Rinse mouth. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 159 [Substances (Irritating)]: Inhalation of vapors or dust is extremely irritating. May cause burning of eyes and flow of tears. May cause coughing, difficult breathing and nausea. Brief exposure effects last only a few minutes. Exposure in an enclosed area may be very harmful. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Aliphatic hydrocarbons and related compounds
SECTION 5: Firefighting measures

Persistence and degradability
AEROBIC: 1,1,2,2-Tetrabromoethane, present at 100 mg/l, reached 29% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(1).
Bioaccumulative potential
BCF values of <8.2 and 0.5 to 7 were measured for 1,1,2,2-tetrabromoethane at compound concns of 1 ug/l and 10 ug/l, respectively(1). According to a classification scheme(2), these values BCF suggest that bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of 1,1,2,2-tetrabromoethane is estimated as 120(SRC), using a water solubility of 678 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,1,2,2-tetrabromoethane is expected to have high mobility in soil(SRC).

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.
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.
