Water soluble.

Salts, Acidic

Acidic salts, such as COBALTOUS BROMIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. When heated to decomposition can give off highly toxic fumes of Br (USCG, 1999).

Wear goggles, self-contained breathing apparatus and rubber overclothing (including gloves). (USCG, 1999)|Eye/face protection: Face shield and safety glasses. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).|Skin protection: Handle with gloves.|Body Protection: Complete suit protecting against chemicals. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.|Respiratory protection: Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.|Advice for firefighters: Wear self-contained breathing apparatus for firefighting if necessary.

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Methods and materials for containment and cleaning up: Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal.|Liquid material spills can be copiously flushed with water and channeled to a treatment system or holding tank for reclamation or proper disposal. Spills of dry material can be removed by vacuuming or wet mopping. Some spills can be removed by hosing, first with a mist of water to dampen the spilled material and then with a more forceful stream that flushes it into a holding tank or other facility for handling contaminated water. Work surfaces or contaminated clothing should never be cleaned by dry sweeping or blowing with pressurized hoses. Recovery systems used to reclaim waste metals should comply with federal, state, and local regulations. All waste materials generated in the handling of cobalt-containing substances should be disposed of in compliance with federal, state, and local regulations. /Cobalt and cobalt salts/

Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Cobaltous bromide is included on this list.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 1000 lb or 454 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

IDENTIFICATION AND USE: Cobaltous bromide occurs as a bright green solid or lustrous green crystalline leaflets. It is used chiefly in hygrometers, and also in catalysts for organic reactions. HUMAN EXPOSURE AND TOXICITY: There are no data available. ANIMAL STUDIES: There are no data available.

Cobaltous bromide's production and use in hygrometers and as a catalyst for organic reactions(1) may result in its release to the environment through various waste streams(SRC).

ATMOSPHERIC FATE: Inorganic cobalt compounds are nonvolatile and released into the atmosphere in particulate form(1). Particulate-phase cobalt compounds are removed from the air by wet and dry deposition(SRC). Cobalt has been detected in atmospheric deposition(2) and in rain-snow precipitation(3).

Food Chain Concentration Potential: Microorganisms concentrate the cobalt (from cobaltous bromide) in water up to 1000 to 1500 times(1).

Occupational exposure to cobaltous bromide may occur through inhalation of dust and dermal contact with this compound at workplaces where cobaltous bromide is produced or used. (SRC)
