General Description
Colorless liquid with a distinct odor. An intermediate for hexamethylenediamine and chloroprene. (EPA, 1998)

Hazards

Reactivity Alerts
none
Air & Water Reactions
Insoluble in water.
Fire Hazard
The material will burn, though it may require some effort to ignite. Fire produces irritating and poisonous gases. When heated to decomposition, it emits toxic fumes of chlorine-containing compounds. (EPA, 1998)
Health Hazard
(Non-Specific -- Dichlorobutene) Liquid and vapors from the material are highly corrosive and may damage skin, eyes, lungs, and internal organs. (EPA, 1998)
Reactivity Profile
TRANS-1,4-DICHLOROBUTENE will burn, though it may require some effort to ignite. Fire produces irritating and poisonous gases. When heated to decomposition, it emits toxic fumes of chlorine-containing compounds. [EPA, 1998].
Belongs to the Following Reactive Group(s)

Response Recommendations

Isolation and Evacuation
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
Firefighting
Wear positive pressure breathing apparatus and full protective clothing. Move containers from fire area if you can do so without risk. Spray containers with cooling water until well after fire is out. Isolate for one-half mile in all directions if tank car or truck is involved in a fire. For small fires, use dry chemical, carbon dioxide, spray or foam. For large fires, use water spray, fog, or foam. (EPA, 1998)
Non-Fire Response
Keep unnecessary people away; isolate hazard area. Stay upwind; keep out of low areas. Shut off ignition sources. Do not touch spilled material. Use water spray to reduce vapors, but do not get water inside containers. For small spills, absorb with sand or other non-combustible absorbent material. For large spills, dike far ahead of spill for later disposal. (EPA, 1998)
Protective Clothing
For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

First Aid
Warning: Trans-1,4-dichlorobutene liquid and vapor are highly corrosive and may damage skin, eyes, lungs, and internal organs.

Signs and Symptoms of Trans-1,4-Dichlorobutene Exposure: Signs and symptoms of acute exposure to trans-1,4-dichlorobutene may result in irritation of the skin, nose, mouth, and respiratory and gastrointestinal tracts. Delayed lacrimation and eye irritation may occur. Internal organs may be damaged. A trans-1,4-dichlorobutene metabolite, diepoxybutane (DEB), has caused tumors in laboratory animals.

Emergency Life-Support Procedures: Acute exposure to trans-1,4-dichlorobutene may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.

Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to trans-1,4-dichlorobutene.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
4. Transport to a health care facility.

Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self-exposure to trans-1,4-dichlorobutene.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
3. Remove and isolate contaminated clothing as soon as possible.
4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.
5. Wash exposed skin areas thoroughly with soap and water.
6. Treat dermal irritation or burns with standard topical therapy.
7. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
8. Transport to a health care facility.

Ingestion Exposure:
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
2. DO NOT induce vomiting.
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
4. Give the victims water or milk: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Water or milk should be given only if victims are conscious and alert.
5. Transport to a health care facility. (EPA, 1998)
