UN #: 2389

EC Number: 203-727-3

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Extremely flammable. Vapour/air mixtures are explosive.	NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.	Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Chest tightness. Shortness of breath. Laboured breathing.	Use closed system or breathing protection.	Fresh air, rest. Half-upright position. Administration of oxygen may be needed. Refer immediately for medical attention.
Skin	Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Redness. Pain.	Wear 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 refer for medical attention.
Ingestion	See Notes.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Do NOT wash away into sewer. 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 DANGER Extremely flammable liquid and vapour Toxic if inhaled Suspected of causing genetic defects May cause cancer May cause damage to liver and kidneys through prolonged or repeated exposure Harmful to aquatic life with long lasting effects Transportation UN Classification UN Hazard Class: 3; UN Pack Group: I
STORAGE
Fireproof. Well closed. Cool. Keep in the dark. Store only if stabilized. Separated from strong oxidants and acids. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.
PACKAGING
Airtight.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance CLEAR COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. TURNS BROWN ON STANDING. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. Chemical dangers Contact with air generates explosive peroxides. Reacts with oxidants and acids. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure The substance may be irritating to the skin, eyes and respiratory tract. Exposure could cause severe lung damage. See Notes.	Inhalation risk A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance may have effects on the liver and kidneys. This may result in impaired functions. This substance is possibly carcinogenic to humans. May cause genetic damage in humans.
