UN#: 1605
                  Synonyms include 1,2-dibromoethane, glycoldibromide, 
                    and bromofume. 
                  
                    - Persons whose clothing or skin is contaminated with liquid 
                      ethylene dibromide (above 50ºF) can secondarily contaminate 
                      others by direct contact or through offgassing vapor. 
                    
 - A liquid at room temperature, ethylene dibromide readily 
                      penetrates skin, cloth, and other protective materials such 
                      as rubber and leather. It is nonflammable. 
                    
 - Ethylene dibromide is a colorless, heavy liquid with a 
                      sweet chloroform-like odor. It's odor is not detectable 
                      at a low enough concentration to be considered a warning 
                      of excessive exposure. 
                    
 - Absorption can occur by the inhalation, oral, and dermal 
                      routes. It is toxic by these three routes of exposure. Toxicity 
                      is thought to be due to metabolic products of ethylene dibromide. 
                  
 
                  
 General Information
Description
                  Ethylene dibromide is a nonflammable 
                    colorless liquid with a sweet chloroform-like odor at room 
                    temperature above 50ºF (10ºC). It is slightly soluble 
                    in water and soluble in most organic solvents. It is heavier 
                    than water. When heated to decomposition, it may release gases 
                    and vapors such as hydrogen bromide, bromine, and carbon monoxide. 
                    Ethylene dibromide should be stored in a dry place at ambient 
                    temperature.
                  
Routes of Exposure
Inhalation
                  Inhalation is an important route of exposure. 
                    Ethylene dibromide's odor is not detectable at a low enough 
                    concentration to be considered a good warning of excessive 
                    exposure. Ethylene dibromide vapors are heavier than air and 
                    can accumulate in poorly ventilated or low-lying areas. 
                  Fatalities have occurred among workers 
                    cleaning a tank containing residues of ethylene dibromide. 
                    The dermal route also contributed to the exposure. 
                  Children exposed to the same levels of 
                    ethylene dibromide as adults may receive larger doses because 
                    they have greater lung surface area:body weight ratios and 
                    higher minute volume:weight ratios. In addition, they may 
                    be exposed to higher levels than adults in the same location 
                    because of their short stature and the higher levels of ethylene 
                    dibromide vapors found nearer to the ground. 
                
Skin/Eye Contact
                  Ethylene dibromide can penetrate ordinary 
                    rubber gloves and leather. Prolonged skin contact with the 
                    liquid may cause erythema, blistering, and skin ulcers. Skin 
                    absorption may contribute to systemic toxicity. 
                  Because of their relatively larger surface 
                    area:weight ratio, children are more vulnerable to toxicants 
                    absorbed through the skin. 
Ingestion
                  Acute toxic effects, including fatal 
                    systemic poisoning, can result from ingestion. Rapid effects 
                    following ingestion can include abdominal pain, diarrhea, 
                    nausea, vomiting, and drowsiness.
                    
Sources/Uses
                  Ethylene dibromide is produced by liquid-phase 
                    bromination of ethylene at 35-85ºC. This is followed 
                    by neutralization to free acid and purification by distillation. 
                    Ethylene dibromide was used extensively as a scavenger for 
                    lead in gasoline and as a pesticide and an ingredient of soil, 
                    vegetable, fruit, and grain fumigant formulations. However, 
                    these uses have almost disappeared in the United States. It 
                    is used to some extent as a chemical intermediate, gauge fluid, 
                    and as a nonflammable solvent for resins, gums, and waxes.

Health Effects
                  
                    - Ethylene dibromide is a liquid at ambient temperatures 
                      that can cause skin, eye, mucous membrane, and respiratory 
                      tract irritation. It may also cause damage to the lungs, 
                      liver, and kidneys. These effects can result from all routes 
                      of exposure. 
                    
 - The systemic effects of ethylene dibromide are in part 
                      due to metabolic conversion to the cell toxicant 2-bromoacetaldehyde. 
                    
 - Persons with pre-existing skin disorders or eye problems, 
                      or impaired liver, kidney, or respiratory tract function 
                      may be more susceptible to the effects of ethylene dibromide. 
                  
