1,1-Dichloroethane 1,1-Dichloroethane 75-34-3 none 100%

4.First-aid measures

4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest. Refer for medical attention.

In case of skin contact

Remove contaminated clothes. Rinse skin with plenty of water or shower.

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Rinse mouth. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

INHALATION: Irritation of respiratory tract. Salivation, sneezing, coughing, dizziness, nausea, and vomiting. EYES: Irritation, lacrimation, and reddening of conjunctiva. SKIN: Irritation. Prolonged or repeated skin contact can produce a slight burn. INGESTION: Ingestion incidental to industrial handling is not considered to be a problem. Swallowing of substantial amounts could cause nausea, vomiting, faintness, drowsiness, cyanosis, and circulatory failure. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Treatment: Treatment is largely supportive. Watch for respiratory depression and dysrhythmias. Obtain arterial blood gases. Administer oxygen if there is evidence of altered mental status or dyspnea. Treat hypotension with volume expansion and vasopression. Use lidocaine or beta-adrenergic blockers for ventricular dysrhythmias. /Dermal exposure/: Remove contaminated clothing. ... Wash affected area with soap and copious amounts or water. /Ocular exposure/: Irrigate the eye for 15 to 20 minutes. Obtain ophthalmic consultation if symptoms persist. After ingestion: Simple aspiration with a nasogastric tube may be effective because these compounds are liquid. Activated charcoal is probably ineffective. /Inhalation/: Move patient away from the contaminated area. Provide a source of oxygen and prepare for mechanical ventilation. Enhancement of Elimination: Hemodialysis or hemoperfusion is not likely to be useful because of the lipophilic properties of these solvents. Hyperbaric oxygen is experimental. ... Antidotes: Acetylcysteine may restore glutathione stores depleted by the production of free radicals; however, its role in limiting carbon tetrachloride-induced hepetotoxicity remains investigational. Supportive Care: Watch for cardiac dysrhythmias, aspiration pneumonitis, hepatotoxicity, and hypoxic encephalopathy. Monitor for dysrhythmias for at least 24 hours and for hepatorenal failure for approximately 3 days. Obtain a chest radiograph, arterial blood gas, ECG, serum creatinine, and hepatic aminotransferase. Check electrolyte imbalance daily. Treat renal failure with dialysis and hepatic failure with fresh frozen plasma, vitamin K, a low-protein diet, neomycin, and lactulose. Watch fluid and electrolyte balance. /Halogenated hydrocarbons/

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Halogenated aliphatic hydrocarbons are generally considered to be resistant to biodegradation(1). Using an aerobic static-screening-flask test method with a municipal waste water sewage inoculum, 5 and 10 ppm 1,1-dichloroethane incubated for 7 days resulted in 50 and 29% degradation, and 19 and 4% evaporation, respectively(2). No degradation was detected when 1,1-dichloroethane was incubated for 8-16 weeks with uncontaminated samples of subsurface material taken from positions immediately above and below the water table at Pickett, OK and Fort Polk, LA(3). Using well monitoring data from a landfill with a contamination history, the half-life of 1,1-dichloroethane under sulfate-reducing conditions at 10°C was approximated to be 115 days(4). A soil microcosm study simulating gas composition in landfill soil covers found that 1,1-dichloroethane was degraded, but at a rate much slower than 1,2-dichloroethane(5).

12.3 Bioaccumulative potential

An estimated BCF of 7 was calculated in fish for 1,1-dichloroethane(SRC), using a log Kow of 1.79(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). All of the chloroethanes have an elimination half-life of < 2 days as measured by whole body levels in exposed bluegills(4).

12.4 Mobility in soil

The measured Koc of 1,1-dichloroethane in soil has been reported to be 30(1,2). Sorption studies using sea sediment taken from the Belgian Continental Shelf of the North Sea in October 1993 determined a Koc of 9.2(3). According to a classification scheme(4), these Koc values suggest that 1,1-dichloroethane is expected to have very high mobility in soil. 1,1-Dichloroethane was readily leached from material representative of waste at land disposal sites(5) and was found in leachate from a simulated landfill lysimeter used to study the codisposal of metal plating sludge and municipal waste(6).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 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.

Contaminated packaging

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.
