TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough.    Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting. Diarrhoea.  Do not eat, drink, or smoke during work.  Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Do NOT let this chemical enter the environment. 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.

EMERGENCY RESPONSE SAFE STORAGE
  Keep in a well-ventilated room. Separated from strong oxidants and strong acids. 

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

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including hydrogen bromide and nitrogen oxides. Decomposes on contact with acids or oxidants. 

Occupational exposure limits
TLV: 10mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2003). 

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

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 mildly irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 158-160°C
Density: 1.55 g/cm³
Solubility in water, g/100ml at 25°C: 0.08
Vapour pressure at 25°C: negligible
Octanol/water partition coefficient as log Pow: 1.88-2.11  
The substance is very toxic to aquatic organisms. 

NOTES
Carrier solvents used in commercial formulations may change physical and toxicological properties.
