TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		NO water. NO hydrous agents. In case of fire in the surroundings, use appropriate extinguishing media.
EXPLOSION

EXPOSURE		AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat.	Use local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
Eyes	Redness. Pain.	Wear 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 refer for medical attention.
Ingestion	Abdominal pain. Burning sensation. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention .

SPILLAGE DISPOSAL	PACKAGING & LABELLING

IMPORTANT DATA

Physical State; Appearance
COLOURLESS CRYSTALS WITH PUNGENT ODOUR.

Physical dangers

Chemical dangers
Decomposes on heating. This produces toxic and corrosive gases. Reacts violently with water. This produces cyanuric acid, hydrochloric acid and heat. Reacts with methanol, dimethylformamide, dimethyl sulfoxide and 2-ethoxyethanol.

Occupational exposure limits
TLV (NOT-ESTABLISHED):.

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

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

Effects of short-term exposure
The substance is severely irritating to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour or fume may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.

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

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 192°C Melting point: 154°C Density: 1.3 g/cm³ Solubility in water: reaction Vapour pressure, kPa at 70°C: 0.3 Relative vapour density (air = 1): 6.4

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 are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Reacts violently with fire extinguishing agents such as water.
Card has been partly updated in October 2004.
