Hazard Predictions

• Corrosive: Reaction products may be corrosive
• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive
• Toxic: Reaction products may be toxic

Inorganic cyanides, which are mild reducing agents, can react violently with strong oxidants (Gail, E. et al. 2004. Cyano Compounds, Inorganic. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA (Online); Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 975; Fire and Explosion Risks, von Schwartz, E., London, Griffin, 1918, p. 399, 327; Safety in the Chemical Laboratory, Pieters, H. A. J., Creyghton, J. W., London, Academic Press, 2nd Edition, 1957. pp. 30).

When inorganic cyanides react with oxidants, inert N2 and CO2 gases are released (Gail, E. et al. 2004. Cyano Compounds, Inorganic. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA (Online)).

Reactions between inorganic cyanides and hypochlorites at a pH lower than 9 yield toxic and explosive NCl3 gas (Wallace, V. Chemical and Engineering News 56(4):3; Kirk-Othmer Encyclopedia of Chemical Technology, London, Wiley-Interscience, 3rd Edition, 1980, Vol. 7, p. 322).
