10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

Flammable liquidThe vapour is heavier than air and may travel along the ground; distant ignition possible. Vapours are uninhibited and may polymerize, causing blockage of vents.Peroxidizable monomer, such as VINYLIDENE CHLORIDE, may initiate exothermic polymerization of the bulk material [Bretherick 1979. p. 160, 187]. Mixing vinylidene chloride in equal molar portions in a closed container with any of the following substances caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, or oleum [NFPA 1991]. Its reaction products with ozone are particularly dangerous [Dow Chemical, 1968]. This may extend to other powerful oxidants, as various peroxides are produced.

10.4 Conditions to avoid

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill); Conditions: static bioassay, 21-23°C, water hardness 32-48 mg/L CaCO3, pH 6.7-7.8, dissolved oxygen 7.0-8.8 mg/L; Concentration: 74 mg/L for 24 and 96 hr
  • Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (Water flea, first instar); Conditions: freshwater, static, 17°C, pH 7.9, hardness 100 mg/L CaCO3, alkalinity 85 mg/L CaCO3, dissolved oxygen >60%; Concentration: 11600 ug/L for 24 hr (95% confidence interval: 9000-14000 ug/L) /99.5% AI
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: 1,1-Dichloroethylene, present at 9.7 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 2 mg/L and the Closed Bottle Test(1). In another study, 45-78% of the chemical was lost in 7 days when incubated with a wastewater inoculum; however, a sizeable fraction of the loss was due to volatilization(2). 97% of 1,1-dichloroethylene was reported to be removed in a municipal wastewater plant(3). 1,1-Dichloroethylene at a concn of 160 ug/L was degraded using continuous mixed, batch-fed reactors at a 20-day operating solids retention time(4). 1,1-Dichloroethylene had a biodegradation half-life of 1.25 yrs in ground water from a former manufacturing facility in NJ(5).

12.3 Bioaccumulative potential

BCFs of 2.5 to 6.4 and <13 were measured for 1,1-dichloroethylene at concentrations of 0.5 and 0.05 mg/L, respectively(1). According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc for 1,1-dichloroethylene has been measured as 64(1) and 65(2). According to a classification scheme(3), this Koc value suggests that 1,1-dichloroethylene is expected to have high mobility in soil. A Koc of 293 was measured in sewage solids(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Extremely flammable. May form explosive peroxides. Harmful by inhalation.Possible risk of irreversible effects.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Prolonged or repeated skin contact may cause severe exacerbation. A single prolonged skin exposure is not likely to result in the material being absorbed in harmful amounts.
Ingestion:
Harmful if swallowed. Possible aspiration hazard.
Inhalation:
May cause liver and kidney damage. Causes irritation of the mucous membrane and upper respiratory tract. Vinylidene chloride is highly volatile. Its odor is not adequate as a warning characteristic.
Overexposure produces central nervous system depression.
Chronic:
May cause liver and kidney damage. Chronic exposure may cause lung damage. Laboratory experiments have resulted in mutagenic effects.

Section 4 - FIRST AID MEASURES
  Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Antidote: None reported.

Section 5 - FIRE FIGHTING MEASURES
  General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air.
During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Fire or excessive heat may result in violent rupture of the container due to bulk polymerization.
Extremely flammable liquid and vapor. Vapor may cause flash fire.
Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. Fight fire from protected location or maximum possible distance.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.
Place under an inert atmosphere. A vapor suppressing foam may be used to reduce vapors.

Section 7 - HANDLING and STORAGE
  Handling:
Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed.
Handle under an inert atmosphere. Store protected from air. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Keep away from heat, sparks and flame. Avoid breathing vapor or mist. Destroy contaminated leather clothing. Pure vapor will be uninhibited and may polymerize in vents or other confined spaces. Materials of construction recommended for vinylidene chloride monomer include steel, stainless steel, and baked phenolic-lined steel. Recommended gasketing materials include Teflon and Viton fluoroelastomers.
Storage:
Keep away from sources of ignition. Do not store in direct sunlight.
Store in a tightly closed container. Purge container with nitrogen before resealing. Keep dry. Store in a cool, dry, well-ventilated area away from incompatible substances. Refrigerator/flammables. Do not expose to air. Do not store in aluminum containers. Long-term storage is not recommended. Do not store in copper or copper alloy storage vessels.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Use explosion-proof ventilation equipment.
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
