FIRST AID MEASURES First aid measures Product code: S1060 Product name: SILVER CYANIDE, Page 2 / 13 POWDER, PURIFIED General Advice: National Capital Poison Center in the United States can provide assistance if you have a poison emergency and need to talk to a poison specialist. Call 1-800-222-1222. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. First aider needs to protect himself. Skin Contact: Fatal in contact with skin. Wash off immediately with soap and plenty of water. Continue flushing with plenty of water for at least 15 minutes. Remove all contaminated clothes and shoes. Immediate medical attention is required. Call a physician or poison control center immediately. Eye Contact: Flush eyes with water for 15 minutes. Immediate medical attention is required. Call a physician immediately. Inhalation: Move to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. WARNING! It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled or ingested material is toxic, infectious or corrosive. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Immediate medical attention is required. Ingestion: Fatal if swallowed. Do not induce vomiting without medical advice. Never give anything by mouth to an unconscious person. Immediate medical attention is required. Most important symptoms and effects, both acute and delayed Symptoms Causes serious eye irritation It may be absorbed through the skin May cause respiratory irritation Nose and throat irritation Coughing and wheezing Dyspnea (Shortness of breath and difficulty breathing) May cause nausea and headache Dizziness Severe over-exposure can result in death Silver deposits on the conjunctiva or cornea of the eyes (Argyrosis). Argyria (blue-gray discoloration) of the mucous membranes of the upper respiratory tract from chronic inhalation. Localized Argyria from repeated skin contact Indication of any immediate medical attention and special treatment needed Notes to Physician: Antidote: Always have a Cyanide Antidote Kit (Package) when working with cyanide compounds. Get medical advice on how to use it and when it should be used. If cyanide gas is inhaled, break an Amyl nitrate pearl in a cloth and hold it lightly under the nose for 15 seconds. Repeat 5 times at about 15 second intervals. Use artificial respiration if breathing has stopped. If cyanide is swallowed, use Amyl nitrate as previously stated for 15 seconds. Nithidote Kit or Hydroxocobalamin (Cyanokit) are alternate approved treatments. Oxygen therapy may be useful in combination with the above. Protection of first-aiders First-Aid Providers: Avoid exposure to blood or body fluids. Wear gloves and other necessary protective clothing. Dispose of contaminated clothing and equipment as bio-hazardous waste. 5.

  • The Analysis of Cyanide Silver-Plating Solutions
    RP384 THE ANALYSIS OF CYANIDE SILVER-PLATING SOLUTIONS By R. M. Wick ABSTRACT Methods for the analysis of cyanide silver-plating solutions were studied, including the determination of free cyanide, total cyanide, carbonate, chloride, ammonia, silver, iron, copper, and mercury. Electrometric titrations showed that the Liebig method for alkali cyanide is correct to better than 0.2 per cent. Addition of iodide makes the method still more accurate and overcomes the effects of impurities on the titration. The nonagreement of the Liebig and Hannay methods was studied by electro- metric titrations, which showed that the visual Hannay method gives high results although the electrometric Hannay titration is accurate. The determination of total cyanide was accomplished by distillation with sulphuric acid, and of total effective cyanide by titration with iodine. Silver may be separated as silver sulphide, by precipitation with zinc, or by decomposition with acid, after which a determination by any standard method is applicable. Carbonate may be determined by precipitating and filtering out barium car- bonate and titrating it with acid or by titrating a sample with acid after adding silver nitrate to combine with the free cyanide. The usual method for the determination of chloride involves prolonged treat- ment with nitric acid, which converts the precipitated silver cyanide to silver chloride. A new method for separating chloride was investigated in which the silver is precipitated as sulphide and the iron is removed by precipitation as manganous ferrocyanide. The chloride in the filtrate can be determined by the usual methods. Iron and copper can be determined by the regular analytical methods after decomposition of the plating solution with sulphuric acid.
