Potassium Ferricyanide - Safety

Safety

Potassium ferricyanide has very low toxicity, its main hazard being that it is a mild irritant to the eyes and skin. However, under very strongly acidic conditions, highly toxic hydrogen cyanide gas is evolved, according to the equation:

6 H+ + 3− → 6 HCN + Fe3+

The reaction with hydrochloric acid is as follows:

6 HCl + K3 → 6 HCN + FeCl3 + 3 KCl

Famous quotes containing the word safety:

    An evident principle ... is the principle of justice to all peoples and nationalities, and their right to live on equal terms of liberty and safety with one another, whether they be strong or weak.
    Woodrow Wilson (1856–1924)

    Perhaps in a book review it is not out of place to note that the safety of the state depends on cultivating the imagination.
    Stephen Vizinczey (b. 1933)

    Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?
    Jean Genet (1910–1986)
