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, foam, powder, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles or eye protection in combination with breathing protection.  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. Give one or two glasses of water to drink. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALLINE POWDER. 

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

Chemical dangers
Upon heating, toxic fumes are formed. Decomposes on heating. This produces toxic fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 225-227°C
Density: 1.3 g/cm³
Solubility in water: none
Vapour pressure, Pa at 20°C: 8.1x10-7
Octanol/water partition coefficient as log Pow: 2.1  
The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
The substance is combustible but no flash point is available in literature.
If the substance is formulated with solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Card has been partly updated in October 2005.
