EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION
    		• Blue lips or finger nails. Blue skin. Cough. Dizziness. Headache. Laboured breathing. Sore throat.
    		Local exhaust or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Redness. Pain (further see Inhalation).
    		Protective gloves. Protective clothing.
    		Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid.
  • EYES
    		• Redness. Pain.
    		Safety goggles, face shield, 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
    		• Abdominal pain. Blue lips or fingernails. Blue skin. Dizziness. Headache. Laboured breathing. Sore throat. Unconsciousness.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Do NOT wash away into sewer. Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: self-contained breathing apparatus).
    		Separated from combustible and reducing substances, strong oxidants, strong bases, strong acids, food and feedstuffs. Tightly closed. Cool. Dry. Keep in a well-ventilated room.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     YELLOW CRYSTALS , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic fumes (nitrogen oxides). Reacts violently with strong oxidizers or sulfuric acid causing fire and explosion hazard. Attacks some forms of plastics, rubber and coatings.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as TWA): 2 ppm; 11 mg/m3 (skin) (ACGIH 1991-1992).
    OSHA PEL: TWA 5 ppm (30 mg/m3) skin
    NIOSH REL: TWA 2 ppm (11 mg/m3) skin
    NIOSH IDLH: 200 ppm


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its aerosol, through the skin 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. The substance may cause effects on the blood , resulting in formation of methaemoglobin. Exposure may result in death. The effects may be delayed (see Notes). Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the liver and kidney , resulting in injury.
    PHYSICAL
    PROPERTIES
    Boiling point: 238°C
    Melting point: 53-54°C
    Relative density (water = 1): 1.29
    Solubility in water: none
    		 Vapour pressure, kPa at 65°C: 0.173
    Relative vapour density (air = 1): 4.72
    Flash point: 106°C
    Octanol/water partition coefficient as log Pow: 2.41
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to water.
    NOTES
    Explosive limits are unknown in literature. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. The relation between odour and the occupational exposure limit cannot be indicated.
