Super toxic; probable oral lethal dose in humans is less than 5 mg/kg or a taste (less than 7 drops) for a 70 kg (150 lb.) person. Vapors are highly irritant and very poisonous. Individuals with chronic diseases of the kidneys, respiratory tract, skin, or thyroid are at greater risk of developing toxic cyanide effects. (EPA, 1998)
Cyanokit is indicated for the treatment of known or suspected cyanide poisoning. ... If clinical suspicion of cyanide poisoning is high, Cyanokit should be administered without delay.... Cyanokit (hydroxocobalamin for injection) 5 g is a cyanide antidote package which contains two colorless 250 mL glass vials, each of which contains 2.5 g dark red lyophilized hydroxocobalamin, pH adjusted with hydrochloric acid, two transfer spikes, one IV administration set, one quick use reference guide and one package insert. The action of Cyanokit in the treatment of cyanide poisoning is based on its ability to bind cyanide ions. ...Caution should be exercised when administering other cyanide antidotes simultaneously with Cyanokit, as the safety of co-administration has not been established. If a decision is made to administer another cyanide antidote with Cyanokit, these drugs should not be administered concurrently in the same IV line. Cyanide
If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use foam, dry chemical, or carbon dioxide. Cool all affected containers with flooding quantities of water. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities of spray and fog.
Cyanogen bromide is not combustible itself, but impure cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Vapors are highly irritating. When material is heated to decomposition, it emits very toxic fumes of cyanide and bromide. Avoid water, acids. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control. (EPA, 1998)
In case of fire in the surroundings, use appropriate extinguishing media.

In the event of a spill, sweep up cyanogen bromide, place in an appropriate container, and dispose of properly. Respiratory and appropriate impermeable protective gloves and clothing should be worn while conducting cleanup of this highly toxic substance.
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Cyanogen bromide is a colorless to white crystalline solid with a penetrating odor. It is slightly soluble in water. It is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a flammable and poisonous gas. Contamination with many materials can cause rapid decomposition of the material. It is toxic by inhalation of its vapors or by the hydrogen cyanide from decomposition or by ingestion. Toxic oxides of nitrogen are produced in fire involving this material. It is used in gold extraction, to make other chemicals, and as a fumigant.

Decomposes on heating and on contact with acids. This produces highly toxic and flammable hydrogen cyanide (see ICSC 0492) and corrosive hydrogen bromide (see ICSC 0282). Reacts with strong oxidants. Reacts slowly with water and moisture. This produces hydrogen bromide and hydrogen cyanide. Attacks many metals in the presence of water.
Cyanogen bromide is moderately endothermic ... & shows evidence of instability.
NoncombustibleThe vapour is heavier than air.CYANOGEN BROMIDE is not combustible itself, but impure cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control. [EPA, 1998]. Benzene and cyanogen halides yield HCl as a byproduct (Hagedorn, F. H. Gelbke, and Federal Republic of Germany. 2002. Nitriles. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA.).

The substance is severely irritating to the eyes, skin and respiratory tract. Inhalation of the vapour may cause lung oedema. See Notes. The effects may be delayed. The substance may cause effects on the cellular respiration. This may result in convulsions, unconsciousness and respiratory failure. Medical observation is indicated. Exposure could cause death.

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.

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.Sublimes at room temperature.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.Commercial products are generally solutions in chloroform.