 
                  
Acute Exposure
                  Ethylene dibromide alkylates macromolecules 
                    causing cellular disruption and reduced glutathione levels. 
                    Cellular disruption in tissues and organs, such as liver and 
                    kidneys, results in progressive dysfunction. Manifestation 
                    of some of the effects of acute high exposure may be delayed 
                    a few days. 
                  Children do not always respond to chemicals 
                    in the same way that adults do. Different protocols for managing 
                    their care may be needed. 
					
Respiratory
                  Early symptoms of acute exposure include 
                    irritation of the nose and throat. Exposures of moderate to 
                    severe intensity produce respiratory manifestations ranging 
                    from cough, chest pain, and dyspnea to bronchitis, pneumonitis, 
                    pulmonary edema, and hemorrhage. Pulmonary edema occurred 
                    3 days after oral poisoning in one fatal human case. 
                  Children may be more vulnerable because 
                    of higher minute ventilation per kg and failure to evacuate 
                    an area promptly when exposed. Hydrocarbon pneumonitis may 
                    be a problem in children. 
CNS
                  Ethylene dibromide is a mild central 
                    nervous system depressant. Drowsiness has been reported following 
                    ingestion and inhalation. Inhalation of vapors in a confined 
                    oxygen-deficient space has caused rapid loss of consciousness, 
                    coma, and death. 
					
Dermal
                  Liquid ethylene dibromide is a skin irritant. 
                    Brief skin contact or contact with contaminated clothing causes 
                    erythema and discomfort. Splashing of the liquid on the skin 
                    causes a sensation of cooling because the liquid evaporates 
                    quickly. Prolonged skin contact may cause blistering and skin 
                    ulcers (may be delayed 24-48 hours). Ethylene dibromide can 
                    be absorbed through the skin to produce systemic effects. 
                  
                  Exposure to certain chemicals can lead 
                    to Reactive Airway Dysfunction Syndrome (RADS), a chemically- 
                    or irritant-induced type of asthma. 
                  Because of their larger relatively surface 
                    area:body weight ratio, children are more vulnerable to toxins 
                    absorbed through the skin. 
                
Ocular/Ophthalmic
                  Conjunctivitis has been reported after 
                    exposure to ethylene dibromide. Eye contact with the compound 
                    may cause temporary loss of vision because of destruction 
                    of tissues in the eye. 
					
Hepatic
                  Ethylene dibromide poisoning often affects 
                    the liver. Significant liver damage has resulted from inhalation 
                    and ingestion of ethylene dibromide. Necrosis of the liver 
                    was a chief finding in a fatal case of acute oral poisoning. 
                    In two fatal cases of inhalation/dermal exposure, serum aspartate 
                    aminotransferase and lactic dehydrogenase were elevated before 
                    death.
Renal
                  The kidney is often affected in ethylene 
                    dibromide poisoning. Severe renal lesions were reported in 
                    fatal cases of acute oral poisoning and also inhalation poisoning. 
                    Lesions included necrosis of the tubular epithelium, cytoplasmic 
                    vacuolization of the proximal convoluted tubules, and tubular 
                    protein casts.
Gastrointestinal
                  Abdominal pain, nausea, vomiting, and 
                    diarrhea have been reported after ethylene dibromide ingestion.
                    
Metabolic
                  Metabolic acidosis can occur after high 
                    exposure to ethylene dibromide.
                    
Potential Sequelae
                  Patients who develop severe acute neurologic 
                    injury but survive may have both central and peripheral neurologic 
                    effects that persist indefinitely. 
                 
                
Carcinogenicity
 
                  The Department of Health and Human Services (DHHS), the 
					International Agency for Research on Cancer (IARC), and the 
					Environmental Protection Agency (EPA) have not had 
					sufficient evidence to classify elemental mercury as a 
					carcinogen or a noncarcinogen.
					
Chronic Exposure
 
                  No reliable reports exist of adverse 
                    health effects in humans exposed chronically to ethylene dibromide. 
                  
                  Chronic exposure may be more serious 
                    for children because of their potential for a longer latency 
                    period. 
				
