EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
    		• Disorder of coordination.
    		Ventilation.
    		Fresh air, rest, artificial respiration if indicated, and refer for medical attention.
  • SKIN
    		• Redness, (further see Inhalation).
    		Protective gloves.
    		Rinse skin with plenty of water or shower, and refer for medical attention.
  • EYES
    		• Redness.
    		Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• (See Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth, and refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area, consult an expert, ventilation, absorb remaining liquid in sand or inert absorbent and remove to safe place, wash away remainder with plenty of water, (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Fireproof, separated from strong oxidants, strong bases, strong acids, tightly closed, dry, keep in a well-ventilated room, under inert gas.

     CRYSTALS , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Upon heating, toxic fumes are formed. Reacts with strong oxidants, strong acids, and strong bases.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 5 ppm; 27 mg/m3 (as TWA) (ACGIH 1990-1991)
    MAK not established.
    OSHA PEL: none
    NIOSH REL: TWA 5 ppm (30 mg/m3)
    NIOSH IDLH: No data


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

    INHALATION RISK:
     A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the skin. The substance may cause effects on liver, kidneys, lungs, and gastro-intestinal tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
