stabilityStable under recommended storage conditions.
10.3 Possibility of hazardous reactionsSometimes thought to be nonflammable, however, it is a dangerous fire hazard when exposed to heat or flame. Reaction with solid caustic alkalies or their concentrated solns produces chloracetylene gas, which ignites spontaneously in air.The vapour is heavier than air and may travel along the ground; distant ignition possible.1,2-DICHLOROETHYLENE and potassium hydroxide forms chloroacetylene, which is explosive and spontaneously flammable in air. It is highly toxic, Rutledge, p134(1968).

AEROBIC: Chlorinated ethenes generally resist biodegradation when incubated under aerobic conditions(1). cis-1,2-Dichloroethylene, present at 2.6 mg/L reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 1 drop/L and the Japanese MITI test(2). In an enrichment biodegradability screening test employing a wastewater inoculum, the average total loss for cis-1,2-dichloroethylene, present at 5 ppm, was 54% in 7 days; 34% loss due to volatilization occurred in 10 days(3). Using enriched methane-utilizing bacteria developed from a sediment mixed culture, CO2-labeled cis-1,2-dichloroethylene, present at 660 ppb was completely degraded within 50 hours; degradation products were not identified(4). Mineralization of C14-labeled 1,2-dichloroethylene (mixture of 20% trans and 71% cis isomers) was observed under aerobic conditions in streambed sediments characterized by a high content of natural organic matter (2.5% dry mass organic content) and saturated with humic acid-laden black water(5); 67% of C14-labeled CO2 was recovered in 50 days(5) which corresponds to a first-order degradation half-life of 31 days(SRC). Biotransformation of cis-1,2-dichloroethylene was increased with the addition of glucose in aerobic studies done with two aquifer subsoils and one river sediment(6). cis-1,2-Dichloroethylene, a degradation product of pollutants including tetrachloroethylene and trichloroethylene, was degraded by Dehalococcoides ethenogenes strain 195 under aerobic conditions(7). Aerobic cometabolism of cis-1,2-dichloroethylene in five laboratory and field studies had reported first order degradation rates of 0.081 to 1.96/day(8). cis-1,2-Dichloroethylene, present at 170 ug/L, was 90 and 50% biodegraded in 204 days using a chloroethene-contaminated sediment/groundwater (Copenhagen, Denmark, workshop for locomotive engines) inoculum amended with methane and oxygen, respectively. Using a chloroethene-contaminated sediment/groundwater (Frederikssund, Denmark, industrial area), the compound was 20-35% and 40% biodegraded in 97 and 274 days, respectively(9).
12.3 Bioaccumulative potentialAn estimated BCF of 8 was calculated in fish for cis-1,2-dichloroethylene(SRC), using a log Kow of 1.86(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(SRC).
12.4 Mobility in soilThe Koc of cis-1,2-dichloroethylene has been reported to be 49(1). According to a classification scheme(2), this Koc value suggests that cis-1,2-dichloroethylene is expected to have very high mobility in soil.
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 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.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning.
