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. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID ALL CONTACT!   
Inhalation See Effects of long-term or repeated exposure. See Notes.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED!  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles 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 refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

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

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic gases. Reacts with strong reducing agents. This generates toxic hazard. 

Occupational exposure limits
TLV: (skin); A2 (suspected human carcinogen); (ACGIH 2004).
MAK: Carcinogen category: 2; Skin absorption (H); (DFG 2004). 

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 irritating to the eyes. 

Effects of long-term or repeated exposure
This substance is probably carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 340°C
Melting point: 114°C
Solubility in water: very poor
Flash point: 143°C c.c.
Octanol/water partition coefficient as log Pow: 3.77  
The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 

NOTES
Similar substances have caused methemoglobinemia, but there are no data available for this substance.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
