SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces toxic and corrosive fumes of hydrogen cyanide, hydrochloric acid and nitrogen oxides. Reacts slowly with water and water vapour. This produces hydrogen chloride.
Cyanogen chloride (CK) decomposes on heating, producing toxic and corrosive fumes (hydrogen cyanide, hydrochloric acid, and nitrogen oxides). See the emergency response cards for hydrogen cyanide and hydrochloric acid.Cyanogen chloride (CK) reacts slowly with water or water vapor to form toxic hydrogen cyanide and hydrogen chloride. See the emergency response cards for hydrogen cyanide and hydrogen chloride.Cyanogen chloride (CK) is incompatible with or may react with most basic and acidic solvents including water.Cyanogen chloride (CK) is unstable; it may be stabilized (inhibited) to prevent polymerization.
Chemical stability
Tends to form polymers on storage.
Possibility of hazardous reactions
Not combustible. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic gases including cyanide gas in a fire.The gas is heavier than air.,Vapors may be heavier than air. They will spread along the ground and collect and stay in poorly-ventilated, low-lying, or confined areas (e.g., sewers, basements, and tanks).Hazardous concentrations may develop quickly in enclosed, poorly-ventilated, or low-lying areas. Keep out of these areas. Stay upwind.CYANOGEN CHLORIDE may trimerize violently to form cyanuric chloride, catalyzed by hydrogen chloride or ammonium chloride. Reacts exothermically with alkenes and alkynes. 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.).

Persistence and degradability
Cyanogen chloride is extremely volatile and hydrolyzes rapidly(1), suggesting that biodegradation will not be an important environmental fate process(SRC).[(1) Munro NB et al; Environ Health Perspect 107: 933-74 (1999)] Full text: PMC1566810
Bioaccumulative potential
Cyanogen chloride is extremely volatile and hydrolyzes rapidly(1), suggesting that bioconcentration will not be an important environmental fate process(SRC).[(1) Munro NB et al; Environ Health Perspect 107: 933-74 (1999)] Full text: PMC1566810
Mobility in soil
The high volatility and rapid hydrolysis of cyanogen chloride(1) would suggest that adsorption to soil and sediment is not an important environmental fate process(SRC).[(1) Munro NB et al; Environ Health Perspect 107: 933-74 (1999)] Full text: PMC1566810

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.

Other Information
The occupational exposure limit value should not be exceeded during any part of the working exposure.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 is therefore essential.Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder).Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
