Potential Health Effects
----------------------------------
Vapors of tetrabromoethane are extremely damaging to the liver. Workers should have a preplacement and annual physical examination stressing liver function.
Inhalation:
Toxic. Vapors are irritating to mucous membranes and respiratory tract. May cause headache, loss of appetite, nausea, abdominal pain, kidney, liver and lung damage. Symptoms of liver damage are dark urine and jaundice. Inhalation of high concentrations may affect the central nervous system and have a narcotic effect.
Ingestion:
Highly toxic by ingestion. Symptoms may parallel those from inhalation.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain. May cause dermatitis. May be absorbed through the skin with possible systemic effects. Prolonged exposure may cause blistering especially if it gets in shoes or underneath clothes.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Chronic exposure may affect liver, kidney, and lungs.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance.
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly clean shoes before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Fire:
Autoignition temperature: 335C (635F)
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Collect liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer!
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
1 ppm (TWA)
-ACGIH Threshold Limit Value (TLV):
1 ppm (TWA)
- NIOSH Immediately Dangerous to Life or Health (IDLH): 8 ppm
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained breathing apparatus. Breathing air quality must meet the requirements of the OSHA respiratory protection standard (29CFR1910.134).
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Appearance:

Hazardous Decomposition Products:
When heated, emits highly toxic fumes of bromine, hydrogen bromide and carbonyl bromide.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Incompatible with oxidizers, caustics, alkalis, hot iron, and reducing metals such as aluminum, magnesium, and zinc in the presence of steam. Softens or destroys most plastics and rubber.
