TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible.	NO open flames. NO contact with oxidants.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Risk of fire and explosion on contact with acid(s), oxidants.		In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT GENERATION OF MISTS! STRICT HYGIENE!
Inhalation	Headache. Blue lips or finger nails. Blue skin. Dizziness. Laboured breathing.	Local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	MAY BE ABSORBED! (Further see Inhalation).	Protective gloves. Protective clothing.	Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid.
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. (Further see Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING

IMPORTANT DATA

Physical State; Appearance
YELLOW TO COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Chemical dangers
The substance decomposes on contact with strong oxidants, reducing agents, acids or bases producing toxic fumes, causing fire and explosion hazard. Attacks some forms of plastic, rubber, and coatings. On combustion, forms nitrogen oxides, carbon monoxide.

Occupational exposure limits
TLV: 2 ppm as TWA; (skin); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 2; Germ cell mutagen group: 3B; (DFG 2004).

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

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 substance may cause effects on the blood, resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
The substance may have effects on the liver, blood and testes.

Boiling point: 222°C Melting point: -10°C Relative density (water = 1): 1.16 Solubility in water, g/100 ml at 20°C: 0.044 Vapour pressure, kPa at 20°C: 0.02 Relative vapour density (air = 1): 4.73 Flash point: 95°C c.c. Auto-ignition temperature: 420°C Explosive limits, vol% in air: 1.47-8.8 Octanol/water partition coefficient as log Pow: 2.3	The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.

NOTES

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Depending on the degree of exposure, periodic medical examination is suggested.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
