TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Above 93°C explosive vapour/air mixtures may be formed.	Above 93°C use a closed system, ventilation.

EXPOSURE		PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!
Inhalation		Ventilation.	Fresh air, rest.
Skin	Dry skin.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes		Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water.	Xn Symbol R: 63 S: (2-)36/37

EMERGENCY RESPONSE	STORAGE
NFPA Code: H1; F2; R0	Separated from strong oxidants. Ventilation along the floor.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID.

Chemical dangers
The substance can presumably form explosive peroxides. Reacts with strong oxidants.

Occupational exposure limits
TLV not established.
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation, 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 long-term or repeated exposure
The liquid defats the skin. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
