TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Stinging sensation.  Wear safety goggles or eye protection in combination with breathing protection.  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. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. 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.  Do not transport with food and feedstuffs.

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and corrosive fumes including hydrogen bromide and nitrogen oxides. Reacts with some metals, amines and alkaline compounds. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Skin absorption (H); Sensitization of skin (SH); (DFG 2006). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

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. Repeated or prolonged contact may cause skin sensitization. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 120-122°C
Relative density (water = 1): 1.1
Solubility in water, g/100ml at 22-25°C: 0.028
Vapour pressure, Pa at 20°C: <0.01
Octanol/water partition coefficient as log Pow: 0.18  
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