                    
Carcinogenicity
 
                  The Department of Health and Human Services 
                    (DHHS) has determined that ethylene dibromide can reasonably 
                    be anticipated to be a human carcinogen, based on ethylene 
                    dibromide-induced tumors in multiple sites and by various 
                    routes of exposure in animals. Results from epidemiological 
                    studies have been inconclusive. 
Reproductive and Developmental Effects
 
                  There is inconclusive but suggestive 
                    evidence that ethylene dibromide may reduce fertility in men. 
                    Antispermatogenic effects have been demonstrated in various 
                    animal species. Ethylene dibromide is included in Reproductive 
                    and Developmental Toxicants, a 1991 report published by 
                    the U.S. General Accounting Office (GAO) that lists 30 chemicals 
                    of concern because of widely acknowledged reproductive and 
                    developmental consequences. 
                  Special consideration regarding the exposure 
                    of pregnant women is warranted, since ethylene dibromide has 
                    been shown to be a genotoxin; thus, medical counseling is 
                    recommended for pregnant women. 
                       
                
 Prehospital Management
                  
                    - Victims exposed only to ethylene dibromide gas do not 
                      pose substantial risks of secondary contamination to personnel 
                      outside the Hot Zone; however, some ethylene dibromide may 
                      permeate clothing. Victims whose clothing or skin is contaminated 
                      with liquid ethylene dibromide (i.e., ambient temperature 
                      higher than 50ºF) can secondarily contaminate response 
                      personnel by direct contact or through off-gassing vapor. 
                    
 
                    - Ethylene dibromide is a mucous membrane, skin, and eye 
                      irritant. It may also cause respiratory distress and pulmonary 
                      noncardiogenic pulmonary edema, liver and kidney toxicity, 
                      drowsiness, coma, and death. Dermal absorption may contribute 
                      to systemic toxicity. 
 
                    - There is no antidote for ethylene dibromide. Treatment 
                      consists of support of respiratory and cardiovascular functions.
 
                  
                        
Hot Zone
                  Rescuers should be trained and appropriately 
                    attired before entering the Hot Zone. If the proper equipment 
                    is not available, or if rescuers have not been trained in 
                    its use, assistance should be obtained from a local or regional 
                    HAZMAT team or other properly equipped response organization.
                    
Rescuer Protection
                  Ethylene dibromide is a highly toxic 
                    systemic poison that is readily absorbed following inhalation 
                    and dermal exposure. 
                  Respiratory Protection: Positive-pressure, 
                    self-contained breathing apparatus (SCBA) with a full facepiece 
                    is recommended in response situations that involve exposure 
                    to potentially unsafe levels of methyl bromide vapor. 
                  Skin Protection: Chemical-protective 
                    clothing (including boots and gloves) is recommended because 
                    ethylene dibromide vapor or liquid can be absorbed through 
                    the skin and may contribute to systemic toxicity. Contact 
                    with liquid ethylene dibromide can cause skin irritation and 
                    blisters. Ethylene dibromide can penetrate ordinary rubber 
                    gloves and leather. 
ABC Reminders
                  Quickly establish a patent airway, ensure 
                    adequate respiration and pulse. If trauma is suspected, maintain 
                    cervical immobilization manually and apply a cervical collar 
                    and a backboard when feasible.
Victim Removal
                  If victims can walk, lead them out of 
                    the Hot Zone to the Decontamination Zone. Victims who are 
                    unable to walk may be removed on backboards or gurneys; if 
                    these are not available, carefully carry or drag victims to 
                    safety. 
                  Consider appropriate management of anxiety 
                    in victims with chemically-induced acute disorders, especially 
                    children who may suffer separation anxiety if separated from 
                    a parent or other adult. 
Decontamination Zone
                  Remove clothing, including footwear, 
                    from all victims because ethylene dibromide persists in cloth, 
                    leather, and rubber. After clothing has been removed, patients 
                    exposed only to the gas who have no skin or eye irritation 
                    may be transferred immediately to the Support Zone. All others 
                    require decontamination as described below.
Rescuer Protection
                  If exposure levels are determined to 
                    be safe, decontamination may be conducted by personnel wearing 
                    a lower level of protection than that worn in the Hot Zone 
                    (described above).
                    
