EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• Cough, shortness of breath, sore throat.
    		Local exhaust or breathing protection.
    		Fresh air, rest, and refer for medical attention.
  • SKIN
    		• Redness.
    		Protective clothing.
    		Remove contaminated clothes, rinse and then wash skin with water and soap.
  • EYES
    		• Redness, pain.
    		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
    		• (See Inhalation.)
    		Do not eat, drink, or smoke during work. Wash hands before eating.

    PHYSICAL STATE; APPEARANCE:
     ORANGE RED CRYSTALS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     On combustion, forms toxic gases. The substance decomposes on heating.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established
    OSHA PEL: none
    NIOSH REL: TWA 1 ppm (7 mg/m3)
    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:
     The substance irritates the eyes, the skin and the respiratory tract. Inhalation of dust may cause a decrease in lung function.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the central nervous system and thyroid , resulting in headache, fatigue and leg cramps.
    PHYSICAL
    PROPERTIES
    Decomposes below melting point at 180°C
    Relative density (water = 1): 1.65
    		 Solubility in water: NONE
    ENVIRONMENTAL
    DATA
         		Environmental toxicity:
    NOTES
    The symtoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should never again come into contact with this substance.
