UN #: 2842

EC Number: 201-188-9

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 28°C explosive vapour/air mixtures may be formed. Risk of explosion on contact with many substances. See Chemical Dangers.	NO open flames, NO sparks and NO smoking. NO contact with bases, combustible substances or oxidizing agents. Above 28°C use a closed system, ventilation and explosion-proof electrical equipment.	Use powder, foam, carbon dioxide, water spray. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Drowsiness. Unconsciousness.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! Redness.	Protective gloves.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 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	Sore throat. Abdominal pain. Blue lips, fingernails and skin. Further see Inhalation.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention. See Notes.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Ventilation. Remove all ignition sources. Do NOT wash away into sewer. Do NOT absorb in saw-dust or other combustible absorbents. 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 Flammable liquid and vapour Harmful if swallowed or if inhaled Transportation UN Classification UN Hazard Class: 3; UN Pack Group: III
STORAGE
Fireproof. Well closed. Separated from : see Chemical Dangers.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers May explode on heating rapidly to high temperature. Mixtures with strong inorganic alkalis, acids and combinations of amines and heavy metal oxides are shock-sensitive. Decomposes on burning. This produces toxic fumes of nitrogen oxides. Reacts with bases, combustible substances and oxidants. This generates fire and explosion hazard. Attacks some forms of plastic.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, by ingestion and through the skin. Effects of short-term exposure The substance is irritating to the eyes and respiratory tract. The substance may cause effects on the blood. This may result in the formation of methaemoglobin. Exposure at high levels could cause lowering of consciousness. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful contamination of the air will be reached quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance may have effects on the upper respiratory tract, blood, liver and kidneys.
