EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION

    		• Local exhaust or breathing protection.
    		Fresh air, rest.
  • 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

    		• 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 (extra personal protection: P1 filter respirator for inert particles).

    PHYSICAL STATE; APPEARANCE:
     ODOURLESS, TASTELESS, WHITE OR YELLOWISH CRYSTALS OR POWDER.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Reacts violently with aluminium powder.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; 10 mg/m3 (ACGIH 1996).
    OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
    NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp)
    NIOSH IDLH: No data


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

    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:

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Lungs may be affected by repeated or prolonged exposure to dust particles , resulting in baritosis (a form of benign pneumoconiosis).
    PHYSICAL
