|ETHYLENE OXIDE||ICSC: 0155|
|CAS #: 75-21-8||1,2-Epoxyethane
| UN #: 1040
| EINECS #: 200-849-9
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Extremely flammable. Gas/air mixtures are explosive. Risk of fire and explosion as a result of decomposition when heated.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, alcohol-resistant foam, water spray, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Cough. Drowsiness. Headache. Nausea. Sore throat. Vomiting. Weakness.||Use closed system or ventilation.||Fresh air, rest. Refer for medical attention.|
|Skin||MAY BE ABSORBED! Frostbite. Redness. Pain.||Protective gloves. Cold-insulating gloves. Protective clothing.||Remove contaminated clothes. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention .|
|Eyes||Redness. Pain. Blurred vision.||Wear eye protection in combination with breathing protection.||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. Wash hands before eating.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. Do NOT wash away into sewer. NEVER direct water jet on liquid. Remove gas with fine water spray.||

|PHYSICAL & CHEMICAL INFORMATION|
Physical State; Appearance
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|Occupational exposure limits|
TLV: 1 ppm as TWA; A2 (suspected human carcinogen).
MAK: skin absorption (H); carcinogen category: 2; germ cell mutagen group: 2
|The substance is harmful to aquatic organisms.|
|Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
The symptoms of asthma 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.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
The odour warning when the exposure limit value is exceeded is insufficient.
