SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Inhalation causes nausea, vomiting, weakness, tremor, epigastric cramps, central nervous depression. Contact with liquid causes irritation of eyes and (on prolonged contact) skin. Ingestion causes slight depression to deep narcosis. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Chlorinated fluorocarbons (CFCs) and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Use dry chemical, foam, carbon dioxide, or water spray. Use flooding quantities of water to blanket the fire. Water may be ineffective. Use water spray to keep fire-exposed containers cool. Fight fire from protected location or maximum possible distance.
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Phosgene and hydrogen chloride fumes may form in fires. Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. (USCG, 1999)
Special protective actions for fire-fighters
Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and under the influence of air, light and moisture. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163). Reacts with strong oxidants. Reacts with copper, copper alloys and bases. This produces toxic chloroacetylene which is spontaneously flammable in contact with air. Attacks plastics.
Chemical stability
Gradually decomposed by air, light, and moisture, forming HCl.
Possibility of hazardous reactions
Flammable liquid.The vapour is heavier than air and may travel along the ground; distant ignition possible.1,2-DICHLOROETHYLENE reacts violently with sodium, sodium hydroxide, copper and copper alloys. It can react with caustic alkynes or their concentrated solutions. It forms explosive mixtures with N2O4. It is incompatible with strong oxidizers. It is corrosive to metals. It attacks some forms of plastics, rubber and coatings. (NTP, 1992)
Conditions to avoid
no data available
Incompatible materials
May release explosive chloroacetylene by the contact with copper or copper alloys.
Hazardous decomposition products
Gradually decomposed by light, air, and moisture to form hydrogen chloride.

Persistence and degradability
AEROBIC: Chlorinated ethenes generally resist biodegradation when incubated under aerobic conditions(1). cis- and trans-1,2-Dichloroethylene, present at 2.62 and 2.32 mg/L, respectively, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum in the Japanese MITI test(2). trans-1,2-Dichloroethylene was recalcitrant in shake flask tests modified to accommodate volatile chemicals(3,4); the concentrations examined in these studies ranged from 0.80 to 25 ppm, and a 21 day acclimation period and the addition of a lactose cometabolite did not alter the biodegradability(3,4). Similarly, no biodegradation occurred in a river die-away test(4). Other studies under aerobic conditions showed similar results of limited degradation for 1,2-dichloroethylene(5). However, mineralization of C14-labeled 1,2-dichloroethylene (mixture of 20% trans- and 71% cisiisomers) 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(6); 67% of C14-labeled CO2 was recovered in 50 days under aerobic conditions(6) which corresponds to a first-order half-life of 31 days(SRC). It has been suggested that ammonia-oxdizing aerobic bacteria and facultative-sulfur bacteria can biodegradae chlorinated aliphatic hydrocarbons(1).
Bioaccumulative potential
An estimated BCF of 8 was calculated in fish for 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).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1,2-dichloroethylene can be estimated to be 40(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1,2-dichloroethylene 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.
