EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• (See Ingestion).
    		Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN

    		• Protective gloves.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES

    		• Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Headache. Dizziness. Abdominal cramps. Nausea. Vomiting. Convulsions. Tremors.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).
    		Separated from food and feedstuffs. Well closed.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     ODOURLESS WHITE CRYSTALS OR CRYSTALLINE POWDER.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on burning producing toxic fumes including nitrogen oxides.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance may cause effects on the central nervous system and cardiovascular system , resulting in insomnia, excitement, tachycardia, polyuria.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Animal tests show that this substance possibly causes toxic effects upon human reproduction.
