SECTION 4: First aid measures

Description of first aid measures

If inhaled

Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.

Following skin contact

Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Following eye contact

Rinse with pure water for at least 15 minutes. Consult a doctor.

Following ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

Most important symptoms and effects, both acute and delayed

Inhalation of vapor irritates nose and throat. Contact with eyes causes intense irritation and tears. Contact of liquid with skin causes severe blistering and dermatitis. Ingestion causes severe irritation of mouth and stomach. (USCG, 1999)

Indication of any immediate medical attention and special treatment needed

Stabilization: Treatment is largely supportive. Watch for respiratory depression & arrhythmias. Obtain arterial blood gases. Administer oxygen if there is evidence of altered mental status or dyspnea. Treat hypotension with volume expansion & vasopression. Use lidocaine or beta-blockers for ventricular arrhythmias. Skin: Remove contaminated clothing. Wash affected area with soap & copious amounts or water. Eye: Irrigate the eye for 15-20 min. Obtain a consultation if symptoms persist. Oral: Most of the halogenated solvents ingested in quantities of 1-2 swallows may be partially removed by ipecac-induced emesis if admin within a few hr to a patient who has not lost the gag reflex, is not seizing, is not markedly lethargic, or is not in coma. Observe the patient in the upright position to lessen the possibility of aspiration. Activated charcoal is probably ineffective. Inhalation: Move from the contaminated area. Provide a source of oxygen & prepare for mechanical ventilation. If the patient is unconscious & the pulse is absent, initiate CPR measures. Enhancement of Elimination: Maintain good ventilation. Hemodialysis or hemoperfusion are not likely to be useful because of the high lipophilic properties of these solvents. Antidote: N-acetylcysteine may restore depleted glutathione stores, but no adequate clinical studies are available to validate this possible treatment. Supportive Care: Watch for cardiac dysrhythmias, aspiration pneumonitis, hepatotoxicity, & hypoxic encephalopathy. Monitor for arrhythmia for at least 24 hr & for hepatorenal failure for about 3 days. Obtain a chest x-ray, arterial blood gas, EKG, serum creatinine, & hepatic aminotransferase. Check electrolyte imbalance daily. Treat renal failure with dialysis & hepatic failure with fresh frozen plasma, vitamin K, a low-protein diet, neomycin, & lactulose. Watch fluid & electrolyte balance. Halogenated hydrocarbons

SECTION 5: Firefighting measures

Extinguishing media

If material on fire or involved in fire: Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Solid streams of water may be ineffective. Use foam, dry chemical, or carbon dioxide. Use water spray to knock-down vapors. Dichlorobutene

Specific Hazards Arising from the Chemical

Special Hazards of Combustion Products: Decomposition vapors contain phosgene and hydrogen chloride gases; both are toxic and irritating. (USCG, 1999)

Advice for firefighters

Wear self-contained breathing apparatus for firefighting if necessary.

NFPA 704

HEALTH 4 Very short exposure could cause death or major residual injury (e.g. hydrogen cyanide, phosgene, methyl isocyanate, hydrofluoric acid)
FIRE 2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
REACT 1 Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene)

SECTION 6: Accidental release measures

Personal precautions, protective equipment and emergency procedures

Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.

Environmental precautions

Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.

Methods and materials for containment and cleaning up

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.

SECTION 7: Handling and storage

Precautions for safe handling

Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

SECTION 10: Stability and reactivity


Highly flammable. Reacts slowly with water to form hydrochloric acid. Insoluble in water.

Chemical stability

Reacts slowly with water to form hydrochloric acid. Dichlorobutene

Possibility of hazardous reactions

Flammable /Dichlorobutene/Halogenated unsaturated aliphatic compounds, such as 1,4-DICHLORO-2-BUTENE, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Conditions to avoid

no data available

Incompatible materials

Hazardous decomposition products

When heated to decomposition it emits toxic fumes of /hydrogen chloride/.

Persistence and degradability

Soil degradation studies conducted with 1,4-dichloro-2-butene (cis-isomer) over a one week incubation period in a sandy loam and silt loam soils found degradation half-lives of 1.8 to 2.5 days in both sterile and non-sterile soils(1); degradation rates in non-sterile soils were not significantly faster than in sterile soils indicating that abiotic or evaporative processes were more important than biological processes for 1,4-dichloro-2-butene(1,2); similar results for the trans-isomer are expected because of the similar structure(SRC).

Bioaccumulative potential

An estimated BCF of 14 was calculated for 1,4-dichloro-trans-2-butene(SRC), using a water solubility of 850 mg/l(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 sandy loam and silt loam soils, the Koc of 1,4-dichloro-2-butene (cis-isomer) was experimental determined to be 215(1). According to a suggested classification scheme(2), this Koc value suggests that 1,4-dichloro-trans-2-butene will have moderate mobility in soil because of the similar structure(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.

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.
