EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
  • Headache. Nausea. Vomiting. Weakness. Chills. Fever. Symptoms may be delayed (see Notes).
    Local exhaust or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN

  • Protective gloves.

  • EYES

  • Safety goggles or eye protection in combination with breathing protection if powder.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Abdominal pain. Nausea. Vomiting.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Refer for medical attention.
    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: P2 filter respirator for harmful particles).

    PHYSICAL STATE; APPEARANCE:
    ODOURLESS WHITE POWDER OR CRYSTALS.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    Reacts violently with aluminium and magnesium powders, and with chlorinated rubber on heating causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: ppm; 5 mg/m3 (as TWA) as fume; 10 mg/m3 (STEL) as fume (ACGIH 1994-1995).
    TLV (as dust): ppm; 10 mg/m3 (as TWA) (ACGIH 1994-1995).
    MAK: ppm; 5 mg/m3; Dust III,5a (1993).


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the respiratory tract. Inhalation of dust or fume may cause metal fume fever. The effects may be delayed. See Notes.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation exposure may cause asthma.
    PHYSICAL
