EXPOSURE


  • INHALATION
    		• cough. Sore throat, remember to sequence
    		Local exhaust or breathing protection.
    		Fresh air, rest, and refer for medical attention.
  • SKIN


    		• Wash skin gently with non-abrasive soap.
  • EYES
    		• Redness, pain.
    		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, give plenty of water to drink, and refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers, carefully collect remainder, then remove to safe place (extra personal protection: P1 filter respirator for inert particles).

    PHYSICAL STATE; APPEARANCE:
     YELLOW TO GREEN TO BLUISH-BLACK SOLID IN VARIOUS FORMS .

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating to 2700°C.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 10 mg/m3 (as TWA) (ACGIH 1992-1993)
    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 and by ingestion.

    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:
     The substance irritates the eyes, the skin, and the respiratory tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Melting point (decomposes): 2700°C
    Relative density (water = 1): 3.2
    		Solubility in water: none
    ENVIRONMENTAL
    DATA
    NOTES
    Sublimes at melting point with decomposition.
