Hazards and Protection.
Protect from water.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Safety goggles; gloves; adequate ventilation; provisions for flushing eyes or skin with water.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Use water spray to knock-down vapors. Do not use water on material itself. Neutralize spilled material with crushed limestone, soda ash, or lime. Vapor knockdown water is corrosive or toxic and should be diked for containment. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder. Water spill: If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Decomposes violently on contact with moisture. Highly reactive. Hydrolyzes readily. Decomposition products are corrosive and toxic fumes of carbonyl bromide and bromine.
React vigorously with bases, both organic and inorganic Incompatible with oxidizing agents and alcohols May react vigorously or explosively
When heated to decomposition, it emits highly corrosive and toxic fumes of carbonyl bromide and bromine. Decomposed by water to acetic and hydrobromic acids with release of heat.
Use dry chemical or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Very flammable. Combustion probable.
Flashback along vapor trail may occur.
Toxic and irritating hydrogen bromide fumes may form in fires.
Abnormally low blood pressure may occur after ingestion with corrosive injury and hemorrhage from the gastrointestinal tract. Abnormal neuropsychologic function has been reported following hydrochloric acid exposure from a leaking tanker truck.
Ingestion of acids may result in burns, gastrointestinal bleeding, gastritis, perforations, dilation, edema, necrosis, vomiting, stenosis, fistula, and duodenal/jejunal injury.
Inhalation may produce dyspnea, pleuritic chest pain, upper airway edema, pulmonary edema, hypoxemia, bronchospasm, pneumonitis, and persistent pulmonary function abnormalities. Airway hyperreactivity has also been reported.
Tearing, epistaxis, photophobia, blepharospasm, and brown discoloration of mucous membranes and the tongue may be noted.
Seek medical assistance.
Remove victim from exposure; if breathing has stopped, give artificial respiration; if breathing is difficult, give oxygen; watch for delayed lung damage.
Flush with soap and water; treat burns as needed.
Flush with water for at least 15 min.; get medical attention.
