TYPES OF
HAZARD /
EXPOSURE 		ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN!   
Inhalation Cough.  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.  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.  Rinse mouth. Refer for medical attention .

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

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes including hydrogen chloride. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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 spraying or dispersing, however, much faster. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in liver impairment. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 275-277°C
Melting point: 86°C
Relative density (water = 1): 1.8
Solubility in water: none
Vapour pressure, Pa at 25°C: about 2
Relative vapour density (air = 1): 8.6
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00
Octanol/water partition coefficient as log Pow: 5.03/5.63   		The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, milk, plants and mammals. The substance may cause long-term effects in the aquatic environment. This substance may be hazardous to the environment. Special attention should be given to its persistence in soil and its adsorption into sediments. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