ABC Reminders
                  Quickly establish a patent airway, ensure 
                    adequate respiration and pulse. Stabilize the cervical spine 
                    with a collar and a backboard if trauma is suspected. Administer 
                    supplemental oxygen as required. Assist ventilation with a 
                    bag-valve-mask device if necessary.
Basic Decontamination
                  Victims who are able may assist with 
                    their own decontamination. Remove all contaminated clothing 
                    including footwear. Ethylene dibromide can persist in cloth, 
                    leather, and rubber, and these materials may contribute to 
                    severe chemical burns after prolonged skin contact. Double-bag 
                    contaminated clothing and personal belongings. Leave these 
                    items in the Hot Zone. 
                  Flush exposed skin and hair with water 
                    for at least 15 minutes, then wash twice with mild soap. Rinse 
                    thoroughly with water. Use caution to avoid hypothermia when 
                    decontaminating patients, particularly children or the elderly. 
                    Use blankets or warmers after decontamination as needed.
                  Irrigate exposed or irritated eyes with 
                    plain water or saline for 15 to 20 minutes. Remove contact 
                    lenses if easily removable without additional trauma to the 
                    eye. If pain or injury is evident, continue irrigation while 
                    transferring the victim to the Support Zone. 
                  If ingestion of liquid ethylene dibromide 
                    occurs, do not induce emesis. If the victim is alert 
                    and able to swallow, administer a slurry of activated charcoal 
                    at a dose of 1 g/kg (infant, child, and adult dose). A soda 
                    can and straw may be of assistance when offering charcoal 
                    to a child. 
                  Consider appropriate management of chemically 
                    contaminated children at the exposure site. Also, provide 
                    reassurance to the child during decontamination, especially 
                    if separation from a parent occurs. 
Transfer to Support Zone
                  As soon as basic decontamination is complete, 
                    move the victim to the Support Zone.
					
Support Zone
                  Be certain that victims have been decontaminated 
                    properly (see Decontamination Zone above). Victims 
                    who have undergone decontamination pose no serious risks of 
                    secondary contamination. Support Zone personnel require no 
                    specialized protective gear in such cases. 
					
ABC Reminders
                  Quickly establish a patent airway, ensure 
                    adequate respiration and pulse. If trauma is suspected, maintain 
                    cervical immobilization manually and apply a cervical collar 
                    and a backboard when feasible. Administer supplemental oxygen 
                    as required and establish intravenous access if necessary. 
                    Place on a cardiac monitor.
					
Additional Decontamination
                  Continue irrigating exposed skin and 
                    eyes, as appropriate. 
                  In cases of ingestion of liquid ethylene 
                    dibromide, do not induce emesis. If the victim is alert 
                    and able to swallow, administer a slurry of activated charcoal 
                    at a dose of 1 g/kg (infant, child, and adult dose). A soda 
                    can and straw may be of assistance when offering charcoal 
                    to a child. 
Advanced Treatment
                  In cases of respiratory compromise secure 
                    airway and respiration via endotracheal intubation. If not 
                    possible, perform cricothyrotomy if equipped and trained to 
                    do so. 
                  Treat patients who have bronchospasm 
                    with an aerosolized bronchodilator such as albuterol. 
                  Consider racemic epinephrine aerosol 
                    for children who develop stridor. Dose 0.25-0.75 mL of 2.25% 
                    racemic epinephrine solution, repeat every 20 minutes as needed, 
                    cautioning for myocardial variability. 
                  Patients who are comatose, hypotensive, 
                    or are having seizures or cardiac arrhythmias should be treated 
                    according to advanced life support (ALS) protocols. 
                  If evidence of shock or hypotension is 
                    observed, begin fluid administration. For adults with systolic 
                    pressure less than 80 mm Hg, bolus perfusion of 1,000 mL/hour 
                    intravenous saline or lactated Ringer's solution may be appropriate. 
                    Higher adult systolic pressures may necessitate lower perfusion 
                    rates. For children with compromised perfusion administer 
                    a 20 mL/kg bolus of normal saline over 10 to 20 minutes, then 
                    infuse at 2 to 3 mL/kg/hour. 
					
