cyan c o SAFETY DATA SHEET <br /> rrhdiort <br /> CYANCOO SODIUM CYANIDE SOLUTION, MINING QUALITY 23-32% BY WT. <br /> Version 3.0 US Print Date: 2/1/2016 <br /> SECTION 10. STABILITY AND REACTIVITY <br /> Materials to Avoid . Under the action of acids(as well as carbon dioxide)hydrocyanic acid is <br /> released which is combustible and may react with air to form explosive gas <br /> mixtures. • Keep away from acidic salts. <br /> Hazardous Decomposition . HCN: Hydrogen cyanide(hydrocyanic acid) <br /> Products <br /> SECTION 11. TOXICOLOGICAL INFORMATION <br /> Sodium Cyanide <br /> Acute Oral Toxicity LD50 Rat: 5 mg/kg <br /> Method: Literature <br /> Acute Dermal Toxicity LD50 Rabbit(female): 11.8 mg/kg <br /> Method: Literature <br /> Skin Irritation Due to acute dermal toxicity, the irritative effect on the skin cannot be <br /> determined. <br /> Eye Irritation Rabbit <br /> Irritating <br /> Repeated Dose Toxicity Ames test Salmonella typhimurium <br /> Negative <br /> Human Toxicity . Inhalation is possible if cyanide is in the form of aerosols, mists, dusts, or <br /> smoke. •Very toxic by inhalation and if swallowed. • Inhaling of(at already <br /> approx. 200 ppm HCN in the air breathed)or swallowing(approx. 200-300 <br /> mg KCN)can result in immediate unconsciousness and death. • Can be <br /> absorbed through the skin. • Poisoning has an effect on the central nervous <br /> system. • Irritating to eyes, respiratory system and skin. • Following long-term <br /> exposure individual cases of thyroid dysfunction have been described with <br /> electroplaters and silver polishers. <br /> SECTION 12.
