AMMONIUM PICRATE ICSC: 1631 Phenol, 2,4,6-trinitro-,ammonium salt Ammonium carbazoate NH4C6H2N3O7 Molecular mass: 246.14 ICSC #    1631 CAS #     131-74-8 UN #        0004 EC #         609-010-00-5 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Many reactions may cause fire or explosion. See notes NO open flames. Water in large amounts, water spray. Powder, carbon dioxide. Explosion Risk of explosion on shock or friction and on contact with reducing agents 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 Burning sensation. Cough. See Ingestion. Ventilation (not if powder), local exhaust, or breathing protection. Fresh air, rest.  •Skin Redness. Roughness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •Eyes Redness. Pain. Blurred vision. Safety goggles . First rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.  •Ingestion Abdominal pain. Diarrhoea. Headache. Dizziness. Nausea. Vomiting. Weakness. Red urine. Do not eat, drink, or smoke during work. Rinse mouth. Give one or two glasses of water to drink. Spillage Disposal Storage Packaging & Labelling Consult an expert! Evacuate danger area! Personal protection: particulate filter adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Separated from incompatible materials See Chemical Dangers. Store in an area without drain or sewer access. R: 3-23/24/25 S: 1/2-28-35-37-45 UN Hazard Class: 1 Signal: Danger Expl-Excl mark Explosive; mass explosion hazard Causes serious eye irritation Harmful to aquatic life AMMONIUM PICRATE ICSC: 1631 Important Data Physical State; Appearance: RED OR YELLOW CRYSTALS . Physical Dangers: Chemical Dangers: May decompose explosively on shock, friction, or concussion. May explode on heating. On combustion, forms toxic gases including nitrogen oxides. Reacts violently with metals and reducing agents causing fire and explosion hazard. Reacts with concrete and plaster to produce salts of picric acid, more sensitive to shock than ammonium picrate. Occupational Exposure Limits: TLV not established. MAK not established. Routes of Exposure: The substance can be absorbed into the body by inhalation and by ingestion. Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of Short-Term Exposure: The substance is irritating to the skin and the eyes. The substance may cause effects on the blood, resulting in destruction of blood cells and acidosis. o acid picric Effects of Long-Term or Repeated Exposure: Repeated or prolonged contact with skin may cause dermatitis. Physical Properties Melting point (decomposes): 265°C Density: 1.72 g/cm3 Solubility in water, g/100 ml at 20°C: 1.1 . Octanol/water partition coefficient as log Pow: -1.4 Environmental Data The substance is harmful to aquatic organisms. N O T E S For safety transportation, 10-20% water is usually added. In normal conditions: combustible; if oxidized may become explosive. Other UN number is 1310, with not less than 10% water by mass, hazard class 4.1, packing group I+II.
