TETRASODIUM ETHYLENEDIAMINETETRAACETATE ICSC: 1688 Ethylenediaminetetraacetic acid tetrasodium salt Acetic acid, (ethylenedinitrilo)tetra-, tetrasodium salt N,N'-Ethylenediaminediacetic acid tetrasodium salt EDTA Tetrasodium C10H12N2O8Na4 / ((NaOOCCH2)2NCH2)2 Molecular mass: 380.2 ICSC #    1688 CAS #     64-02-8 RTECS # AH5075000 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. Water spray, foam, powder, carbon dioxide. Explosion Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. Exposure PREVENT DISPERSION OF DUST!  •Inhalation Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •Skin Redness. Protective gloves. Rinse skin with plenty of water or shower.  •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. Abdominal pain. Diarrhoea. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Separated from strong oxidants,strong bases.