Transport to Medical Facility
                  Only decontaminated patients or patients 
                    not requiring decontamination should be transported to a medical 
                    facility. "Body bags" are not recommended. 
                  Report to the base station and the receiving 
                    medical facility the condition of the patient, treatment given, 
                    and estimated time of arrival at the medical facility. 
                  If the patient has ingested ethylene 
                    dibromide, prepare the ambulance in case the patient vomits 
                    toxic material or has diarrhea. Have ready several towels 
                    and open plastic bags to quickly clean up and isolate vomitus. 
                  
Multi-Casualty Triage
                  Consult with the base station physician 
                    or the regional poison control center for advice regarding 
                    triage of multiple victims. Because systemic symptoms may 
                    be delayed for several hours after exposure, all exposed patients 
                    should be transported to a medical facility for evaluation. 
                    Symptomatic patients should receive priority in transport.
	
 Emergency Department Management
 
                  
                    - Hospital personnel away from the scene are not at significant 
                      risk of secondary contamination from patients exposed to 
                      vapors of ethylene dibromide or to liquid ethylene dibromide 
                      (ambient temperatures greater than 50ºF); however, 
                      some ethylene dibromide may have permeated clothing. 
 
                    - Ethylene dibromide is a mucous membrane irritant and exposures 
                      to high concentrations can cause eye, skin, and respiratory 
                      tract irritation, as well as pulmonary edema. Dermal absorption 
                      can contribute to systemic toxicity. 
 
                    - High concentrations can also cause drowsiness, coma, and 
                      death. 
 
                    - There is no antidote for ethylene dibromide. Treatment 
                      consists of support of respiratory and cardiovascular functions.
 
                  
                
Decontamination Area
                  Unless previously decontaminated, all 
                    patients suspected of contact with liquid ethylene dibromide 
                    and all victims with skin or eye irritation require decontamination 
                    as described below. Because ethylene dibromide is absorbed 
                    through the skin, don butyl rubber gloves and apron before 
                    treating patients. Ethylene dibromide readily penetrates most 
                    rubbers and barrier fabrics or creams, but butyl rubber provides 
                    good skin protection. All other patients may be transferred 
                    immediately to the Critical Care Area. 
                  Be aware that use of protective equipment 
                    by the provider may cause anxiety, particularly in children, 
                    resulting in decreased compliance with further management 
                    efforts. 
                  Because of their relatively larger surface 
                    area:body weight ratio, children are more vulnerable to toxicants 
                    absorbed through the skin. Also, emergency department personnel 
                    should examine children's mouths because of the frequency 
                    of hand-to-mouth activity among children. 
                
ABC Reminders
                  Evaluate and support airway, breathing, 
                    and circulation. In cases of respiratory compromise secure 
                    airway and respiration via endotracheal intubation. If not 
                    possible, surgically create an airway. 
                  Treat patients who have bronchospasm 
                    with an aerosolized bronchodilator such as albuterol. 
                  Consider racemic epinephrine aerosol 
                    for children who develop stridor. Dose 0.25-0.75 mL of 2.25% 
                    racemic epinephrine solution, repeat every 20 minutes as needed, 
                    cautioning for myocardial variability. 
                  Patients who are comatose, hypotensive, 
                    or have seizures or cardiac arrhythmias should be treated 
                    in the conventional manner. 
                    
