SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

Powder, carbon dioxide. NO hydrous agents. In case of fire in the surroundings: NO water.
EXPLOSION

In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
EXPOSURE
STRICT HYGIENE!

  • INHALATION
    		• Corrosive. Burning sensation. Cough. Shortness of breath.
    		Local exhaust or breathing protection.
    		Fresh air, rest. Half-upright position. Refer for medical attention.
  • SKIN
    		• Corrosive. Redness. Pain. Blisters.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
    		• Corrosive. Redness. Pain. Severe deep burns.
    		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
    		• Corrosive. Abdominal cramps. 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 STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from food and feedstuffs (see Chemical Dangers). Dry. Well closed.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS CRYSTALS , WITH PUNGENT ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating or on burning producing toxic fumes including hydrogen chloride and nitrogen oxides. Reacts violently with water producing cyanuric acid, hydrochloric acid and heat. Reacts with methanol, dimethylformamide, dimethyl sulfoxide and 2-ethoxyethanol.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

    INHALATION RISK:
     Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

    EFFECTS OF SHORT-TERM EXPOSURE:
     Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of vapour/fumes may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.


    PHYSICAL
    PROPERTIES
    Boiling point: 190°C
    Melting point: 154°C
    Relative density (water = 1): 1.3
    		 Solubility in water: reaction
    Vapour pressure, kPa at 70°C: 0.3
    Relative vapour density (air = 1): 6.4
    ENVIRONMENTAL
    DATA
    N O T E S
    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 spray, by a doctor or a person authorized by him/her, should be considered.
