TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Not flammable. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		STRICT HYGIENE!
INHALATION	Abdominal pain. Cough. Dizziness. Headache. Nausea. Sore throat. Vomiting.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
SKIN	MAY BE ABSORBED! Dry skin. Tremors (further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
EYES	Redness. Pain.	Face shield or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION	Abdominal pain. Nausea. Vomiting (further see Inhalation).	Do not eat, drink, or smoke during work.	Do NOT induce vomiting. Rest. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on burning under influence of air, moisture and UV light, producing toxic and corrosive gases including hydrogen chloride and phosgene. Reacts violently with alkali metals, strong bases and many powdered metals producing toxic and explosive gases. Attacks plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 1 ppm; 6.9 mg/m³ (as TWA) (skin) (ACGIH 1994-1995).
MAK: 1 ppm; 7 mg/m³; skin, B (1992).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

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 irritates the eyes and the respiratory tract. The substance may cause effects on the central nervous system, kidneys and liver , resulting in depression of the central nervous system, kidney impairment and liver impairment. Exposure may result in unconsciousness. Exposure may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the central nervous system and liver , resulting in impaired functions.

PHYSICAL
PROPERTIES

Boiling point: 146°C
Melting point: -44°C
Relative density (water = 1): 1.6
Solubility in water, g/100 ml at 20°C: 0.29
Vapour pressure, kPa at 20°C: 0.647

Vapour pressure, Pa at 25°C: 780
Relative vapour density (air = 1): 5.8
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.031
Octanol/water partition coefficient as log Pow: 2.39

ENVIRONMENTAL
DATA

The substance is toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.

N O T E S

Use of alcoholic beverages enhances the harmful effect. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
