TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Flammable.	NO open flames, NO sparks, and NO smoking.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Above 51°C explosive vapour/air mixtures may be formed.	Above 51°C use a closed system, ventilation.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		AVOID ALL CONTACT!
Inhalation	Cough. Shortness of breath.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest.
Skin	MAY BE ABSORBED! Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Burning sensation.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Remove all ignition sources. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: filter respirator for organic gases and vapours.	T Symbol R: 60-61-10-19 S: 53-45 UN Hazard Class: 3 UN Pack Group: III

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-30GF1-III NFPA Code: H1; F2; R1	Fireproof. Separated from strong oxidants.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

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

Occupational exposure limits
TLV not established.
MAK: 5 ppm, 28 mg/m³; skin absorption (H); Peak limitation category: II(8); Pregnancy risk group: B; (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, by ingestion and through the skin.

Inhalation risk
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance is mildly irritating to the eyes, the skin and the respiratory tract.

Effects of long-term or repeated exposure
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
