EC Number: 200-467-2

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Extremely flammable. Vapour/air mixtures are explosive. Risk of fire and explosion on contact with oxidants or incompatible substances. See Chemical Dangers.	NO open flames, NO sparks and NO smoking. NO contact with hot surfaces. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. NO contact with incompatible materials: See Chemical Dangers	Use alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Drowsiness. Dizziness. Euphoria. Vomiting. Headache. Laboured breathing. Unconsciousness.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer immediately for medical attention.
Skin	Redness. Dry skin.	Protective gloves.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.
Eyes	Redness.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Nausea. Vomiting. See Inhalation.	Do not eat, drink, or smoke during work.	Do NOT induce vomiting. Rinse mouth. Give nothing to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria Extremely flammable liquid and vapour Harmful if swallowed May cause drowsiness or dizziness Transportation UN Classification UN Hazard Class: 3; UN Pack Group: I
STORAGE
Fireproof. Separated from oxidants and other incompatible materials. See Chemical Dangers. Cool. Keep in the dark. Store only if stabilized. See Notes. Ventilation along the floor.
PACKAGING
Airtight.

DIETHYL ETHER

ICSC: 0355

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance VERY VOLATILE COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated. Chemical dangers The substance can form explosive peroxides under the influence of light and air. Reacts violently with halogens, interhalogens, sulfur compounds and oxidants. This generates fire and explosion hazard. Attacks plastics and rubber.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour and by ingestion. Effects of short-term exposure The substance is mildly irritating to the eyes and respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. The substance may cause effects on the central nervous system. This may result in narcosis.	Inhalation risk A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the central nervous system. May cause addiction.
