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, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Lethargy. Headache.  Use closed system or ventilation.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety goggles, face shield 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.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
COLOURLESS SOLID IN VARIOUS FORMS WITH CHARACTERISTIC ODOUR. TURNS PURPLE ON EXPOSURE TO AIR. 

Physical dangers
 

Chemical dangers
On combustion, forms toxic gases. The solution in water is a weak base. Reacts with strong oxidants. 

Occupational exposure limits
TLV: (skin); A1 (confirmed human carcinogen); (ACGIH 1996).
MAK: Carcinogen category: 1; Skin absorption (H); (DFG 2006). 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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. The substance may cause effects on the bladder. This may result in blood in the urine. 

Effects of long-term or repeated exposure
This substance is carcinogenic to humans.
