FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS! STRICT HYGIENE!
Inhalation	Burning sensation. Cough. Sore throat. Shortness of breath. See Notes.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Pain. Skin burns.	Protective clothing. Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes	Redness. Pain. Severe deep burns.	Safety goggles, 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	Burning sensation. Abdominal pain. Nausea. Vomiting. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. If liquid: Collect leaking liquid in covered plastic containers. Do NOT let this chemical enter the environment. Chemical protection suit including self-contained breathing apparatus.

IMPORTANT DATA

Physical State; Appearance
YELLOW TO BROWN LIQUID OR COLOURLESS CRYSTALS.

Chemical dangers
The substance decomposes on burning producing toxic gases and irritating fumes. Reacts with acid anhydrides, acid chlorides, bases, oxidants.

Occupational exposure limits
TLV not established.
MAK not established.

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

Inhalation risk
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance is corrosive to the skin the respiratory tract and the eyes. Corrosive on ingestion. Inhalation of an aerosol of this substance may cause lung oedema (see Notes).

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 211.5°C Melting point: 25.4-26°C Density: 0.97 g/cm³ Solubility in water, g/100 ml at 25°C: 0.79 Vapour pressure, Pa at 20°C: 8 Flash point: >112°C c.c. Auto-ignition temperature: 599°C Explosive limits, vol% in air: 1.1-6.4 Octanol/water partition coefficient as log Pow: 2.3	The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish.

NOTES

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in October 2005. See section EU classification.
