TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Flammable.	NO open flames, NO sparks, and NO smoking.	AFFF, alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION	Above 48°C explosive vapour/air mixtures may be formed.	Above 48°C use a closed system, ventilation, and explosion-proof electrical equipment.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE
Inhalation	Cough. Dizziness. Headache. Unconsciousness. Blurred vision.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Dry skin. Redness.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness.	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
Ventilation. Collect leaking and spilled liquid in sealable metal containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: filter respirator for organic gases and vapours.	Xn Symbol R: 10-20/22 S: (2-)24/25 UN Hazard Class: 3 UN Pack Group: III

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-30GF1-III NFPA Code: H1; F2; R0	Fireproof.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Chemical dangers
Reacts with oxidizing materials. Attacks some forms of plastics.

Occupational exposure limits
TLV: 50 ppm as TWA; (ACGIH 2004).

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

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

Effects of short-term exposure
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system. Exposure far above OEL could cause lowering of consciousness.

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

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 151°C Melting point: -35.5°C Relative density (water = 1): 0.8 Solubility in water: poor Vapour pressure, kPa at 25°C: 0.2 Relative vapour density (air = 1): 3.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01 Flash point: 39°C Auto-ignition temperature: 393°C Explosive limits, vol% in air: 1-5.5
