Cyanide poisoning may result from a broad range of exposures Fire In industrialized countries, the most common cause of cyanide poisoning is domestic fires Cyanide can be liberated during the combustion of products containing both carbon and nitrogen

This process depletes the concentration of the cyanide ions in the blood and thus reduces the amount of cyanide available for reaction with the iron and deactivating it The most important qualities of a good antidote for cyanide poisoning are: It has to react with the cyanide ion very rapidly and irreversibly

Sodium cyanide is water-reactive Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas Sodium cyanide solution in water is a strong base it reacts violently with acid and is corrosive Sodium cyanide is incompatible with strong oxidants

Cyanide is a cellular toxin that binds to cytochrome oxidase, inhibiting cellular respiration Antidotes either directly counteract cyanide's toxicity on the electron transport chain or help the body eliminate the cyanide molecule Administration of antidotes is critical for life-threatening intoxication

The presence of cyanide-soluble copper affects gold and silver recovery from the cyanide solutions In the Merrill-Crowe process, the copper is precipitated along with gold and silver, resulting in a higher consumption of zinc dust, fluxes in the smelting of the precipitate and shorter life for crucibles For these reasons, copper must

an antidote as some cyanide antidotes have severe side effects if administered in the absence of cyanide poisoning or if the dose is too great If a history of exposure to cyanide has been confirmed and the patient presents with, or develops, severe symptoms

Cyanide poisoning can be further treated by medical professionals Often patients are given oxygen Two antidotes sodium nitrite and sodium thiosulfate are usually used to stop the effects of serious cyanide poisoning Other drugs may be necessary to control additional health effects of cyanide such as seizures

Administer Cyanide Antidote as directed below CYANIDE ANTIDOTE Actions: Sodium Nitrite reacts with haemoglobin to form methemoglobin The latter removes cyanide ions from various tissues and couple with them to become cyanmethemglobin, which has a relatively low toxicity The function of Sodium thiosulfate is to convert cyanide to thiocyanate
