International Chemical Safety Cards GLYPHOSATE ICSC: 0160 N-(Phosphonomethyl)glycine C3H8NO5P/ HOOCCH2NHCH2PO(OH)2 Molecular mass: 169.1 ICSC #    0160 CAS #     1071-83-6 RTECS # MC1075000 EC #         607-315-00-8 April 19, 2005 Peer reviewed 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. NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent build-up of electrostatic charges (e.g., by grounding). Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Avoid inhalation of fine dust and mist. Fresh air, rest.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •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 Burning sensation in the throat and chest. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Do NOT induce vomiting. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into plastic containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs . Well closed. Do NOT store in galvanized steel or unlined steel containers. Store in an area without drain or sewer access. Do not transport with food and feedstuffs.

International Chemical Safety Cards GLYPHOSATE ICSC: 0160 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including nitrogen oxides , phosphorus oxides . Attacks iron and galvanized steel. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: INHALATION RISK: A harmful concentration of airborne particles can be reached quickly on spraying. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes and is mildly irritating to the skin. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point (decomposes): below 234°C Density: 1.7 g/cm3 Solubility in water, g/100 ml at 25°C: 1.2 Vapour pressure, Pa at 20°C: negligible Octanol/water partition coefficient as log Pow: -1.0 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal. N O T E S Sodium, potassium and amine salts are readily soluble in water. Roundup (for the monoisopropyl ammonium salt) and Polado (for the sesquisodium salt) are trade names. Carrier solvents used in commercial formulations may change physical and toxicological properties. ADDITIONAL INFORMATION ICSC: 0160 GLYPHOSATE (C) IPCS, CEC, 1994
