EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• Cough.
    		Local exhaust or breathing protection.
    		Fresh air, rest.
  • SKIN



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



    • SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers. Wash away remainder with plenty of water. Sweep gently to avoid raising dust (extra personal protection: P1 filter respirator for inert particles).

    CHEMICAL DANGERS:

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as Al): ppm; 10 mg/m3 total dust containing no asbestos and <1% crystalline silica (as TWA) (ACGIH 1993-1994).
    PDK: 6 mg/m3 F (USSR 1988).
    MAK: ppm; 6 mg/m3; a (1991).
    OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
    NIOSH REL: See Appendix D
    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 harmful concentration of airborne particles can, however, be reached quickly.

    EFFECTS OF SHORT-TERM EXPOSURE:
     Inhalation of high concentrations of dusts of this substance may cause eyes and upper respiratory tract irritation.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: 2980°C
    Melting point: 2072°C
    Relative density (water = 1): 4.0
    		 Solubility in water: insoluble
    Vapour pressure, kPa at 2158°C: 0.1
    ENVIRONMENTAL
    DATA
    NOTES
    There is a different and hard crystalline form of aluminum oxide which occurs abundantly in nature under the name corundum (CAS 1302-74-5). Other melting points: 2015°C (approx.) (corundum).
