HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough.  Use local exhaust.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING

IMPORTANT DATA
Physical State; Appearance
WHITE OR COLOURLESS FLUFFY CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating and under the influence of UV light. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and nitrogen dioxide (see ICSC 0930). 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
May cause mechanical irritation. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 208°C
Melting point: 148-150°C
Density: 1.85 g/cm³
Solubility in water, g/100ml at 25°C: 0.04 (none)
Vapour pressure at 25°C: negligible
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 
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.