Basic Decontamination
                  Patients who are able may assist with 
                    their own decontamination. Remove and double-bag all clothing, 
                    including footwear, because ethylene dibromide penetrates 
                    many materials and can remain trapped in them. Leather absorbs 
                    ethylene dibromide; items such as leather shoes, gloved, and 
                    belts may require disposal by incineration. 
                  Flush exposed skin and hair with water 
                    for at least 15 minutes, then wash twice with mild 
                    soap. Rinse thoroughly with water. Use caution to avoid hypothermia 
                    when decontaminating patients, particularly children or the 
                    elderly. Use blankets or warmers after decontamination as 
                    needed. 
                  Irrigate exposed or irritated eyes with 
                    tap water or saline for 15 to 20 minutes. Remove contact lenses 
                    if easily removable without additional trauma to the eye. 
                    If pain or injury is evident, continue irrigation while transferring 
                    the victim to the Critical Care Area. An ophthalmic anesthetic, 
                    such as 0.5% tetracaine, may be necessary to alleviate blepharospasm, 
                    and lid retractors may be required to allow adequate irrigation 
                    under the eyelids. 
                  If ingestion occurs, do not induce 
                    emesis. If the victim is alert and able to swallow, and 
                    if not already done, administer a slurry of activated charcoal 
                    at a dose of 1 g/kg (infant, child, and adult dose). A soda 
                    can and straw may be of assistance when offering charcoal 
                    to a child. 
Critical Care Area
                  Be certain that appropriate decontamination 
                    has been carried out (see Decontamination Area, above). 
                  
ABC Reminders
                  Evaluate and support airway, breathing, 
                    and circulation as in ABC Reminders above. Establish 
                    intravenous access in seriously ill patients. Continuously 
                    monitor cardiac rhythm. 
                  Patients who are comatose, hypotensive, 
                    or have seizures or cardiac arrhythmias should be treated 
                    in the conventional manner. 
                    
Inhalation Exposure
                  Administer supplemental oxygen by mask 
                    to patients who have respiratory complaints. Treat patients 
                    who have bronchospasm with an aerosolized bronchodilator such 
                    as albuterol. 
                  Consider racemic epinephrine aerosol 
                    for children who develop stridor. Dose 0.25-0.75 mL of 2.25% 
                    racemic epinephrine solution, repeat every 20 minutes as needed, 
                    cautioning for myocardial variability. 
                  Observe these patients for 24 hours using 
                    repeated chest examinations and other appropriate tests. Follow-up 
                    as clinically indicated. 
Skin Exposure
                  If the skin was in contact with concentrated 
                    ethylene dibromide vapor or liquid, chemical burns may result; 
                    treat as thermal burns. Burns may be delayed in onset. 
                  Because of their relatively larger surface 
                    area:body weight ratio, children are more vulnerable to toxicants 
                    absorbed through the skin. 
Eye Exposure
                  Continue irrigation for at least 15 minutes. 
                    Test visual acuity. Examine the eyes for corneal damage and 
                    treat appropriately. Immediately consult an ophthalmologist 
                    for patients who have corneal injuries.
Ingestion Exposure
                  If ingestion of liquid ethylene dibromide 
                    occurs, do not induce emesis. If the victim is alert 
                    and able to swallow, and if not already done, administer a 
                    slurry of activated charcoal at a dose of 1 g/kg (infant, 
                    child, and adult dose). A soda can and straw may be of assistance 
                    when offering charcoal to a child.
                
Antidotes and Other Treatments
                  There is no proven antidote for ethylene 
                    dibromide poisoning. Dimercaprol (BAL) or acetylcysteine (Mucomyst) 
                    have been suggested as antidotes based on the postulated mechanism 
                    of ethylene dibromide's toxicity. However, no adequate studies 
                    have tested the efficacy of these therapies, and they are 
                    not recommended for routine use.
					
Laboratory Tests
					
                  Serum bromide levels can be used to document 
                    that exposure did occur. However, bromide levels do not accurately 
                    predict the clinical course. Routine laboratory studies include 
                    CBC, glucose, and electrolyte determinations. Additional studies 
                    for patients exposed to ethylene dibromide include liver-function 
                    tests and renal-function tests. In cases of inhalation exposure, 
                    chest radiography and arterial blood gas measurements may 
                    be helpful.
Disposition and Follow-up
                  Decisions to admit or discharge a patient 
                    should be based on exposure history, physical examination, 
                    and test results. The probable delay in onset of serious effects 
                    from ethylene dibromide exposure should be considered.
                    
