TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Liquid formulations containing organic solvents may be flammable.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   AVOID EXPOSURE OF (PREGNANT) WOMEN!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  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.  Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Do NOT wash away into sewer. 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
No data. 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes of hydrogen chloride (see ICSC 0163), nitrogen oxides and cyanides. 

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
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
Animal tests show that this substance possibly causes malformations in human babies. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 168°C
Density: 1.26 g/cm³
Solubility in water, g/100ml at 25°C: 0.02
Vapour pressure at 20°C: negligible
Octanol/water partition coefficient as log Pow: 2.24  
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
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.
Bladex is a trade name.
Card has been partly updated in October 2005.
