DIETHYL CARBONATE	ICSC: 1022 (April 2000)
Carbonic acid diethyl ester Ethyl carbonate

CAS #: 105-58-8

UN #: 2366

EC Number: 203-311-1

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Above 25°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong oxidizing agents.	NO open flames, NO sparks and NO smoking. NO contact with strong oxidizing agents. Above 25°C use a closed system, ventilation and explosion-proof electrical equipment.	Use AFFF, alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Nausea. Sore throat.	Use ventilation.	Fresh air, rest.
Skin		Protective gloves.	Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth. Rest.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 3; UN Pack Group: III
STORAGE
Fireproof. Separated from strong oxidants. Cool. Well closed.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. Chemical dangers Reacts violently with strong oxidants. This generates fire and explosion hazard. Attacks many plastics and resins.	Formula: C₅H₁₀O₃ / (C₂H₅O)₂CO Molecular mass: 118.13 Boiling point: 126°C Melting point: -43°C Relative density (water = 1): 0.98 Solubility in water: none 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

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure The substance is irritating to the eyes and respiratory tract.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. Effects of long-term or repeated exposure
