FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION
  • Blue lips or finger nails. Blue skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconsciousness.
    Ventilation (not if powder). Local exhaust or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Redness. Pain (see Inhalation).
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
  • Redness. Pain.
    Safety goggles, 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
  • (See Inhalation).
    Do not eat, drink, or smoke during work.
    Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting (extra personal protection: P2 filter respirator for harmful particles).
    Dry.

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS HYGROSCOPIC CRYSTALS.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes slowly on contact with moisture. Upon heating, toxic fumes are formed. The solution in water is a weak acid.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


    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 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly by dispersing.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the red blood cells , resulting in formation of methaemoglobin. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact may cause skin sensitization.
    PHYSICAL
    PROPERTIES
    Melting point (decomposes): (see Notes) 151-152C
    Relative density (water = 1): 1.7
    Solubility in water, g/100 ml at 17C: 83
    ENVIRONMENTAL
    DATA

    N O T E S
    Some references give a melting point (under decomposition) of 151-152C, while one of them contains a warning for explosion on heating above 115C. Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
