EXPOSURE
PREVENT DISPERSION OF DUST!

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

    		• Protective gloves.
    		Rinse skin with plenty of water or shower.
  • EYES

    		• Safety spectacles, 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



    • 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:
     WHITE OR SLIGHTLY GRAY POWDER

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Reacts violently with strong reducing agents.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as tin): 2 mg/m3 (ACGIH 1997).


    		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:
     The aerosol of this substance irritates the respiratory tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Lungs may be affected by repeated or prolonged exposure to dust particles , resulting in a benign pneumoconiosis (stannosis).
    PHYSICAL
    PROPERTIES
    Sublimation point: 1800-1900░C
    Melting point: 1127░C
    		 Density: 6.95
    Solubility in water: none
    ENVIRONMENTAL
    DATA
    N O T E S
    Also called 'flowers of tin'. Occurs in nature as the mineral cassiterite. The commercial grade is also known as 'polishing powder', 'putty powder', or 'tin ash'.
