International Chemical Safety Cards DIETHYL CARBONATE ICSC: 1022 DIETHYL CARBONATE Carbonic acid diethyl ester Carbonic ether Ethyl carbonate C5H10O3/(C2H5O)2CO Molecular mass: 118.13 CAS # 105-58-8 RTECS # FF9800000 ICSC # 1022 UN # 2366 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. NO open flames, NO sparks, and NO smoking. NO contact with strong oxidants. AFFF, alcohol-resistant foam, powder, carbon dioxide. EXPLOSION Above 25°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong oxidants. Above 25°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE PREVENT GENERATION OF MISTS! INHALATION Burning sensation. Cough. Nausea. Sore throat. Ventilation. Fresh air, rest. SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. EYES Redness. Pain. Safety goggles or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Rinse mouth. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: self-contained breathing apparatus). Fireproof. Separated from strong oxidants. Cool. Well closed.

International Chemical Safety Cards DIETHYL CARBONATE ICSC: 1022 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour mixes well with air, explosive mixtures are easily formed. CHEMICAL DANGERS: Reacts violently with strong oxidants causing fire and explosion hazard. Attacks many plastics and resins. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 126°C Melting point: -43°C Relative density (water = 1): 0.98 Solubility in water: insoluble Vapour pressure, kPa at 20°C: 1.1 Relative vapour density (air = 1): 4.07 Flash point: 25°C c.c. Auto-ignition temperature: 445°C Explosive limits, vol% in air: 1.4-11.0
