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.	Use water spray, foam, powder, carbon dioxide.
EXPLOSION	Above 63°C explosive vapour/air mixtures may be formed.	Above 63°C use a closed system and ventilation.

EXPOSURE
Inhalation	Cough. Sore throat.	Use 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.	Wear safety spectacles or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
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 adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. 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.	EC Classification Symbol: Xn; R: 22; S: (2)-24 UN Classification UN Hazard Class: 9; UN Pack Group: III GHS Classification Signal: Warning Flammable liquid and vapour Harmful if swallowed Harmful in contact with skin Toxic to aquatic life

IMPORTANT DATA

Physical State; Appearance
COLOURLESS-TO-YELLOW LIQUID WITH CHARACTERISTIC ODOUR.

Physical dangers

Chemical dangers
The substance can form explosive peroxides under special conditions. Reacts violently with aluminium, bases, iron, oxidants and phenol. This generates fire and explosion hazard.

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (2b (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 at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.

Effects of short-term exposure
The substance is irritating to the eyes.

Effects of long-term or repeated exposure

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 179°C Melting point: -26°C Relative density (water = 1): 1.05 Solubility in water at 25°C: poor 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.
