TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION
    		• Burning sensation. Cough. Dizziness. Weakness.
    		Local exhaust or breathing protection. Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! (Further see Inhalation).
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
    		• Redness. Pain.
    		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



    • SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: P2 filter respirator for harmful particles).
    		Separated from combustible and reducing substances, food and feedstuffs.

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

    PHYSICAL DANGERS:
     Dust explosion possible if in powder or granular form, mixed with air.

    CHEMICAL DANGERS:
     May explode on heating. The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides , causing fire and explosion hazard. The substance is a strong oxidant and reacts violently with combustible and reducing materials. Mixtures with potassium hydroxide are explosive.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation and through the skin.

    INHALATION RISK:
     A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on dispersion of dust, however, much faster.

    EFFECTS OF SHORT-TERM EXPOSURE:
     Inhalation of high levels may cause metabolism increase.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point (decomposes): 279°C
    Melting point: 113°C
    Relative density (water = 1): 1.48
    Solubility in water, g/100 ml at 25°C: 1.6
    		Vapour pressure, Pa at 20°C: 0.0032
    Flash point: 169°C
    Octanol/water partition coefficient as log Pow: 1.91
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to fish.
    N O T E S
    Depending on the degree of exposure, periodic medical examination is indicated.
