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. NO contact with strong oxidizing agents.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Cough.  Use local exhaust. Use breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
RED-TO-BROWN CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic gases including hydrogen bromide (see ICSC 0282) and nitrogen oxides (see ICSCs 0930 and 1311). Reacts violently with strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 3B; Germ cell mutagen group: 3B; (DFG 2007). 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

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

Effects of long-term or repeated exposure
See Notes.
