TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Water spray, foam, powder, carbon dioxide.
EXPLOSION	Above 63°C explosive vapour/air mixtures may be formed.	Above 63°C use a closed system, ventilation.

EXPOSURE
Inhalation	Cough. Sore throat.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest.
Skin	Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Safety spectacles or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Sore throat.	Do not eat, drink, or smoke during work.	Rinse mouth. Rest.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment.	EU classification Xn Symbol R: 22 S: (2-)24 UN classification UN Hazard Class: 9 UN Pack Group: III GHS classification Signal: Warning Flame-Excl mark Flammable liquid and vapour Harmful if swallowed Harmful in contact with skin Toxic to aquatic life

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-90S1990 NFPA Code: H2; F2; R0	Separated from incompatible materials (See Chemical Dangers). Well closed. Ventilation along the floor. Store in an area without drain or sewer access. Cool. Keep in the dark.

IMPORTANT DATA
Physical State; Appearance COLOURLESS TO YELLOW LIQUID, WITH CHARACTERISTIC ODOUR. Chemical dangers The substance can form explosive peroxides under special conditions. Reacts violently with aluminium, bases, iron, oxidants and phenol causing fire and explosion hazard. Occupational exposure limits TLV not established. MAK: IIb (not established but data is available) (DFG 2005).	Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Inhalation risk No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. Effects of short-term exposure The substance is irritating to the eyes

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 179°C Melting point: -26°C Relative density (water = 1): 1.05 Solubility in water, g/100 ml: (poor) at 25°C Vapour pressure, Pa at 26°C: 133 Relative vapour density (air = 1): 3.7 Flash point: 63°C c.c. Auto-ignition temperature: 192°C Explosive limits, vol% in air: 1.4 Octanol/water partition coefficient as log Pow: 1.48	The substance is harmful to aquatic organisms.

NOTES

Rinse contaminated clothes with plenty of water because of fire hazard.
Check for peroxides prior to distillation; eliminate if found.
