EMERGENCY RESPONSE SAFE STORAGE
   

IMPORTANT DATA
Physical State; Appearance
PALE YELLOW ODOURLESS POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive gases including carbon oxides, nitrogen oxides and sulfur oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

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


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 180°C
Relative density (water = 1): 1.5
Solubility in water: none
Octanol/water partition coefficient as log Pow: 4.5  
It is strongly advised not to let the chemical enter into the environment because it is persistent. 

NOTES
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
Also consult ICSC # 1183.
