International Chemical Safety Cards GUANIDINE NITRATE ICSC: 0561 Guanidine mononitrate Guanidinium nitrate CH6N4O3 / CH5N3•HNO3 Molecular mass: 122.1 ICSC #    0561 CAS #     506-93-4 RTECS # MF4350000 UN #        1467 October 18, 2005 Validated TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Explosive. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. NO contact with flammable substances. Water in large amounts. EXPLOSION Risk of fire and explosion. Do NOT expose to friction or shock. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Sore throat. Cough. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Pain. Protective gloves. First rinse with plenty of water, then remove contaminated clothes and rinse again.  •EYES Redness. Pain. Safety goggles . First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area and consult an expert in case of large spill. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Do NOT absorb in saw-dust or other combustible absorbents. Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Fireproof. Store in an area without drain or sewer access. Separated from combustible and reducing substances. UN Hazard Class: 5.1 UN Packing Group: III SEE IMPORTANT INFORMATION ON BACK ICSC: 0561 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.
