	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	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.

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
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 .

PHYSICAL & CHEMICAL INFORMATION
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.	Formula: C₃Cl₃N₃ Molecular mass: 184.4 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

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. 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.	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 long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma.

OCCUPATIONAL EXPOSURE LIMITS
MAK: 0,0076 mg/m³, 0,001 ppm; peak limitation category: I(2); pregnancy risk group: C; sensitization of skin (SH)

ENVIRONMENT

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 by an authorized person, 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.
