EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• Cough. Sore throat.
    		Local exhaust or breathing protection.
    		Fresh air, rest.
  • SKIN
    		• Redness.
    		Protective gloves.

  • EYES
    		• Redness. Pain.
    		Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION

    		• Do not eat, drink, or smoke during work.
    		Rinse mouth.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P1 filter respirator for inert particles).
    		Do not store in aluminium containers.

    PHYSICAL STATE; APPEARANCE:
     ODOURLESS WHITE OR COLOURLESS CRYSTALS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on burning producing toxic and corrosive fumes of nitrogen oxides and chlorine (see ICSC # 0126). Solutions are corrosive to aluminum, iron, and tin.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body through the skin and by ingestion.

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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin and the respiratory tract.


    PHYSICAL
    PROPERTIES
    Melting point: 151-152°C
    Solubility in water, g/100 ml at 20°C: poor
    		 Vapour pressure, Pa at 25°C: 0.002
    ENVIRONMENTAL
    DATA
         		Avoid release to the environment in circumstances different to normal use.
    N O T E S
    Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Lontrel and Matrigon are trade names.