Delayed Effects
                  Because the onset of pulmonary edema 
                    may be delayed for up to several days, patients who have severe 
                    exposure should be monitored with serial examinations before 
                    absence of toxic effects can be assured. If pulmonary edema 
                    is suspected, admit patients to an intensive care unit. Neurological 
                    symptoms also may not develop for several days or weeks. 
Patient Release
                 Patients who have no evidence of neuropsychiatric 
                    or pulmonary effects 24 hours after exposure may be discharged 
                    with instructions to return to the emergency department (ED) 
                    if symptoms develop or recur (see the Ethylene Dibromide--Patient 
                    Information Sheet below).
Follow-up
                  Obtain the name of the patient's primary 
                    care physician so that the hospital can send a copy of the 
                    ED visit to the patient's doctor. 
                  Patients exposed to ethylene dibromide 
                    should be monitored for late neuropsychiatric sequelae. 
                  Patients who have corneal injuries should 
                    be reexamined within 24 hours. 
Reporting
                  Ethylene dibromide is a pesticide. If 
                    a pesticide- or work-related incident has occurred, you may 
                    be legally required to file a report; contact your state or 
                    local health department. 
                  Other persons may still be at risk in 
                    the setting where this incident occurred. If the incident 
                    occurred in the workplace, discussing it with company personnel 
                    may prevent future incidents. If a public health risk exists, 
                    notify your state or local health department or other responsible 
                    public agency. When appropriate, inform patients that they 
                    may request an evaluation of their workplace from OSHA or 
                    NIOSH. See Appendix III for a list of agencies that may be 
                    of assistance.

What is ethylene dibromide?
                  Ethylene dibromide is a colorless liquid 
                    at ambient temperature, with a sweetish odor. Ethylene dibromide 
                    has been used as a scavenger for lead in gasoline and as a 
                    pesticide and an ingredient of soil and grain fumigant formulations. 
                    These uses have virtually disappeared in the United States. 
                    Minor uses include use as a chemical intermediate and as a 
                    nonflammable solvent for resins, gums, and waxes.
What immediate health effects can be caused by exposure to ethylene dibromide?
                  Ingestion of the ethylene dibromide or 
                    inhalation of vapors can cause injury to the brain, lungs, 
                    and throat. High doses can also injure the kidneys and liver. 
                    Contact with the skin and eyes can lead to irritation and 
                    burns and can also contribute to systemic toxicity. Ethylene 
                    dibromide may cause cardiac arrhythmias and sensitization. 
                    Generally, the more serious the exposure, the more severe 
                    the symptoms.
Can ethylene dibromide poisoning be treated?
                  There is no antidote for ethylene dibromide 
                    poisoning, but its effects can be treated and most persons 
                    recover. Persons who have experienced serious symptoms may 
                    need to be hospitalized and may need follow-up examinations 
                    or treatment later on.
Are any future health effects likely to occur?              
                  A single small exposure from which a 
                    person recovers quickly is not likely to cause delayed or 
                    long-term effects. After a serious exposure that causes lung 
                    or nervous system-related problems, permanent brain or lung 
                    damage can result. The Department of Health and Humans Services 
                    has determined that ethylene dibromide can reasonably be anticipated 
                    to be a carcinogen.
What tests can be done if a person has been exposed to ethylene dibromide?
                  Specific tests for the presence of bromide 
                    in blood may provide some useful information to the doctor. 
                    If a severe exposure has occurred, blood and urine analyses 
                    and other tests may show whether the lungs, brain, liver, 
                    or kidneys have been damaged. Testing is not needed in every 
                    case.
                
Where can more information about ethylene dibromide be found?
                  More information about ethylene dibromide 
                    can be obtained from your regional poison control center; 
                    your state, county, or local health department; the Agency 
                    for Toxic Substances and Disease Registry (ATSDR); your doctor; 
                    or a clinic in your area that specializes in occupational 
                    and environmental health. If the exposure happened at work, 
                    you may wish to discuss it with your employer, the Occupational 
                    Safety and Health Administration (OSHA), or the National Institute 
                    for Occupational Safety and Health (NIOSH). Ask the person 
                    who gave you this form for help in locating these telephone 
                    numbers.
