SODIUM METHYLATE ICSC: 0771 Sodium methoxide Sodium methanolate CH3ONa Molecular mass: 54.0 ICSC #    0771 CAS #     124-41-4 RTECS # PC3570000 UN #        1431 EC #         603-040-00-2 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Highly flammable. Many reactions may cause fire or explosion. NO open flames, NO sparks, and NO smoking. NO contact with water. NO water. NO hydrous agents. Dry powder. Dry sand. Explosion Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water. Exposure PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •Inhalation Sore throat. Cough. Burning sensation. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes). Local exhaust. Breathing protection. Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.  •Skin Redness. Pain. Serious skin burns. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.  •Eyes Redness. Pain. Burns Face shield and eye protection in combination with breathing protection. Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.  •Ingestion Sore throat. Burning sensation in the throat and chest. Shock or collapse. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention. Spillage Disposal Storage Packaging & Labelling Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Cover the spilled material with dry sand. Sweep spilled substance into dry covered plastic containers. Carefully collect remainder, then remove to safe place. Do NOT wash away into sewer. Cool. Dry. Fireproof. Separated from strong oxidants, strong acids, food and feedstuffs . Well closed. Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs. F symbol C symbol R: 11-14-34 S: 1/2-8-16-26-43-45 UN Hazard Class: 4.2 UN Subsidiary Risks: 8 UN Packing Group: II Signal: Danger Flame-Corr Heating may cause a fire Causes severe skin burns and eye damage SODIUM METHYLATE ICSC: 0771 Important Data Physical State; Appearance: WHITE HYGROSCOPIC POWDER Physical Dangers: Dust explosion possible if in powder or granular form, mixed with air. Chemical Dangers: Heating may cause violent combustion or explosion. Reacts violently with water producing flammable methanol and corrosive sodium hydroxide. The substance may ignite spontaneously on contact with moist air. The substance is a strong reducing agent and reacts violently with oxidants. The substance is a strong base, it reacts violently with acid and is corrosive. Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001). Occupational Exposure Limits: TLV not established. MAK not established. Routes of Exposure: Serious local effects by all routes of exposure. Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed Effects of Short-Term Exposure: The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of aerosol may cause lung oedema (see Notes). Medical observation is indicated. Effects of Long-Term or Repeated Exposure: Physical Properties Melting point (decomposes): 127°C Density: 1.3 g/cm3 Solubility in water: reaction Auto-ignition temperature: 70-80°C Explosive limits, vol% in air: 7.3 - 36 Environmental Data N O T E S Reacts violently with fire extinguishing agents such as water. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. Rinse contaminated clothes (fire hazard) with plenty of water. Other UN number is UN1289 Sodium methylate solution in alcohol, hazard class: 3, subsidiary risk: 8, Packaging group II,III.
