(E)-1,4-DIBROMO-2-BUTENE

PHYSICAL DESCRIPTION: Crystals or white crystalline solid. (NTP, 1992)

none

This chemical may be sensitive to exposure to light and air. Insoluble in water.

This chemical is probably combustible. (NTP, 1992)

SYMPTOMS: Symptoms of exposure to this compound include corrosion, vesication and extreme destruction of tissue of the mucous membranes and upper respiratory tract, eyes and skin. Lacrimation may occur. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. Other symptoms include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Blisters may result from skin contact.

ACUTE/CHRONIC HAZARDS: This compound is a corrosive and vesicant. It is harmful by ingestion, inhalation and skin absorption. This chemical is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes and skin. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide, bromine and hydrogen bromide gas. (NTP, 1992)

(E)-1,4-DIBROMO-2-BUTENE is incompatible with strong oxidizers and strong bases. (NTP, 1992)

Excerpt from 151 [Substances - Toxic (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 car or tank truck 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, 2020)

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

STORAGE PRECAUTIONS: You should protect this chemical from exposure to light. Keep the container tightly closed under an inert atmosphere, and store under ambient temperatures. (NTP, 1992)

MINIMUM PROTECTIVE CLOTHING: If Tyvek protective clothing is not worn during the handling of this chemical, wear disposable Tyvek sleeves taped to your gloves.

RECOMMENDED RESPIRATOR: Where the neat test chemical is stored, weighed and diluted, wear an approved half face respirator equipped with a combination filter cartridge, i.e. organic vapor/acid gas/HEPA, (specific for organic vapors, HCl, acid gas SO2 and a high efficiency particulate filter). Splash proof safety goggles should be worn while handling this chemical. Alternatively, a full face respirator, equipped as above, may be used to provide simultaneous eye and respiratory protection. (NTP, 1992)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.

INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim IMMEDIATELY to a hospital. (NTP, 1992)
