TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
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. Wash hands before eating.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
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. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALLINE POWDER WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes. 

Occupational exposure limits
TLV: 3mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2008). 

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

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
The substance may have effects on the peripheral nervous system. This may result in impaired functions. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 370°C
Melting point: 49-50°C
Relative density (water = 1): 1.27
Solubility in water, g/100ml at 20°C: 0.001
Vapour pressure, Pa at 20°C: 1
Flash point: 220°C c.c.
Octanol/water partition coefficient as log Pow: 4.59  
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.
