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.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of explosion on contact with many substances.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.  In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. 
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Blue lips, fingernails and skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Further see Inhalation.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING

IMPORTANT DATA
Physical State; Appearance
YELLOW CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including nitrogen oxides even in the absence of air. Reacts with reducing agents, strong bases and oxidants. This generates explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is mildly irritating to the skin. The substance may cause effects on the blood. This may result in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the blood. This may result in formation of methaemoglobin. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 250-300°C
Melting point: 59-61°C
Relative density (water = 1): 1.3 (liquid)
Solubility in water: very poor
Relative vapour density (air = 1): 6.28
Octanol/water partition coefficient as log Pow: 2.0 (calculated) 
The substance is very toxic to aquatic organisms. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Do NOT take working clothes home.
UN number for molten form: UN1600, TEC (R) 61GT1-II.
