TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Flammable.	NO open flames, NO sparks, and NO smoking.	Alcohol-resistant foam, dry powder, carbon dioxide.
EXPLOSION	Above 49°C explosive vapour/air mixtures may be formed.	Above 49°C use a closed system, ventilation, and explosion-proof electrical equipment.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT GENERATION OF MISTS!
Inhalation	Cough. Sore throat. Drowsiness. Dullness. Headache.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Dry skin.	Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Nausea. Vomiting. Diarrhoea. Dizziness. Drowsiness.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention.

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. (Extra personal protection: filter respirator for organic gases and vapours.)	Xn Symbol R: 10-20 S: (2-)24/25 UN Hazard Class: 3 UN Pack Group: III

EMERGENCY RESPONSE	STORAGE
NFPA Code: H2; F2; R0; Transport Emergency Card: TEC (R)-30GF1-III	Fireproof. Separated from strong oxidants. Well closed.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.

Chemical dangers
Reacts with oxidants, bases and reducing agents.

Occupational exposure limits
TLV: 50 ppm as TWA (ACGIH 2000).

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

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

Effects of short-term exposure
The substance is mildly irritating to the eyes and the skin. The vapour is irritating to the respiratory tract. Exposure at high levels may result in lowering of consciousness.

Effects of long-term or repeated exposure
The liquid defats the skin.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 144-146°C Melting point: -33°C Relative density (water = 1): 0.8 Solubility in water, g/100 ml at 20°C: very poor Vapour pressure, kPa at 20°C: 0.7 Relative vapour density (air = 1): 3.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01 Flash point: 49°C Auto-ignition temperature: 430°C Explosive limits, vol% in air: see Notes

NOTES

Explosive limits are unknown in literature, although the substance is combustible and has a flash point 61°C.
